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
The transfer switch is immediately driven in 0 position (only in contactor mode).
Keypad action (Validation) necessary to Reset the fault
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 (1 s front).
The Mtf variable in the setup menu must be selected (Yes) to allow input recognition
S2A Information source 2 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 (1 s 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
