Function No Function* Input disabled
Emergency Stop Transfers to O position in delayed transition I-O-II type
switches. Disables automatic control mode in both
delayed and open transition types.
Remote Test on Load Start/stop test on load sequence in rising (NO) or falling
(NC) edge of the input signal.
Remote Test off Load Start/stop test off load sequence in rising (NO) or falling
(NC) edge of the input signal.
Inhibit ATS Prevent switch control operations, configuration, test
sequences and generator start in case of priority source
failure.
Manual Retransfer Disables automatic transfer back to priority source.
Source Priority S1 Sets priority for source 1 in transformer-transformer
application.
Source Priority S2 Sets priority for source 2 in transformer-transformer
application.
Inhibit Transfer Disables automatic transfer from priority source to non-
priority source.
When input is activated, transfer to non-priority can be
initiated by pressing HMI control button and entering
the device password.
Bypass Running Time
Delays Bypass any currently running time delay.
Remote Control to S1 Transfer to S1 when active. Overridden by activated
'Remote Control to OFF' signal.
Remote Control to OFF Transfer to position O when active.
Remote Control to S2 Transfer to S2 when active. Overridden by activated
'Remote Control to OFF' or 'Remote Control to S1'
signals.
Reset Alarm Reset any active switch control alarms (open I failure,
close I failure, open II failure, close II failure).
Inhibit Transfer w/
Override Prevents ATS to transfer away from acceptable power
source. If connected power source fails ATS can transfer
to another source if it is OK.
Load Shed Input Signal Allows generator to signal to ATS to transfer away from
the generator source to prevent overload. Input works
differently with OXA_ and OXB_ switch types. OXA_
models: ATS transfers to priority source and stays there
while the input is activated. OXB_ models: Transfers
switch to O-position. If priority source restores while
the input is activated ATS will transfer to it.
Manual-Auto Mode Toggle automatic/HMI control mode, input is active only
in rising/falling edge according to contact type.
