Only if necessary, for maintenance or installation requirements, the housing cover can be separated from its base,
first remove power supply, then disconnect the flat cable, press on the two side tabs as shown
it, push the flat cable into the connector, respecting the polarization, the two levers close automatically locking it.
Only then you can reconnect power supply.
Cable glands: the lower side of the housing has 3 inputs designed for metric cable glands (M20x1.5 that accept
external cables Ø 6÷12 mm). These passages are closed, but they are not

Electrical Connection:
the gas detection system. The device, clearly identified, must act only on Phase and Neutral. If it is necessary, you
may install a surge or lightning protector, etc.
The instrument is supply with non-reversible and plug-in terminals. Therefore the cables should be anchored to the
case in order to avoid terminal overstress. The connection to the control unit does not need any hearting. The remote
sensor can be placed at a max. distance of 100 meters from the control unit with a cable of 3x1.5mm
of 200 meters using a 3x2.5 mm

control unit functioning).
ON = Enabled input The detector is installed, the Led Bar and the Fault Relays and Miscel-
laneous are in operation. (
OFF = Input DISABLE The detector is absent, the Led Bar is off. Fault relays and alarms do
not intervene. (can also be used to exclude a faulty detector or removed for maintenance).
SET AUX: SW2 Dip-Switch No.1 selects AUX input
OFF = contact lenses for eg contact. Manual button (DEFAULT SETTING)
ON = control of NC Valve Solenoid Valve with Location Sensor.
In Fig. 7 Schematic and Configuration of SW2 Dip-Switch No.1 to use the AUX input to check if the Valve has
actually been closed. Valves need to be reassembled with NC Position Sensor.
In Figure 8 Connection Schedule and Configuration of SW2 Dip-Switch No.1 to use the AUX input, placed on the
board in the cover with a NA contact. For example, a manual alarm button.
Thresholds: the SW2 Dip-Switches / No.2 and No.3 set the alarm thresholds. See Table 2.
Relay
No.2 and No.3 both OFF = ALARM 1 set to 10%LEL and ALARM 2 set to 20%LEL (DEFAULT SETTING)
No.2 ON and No.3 OFF = ALARM 1 set to 15%LEL and ALARM 2 set to 20%LEL
SW2 Dip-Switch No.4 sets the function of the ALARM 2 relay.
Logic of Relay:
ON = Negative logic, the relay is de-energized, it is used for normally open valves.
OFF = Positive logic, the relay is normally energized, in case of power failure or relay failure, it auto-
matically moves to the alarm position. It is used for normally closed valves.

WARNING

Configure Dip-Switches before powering the control panel.
The detector doesn't need adjustments after being installed.
During preheating of the detectors, which is of about 60 seconds, the alarm relays remain inhibited, while the
