5.1 Power / fault indicator LED
LED colour LED constant
LED Flashing (1 Hz)
All OK (ASB OFF)
DIP switch changed, but
product not reset
Low signal indication
-
Channel crosstalk
-
ASB ON indication
-
Explanation:
1. Green LED (steady): Unit is powered up and everything is working well.
2. Green LED (blinking): Dip switch has been changed since last power up and Loop Detector has not
been reset yet. Please press the reset button.
3. Yellow LED (steady): Signal level is low in the loop.
4. Red LED (steady): Crosstalk of loop frequency with another loop detected. Select different frequency
channel on DIP switches and reset product.
5. Blue LED (steady): Automatic Sensitivity Boost is turned ON and everything is working well
5.2 Loop state LED
Explanation:
1. Green LED (steady): Loop inductance is within limit and working well
2. Yellow LED (steady): Loop inductance is too high (more than working range 1000µH)
3. Yellow LED (blinking): Loop inductance is too low (less than working range 20µH)
4. Red LED (steady): Loop is open circuit
5. Red LED (blinking): Loop is short circuit
LED colour LED constant
LED Flashing (3 Hz)

5.3 Relay state LED
Explanation:
1. Yellow LED (off): Relay is not activated
2. Yellow LED (steady): Relay is activated and in presence mode
3. Yellow LED (Flashing 0.5 s): Relay is activated and in pulse mode, 0.1 s
4. Yellow LED (Flashing 1.0 s): Relay is activated and in pulse mode, 0.5 s
