first, after open delay, then press gen
key, gen will close (directly press gen close key, no action).
The procedure of gen on-load to mains on-load is same as above.
Mains Enable:
After pressing gen
key, if gen not take load, then gen close outputs. After
pressing gen
key, if gen takes load, then gen open outputs.

AUTO TRANSFER PROCEDURE
When controller is in auto or stop mode, auto breaker transfer is active.
a)
If input port is configured as closed auxiliary input:
Mains Enable:
If open detection is enabled, mains on-load is transferred to gen on-load, after open delay, transfer
rest delay, transfer failure detection begins when open outputs; when detection time is due, if open
failure, then gen will not close, otherwise, gen will close, and transfer failure detection begins at the
same time; when detection time is due, if close failure, then wait for gen close. If transfer failure
warning is enabled, close/open failure warning will be issued. The procedure of gen on-load to
mains on-load is same as above.
If open detection is disabled, mains on-load is transferred to gen on-load, after open delay, transfer
rest delay, gen will close, transfer failure detection begins at the same time; when detection time is
due, if close failure, then wait for gen close. If transfer failure warning is enabled, warning signal
will be issued. The procedure of gen on-load to mains on-load is same as above.
Mains Disable:
If open detection is enabled, gen on-load is transferred to gen off-load, after open delay, transfer
failure detection begins when open outputs; when detection time is due, if open failure, then wait
for breaker open, otherwise, breaker open is completed. When gen off-load is transferred to gen
on-load, after close delay, transfer failure detection begins when close outputs; when detection
time is due, if close failure, then wait for closing, otherwise, breaker close is completed. If transfer
failure warning is enabled, close/open failure warning will be issued.
If open detection is disabled, gen on-load is transferred to gen off-load, after open delay, breaker
open is completed. When gen off-load is transferred to gen on-load, after close delay, transfer
failure detection begins when close outputs; when detection time is due, if close failure, then wait
for closing, otherwise, breaker close is completed. If transfer failure warning is enabled, warning
signal will be issued when closing fails.
b)
If input port is not configured as closed auxiliary input:
Mains Enable:
When mains on-load is transferred to gen on-load, after open delay, transfer rest delay, gen will
close. The procedure of gen on-load to mains on-load is same as above.
Mains Disable:
When gen off-load is transferred to gen on-load, gen close outputs; when gen on-load is
transferred to gen off-load, gen open outputs.
NOTE1:
When ATS without interposition is used, open detection should be disabled.
NOTE2:
When ATS with interposition is used, open detection can be enabled or disabled, if enabled, please configure
open output.
NOTE:
When AC contactor is used, open detection enable is recommended.
