General remarks
The adapter unit shown consists of the toroid coil sensor, available in two sizes, and a plug
housing with control lamps and control elements.
The adapter´s mains plug (Image 2, Pos. 8) will be plugged into a standard plug socket
(230VAC, 50Hz). Into the plug socket of the adapter (Image 1, Pos. 2), a mains-based switch-
off unit can be plugged in.
The cable to be monitored for arcs will be fed through the toroid coil with inner diameter of
8mm (-8) or 16mm (-16), independant of the feed through direction.
1.
Mains applied, Getting started, Status memory
After feeding the live DC cable to be monitored through the toroid coil (Image 1, Pos.
5), the adapter will be connected to mains (230VAC, 50Hz).
At first use the red LED (Image 1: Pos. 4) will be on for a short period of time (self-
test) and shows green afterwards, the unit is now ready for use. If the red LED stays
on, make a reset by pushing the green push-button (Image 1, Pos. 7) for 2 seconds. If
the LED stays red after the reset, you need to calibrate the unit following the
procedures in chapter 6. from this manual.
If there is a loss of mains power and mains comes back, the LED (Image 1, Pos. 4) will
be red for a short period of time (Mains control lamp (Image 1, Pos.1) is off) and
finally change to the status prior to mains loss (Alarm(Red) or normal
operation(Green)).
If the mains control lamp (Image 1, Pos. 1) is on, the plug socket (Image 1, Pos.2) is
energized.
2.
Duo-LED Red/Green (Image 1, Pos. 4)
This LED is green during normal operation and faultless circuitry, assuming a
calibration was performed (see chapter 6. for more details).
This LED is red if an arc is detected or the circuitry has a fault (including the toroid
coil sensor (Image 1: Pos. 5) or the calibration range has been exceeded or fallen
below.
3.
Test
The test function checks the components and finally the proper operation of the unit.
Test will be performed when pressing the red push-button “Test” (Image 1, Pos.6) for
2 seconds. During pressing, the LED (Image 1, Pos.4) stays red, when releasing the
push-button and proper operation of the circuitry, the LED shines green again.
If there is a fault during testing, the LED stays red. If you have tried out reset (see
chapter 5.) and calibration (see chapter 6.) and the LED shows still red, you need to
return the adapter to the manufacturer.
