3.7 Outputs
Use a separate cable to connect each output. It is recommended to use 2
−core shielded cables, not multicore
cables.
If a shielded cable is used, the cable’s shield must be connected only to the earth bar terminal inside
the panel.
The outputs of the panel are (as labeled on the PCB):
•
OUT1 & OUT2:
Two programmable resistance-controlled outputs.
•
24VM
: One 24 V
DC
(300mΑ max.) voltage output, used to power devices that must be interrupted via
panel’s reset. Output is disabled for about 10 seconds after the reset.
•
24VP
: One 24 V
DC
(300mΑ max.) voltage output, used to power devices that must
not
be interrupted
via
panel’s reset.
The programmable output terminal connections come preinstalled with a 10kΩ resistor, between
OUTx
and its
corresponding negative terminal (marked
(
–)
on the board). This is done for continuous line monitoring and
detection of open and short circuit line problems. If a programmable output is unused, the resistor must
remain connected to the corresponding terminals.
Programmable output activation can be triggered by one of these actions:

TRIGGER ACTION
DESCRIPTION
IN EMERGENCY
Triggered when one or more points are in emergency mode.
IN FAULT
Triggered when there are one or more faults.
ON TEST
Triggered when one or more points are in test.
IN INHIBIT MODE
Triggered when one or more points are in
inhibit mode
.
