inputs
Variable Description
Ft1 Fault input 1. the fault led is blinking as soon as the input is active and
Ft1 is displayed on LCD. Reset when the input is de-activated
Ft2 Fault input 2. the fault led is blinking as soon as the input is active and Ft2 is displayed on
LCD. Reset when the input is de-activated
Ft3 Fault input 3. the fault led is blinking as soon as the input is active and Ft3 is displayed on
LCD. the transfer switch is immediately driven in 0 position (only in contactor mode). Keypad
action (Validation) necessary to Reset the fault
Ft4 Fault input 4. the fault led is blinking as soon as the input is active and Ft4 is displayed on
LCD. the transfer switch is immediately driven in 0 position (only in contactor mode). Keypad
action (Validation) necessary to Reset the fault
Pri (1) Priority network selection.
Network 1 has priority when input is not activated. Network 2 has priority if input is active
Mtf Remote manuel re-transfer. Feature identical to manual retransfer on keypad.
Re-transfer from priority network to backup network is allowed from input activation (1s front).
the Mtf variable in the setup menu must be selected (Yes) to allow input recognition
S2A
Information source available (Genset) used instead of voltage / frequency measurement
(inhibited when S2A is selected)
Man Information transfer system in manual mode
All automatic commands (+ test on load) are inhibited as soon as the input is activated
CtS Remote transfer control. Possible to initiate transfer from priority source to backup source
before Dtt ends. If Dtt is set to its maximum value (60s), the transfer is initiated as soon as
the input is activated (1s front)
tol Remote test on load. Started from input activation.
Re-transfer is blocked until input de-activation
tfl Remote test off load
Started from input activation (remote genset start / stop)
EJP 2 inputs are automatically affected to EJP
• input 1 for EJP advice, to start generator
• input 2 to transfer on emergency source
Retransfer is activated when input 2 dissapears
(1) this information is the only considered in case of
option configuration. Programming variable Pri is then
inhibited.

LS Load shedding relay. LS timer corresponds to time available to disconnect the shed loads.
the relay is activated before permutation on standby network according to LS timer.
the relay is de-activated after retransfer on mains network and LS timer countdown
In case of LS function selection, it is required to configure associated LS timer.

• example : LS configuration (output relay Ou1, 3 seconds):
the load shedding can't be used with the priority net-
work (priority source = source ). In this case, LS
output is not valid.

the output is de-activated in case of loss of power. It may then be required to put in
parrallel with the load shedding ouptut relay, position 2 auxiliary contact. this would avoid
taking back the load in case of loss of emergency source in emergency position.
