9 Reset Key
To cancel or return to the previous status during Parameter setting, use the Magnet-Bar and
touch once.
(Each touch returns to the previous status by one unit.)
10 ↑(UP) Key
During conversion of mode or number, use the Magnet-Bar and touch once. Each touch converts
or increases displayed value by one unit.
11 ↓(DOWN) Key
During conversion of mode or number, use the Magnet-Bar and touch once. Each touch converts
or increases displayed value by one unit.
12 External Earth Ground
It must be grounded to ourside of detector for protection from external noise or strong electric
field.
Use a conductor that is 4 mm or longer when coupling ground line.
13 Mount Hole Hole to fix the gas detector on external wall or other installation sites.
14 Sensor
It is a site that detects actual gas leak. It converts the amount of gas leak into electrical signal and
transmits to the Main PCB.
15 Conduit Connection
It is supplied for inlet of power supply and measurement output signal for the detector during
installation. For cable inlet, PF or NPT 3/4", 1/2" are prepared.
16 Internal Ground
It must be grounded to inside of detector for protection from external noise or strong electric
field.
Use a conductor that is 4 mm or longer when coupling ground line.
17 FRONT CASE
It is an explosion-proof case made of explosion-proof plastic and emits LED light externally
through transparent window.
18 CASE RING It serves as a cover to prevent deviation of front case.
19 SEXANGLE BOLT It serves to prevent deviation after case ring assembly and is fixed by mood bolt.
20 CASE BODY It is the main body that protects internal buzzer and other parts by body.
21 BUZZER It receives signal upon an event of error and generates warning sound.
22 FIXED RING It prevents deviation of sinter filter upon external shock.
23 FLAME ARRESTER
It blocks flow in of dust, debris, water, gas and delivers warning sound from the buzzer to
outside.
24 ARREST CAP It protects sinter filter from external shock.
25 LED COVER It is a joint for LED PCB ASS'Y and covered with moulding.
26 LED PCB ASS’Y It is a multi-color LED that displays status.
27 NUT It serves to fix parts to the compliment part.
28 SHAFT BODY It serves to fix parts to the opponent.
29 CABLE WIRE It supplies power and transmits data.
