Automatic test following E DIN EN 63027
In the background an automatic test for the unit is performed about every 24h.
A pseudo-arc is generated in the toroid coil and processed by the circuitry. If there is
no fault in the circuitry, an alarm (red LED)will not be generated and the test remains
undetected. In case of a fault, the LED (Image 1: Pos. 4) shines red , the plug socket
(Image 1, Pos 2) is no longer energized and the mains control lamp is off . If a reset or
calibration (see chapter 5. and 6. ) are not successful, the unit needs to be returned
to the manufacturer.
5.
Reset
By pressing the green push-button „Reset“(Image 1, Pos. 7) for 2 seconds after the
LED went red because of an arc detection, the red LED will shine green again if there
is no other fault in the circuitry. Pushing the red and green push-buttons (Image 1,
Pos. 6+7 ) simultaneously for 2-4 seconds a calibration is performed (see chapter 6.)
6.
Calibration
If there is a disturbance on the cable to be monitored and the red LED is on (Image 1,
Pos. 4) and if the red LED will not shine green after reset (see chapter 5.), there will
be a fault in the sensor´s circuitry or the voltage created by the disturbance is outside
the calibration range. In this case you press simultaneously the “Test” push-button
(Image 1, Pos.6) and the “Reset” push-button (Image 1, Pos. 7) for 2-4 seconds. The
circuitry automatically adjusts itself to the new voltage. After that, a self-test is
performed. If this test is positive, the green LED will be on again as well as the mains
control lamp (Image 1, Pos. 1). Calibration can be performed at any time during
normal operation. If the LED stays red after calibration, please pull the cable to be
monitored out of the toroid coil and retry a calibration. If the LED goes green, the
adapter cannot adjust itself to the specific disturbance on the cable to be monitored,
arc detection will not be possible any more. If the LED stays red without the cable to
be monitored, unplug the adapter from mains, unplug any switch-off unit from the
plug-socket (Image 1, Pos. 2 ) and return the adapter to the manufacturer.

Cover Caps (Image 1, Pos. 3)
There are two black cover caps on the surface of the adapter´s housing.
Only the
manufacturer is allowed to remove these caps.
