CONTROL CONNECTIONS

NOTE:
The transfer switch consists of the 6-position terminal block (shown in Figure 6) for connections.

WARNING
Make sure the disconnects for the LINE (Utility) and AUXILIARY (Generator) are in the OFF position. Once battery (12 Vdc) is applied to the ATS customer terminal  block (BATTERY+ & BATTERY-) the ATS controller will power up to the AUTO MODE. Since the power to the LINE position should be in the OFF position, the ATS  will close RSC1 & RSC2 sending a start signal to the generator. To avoid injury that may be caused by such a start-up, please make sure the generator is in the OFF/DISABLED position on the controller.

Battery + and Battery – must be connected for operation of the DSE controller. Standard is for 12 Vdc connection. For 24 Vdc operation, the relays K1, K2, K3, and K4  would need to be changed to 24 Vdc coils. K3 & K4 on 600A only. Consult factory for kit RONK 26097 (2 relay coils).
RSC1 and RSC2 need to be connected to the remote start/stop connections of the generator to allow automatic starting. These are N.O. dry contacts. 8A, 35 Vdc Max.
An optional customer-supplied test switch may be installed by the customer using the TEST 1 and TEST 2 terminals. A closed circuit between the test connections will simulate a utility failure.

GENERAL OPERATION

RONK ATS GENERAL OPERATION
The ATS switch in combination with the controller module will allow for the automatic transfer of an electrical load to a standby power source in the event of an over/under  voltage or frequency condition on any or all phases of the utility power supply.
In the event of an over/under voltage or frequency condition of utility power, the onboard controller sensing circuitry will begin the initiation of the transfer process. Upon  initial sensing of a loss of utility power, the transfer switch is specifically designed to allow an engine start time delay period (Parameter 502) to expire before starting the  generator. This engine start time delay is user-adjustable from the switch, preventing unnecessary engine starts from a temporary loss of utility. In the event the utility source  is not restored after the engine start time delay has expired, the remote contacts will close, sending a signal to the generator’s automatic start controller.
When the ATS controller senses that the generator has started, and is within acceptable limits, the transfer switch will wait until the utility to generator time delay (Parameter  503) has expired before switching to the generator position. All connected loads will be transferred to the generator power source.
While the transfer switch is in the generator position, the controller will constantly monitor the utility source voltage and frequency status. Once the utility source is restored,  the transfer switch will wait until the generator to utility time delay (Parameter 510) has expired before switching back to the utility position. All connected loads are  transferred to the utility power source.
When connected loads are transferred back to the utility power source, an engine cooldown period (Parameter 511) will be initiated, allowing the generator to run in a no-load condition. This engine cooldown time delay is user-adjustable from the controller, allowing the generator to continue running for an adjustable period after the utility is restored.

QUICKSTART GUIDE

SETTING TIME OF DAY (TOD)
See DSE331 Installation Instructions (DSE Document 053-131) or DSE 331 ATS Controller Operators Manual (DSE Document 057146) for definition of adjustable parameters.

The TOD must be set to local time on initial power up. To do so, enter the configuration mode by pressing and holding the button (approximately 3 sec) until the configuration icon is displayed. Navigate to parameter 1001 by pressing the button twice ( and button advance or decrease by one, advances to the next 100). Press the button again to activate the TOD to be changed, it will begin to flash. Change to the current time using the or buttons (24 hr. clock; only changes by the minute with multiple presses or press and hold). Press the button to save once the correct time is reached. The value will stop flashing.
Navigate to parameter 1002 by pressing the button and set the day of the week in a similar fashion. (1=Mon, 2=Tue, 3=Wed, 4=Thu, 5=Fri, 6=Sat, 7=Sun)
Press and hold the button to exit the configuration mode.

NOTE:
On battery loss to the Automatic Transfer Switch, the TOD must be reset to current time and day when the battery is re-applied.

SCHEDULER
The DSE331 scheduler is the feature that sets the exercise timer for the Automatic Transfer Switch and the generator set.
The ATS comes from the factory with the scheduler pre-set.
If no modifications are made, the ATS will simulate a utility power outage, start the generator, and transfer the load to generator power each Saturday at noon. After ten  minutes of the generator powering the load, the ATS will transfer the load back to utility power. The generator will run through a cooldown period and then be shutdown.
To change the scheduler, configuration parameters 901 through 905 can be modified.

208V SYSTEM SETTINGS
The 200-240V (‘2’ voltage code) Automatic Transfer Switches are factory preset for 240V systems. To apply the ATS to a 208V system, the following configuration  parameters need to be changed.

The 208V settings will result in a switch that will work in a 208V, 3PH, WYE system with the following voltage set points:

2. Set the removable handle on “M” and operate in the UP direction.

The transfer switch is in the utility position when reference A on the contactor is set to the ON position and reference B is set to the OFF position. The transfer switch is in  the generator position when reference A on the contactor is set to the OFF position and reference B is set to the ON position, as seen in 400A Manual Transfer on page 18.
The switch should need to be transferred manually only in the event of a failure within the VTS controls. Please call technical support if any transfer failures are observed.
