Commissioning
•
Power the device: LINE LED lights and FAULT LED and ALARM LED flash.
•
After
1.5…2
minutes the detector is enabled to acquire alarms and the LEDs FAULT and ALARM should go out.
•
Position the SENSITIVITY knob on "0".
•
Since the sensors are selective, and so not influenced by gases other than that for which they are dedicated, to simulate the presence
of gas it is necessary to use small gas cylinders containing specific gases at preset concentrations, releasing the gas as near as possi-
ble to the detecting sensor. Only for sensors for detecting propane (LPG) can gas from a normal cigarette lighter be used.
•
When the gas concentration exceeds the pre
-
alarm threshold the ALARM LED flashes.
•
With a delay (about 20 seconds) after exceeding the alarm threshold:
—
ALARM LED lights and stays lit.
—
The internal alarm and the outside warnings (only if without jumper M
-
F1) are switched on.
—
The operational relay closes the gas shut
-
off valve or switches on the aeration fan.
•
Stop erogation of gas. When gas concentration on the sensor returns below the threshold level:
If detector is
“
without latching
”
(with jumper between F3
-
F4), alarm ceases and ALARM LED remains flashing slowly until RESET button
is pushed
If detector is
“
with latching
”
(without jumper between F3
-
F4), alarm remains until RESET button is pressed for at least 5 seconds.
•
If the detector controls a valve with manual reset, it is necessary to re
-
open manually also the valve.
