ANALOG AND DIGITAL CONTROLLER

Revision D.0
Rep. Function
Fault and Alarms relays (2 relays are located under the power supply; tag I). From
top to bottom:
• Fault (Fault relay, non-configurable)
• R1, R2, R3, R4 (alarm relays, configurable)
Configuration of Alarm Relays
Alarm relays are to be programmed with
COM 32
software. The PCB printing displays while unpowered. R1 to R4 relays
configured as normally energized
(the coil is powered when not in alarm) or
normally de-energized (the coil is powered when in alarm). There are different way
to program the relays:
• Normal mode: relay operates as the alarm sequence. The sure can set a delay
and chose the relay to be latched or unlatched (see Alarm Acknowledgement,
page 18).
• Buzzer mode: This mode is usually used for audible alarms management. The
‘buzzer’ relay acts as a ‘normal’ relay but can be acknowledged even if the
alarm is still present (in order to turn the siren off).
The time delays are:
. Reset Inhibit: Minimum time of activation, adjustable from 0 to 900 seconds.
. Automatic reset: Time adjustable between 15 and 900 seconds, beyond which
the buzzer relay is automatically deactivated.
. Reactivation time: Time adjustable between 15 and 900 seconds, beyond which
the buzzer relay is automatically reactivated if the alarm is still present.
by the logic operators OR, AND, NOR, NAND. Up to 4
levels of parentheses. The result of the equation controls the relay.
• Voting operation (x out of y): There must be at least “x” events out of “y” to
activate the relay. Depending on user’s programmation, a FAUT event can be
treated as an alarm event.
S. Relays status DEL indicator. Illuminated when the corresponding relay coil is ON.
T. 4 Amp fuse, protects the 24V power supply input
U. Modbus RS485 communication board (option, see page 69)
Zero setting potentiometer (on the left line #1, on the right line #2)
Span setting potentiometer (on the left line #1, on the right line #2)
Catalytic bead current adjustment (top line #1, bottom line #2). Settings are
reserved to authorized personel
Y. Faut relay terminal. DPCO relay, 250Vac-30Vdc / 5A
