WARNING : REPLACE WORN, DAMAGED, OR CUT ELECTRICAL CORDS AND PLUGS IMMEDIATELY.
Do not operate the charger with a damaged AC or DC cable or connector. Do not operate the charger if it has received a sharp blow, was dropped, or was otherwise damaged in any way. Contact your dealer.
**WARNING : DO NOT INSTALL THE CHARGER ON OR NEAR FLAMMABLE MATERIALS. POSITION THE CHARGER ON A FOUNDATION OF STONE, BRICK, CONCRETE OR GROUNDED METAL.
WARNING** : CHARGERS CAN IGNITE FLAMMABLE MATERIALS AND VAPORS. DO NOT USE NEAR FUELS, GRAIN DUST, SOLVENTS, THINNERS, OR OTHER FLAMMABLES.
Proper installation is important to achieve optimum performance and life from the charger and batteries. No minimum distances are specified for mounting clearances, but allow as much free air space around the charger as possible to improve performance. Please refer to the Specifications Section 14 for operating environmental specifications.
The most favorable mounting orientations of the charger are shown in Figure 2-1. For on-board use, the most favorable way to mount the charger is with the charger base bolted to a 0.1 inch (2.5 mm) minimum thick metal plate. This provides both a strong structural mounting and good thermal conductive cooling (examples are shown in Figure 2-1). A poor thermal conductive mounting material such as plastic or wood would be less favorable for cooling.

The charger dimensions and mounting hole locations are shown in Figure 2-2. For off-board use, an optional handle is available for ease in carrying. The charger case also has routing and securing locations for the AC and DC cordsets when they need to be routed to the opposite ends as shown in Figure 2-3.

BATTERY TYPE

This charger contains multiple battery profiles for different battery types (including wet/flooded, AGM, and gel) and capacities of batteries. The charger was factory-configured with the active battery profile that was requested as part of the original order from Lester Electrical. Before (1) using the charger for the first time or (2) using the charger with a battery pack of a different type or capacity, use the ChargerConnect app to verify the proper active battery profile is selected. If the proper battery profile is not available on the charger, the ChargerConnect app can be used to download the appropriate battery profile from the Cloud. If the battery type you will be charging is not available via the ChargerConnect app Cloud (for example, a specific lithium-ion brand or chemistry), contact Lester Electrical for more information. See Section 8 for additional details.
If the active battery profile is changed, mark the charger ratings label or add an additional label or tag.
****CAUTION: THIS CHARGER IS FOR USE ONLY WITH BATTERY SYSTEMS OF THE SAME TYPE AS THE ACTIVE BATTERY PROFILE. BATTERIES IMPROPERLY MATCHED WITH THE CHARGER MAY BURST CAUSING PERSONAL INJURY AND DAMAGE TO THE BATTERIES OR CHARGER.
Battery manufacturers frequently use the same battery cases for different battery types. Wet/flooded batteries have removable cell caps. Water electrolyzed by discharging and charging the battery is replaced through these openings. Sealed (AGM and gel) batteries are generally distinguished by non- removable cell caps. The physical appearance of the battery case is frequently the same as a wet battery, though the cell caps are generally not removable. Refer to the battery manufacturer’s information panel on the battery case to determine the type battery you have. If the information panel is missing or not legible, do not use the battery.
If you have questions regarding which battery profile to select for use with your particular battery pack, contact your dealer for assistance.

OFF-BOARD (SHELF) VERSUS ON-BOARD (BUILT-IN) CHARGERS

This section describes how the charger operates when the charger type is set to Off-Board or On-Board. Based on your application, this setting can be changed via the ChargerConnect app under “System Profile” (see Section 8).
The charger was factory-configured with the active battery profile that was requested as part of the original order from Lester Electrical. The charger was also factory-configured for mounting on-board a battery-powered vehicle/machine or for off-board use in a shelf or portable application per the original order from Lester Electrical. Before (1) using the charger for the first time or (2) using the charger with a battery pack of a different type or capacity, use the ChargerConnect app to verify that the proper active battery profile is selected and that the system settings match your application (see Section 8).

4.1 Off-Board Chargers
Off-board chargers are designed to be used in shelf or portable applications. If the AC input plug is connected to AC power, a new charge cycle automatically starts when the DC output is connected to a battery pack of the proper voltage. Disconnecting and reconnecting AC power while the DC output remains connected to a battery pack WILL NOT automatically start a new charge cycle. Disconnecting the DC output from the battery pack IS REQUIRED to automatically start a new charge cycle.
4.2 On-Board Chargers
On-board chargers are designed to be mounted on electric vehicles/equipment. If the DC output is connected to a battery pack of the proper voltage, a charge cycle automatically starts when the AC input plug is connected to AC power (unless a safety period of time has not passed since the successful completion of the previous charge cycle). Disconnecting the DC output from the battery pack IS NOT REQUIRED to automatically start a new charge cycle.

AC INPUT

****CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK OR FIRE, DISCONNECT AC POWER FROM THE CHARGER BEFORE INSTALLING OR REMOVING UNIT.
The charger has an AC input rating of 100-240 volts, 50-60 hertz, single- phase. The charger has an AC operating range of 85-265 volts, 45-65 hertz. Below 108 volts, the charger may reduce output power.
The charger is equipped with an IEC 60320 C16 inlet for the AC input power as shown. This allows the AC power cordset to be selected with a proper plug compatible with local electrical codes. The AC power cordset wiring must be properly sized for safe operation. For 100-120Vac operation use minimum wire size of 18 AWG (1.0 mm 2 ) and for 220-240Vac operation use a minimum wire size of 18 AWG (1.0 mm2 ). An AC cord clamp is also included to retain the AC power cordset IEC 60320 C15 connector when the connector has the dimensions as shown below. Loosen the screw on the clamp before inserting the C15 connector. Fully insert the connector into the charger inlet and then tighten the AC cord clamp screw to secure the AC power cordset to the charger.

****CAUTION: IF THE IEC 60320 C15 CONNECTOR DIMENSIONS ARE LARGER THAN SHOWN ABOVE, VERIFY CONNECTOR IS PUSHED ALL THE WAY INTO THE CHARGER INLET OR RISK OF FIRE DUE TO LOOSE CONNECTION MAY OCCUR.
The charger must be grounded to reduce the risk of electric shock and is equipped with an IEC 60320 C16 inlet having an equipment-grounding conductor and a grounding socket. The installed AC power cordset must be plugged into an outlet that is properly installed and grounded in accordance with all applicable electrical codes and ordinances.
If this charger includes the UL Listed symbol on its ratings label, it is provided with a cord set for connection to outlets operating at nominal 120 volts (or 240 volts as appropriate). If the input plug does not fit the power outlet, contact Lester Electrical for the proper cord set terminating in an attachment plug of the proper configuration for the power outlet.

**DANGER: NEVER ALTER THE AC POWER CORDSET OR PLUG PROVIDED. IF IT WILL NOT FIT AN OUTLET, OBTAIN THE CORRECT CHARGER IEC AC POWER CORDSET FOR THE OUTLET, OR HAVE A PROPER OUTLET INSTALLED BY A QUALIFIED ELECTRICIAN. IMPROPER CONNECTION CAN RESULT IN A RISK OF ELECTRIC SHOCK.
If an extension cord is necessary, it must be a 3-conductor, 14 AWG (2.0 mm 2 ) minimum, heavy-duty cord with ground. It must also be in good electrical condition and as short as possible, 25 ft (7.6 m) maximum. Make sure that the pins on the plug of the extension cord are the same number, size, and shape as the AC power cordset plug on the charger. The use of an improper extension cord could result in a risk of fire or electrical shock.
Locate all cords so that they will not be stepped on, tripped over, or otherwise subjected to damage, stress, or accidentally disconnected.
CAUTION** : VERIFY THAT THE AC POWER CORDSET IS FULLY ENGAGED IN THE IEC INLET AND CANNOT BE PULLED LOOSE BEFORE USING THE CHARGER.
DANGER: RISK OF ELECTRIC SHOCK! CONNECT THE AC SUPPLY CORD DIRECTLY TO A GROUNDED, 3-WIRE OUTLET. DO NOT TOUCH UNINSULATED PORTION OF DC OUTPUT TERMINALS OR BATTERY TERMINALS. REPLACE DEFECTIVE CORDS, WIRES, OR CONNECTORS IMMEDIATELY.

DC OUTPUT

****WARNING: LEAD-ACID BATTERIES GENERATE EXPLOSIVE GAS. CHARGE ONLY IN WELL VENTILATED AREAS. TO PREVENT ARCING OR BURNING NEAR BATTERIES, DO NOT DISCONNECT THE DC CHARGING CONNECTOR(S) FROM THE BATTERIES WHEN THE CHARGER IS OPERATING. IF THE CHARGE CYCLE MUST BE INTERRUPTED, UNPLUG THE AC POWER CORD BEFORE DISCONNECTING THE DC OUTPUT CONNECTOR(S) FROM THE BATTERIES. KEEP SPARKS, FLAME, AND SMOKING MATERIALS AWAY FROM BATTERIES. TO REDUCE THE RISK OF FIRE, DO NOT USE THE CHARGER NEAR FLAMMABLE MATERIALS OR VAPORS.
Only charge batteries of the same type, voltage, number of cells, and amp-hour capacities listed on the charger ratings label. Before (1) using the charger for the first time or (2) using the charger with a battery pack of a different type or capacity, use the ChargerConnect app to verify that the proper active battery profile is selected (see Section 8).

6.1 Auto Voltage Mode
The 48V and 36V charger models support automatic multi-voltage DC charging, referred to as Auto Voltage Mode (the 24V charger model does not support Auto Voltage Mode). Auto Voltage Mode provides automatic DC output voltage detection and adjustment so that battery packs of both nominal 48V and 36V can be charged with a single charger without any configuration changes needing to be made to the charger when switching between battery packs of different nominal voltages.
When connected to a 48V or 36V charger model with the ChargerConnect app (see Section 8), the “System Profile” screen will include an “Auto Profile” selection box, which provides the following three (3) options:

• OFF: Single voltage mode – you MUST ensure that the nominal DC voltage of the “Active Battery Profile” for the charger matches the nominal DC voltage of the connected battery pack.
• PER VOLTAGE PROFILES: A battery profile is assigned for 48V and a different battery profile is assigned for 36V. The proper battery profile is automatically selected based on the connected battery pack. This mode is primarily used when the charger will be charging both 48V and 36V nominal battery packs where the battery packs are of different types and/or capacities so using the “Scalable Profile” mode is not appropriate.
• SCALABLE PROFILE: The nominal DC voltage of the “Active Battery Profile” is automatically scaled to 48V or 36V based on the connected battery pack.

NOTE: If the charger is currently set to “Per Voltage Profiles” or “Scalable Profile” mode, and you set the “Auto Profile” selection box to “Off”, you MUST ensure that the nominal DC voltage of the “Active Battery Profile” for the charger matches the nominal DC voltage of the connected battery pack via the “Battery Profiles” screen in the ChargerConnect app.
When Auto Voltage Mode is active (either “Per Voltage Profiles” or “Scalable Profile”) the ChargerConnect app “Dashboard” screen provides the status of the proprietary algorithm that executes at the beginning of the charge cycle by displaying the “Auto Battery Voltage Detection” as a status percentage and the “Detected Battery Pack Voltage”.

6.2 DC Output Cordset

The DC output cordset includes a connector, plug, or terminals. The polarity of the charger DC connector/plug/terminals must be the same as the battery connector/receptacle/terminals. The BLACK DC cable must be connected to the battery negative (-), and the WHITE or RED DC cable must be connected to the battery positive (+). The charger will not operate if the polarity is reversed.

WARNING : CHARGER DC CORDSET MUST HAVE A MINIMUM OF 12 AWG WIRE SIZE FOR PROPER HEAT DISSIPATION. TO PREVENT RISK OF FIRE, DO NOT USE SMALLER GAUGE WIRE.
The DC cordset attaches to the external DC terminal block on the charger. Remove the touch proof cover (if pre-installed) to expose the DC terminal block as shown in Figures 6.2-1 and 6.2-2. Based on the DC cordset connector/plug/terminals, use Table 6.2-3 and Figure 6.2-4 to determine the correct Configuration Number, and then attach the DC cordset wires as shown in Figures 6.2-1 or 6.2-2 depending on your charger model number (the model number is located on the ratings label as shown on page 2).

WARNING: DO NOT CONNECT EXTERNAL TEMPERATURE SENSOR OR LOCKOUT WIRES TO THE CHARGERS LISTED IN FIGURE 6.2-2 OR DAMAGE TO THE CHARGER WILL OCCUR.
Torque the screws for the battery connections (Battery Positive and Battery Negative) to 18 in-lbs (2.0 N-m)and the signal connections (external Temp Sense and Lockout or CAN Signals) to 12 in-lbs (1.35 N-m). Place the strain relief over the DC cordset cable/wires on the side of the DC terminal block where the cordset exits.
When individual wires are used for on-board applications, place the foam rubber gasket that comes on the cordset under the strain relief, center the wires, and then tighten the strain relief screws and torque them to 9in-lbs (1 N-m). This prevents the wires from getting pinched on the side of the strain relief when tightened.Replace the terminal block cover and torque the cover screws to 9 in-lbs (1 N-m).

If this DC cordset was factory-installed, the appropriate System Profile was already uploaded to the charger at the factory.

Figure 6.2-4: DC Terminal Block Configurations 4-9

VEHICLE LOCKOUT CONTROL

Some charger models have a lockout/interlock control signal which can be interfaced with the vehicle/equipment to prevent use/movement of the vehicle while the charger is in use. The lockout control signal, available on Terminal 2 on the DC terminal block (see Figure 6.2-1), is internally pulled high through a 10k ohm resistor to battery positive (+) when lockout is not active and is pulled low to < 1 Vdc when lockout is active. The lockout control signal is typically interfaced with the vehicle motor speed controller. If you are uncertain of how to interface the lockout control signal with your vehicle, please contact your vehicle dealer.
****WARNING: DO NOT CONNECT LOCKOUT WIRES TO THE CHARGERS LISTED IN FIGURE 6.2-2 OR DAMAGE TO THE CHARGER WILL OCCUR.
If the charger is configured for on-board use, the lockout control signal will be active while AC power is applied to the charger. If the charger is configured for off-board use, the lockout control signal will be active while a valid battery is connected to the charger. Based on your application, you can configure the charger as onboard or off-board via the ChargerConnect app under “System Profile” (see Section 8).

PROPER CARE OF DEEP-CYCLE LEAD-ACID MOTIVE POWER BATTERIESb

Motive power battery packs are subjected to severe deep-cycle duty on a daily basis. Although these batteries are designed to withstand such duty, the following precautions must be observed to obtain good performance and maximum cycle life.
CAUTION : ALWAYS WEAR PROTECTIVE EYE SHIELDS AND CLOTHING WHEN WORKING WITH BATTERIES. BATTERIES CONTAIN ACIDS WHICH CAN CAUSE BODILY HARM. DO NOT PUT WRENCHES OR OTHER METAL OBJECTS ACROSS THE BATTERY TERMINAL OR BATTERY TOP.
ARCING OR EXPLOSION OF THE BATTERY CAN RESULT.

1. When installing new batteries, be sure the polarity of each battery and the overall battery pack is correct.
   Otherwise, battery and/or charger damage can result.

2. New batteries should be given a full charge before their first use because it is difficult to know how long the batteries have been stored.

3. New batteries and older batteries that have been in storage are not capable of their rated output until they have been discharged and charged a number of times. Consult the manufacturer of your batteries for more information.

4. DO NOT EXCESSIVELY DISCHARGE THE BATTERIES. Excessive discharge can cause polarity reversal of individual cells resulting in complete failure shortly thereafter.

5. Maintain the proper electrolyte level of wet (flooded) batteries by adding water when necessary. Distilled or deionized water is best for battery life. Never allow the electrolyte level to fall below the top of the battery plates. Electrolyte levels lower during discharge and rise during charge. Therefore, to prevent the overflow of electrolyte when charging, it is mandatory that water be added to cells AFTER they have been fully charged – do not overfill. Old batteries require more frequent additions of water than new batteries.

6. Hard crystalline sulfates form when batteries in storage are not maintained in a charged active state.
   Internal self-discharge can bring about the start of this condition in as little as three days in warm temperatures. Batteries not maintained and allowed to sit in storage will self-discharge, sulfate and lose capacity. Repeated charging without using the batteries between charges can recover some of the lost power, range, and life, but some permanent loss should be expected.

7. Cold batteries require more time to fully charge. When the temperature falls below 65°F, the batteries should be placed on charge as soon after use as possible.

8. The tops of batteries and battery hold downs must be kept clean and dry at all times to prevent excessive self-discharge and the flow of current between the battery posts and frame. Electrolyte spilled on batteries never dries or evaporates.

9. All connections to batteries must be maintained clean and tight. Due to heating and discharge rates, bolted connections loosen over time. Re-tighten the connections twice yearly to the torques specified by the battery manufacturers.

10. Follow all operating instructions, cautions, and warnings as specified in this manual, on the charger, in the battery manuals, and in the vehicle manuals.

10.1 Personal Safety Precautions

1. Have someone within the range of your voice and close enough to quickly come to your aid when you work near a lead-acid battery.
2. Ensure that ample fresh water and soap are nearby in case battery acid contacts your skin, clothing, or eyes.
3. Wear complete eye and clothing protection. Avoid touching your eyes while working near a battery.
4. If battery acid contacts your skin or clothing, wash immediately with soap and water. If acid enters your eye, immediately flush your eye with running cold water for at least 10 minutes and get medical attention immediately.
5. NEVER smoke or allow a spark or flame to be in the vicinity of a battery.

3. If the charger must be disconnected from the battery while a charge cycle is in progress, first disconnect the AC power cord from the AC outlet. Do not disconnect the charger DC output connector/plug from the battery while a charge cycle is in progress.
4. The charge cycle 80% point is indicated by the yellow LED beginning to blink quickly.
5. The Finish charge cycle phase is indicated by the solid illumination of the yellow LED. Not all charge profiles include a Finish phase.
6. An extended Balance/Equalize charge cycle phase is indicated by the green “CHARGE COMPLETE” LED beginning to blink quickly. Not all charge profiles include a Balance/Equalize phase.
7. The charger automatically terminates the charge cycle when a battery reaches full charge, which is indicated by [1] the solid illumination of the green LED or [2] the green LED beginning to blink slowly indicating a post-charge phase. The required charge time is affected by numerous factors, including battery amp-hour capacity, depth of discharge, battery temperature, and battery age/usage. (See note below.)
8. Before operating the machine/equipment, disconnect the charger DC output connector/plug from the battery connector/receptacle by firmly grasping both connectors and pulling them straight apart.
   Note: Some Lithium-Ion batteries disconnect the charger from the batteries when the batteries reach full charge.
   In these situations, the “Charge Complete” LED will NOT be illuminated green despite the fact that the charge cycle has completed. Please refer to the State of Charge (SOC) display on the batteries to confirm a full charge.

11.2 On-Board Charger Operation

Below are general instructions. However, specific charger configurations may include alternate functionality.
If the charger was configured for on-board use, follow these operating instructions:

1. Ensure that the vehicle/equipment that the charger is mounted on is turned off.
2. With the charger AC power cord disconnected from the AC outlet, connect the charger DC output connector/plug to the battery connector/receptacle (most likely already connected or hard wired).
3. Connect the charger AC power cord to an appropriate live AC outlet which is indicated by the blue “AC PRESENT” LED turning on. The charger will start automatically as indicated by the yellow “CHARGE STATUS” LED beginning to blink slowly.
4. If the charger must be disconnected from the battery while a charge cycle is in progress, disconnect the AC power cord from the AC outlet. Do not disconnect the charger DC output connector/plug from the battery while a charge cycle is in progress.
5. The charge cycle 80% point is indicated by the yellow LED beginning to blink quickly.
6. The Finish charge cycle phase is indicated by the solid illumination of the yellow LED. Not all charge profiles include a Finish phase.
7. An extended Balance/Equalize charge cycle phase is indicated by the green “CHARGE COMPLETE” LED beginning to blink quickly. Not all charge profiles include a Balance/Equalize phase.
8. The charger automatically terminates the charge cycle when a battery reaches full charge, which is indicated by [1] the solid illumination of the green LED or [2] the green LED beginning to blink slowly indicating a post-charge phase. The required charge time is affected by numerous factors, including battery amp-hour capacity, depth of discharge, battery temperature, and battery age/usage. (See note below.)
9. Before operating the vehicle/equipment, disconnect the charger AC power cord from the outlet.

Note : Some Lithium-Ion batteries disconnect the charger from the batteries when the batteries reach full charge.
In these situations, the “Charge Complete” LED will NOT be illuminated green despite the fact that the charge cycle has completed. Please refer to the State of Charge (SOC) display on the batteries to confirm a full charge.

11.3 Storage Mode Operation

1. Storage Mode is designed to keep your battery maintained during storage periods that last a few weeks to several months at a time.
2. Depending on the battery type and battery profile selected, a storage charge can be a continuous float or a periodic charge mode.
3. Do NOT disconnect the charger from the battery or from the AC power until your machine is needed for use. Disconnecting and reconnecting the charger from the batteries or AC power may start a charge cycle, but disconnection disrupts the storage mode so optimum battery maintenance is not achieved.
4. After several months of storage your batteries should be serviced and the charger reset by disconnecting the DC for Off-Board or the AC for On-Board applications (disconnect AC for a minimum of 10 minutes) before continuing another storage season.

LED INDICATORS

The charger has four (4) LEDs to indicate charger status and fault information. The general functionality of the LEDs is outlined below and explained in the table below. However, specific charger configurations may include alternate LED functionality.
12.1 Charger LED Status
The functionality of the LEDs is outlined below and in the following table.

• AC PRESENT (Blue) – Indicates charger is connected to a live AC inlet.
• FAULT (Red) – Indicates when a charger or battery fault has occurred (see section 12.2 for more information).
• CHARGE STATUS (Yellow) – Indicates charge cycle status.
• CHARGE COMPLETE (Green) – Indicates when a charge cycle completes successfully, when an extended Balance/Equalize charge cycle phase is active, or when a post-charge phase is active. (See note below.)
  FAULT (Red) LED| CHARGE STATUS
  (Yellow) LED| CHARGE COMPLETE
  (Green) LED| DESCRIPTION
  ---|---|---|---
  Solid On| Solid On| Solid On| LED check for a few seconds during charger initialization.
  Off| Slow Blink| Off| Bulk/Start charge cycle phase (constant power or constant current).
  Off| Fast Blink| Off| Absorption/Plateau charge cycle phase (constant voltage). Greater than 80% charged.
  Off| Solid On| Off| Finish charge cycle phase (constant current). Not all charge profiles include a Finish phase.
  Off| Off| Fast Blink| Balance/Equalize phase. An extended charge cycle is occurring because a trigger condition has been met (cycle count, etc). Not all charge profiles include a Balance/Equalize phase.
  Off| Off| Solid On| Charge cycle complete. (See note below.)
  Off| Off| Slow Blink| Charge cycle complete. Post Charge phase (constant voltage float, etc). Not all charge profiles include a Post Charge phase.
  Slow Blink| Slow Blink| Slow Blink| Charger Bluetooth connected to a smart phone or device, LEDs blink at the same time.

Note : Some Lithium-Ion batteries disconnect the charger from the batteries when the batteries reach full charge. In these situations, the “Charge Complete” LED will NOT be illuminated green despite the fact that the charge cycle has completed. Please refer to the State of Charge (SOC) display on the batteries to confirm a full charge.

12.2 CHARGER LED FAULTS

The charger will indicate when a fault occurs by using different patterns of the Fault (Red), Charge Status (Yellow), and Charge Complete (Green) LEDs as explained in the table below. Using the ChargerConnect App, check the diagnostic tab to get a description of the charger fault.

| FAULT (Red) LED| CHARGE STATUS (Yellow) LED| CHARGE COMPLETE
(Green) LED| DESCRIPTION

---|---|---|---|---
Charger| Slow Blink| Off| Off| NO AC – AC power was lost during charging. Charge cycle was halted and will restart when AC power returns.
Slow Blink| Slow Blink| Slow Blink| BLUETOOTH FAULT – Bluetooth communication issue indicated by LEDs blink one at a time in a rotating pattern. Contact Lester Electrical. Unit is still able to charge.
Slow Blink| Slow Blink| Solid On| PROFILE MISMATCH – Charger has detected a battery profile problem.
Slow Blink| Fast Blink| Slow Blink| LOW TEMP – Temperature is too low to start a charge cycle (< -25°C). Charging will start when temperature

increases.

Slow Blink| Fast Blink| Fast Blink| LIMIT FAULT – An over/under limit condition was detected causing charge to stop. Charge may restart if issue was temperature related and readings return to normal.
Slow Blink| Solid On| Slow Blink| INTERNAL HARDWARE FAULT – Contact Lester Electrical.
Slow Blink| Solid On| Solid On| COMMUNICATION – CAN communication failure has occurred.
Fast Blink| N/A| N/A| EXTERNAL HARDWARE FAULT – Charger has detected an open or shorted lockout wire or a temperature probe fault. Unit is still able to charge.
Battery|

Solid On| Solid On| Fast Blink| BATTERY FAULT – Pre-set battery criteria above critical limits and charging stopped.

N/A = Not applicable, LED state does not matter
Disconnecting the charger from the battery always clears a fault. If the charger was factory-configured for onboard use, removing AC power from the charger also clears a fault.
If a fault cannot be cleared after taking appropriate corrective action, contact your dealer for troubleshooting and/or service.

12.3 Remote LED Status and Faults
When an optional bi-color remote LED cable is attached to the external port, the LED functionality is slightly different from the built-in LEDs and is outlined generally below and in the following table. However, specific charger configurations may include alternate Remote LED functionality.

• FAULT (Red) – Indicates when a charger or battery fault has occurred. See ChargerConnect App for fault description.
• CHARGE STATUS (Amber) – Indicates charge cycle status.
• CHARGE COMPLETE (Green) – Indicates when a charge cycle completes successfully, when an extended Balance/Equalize charge cycle phase is active, or when a post-charge phase is active. (See note below.)

FAULT (Red) LED| CHARGE STATUS (Amber) LED| CHARGE COMPLETE (Green) LED| Description
---|---|---|---
| Solid On| | LED check for a few seconds during charger initialization, Solid On and then Off.
| Slow Blink| | Bulk/Start charge cycle phase (constant power or constant current).
| Fast Blink| | Absorption/Plateau charge cycle phase (constant voltage). Greater than 80% charged.
| Solid On| | Finish charge cycle phase (constant current). Not all charge profiles include a Finish phase.
| | Fast Blink| Balance/Equalize phase. An extended charge cycle is occurring because a trigger condition has been met (cycle count, etc). Not all charge profiles include a Balance/Equalize phase.

Note : Some Lithium-Ion batteries disconnect the charger from the batteries when the batteries reach full charge. In these situations, the “Charge Complete” LED will NOT be illuminated green despite the fact that the charge cycle has completed. Please refer to the State of Charge (SOC) display on the batteries to confirm a full charge.

TROUBLESHOOTING

The charger was fully tested and calibrated before leaving the factory. It was delivered ready to charge. If properly installed, the charger should require very little attention. If improper charger operation occurs, it will require repair by a qualified service technician (see section 12.1 for information regarding the Fault LED).

CAUTION : DO NOT OPERATE THE CHARGER IF IT IS DAMAGED OR APPEARS TO BE MALFUNCTIONING. PERSONAL INJURY OR DAMAGE TO THE CHARGER OR BATTERIES MAY RESULT. DO NOT DISASSEMBLE THE CHARGER. CONTACT YOUR DEALER. INCORRECT REASSEMBLY MAY RESULT IN RISK OF ELECTRIC SHOCK OR FIRE.

1. If the charger does not turn on, check for one of the following conditions.
   a. The charger AC power cord is not plugged into a live and/or appropriate AC outlet.
   b. The battery connections are incorrect – battery not connected, reverse polarity, or short circuit.
   c. The battery voltage is too high.
   d. The battery voltage is too low (below 10 volts).

2. If the charger turns off before a battery is fully charged, and a fault condition is not indicated by the Fault LED, this indicates one of the following conditions.
   a. The AC power was interrupted during the charge cycle.
   b. The charger DC output connector was disconnected from the battery during the charge cycle.
   c. The battery has been allowed to sulfate. Charge the battery at least once every three (3) days when the equipment is lightly used. Once sulfation is allowed to take place, it may be partially reduced by returning, temporarily, to daily charging.

3.  A decrease in vehicle/equipment range where the battery loses power faster indicates one of the following conditions.
   a. The electrolyte level in a wet lead-acid battery was allowed to drop below the top of the battery plates.
   If so, add distilled water to just cover the top of the plates immediately upon discovery, and then fill to the proper level with distilled water at the completion of the very next charge cycle.
   b. Use of the vehicle/equipment before the battery has been fully charged and the charger automatically  terminates the charge cycle. This shortens battery life and accelerates the onset of reduced daily range.
   c. The normal wear-out pattern for the battery.

4. A charge cycle running longer than anticipated before terminating indicates one of the following conditions.
   a. An overly-discharged battery.
   b. The charger output may have been reduced due to low AC input voltage, high ambient temperature, or obstructions to cooling airflow.
   c. The amp-hour capacity of the battery is greater than the charger can fully charge in the anticipated amount of time.
