Relay Assignment
4.6.1 Principle of Operation
RELAY PANELS
External relay panels can be connected to the controller. In all, the controller can
monitor up to 64 external On/Off relays and 2 variable outputs. Refer to the wiring
diagram enclosed with this manual to connect the relay panels to the controller.
Templates are available at the end of this manual to
help with the relays’ assignment.
TUNNEL CURTAIN RELAYS
Relays 13-14, 15-16, 29-30 and 31-32 of the relay panels have specially been de-
signed to open/close the tunnel curtain. It is strongly recommend to use these relays
for this specific purpose: this prevents activating both the OPEN and CLOSE relays,
by inadvertence, at the same time.
TIMER RELAYS ON FAN STAGES
Fan stages can activate relays that operate following a timer. This is useful to activate
a mist unit that follows the ventilation’s progression. Select “TMR” on a fan stage
relay to activate this function.
THE RELAY ASSIGNMENT MUST BE
DONE SEPARATELY FOR EACH PROGRAM
THAT IS USED BY THE CONTROLLER.
