Problem Mögliche Ursache Überprüfung / Lösung
The red consumption LED is not flashing
(PULSE LED). There is no load connected to the
meter. The load on the line is very low. Connect a load to the meter. Check with
an Ohm-meter if the load value is very
low.
The register doesn’t count. There is almost no load connected to the
meter. Check if the red consumption LED is
flashing.
No pulse output. The pulse output is not supplied with DC
power. The pulse output is not connected
correctly. Check the external voltage source (Ui) is
5-27V DC with a voltage meter. Check if
the connection is correct: the 5-27V DC
should be connected to the collector
connection (pin 4/6) and the signal wire
to the emitter connection (pin 5).
