4.7. Relay Assignment
4.7.1. Principle of Operation
Relay Panels :
The controller can activate up
to 64 On/Off relays; these relays are located
in external relay boxes. Up to two RP-32 relay
panels can be connected to the controller. Refer
to the wiring diagram enclosed with this manual
to connect relay panels to the controller.
Vent Door & Tunnel Curtain Relays :
Relays
13-14, 15-16, 29-30 and 31-32 the relay
panels have specially been designed to open/
close the vent doors and the tunnel curtain.
It is strongly recommend using these relays
for this specific purpose: this prevents acti-
vating both the OPEN and CLOSE relays, by
inadvertence, at the same time.
Fan & Tunnel Fan Relays :
• Timer-based relays:
Fan groups and tunnel
fan groups can activate relays that operate
in timer mode. These relays allow activating
cooling devices such as mist units while a
specific fan/tunnel fan group is running. Se-
lect “TMR” on a relay to use this function.
• Open/close relays:
Relays can be used to
slightly open an air inlet at the start-up of a
fan/tunnel group and to close it when the
fan/tunnel fan group returns to a stop. The
inlet opens only once at the start-up of the
chosen fan/tunnel fan group and closes only
once when the group is disabled. The inlet’s
running time corresponds to the timer-based
relay’s On Time. Select
“OPN”
to assign an
opening relay or
“CLO”
to assign a closing
relay on a fan/tunnel fan group.

Fan Group 1 Relay Assignment
Selected output
This relay will run in timer
mode when fan group 1
is active
This relay will
runs when
fan group 1 is
active
This relay switches at the
startup of fan group 1. The
inlet opens once, during
the timer-based relays’
On time.
The relay switches when
fan group 1 returns to a stop.
The inlet closes once, during
the timer-based relays’
On time.
Relays 13-16 and 29-32 of the relay
panels have been designed to open
and close actuators (vent doors or
tunnel curtains).
