6 holes each of Ø16.5 and Ø 20.5 are set at the bottom part. Depending on the site condition,
power cable, signal cable, etc. are connected using cable inlet.
6 O - Ring <NBR> It works as waterproofing material to prevent rainwater from entering inside.
7 Power LED When power is inputted, the power LED lights on.
8 Stand-by LED When the detector is in stand-by mode, STD-BY LED blinks.
9
Fault LED
(Trouble LED)
Upon an event of trouble in receiver unit and detector part, the trouble LED lights on.
Ex.) * Poor wiring with the detector and an event of error
10 Alarm 3 LED
When the tertiary alarm occurs, Alarm 3 LED lights on.
When it reaches Alarm 3 threshold during a test, Alarm 3 LED lights on.
11 Alarm 2 LED
When the secondary alarm occurs, Alarm 2 LED lights on.
When it reaches Alarm 2 threshold during a test, Alarm 2 LED lights on.
12 Alarm 1 LED
When the primary alarm occurs, Alarm 1 LED lights on.
When it reaches Alarm 1 threshold during a test, Alarm 1 LED lights on.
13 "FUNC" S/W
"FUNC" S/W is a key to change and select then enter data for alarm threshold, alarm type, alarm
dead band, and alarm dwell time settings, etc.
14 "UP" S/W
After selecting each mode using "FUNC" S/W, use to increase the set value or to select the next
setting.
When a value needs to be changes in a large range, pressing "UP" S/W for a certain time changes
the value rapidly.
15 "DOWN" S/W
After selecting each mode using "FUNC" S/W, use to decrease the set value or to select the
previous setting.
When a value needs to be changes in a large range, pressing "DOWN" S/W for a certain time
changes the value rapidly.
16 "TEST" S/W
Pressing "TEST" S/W enters a mode that performs self-test.
Measurement FND flickers and the value can be adjusted using "UP" S/W and "DOWN" S/W to
check the alarm operation status.
To release self-test, press "RESET" S/W.
17 "RESET" S/W Performs functions to release alarm, self-test, and program setting, etc.
18 "BZ-STOP" S/W Used to stop the buzzer upon an event of alarm
19 Buzzer Operates in a continuous tone upon an event of warning or fault during a test.
20 LCD PCB Ass'y
Displays measurement from detector in a continuous manner.
During test, it displays user defined value with flickering.
21 Terminal Block Cover To supply power to the equipment, open the terminal block cover and connect power cable.
