INTRODUCTION

PRODUCT DESCRIPTION
This engine-generator set is designed for unattended remote start operation. It can be operated as part of a fully automatic standby power system or independently as a local start unit in a prime power system. The enginegenerator set is fully tested at the factory prior to shipment to insure proper operation of each individual component as well as the total system’s performance and reliability.
The engine generator set consists of a multi-cylinder, liquid cooled engine nominally operating at 1800 rpm. The generator frequency regulation is maintained by the engine governor to within +/- 1.5 Hz (cps), from no load to rated load for standard mechanical governors and to within +/- .5 Hz or better for units equipped with an electronic governor.

The generator is a single bearing, direct drive, rotating field design. The generator is connected to the engine flywheel via flexible drive disks. Generator set is skid mounted with isolation mounts between the engine and base on all units.
2 customer supplied 12 Volt batteries are required to complete the installation. Battery requirements are listed later under the battery installation section.
Unit Orientation Note: All references used in this manual for unit familiarization, access and component locations on the Generator Set are oriented from a TOP (plan) VIEW with engine at the FRONT and generator to the REAR.
WINCO uses a common junction box for all customer control and power connections (both AC output and DC control). The common electrical junction box is always on the left side at the generator end of the machine.
The engine is controlled and Generator Set operation is monitored for safe operation by a programmable microprocessor based electronic Engine Control Module (ECM) with an LCD digital display. The generator set ECM control is mounted on a vertical pedestal on the right side of the generator. The ECM is programmed with a cycle cranking sequence – 3 cycles of 15 seconds on/15 seconds off, and 5 minute cool-down delay. The cool-down delay can be changed in the field from 0 to 30 minutes by your installer. Other features, timing cycles, set points, and signal output capabilities are possible. Consult factory for procedure and passwords.

NOTICE
These units will automatically transfer if a power outage occurs while running in exercise mode.

GENERATOR SET
Every WINCO generator set has its own unique identity data plate. This data plate identifies the complete unit model number, the system serial number, and has links to the individual components that form the generator set in our factory records. Several of the major components also have their own individual data plates providing additional information to document build data for warranty and replacement parts.

ENGINE
Refer to the engine operators manual for more detailed operation and maintenance information.

CAUTION: EQUIPMENT DAMAGE
Be sure to check the engine oil level frequently as specified in the engine manual.
The engine manufacturer has established an excellent worldwide engine service organization; engine service is available from a nearby authorized dealer or distributor.
The rated power of each engine generator is limited by the temperature, altitude, and all other ambient conditions specified by the engine manufacturer. Engine power may decrease 3½% for each 1000 feet above sea level, and will decrease an additional 1% for each 10 degrees Fahrenheit above 60° Fahrenheit. Units should not be operated in ambient temperature greater than 125° Fahrenheit.

GENERATOR
WINCO generator sets use brushless, AVR (Auto-Voltage Regulator) controlled broad-range generator ends. The generator converts rotational mechanical energy into electrical energy. These WINCO units are equipped with generators manufactured by Cummins Generator
Technology. Each generator ‘end’ has its own data tag. A unique serial number is on the data plate.

MODEL NUMBER STRUCTURE
The WINCO alpha-numerical numbering consists of a base model designation, followed by an options section,separated by a dash mark. The base component of the model numbering system identifies an engine type,engine starting method, fuel type, kilowatt rating, engine manufacturer, and number of generator poles. Following the separation dash mark is the voltage connection.

Please note that some features or packages, such as NFPA level I & II, do not have an indication place in this numbering system. They are issued and built with an M-Spec (i.e. M-10372) number which can be found on the WINCO data tag. When the M-Spec is present,supplemental inserts will accompany this standard manual providing information about the special equipment and features installed. The standard model numbering key that can be used along with the data tag information and/or M-Spec supplements to determine the generator set’s ratings and specifications.

LIFTING THE GENERATOR SET

NOTICE: PERSONAL INJURY
To prevent injury to persons or equipment, observe the following guidelines when lifting the generator:
Due to the different designs, configurations, options,weights, site conditions, and available material handling equipment, specific lifting instructions are not provided for each individual generator set model. General guidelines provided are applicable to the entire generator line. It is the responsibility of the installing party to follow the lifting equipment’s operator’s manual to prevent injury to personnel and damage to the generator. Smaller generator sets may not require use of overhead lifting equipment and may be placed on the pad with basic material handling equipment, i.e. a forklift.

CAUTION
Do not attempt to lift the generator set by the means of the lifting eyes on the engine or generator end. These lifting points are only for the use during the manufacturing process and are designed for lifting of the individual generator set components.

WARNING
NEVER attempt to lift the fuel tank filled with fuel. Sloshing of the fuel can cause a shift in the balance of the fuel tank, making for a DANGEROUS, unbalanced lifting load.
If the generator was shipped on the fuel tank, use the lifting points located on the fuel tank to move the entire generator set into place. DO NOT PLACE FUEL IN THE TANK PRIOR TO LIFTING.

INSTALLATION

WARNING: PERSONAL INJURY PERSONAL INJURY – Before proceeding with the installation, be sure the DSE7310 is in the “stop” position.
Before proceeding with the installation, be sure the Generator MLCB (Main Line Circuit Breaker) is in the ‘OFF’ position and the unit starting battery is disconnected.

GENERAL INFORMATION
This engine-generator set is generally supplied as weather enclosed packages for quick installation on an outdoor concrete pad. They are also available as open skid mounted units for indoor installation in a building or protective enclosure, properly ventilated, supplied by the installer. The factory weather enclosures are acoustical housing intended for outdoor installation only. Factory weather enclosed units are not intended to be used indoors and no support is available to assist in re-engineering finished packaged units.

All versions must be bolted to a solid base for proper operation. A properly designed concrete pad is necessary for stationary operation. A substantial DOT certified trailer is required for mobile applications. Consult a qualified, licensed electrician or contractor to install and wire the gen-set. The installation must comply with all national, state, and local codes.
Before beginning the installation process, recheck the voltage, phase, and amperage rating of the generator
set. Be certain it can handle the intended load and are compatible with the intended loads. Plans for installation should be prepared with proper attention to mechanical and electrical engineering detail to assure a satisfactory system installation.
The information in this manual is offered only as a guide to finalizing your installation plans.

NOTICE
For full service switching of the entire load, the ATS must be ‘SE’ (Service Entrance) rated or must have a properly rated fusible disconnect installed before the ATS to protect the contacts.

ENGINE GENERATOR SET MOUNTING
This engine-generator set is generally supplied as weather-enclosed packages for quick installation on an outdoor concrete pad. They are also available as open skid-mounted units for indoor installation in a building or protective enclosure, properly ventilated, supplied by the installer.
The factory weather enclosures are acoustical housing intended for outdoor installation only. Factory weather-enclosed units are not intended to be used indoors and no support is available to assist in re-engineering finished packaged units. The unit should be mounted to allow ample working room around it. A general rule to follow is to allow 24 inches or more of clearance for maintenance. Follow local codes for clearance from combustible surfaces.

The unit’s main frame must be bolted securely to a solid base. The engine- generator is mounted on channels which are attached with special shock mounts to the main frame. This allows the engine-generator free movement without affecting the base or surrounding equipment.

WARNING: EQUIPMENT DAMAGE

Never mount these engine-generator sets to a wooden base/structure. Over time, the wood will deteriorate and the unit mountings will come loose. These units must be mounted to a steel or concrete base.

VENTILATION REQUIREMENTS

OPEN SKID

WARNING: EQUIPMENT DAMAGE

It is the installer’s responsibility to ensure that there is sufficient cooling air available to prevent the engine and generator from over heating. Damage caused by overheating is not covered by warranty.

Providing proper air movement during your installation planning is essential. You will need to provide a fresh air inlet as well as a hot air outlet (to the outside of protection housing) for proper engine performance. These engine- generator sets are equipped with unit mount radiators and the engine is equipped with a pusher type fan. The hot air from the face of the radiator must be ducted out of the enclosure to ensure proper cooling. Failing to do so will allow the hot air to recirculate around the radiator causing the engine to overheat, resulting in an engine shutdown and damage. If louvers are used in front of the hot air duct to protect the unit from outside weather, the louvers should be 1½ times as large as the area of the radiator face to prevent back pressure.

Foam or other seals can be used to form a tight lip forcing all of the air from the engine fan out of the enclosure.
In addition to a hot air discharge, you must plan a fresh air intake opposite the radiator discharge. Their fresh air inlets should be 1½ to 2 times larger than the radiator face. The extra air inlet area is required to minimize restriction and to provide combustion air for the engine. Do not block fresh air intakes with other equipment as this will result in insufficient air flow to the engine for cooling. Installing them opposite the hot air discharge will allow a sweeping flow of cooling air across the engine, preventing hot spots.

The WINCO installation manual OPM-112 contains additional information on indoor, open skid installations and is available electronically through our website or by requesting a copy from the factory. The unit should be mounted to allow ample working room around it. A general rule to follow is to allow 24 inches or more of clearance for maintenance. Follow local codes for clearance from combustible surfaces.

INSTALLING THE FUEL LINE

WARNING: FIRE DANGER

Connecting rigid fuel line (i.e. steel or copper line) directly to the inlet fuel filter or fuel pump may cause the fuel line to crack during operation creating a serious fire hazard.

The fuel supply should be as close to the engine as possible. This will reduce the installation cost of fuel runs and minimize line losses. The diesel fuel supply should be no more than 3 feet below the fuel inlet on the pump. If your fuel supply is lower than three feet you may have to install an additional lift pump to bring the fuel up to the mechanical fuel pump on the engine.
The information in this manual is offered to assist you in providing the proper fuel for your engine. However, this information is only provided to inform you of the engine’s requirements and assist in making you aware of the decisions you must make. In no case should the instructions or information provided be interpreted to conflict with any local, state, or national codes. If in doubt, always consult your local fire marshal or fuel supplier.
Engine generator sets are properly adjusted before they leave the factory. Connecting a fuel supply with adequate supply volume is critical to reliable operation. Diesel units with optional base mounted fuel tanks are pre-plumbed to the mechanical fuel pump on the engine.
Open skid mounted Diesel units are often supplied with capped inlet and return lines. The use of a sustainable customer supplied flexible fuel line is essential between the engine and fuel supply to provide a vibration break between your fuel supply and the engine.

LUBRICATION
Before starting the engine, check the oil level in the crankcase. If it is low, refill to the full mark with the proper weight/grade of oil as recommended by the engine manufacturer’s maintenance instructions. The necessity of using the correct oil, and keeping the crankcase full, cannot be over emphasized. Failure to use the proper oil and keep the crankcase properly filled will cause excessive engine wear and shorten its useful life.
Winco recommends our 5W-40 fully synthetic heavy duty engine oil to give you maximum cold weather protection while maintaining excellent performance in warmer weather. We have partnered with a national lubrication oil manufacturer to give you access to Winco private branded premium oil available at comparable prices to conventional oils. See your dealer for additional information.

INSTALLING THE BATTERY

CAUTION
In the following battery installation procedure, check to be sure the DSE 7310 MKII is in the “stop” position. This should be your last step before initial start-up.

These units require 4D batteries, The DR600 is 24 volt and requires 2 batteries. The batteries should be rated at a minimum of 1100 CCA. Installation of the highest CCA rated battery, within the correct BCI group, will increase cold weather starting performance. Gel batteries should not be used with the battery tender installed in the generator enclosure.

Installation and servicing of batteries must only be preformed or supervised by personnel knowledgeable of batteries and the required precautions. Keep unauthorized personnel away from batteries.

When installing or replacing batteries, use the proper group/size starting battery. The battery should be a maintenance-free lead acid design. Deep cycle batteries will not work for this application.

CAUTION: PERSONAL DANGER

NEVER dispose a battery in a fire. The battery is capable of exploding.

DO NOT open or mutilate the battery. Released electrolyte is known to be harmful to the skin and eyes and to be very toxic.

These engine-generator sets are all NEGATIVE ground. Be very careful not to connect the battery in reverse polarity, as this may short circuit the battery charging system on the engine.

CAUTION

A battery presents a risk of electrical shock and high short circuit current. The following precautions must be observed when working with batteries:

1. Remove watches, rings, and other metal objects.

2. Use tools with insulated handles.

3. Check both the battery cable ends and the battery posts to be sure they are free of corrosion.

4. Always connect the battery positive cable first
   and then connect the battery negative cable. When removing the battery cables from the battery, reverse the procedure, disconnect the negative first and then the positive cable.

5. Be sure all connections are tight and coat the terminals and cable ends with dialectic grease.

WARNING

The electrolyte is diluted sulfuric acid that is harmful to the skin and eyes. It is electrically conductive and corrosive. The following precautions must always be taken.

1. Always wear full eye protection and protective clothing.
2. Where electrolyte contacts skin, wash off immediately with water.
3. If electrolyte contacts the eyes, flush thoroughly and immediately with water and seek immediate medical attention
4. Spilled electrolyte is to be washed down with an acid neutralizing agent. A common practice is to use a solution of one pound of bicarbonate of soda (baking soda) to one gallon of water. The bicarbonate of soda solution is to be added until the evidence of reaction (foaming) has ceased. The resulting liquid is to be flushed with water and the area dried.

DANGER: EXPLOSIVE FIRE RISK

1. Never smoke when near batteries.
2. Do not cause a flame or spark in the battery area.
3. Always discharge static electricity from your body before touching batteries by first touching a ground metal surface.

SERVICING BATTERIES
Batteries used on these units may, over time, lose water. This is especially true if you are using a trickle charger to maintain your battery. Different types of batteries require various types of maintenance. Refer to the battery manufacturer for specific recommendations.

NOTE: Always make sure that a new battery is fully charged before installing it on a generator set. Failure to do so can cause damage to the engine control module in the generator set.
All connections must be clean and tight. Depending on your battery type, check the electrolyte in the battery periodically to be sure it is above the plates. Never allow the battery to remain in a discharged condition.

CONNECTING BATTERY CHARGER & BLOCK HEATER
A three-stage battery charger is provided standard on this unit. The charger is an Automatic Battery Charger & Maintainer. This charger has three rates of charging. During the first mode, known as Bulk charging, the charging current is limited to 10 Amps at a voltage of up to 14/27 Volts. The yellow LED will be on constantly during this stage. When the charging rate drops to 2.5 Amps, the charge will enter the ABSORPTION charging mode. During this mode, the yellow LED will be flashing. The charging voltage is held at 14/27 Volts and the charging rate gradually reduces the amount of current (Amps) flowing to the battery to 100% charged state. The battery can be left on this mode indefinitely. During this mode, the green LED will be on constantly.
This charger is mounted under the customer connection on the control side of the generator and plugged into the receptacle mounted in the AC connection cabinet. The battery charger receptacle is to be powered by a GFCI circuit and installed in accordance with the United States National Electric Code. It is suggested that this circuit be fused for 15 amps. The block heaters on these units are 3000 watt heater will need to be hard wired in.
The engine block heater installed on this unit should also be hard wired in. The block heater is thermostatically controlled and when plugged in will maintain the engine coolant temperature between 100 and 120 degrees F.

MOUNTING THE AUTOMATIC TRANSFER SWITCH

WARNING: FIRE HAZARD

All wiring must be done by a licensed electrician, and must conform to the National Electrical Code and comply with all the local codes and regulations. Check with the local authorities before proceeding.

INSTALLATION NOTES:
Because of many different types of service, feeder and distribution equipment, no specific wiring instructions can be provided. It is recommended that only copper wire be used. In all cases it is essential that while the load is connected to the generator, there can be absolutely no feedback from the generator to the power line or the power line to the generator. When properly installed, the normal ATS Control and safety system will eliminate all paths and feedback.

To wire the automatic transfer switch into existing wiring, first determine which circuits will be on the emergency load circuit. If the entire load is transferred, the transfer switch can be wired directly after the watt-hour meter and the service entrance, providing the service entrance ampere rating is within the transfer switch’s rated capability.

If only specific circuits are to be powered under emergency power failure conditions, an additional distribution panel designated “emergency distribution panel” must be installed.
All selected emergency circuits are removed from main distribution panels and installed in the emergency distribution panel. The ATS is then installed between the main panel and the emergency distribution panel. Suggested circuits: freezer, refrigerator, furnace, emergency lights, sump pump, emergency outlet circuits, etc. Total running load must not exceed generator rating.

A.C. CONNECTIONS

NOTICE : CLASS 1 WIRING METHODS ARE TO BE USED FOR ALL FIELD WIRING CONNECTIONS TO TERMINALS OF A CLASS 2 CIRCUIT

All wiring must be completed in accordance with the National Electric Code as well as any state and local codes.
You must pay particular attention to wire size requirement for the amperage of service you are dealing with. The table below provides you guidance on wire sizing based on both wire type and amperage. Wire amperages have been derated for 40° C ambient temperatures operation.

WARNING
Make sure the generator is disconnected from the battery to prevent accidental starting.

• NEUTRAL LUGS:
  These lugs are isolated from ground and provided for you to connect your neutral wire from the transfer switch to the generator.

• GENERATOR CIRCUIT BREAKER:

WARNING: PERSONAL INJURY/DEATH

A mainline circuit breaker has been provided inside the generator housing. During all wiring installations, make sure the breaker is in the OFF position and the generator operating switch is in the OFF position.

Your generator is equipped with an electronic circuit breaker. These premium circuit breakers are adjustable allowing you to fine-tune them for your applications. WINCO uses an adjustable breaker, which allows us to use the same breakers in reconnectable units. These adjustments should only be made by a competent technician to prevent equipment damage, injury or death. The following features are adjustable:

Long-Time Protection:

The dial that controls the long-time protection is labeled Ir. The dial correlates with the amperage setting of the long-trip. All the wires should be sized equal to or greater than this dial position. The breaker will not trip at 105% of the dial position current and will trip within two hours of 120% of the dial position.

Short Time Protection:
The dial that controls the short-time protection is labeled Isd (x In). This setting controls the inrush current the circuit breaker will allow. The number on the dial is the current allowable based upon the long-time (Ir) setting of the breakers. For example, if the Ir of the breaker is set at 200 and the Isd is set at 1.5 the short term breaker setting is 250 amps.

Instantaneous Protection:
The dial that controls the instantaneous protection is labeled Ii (x In). The breaker will trip immediately upon reaching this current level. The dial is set as a multiple of the Long-time (Ir) setting.

The circuit breaker has three LED lights on it.

Ready LED (green)
Blinks slowly when the electronic trip unit is ready to provide protection.

Overload Pre-Alarm LED (orange)
Shows a steady light when the load exceeds 90% of the Ir setting.

Overload Alarm LED (red)
Shows a steady light when the load exceeds 105% of the Ir setting.

GROUND LUG:
These ground lugs are bonded to ground and are provided for you to connect your ground wire from the transfer switch to. The lugs will accommodate #6 AWG to 300 MCM and should be torqued to 21 ft. lbs.

NEUTRAL TO GROUND LEAD LUG:
This lug is provided on the neutral terminal block to allow you to run a neutral to ground lead if you are using the generator in a stand alone application. This would be an application where there is not a distribution panel and no other ground to neutral bond in the wiring system. If a grounding wire is attached here, remove the floating neutral label in the panel. This will not be used when you are wiring a generator and transfer switch into an existing power system.

WARNING: EQUIPMENT DAMAGE
When installing a three-phase 240 Volt system, be sure you know which lead is the high voltage “wild” leg (208 Volt line to neutral). The generator normally carries the high voltage on the G2 lead.

All wires should be installed in rigid or flexible conduit (knockouts are provided in the control box).

D.C. CONNECTIONS

All DC connections are completed on the terminal strip just below the engine control. All DC connection must be separate conduit. You cannot mix AC and DC leads at the same conduit.
To install the wires, reference the following picture. Use a small flat head screwdriver to push the release spring inside the square hole (A). While the release is being pushed,insert the wire into the larger circular hole (B). Remove the screwdriver to secure the wire into place.

CONNECTION BOX TERMINALS
Wire size requirements for each of the connections may vary but terminal lugs should be used for all connections.
Torque spec for terminal lugs is 9 in. lbs.

CUSTOMER REMOTE START CONNECTION TERMINALS.
The two remote start leads from the Automatic Transfer Switch are connected to the two terminals marked GROUND & START. The WIRE in terminal GROUND is battery negative and the wire in the terminal labeled START is your remote start lead. Closing these two leads together will signal the DSE 7310 MKII to go into an autostart mode and start up the generator.

Depending on the distance, 14 to 16 gauge standard wire should be used. It is suggested that these wires be labeled S1 (ground) and S2 (start). The terminal blocks are designed to use terminal lugs on all wires and the screws should be torqued to 9.6 in. lbs.

Note: Any relay closure can be used to start and stop this generator. As long as the contact stays closed, the generator set will continue to run. Once the relay is opened, the unit will shut down and remain on standby mode until the remote start relay is closed again.

ESTOP – & ESTOP +.
These two terminals are shipped with a jumper installed.

If your application requires the installation of a Remote Emergency Stop switch, remove the jumper and wire your switch to these terminals. This unit will not start and run without the jumper installed or a remote N/C switch installed.

BATTERY CHARGER FAILURE.
Battery charger failure relay input from remote battery charger to DSE 7310 MKII controller.

REMOTE DISPLAY PANEL INTERFACE TERMINALS.
These interface terminals are pre-wired to allow for the connection of a remote display. This display allows for the remote annunciation of alarms at a location such as a nurse’s station or a control room. This display can be used to meet the remote annunciation requirements of the NFPA 110 standards (this feature meets the annunciation requirements in applications requiring NFPA 110 level on protection).

On gaseous models, the engine timing is controlled by the ECU on the engine and you need to tell it what fuel you want to operate on; LP or NG.

On diesel models, this switch has been disconnected and will do nothing.

PROTECTIONS
When an alarm is present, the common alarm LED if configures will illuminate. The LCD display will show an icon to indicate the failure.

WARNINGS
Warnings are non-critical alarm conditions and do not affect the operation of the generator system, they serve to draw the operator’s attention to an undesirable condition.

Warning alarms are self-resetting when the fault condition is removed. The icon will appear steady in the display.

SHUTDOWN
Shutdowns are critical alarm conditions that stop the engine and draw the operator’s attention to an undesirable condition. Shutdown alarms are latching. The fault must be removed and the STOP/RESET button pressed to reset the module. The icon will be flashing in the display.

INITIAL START UP

WARNING: EQUIPMENT DAMAGE
Before attempting to start this unit, complete your prestart checklist and ensure the generator mainline circuit breaker is in the proper position prior to starting. Starting this unit without it properly connected can cause serious personal injury or equipment damage.
DO NOT jump start these engine-generator sets. Starting these units on a low battery or jump starting them will cause damage to the engine control module.
Use the following check list to verify correct installation before starting the engine.
□ Engine oil. Fill as required with proper grade/qty.
□ Engine coolant. Fill as required with proper mixture.
□ Unit mounting base properly bolted down.
□ Clearance for service and maintenance on all sides.
□ Proper fuel line material and size.
□ All fuel line connections tight.
□ Battery connections clean and tight
□ Battery fully charged.
□ All AC and DC wiring installed and properly protected.
□ Compressor oil. Fill as required with proper grade/qty.
After completing the previous checklist, the enginegenerator set is ready for initial start-up.

MANUAL MODE

1. Press and release the Manual Mode button. The small  LED light next to it should come on.
   Note: There is no start delay in this mode of operation.

2. Press and release the green Start Engine button. The DSE 7310 MKII will send two signals to the engine. The first signal wire #21 will engage the fuel solenoid, the second wire, #22, will engage the starter on the engine.
   At this point the DSE7310 will start the cranking cycle (10 seconds on and 10 seconds off).
   Note: Wire #93 is energized to turn on the glow plugs for 15 seconds first and then the starter and fuel solenoid are engaged.
   If the engine fails to start during this cranking period, the starter motor is disengaged and goes into a rest mode after which a second attempt is made to start the engine. Should this sequence continue through 3 cranking cycles the start sequence will be stopped and the display will show ‘FAILED TO START”.

3. During manual operation, the load will not normally be applied to the generator. But caution must be used, if the line power should fail or be turned off the transfer switch during manual operation the load may be applied to the generator.
   With the engine running smoothly check the no load voltage and frequency on the digital display. The voltage should be 208/240/480 AC depending on which model you have and a frequency of 59.5 to 60.5 hertz (Hz).
   If you have the proper voltage at the generator the next step is to check the voltage at the generator terminals in the Automatic Transfer Switch. The voltage between the G1 and the G3 terminals should be the same as it was on the generator front panel. The voltage should also be checked between the hot terminals (G1 and G3) and the G-N to be certain of a balanced voltage output and a solid neutral connection. The voltage between G1 and G-N should be about 120 volts AC (277 on 480 units). The same approximate voltage should be found between terminals G3 and G-N (120 volts AC).
   On three phase panels the G2 voltage level should also be checked. ON 240 VOLT (DELTA) SYSTEMS BE SURE YOU KNOW WHERE THE HIGH VOLTAGE “WILD” LEG IS. IT MUST BE IN THE SAME LOCATION ON THE LINE SIDE AS IT IS ON THE GENERATOR SIDE.
   (i.e. if it’s on L-3 on the line side it must be on G-3 on the generator side. Also on three phase systems make sure that the rotation is the same on the generator as it is on your line power. Failure to insure proper rotation will cause three phase motors to spin backwards possibly damaging them.
   NOTICE
   If for any reason during the check out procedure the voltage and frequency are not correct, depress the STOP/RESET button and correct the trouble before proceeding.

4. Stopping – There are two ways to stop the unit when it is in the manual mode. Pressing the STOP/RESET button will stop the unit immediately. Pressing the AUTO mode button will stop the unit but only after the cool down timers have timed out and there is no remote start signal being sent to the unit.

AUTO MODE
To activate the automatic start mode you will just need to depress the AUTO button, the LED indicator beside the button confirms that the unit is in automatic mode.
To test the Automatic Transfer Switch, follow the instruction on the operator’s manual that came with the transfer switch. If you get a fault during the initial start up or prior to start up, it is most likely a false warning light. Simply reset the ATS start over.
Once you have completed testing of the ATS, be sure you ALWAYS leave the system in the standby mode,unless servicing the unit. For standby operation, press the AUTO button on the front of the control. The green light should light up next to the AUTO button.
NOTE: For setting the exerciser circuit, for all ATS, see the operator’s manual shipped with the ATS.

MAINTENANCE

CHANGING THE OIL

CAUTION: PERSONAL INJURY
Only change oil when the engine is not running and is at a low temperature in order to avoid the risk of burns.
WINCO recommends our 5W-40 fully synthetic heavy-duty engine oil to give you maximum cold-weather protection while maintaining excellent performance in warmer weather. We have partnered with a national lubrication oil manufacturer to give you access to Winco private branded premium oil available at comparable prices to conventional oils. See your dealer for additional information.

WINCO has plumbed an oil drain valve to the outside of the unit. Attach a customer-supplied 5/8” hose to conveniently run the oil to a drip pan or suitable container for catching the oil.

Oil changes must be done when the engine is hot.

1. Connect the drain hose to the oil drain pump and check that no leakage can occur.
2. Pump the oil out (or remove the bottom drain plug and drain the oil).
3. Remove the drain hose (or install the bottom drain plug).
4. Fill with engine oil.

CHANGING OIL FILTER
The filter must be replaced when the lubricant oil is changed.
Only use filters with a filtering degree equal to the original filter.

CAUTION: PERSONAL INJURY
Only change oil when the engine is not running and is at a low temperature in order to avoid the risk of burns.

1. Remove all oil filters with a suitable oil filter extractor.

2. Clean the mating surface of the oil filter bracket.
   Make sure that no pieces of old oil seal are left behind.
   Carefully clean round the inside of the protective rim on the oil filter bracket.

3. Put a thin layer of engine oil on the seal rings of the new fuel filters.

4. Install the new oil filters. Tighten the filters ¾–1 turn after they touch.

5. Top up with engine oil, start the engine and let it run for 20-30 seconds.

6. Turn off the engine, check the oil level and top up as required.

7. Check sealing round the oil filters.

STORAGE

PREPARING THE ENGINE FOR A LONG PERIOD OF INACTIVITY
In the case of a planned period of inactivity that lasts longer than two months, to prevent the interior parts of the engine and some components of the injection system from oxidizing, prepare the engine as follows:

1. Drain the lubricant oil from the sump after heating the engine.
   Drain the engine oil and fill up with conservation oil to just over the MIN marking on the dipstick.

2. Connect the fuel suction and return hoses to a 1/3 full Jerrycan containing conservation oil and 2/3 diesel fuel.

3. Bleed the fuel system.

4. Start the engine and run at a fast idle until about 2 liters (0.6 US gal) of the fluid in the jerrican have been used. Stop the engine and re-connect the fuel suction and return lines.

5. Drain the conservation oil from the engine.

6. Make sure the coolant has adequate antifreeze properties. Top up as necessary. Alternatively, you can drain the coolant (also drain the coolant filter).

7. Drain any water and contamination from the fuel filters and fuel tank. Fill the fuel tank completely, to avoid condensation.

8. Disconnect the battery cables, clean and charge the batteries. Trickle charge the batteries while the equipment is in storage. A poorly charged battery can freeze and burst.

9. Put a note on the engine with the date, type of conservation and the conservation oil used.

10. Cover the air filter, exhaust pipe and engine if necessary.

11. Empty the AdBlue/DEF tank and rinse it with distilled water.
