5.2 MAIN MENU INTERFACE
In the main screen, press key, and enter the main menu interface.

Press key to choose parameters (the current line was highlighted with black) and then press  key to confirm, and enter the corresponding display screen.

COMMISSIONING

In the main screen, press to enter into the operation interface and the screen will show as below:

 

Press key to select corresponding function, and press key to confirm.
TEST OFF-LOAD: It will send out a start signal immediately. After generator is normal, if mains is normal, the ATS will not act. The ATS will transfer the load to generator only when mains is abnormal. After mains return to normal, the ATS will transfer the load to mains. Here the start generator signal output will keep.
TEST ON-LOAD: It will send out a start generator signal immediately. After generator voltage is normal, the ATS will transfer the load to gens immediately regardless the main is normal or not.
STOP TO TEST: The start generator signal will turn off after pressing this key immediately.
CYCLE START: When this mode is active, generator start-signal will cyclic output according to mains status. The cyclic time can be set by users. If generator fault occurs, start-signal won’t be sent out any more by controller. If in manual mode, controller will keep the current status and cancel cycle start function.
Conditions and procedures for cycle start mode:

1.  In automatic mode.
2. Output setting: 1# engine start output (N/O Output) and 2 # engine start output (N/O Output).
3. Input setting: 1# generator fault input, 2# generator fault input and remote start input.
4. Option of <Cycle run times> and <Cycle shutdown times> should be programmed and run.
5. Set the system type as 1# Gens & 2# Gens.
6. Set the proper <generator start delay> time.

Remark: In manual mode, after choosing commissioning stage, generator will output start-signal immediately, but theATS will not transfer to load automatically except for operation manually by pressing key on the front panel.

ATS OPERATION

13.1 MANUAL OPERATION

Press key and manual operation indicator goes light, and the manual mode is active.

1. Press , 1# close relay outputs immediately, if 1# closing input is active, its indicator lights, and the 1# source connect to load.
2. Press , 2# close relay outputs immediately, if 2# closing input is active, its indicator lights, and the 2# source connect to load.
3. Press, 1# or 2# open relay outputs immediately, if 1# or 2# closing input is inactive, the indicators is black, the 1# or 2# power disconnect with load.

Remark: For the ATS of no OFF position, pressing key is invalid.
13.2 AUTOMATIC OPERATION
Press and the automatic LED will light. Controller enters AUTO mode and can automatically switch load to 1# or 2#.

13.3 ATS POWER SUPPLY
The power of ATS is smartly controlled by controller. As long as one power is normal, it can ensure ATS voltage power supply normally and can be transferred properly.
Users should select power supply voltage (phase voltage or line voltage) based on ATS type. If phasevoltage is chosen, connect the phase voltages (e.g. A phase) of #1 and #2 separately to N/C Pin 5 and N/O Pin 7 of auxiliary output 1; and connect N phases of #1 and #2 separately to N/C Pin8 and N/O Pin10 of auxiliary output 2. And then connect the common output of auxiliary output1&2 to ATS power supply. Power on the controller, and enter the parameters set page. Set aux. output 1 to “ATS power L1” and set output 2 to “ATS power N”. If the ATS power is supplied by Line Voltage, setting way is the same as above, and it only needs to change phase N to phase voltage. Aux. output 2 also needs to be changed based on the settings. Wiring diagrams are shown as below:

Note: Normally Close (NC) input voltage must come from 1# voltage.

FAULT FINDING

Table 13 Fault Finding

Fault Symptom	Possible Remedy
Controller no operation	Check battery voltage Check DC fuse.
RS485 communication failure	Check whether RS485 negative and positive are right connected. Check whether RS485 converter is abnormal. Check whether module address in the parameter settings is correct. If the above methods are not available, try to short connect GND of controller with RS485 converter GND (or PC GND). It is recommended that a 120Ω resistor is added between A and B of RS485.
Programmable    output error	Check programmable output connections, and pay attention to N/O and N/C. Check output settings in parameters settings.
Programmable      input abnormal	Check whether the programmable input is connected to GND reliably when it’s active, and hung it up when it is inactive. (Note: The input will be possibly destroyed when connected with voltage)
ATS is not work while Generator running	Check ATS. Check the connection wirings between the controller and the ATS. Check whether breaking positions of  ATS are in accordance with the set breakings.
