Controller no operation Check the Phase A1, N1 or Phase A1, N1 voltage.
Check connection wirings from the controller to ATS.
Check DC fuse.
Rs485 communication failure Check whether the RS485 is wrong connection between negative and positive.
Check whether the RS485 adapt is abnormal.
Check whether the parameter settings in the module addresses are incorrect.
If the above methods are no using, you can try to connect the GND of controller with RS485 GND (or PC GND).
Recommend that the A and B lines of the 485 network should be terminated at each end with a 120Ω resistor.
Programmable output error Check programmable output connections, pay attention toNormally opened and closed.
Check the output parameters settings.
Programmable input abnormal Ensure that the programmable input connect to GND reliably when it's active, and hung up when it is inactive.(Note: The input will be possibly destroyed when connected with voltage)

the screen will show as following:

Press  key to select corresponding function, and press  key to confirm.

 

 

COMMISSIONING
 

STOP TO TEST: This will stop a start generator signal immediately.

 

TEST OFF-LOAD: This will send out a start generator signal immediately. After 2# source is normal, if 1# source is normal, the ATS will not act. The ATS will transfer the load to 2# only when 1# source is abnormal. After 1# source return normal, the ATS will transfer the load to 1#. Here the start generator signal output will keep.

 

TEST ON-LOAD: This will send out a start generator signal immediately. After 2# source is normal, the ATS will transfer the load to 2# source immediately regardless of 1# source normal whether or not.

 

CYCLE START: When choosing this mode, generator start-signal will cyclic output according to mains status, user can set the cyclic time. If generator fault of input-signal, no longer send start- signal. If in manual mode, will keep the current status and cancel cycle start.

 

Conditions under this mode:

1.In automatic mode.

2.Output port setting: 1# engine start output (Normal Output) and 2 # engine start output (Normal Output).

3.Input port setting: 1# generator fault input and 2# generator fault input.

4.Must set the and the .

5.The system type set must as 1# Gens & 2# Gens. 6.Set the right .

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

 

 

PARAMETERS CONFIGURATION

 

In the main interface, press  key, choose 1.Parameters setting and then press  key, to enter interface of confirming password.
