Connection/set up
The transducer is equipped with a red LED for indication of wrong phase connection
or errors in the calibration / configuration. This LED is placed under the front plate.
The function of the LED are as follows:
Constant light. The wiring may be wrong. There is not equal power direction on all
phases. There must be signal on all inputs to ensure correct testing and current flow
in all phases. Note this function is only activated in coupling 2W3, 2var3 and 3W3(4),
3var3(4).
Fast pulse 5Hz. The calibration data are corrupted. Contact DEIF.
Slow pulse 1Hz. The configuration data are wrong or corrupted. Make a re-
configuration or contact DEIF. About configuration see special manual.
