Problem

Solution

The power supply

indicator (L1, L2 &

L3 LED) are off.

Is there power

connected to the

meter?

Are L1, L2, L3 and N

connected

correctly?

Maybe there is a

fault inside the

meter.

Check the fuses and surge

protection.

Make sure the wires are

connected properly and tighten

the screws if possible.

There should be 230V AC between

the N and one of the L connections

and 400V AC between the L

connections when power is

supplied to the meter.

Please contact technical support

for a meter replacement.

The consumption

LED is not flashing

(PULSE LED).

Is there any load

connected to the

meter?

Is the load on the

line very low?

Maybe there is a

fault inside the

meter.

Only if there is a load on the meter

this LED will flash.

If the load is very low, the time

between 2 flashes is very long.

This can be mistaken for a broken

meter. As a test, an electric water

boiler (~1600W) should make it

blink once every 15 seconds.

Please contact technical support

for a meter replacement.

The register doesn’t

count.

Is there almost no

load on the meter?

Maybe there is a

fault inside the

meter.

Check if the consumption led is

blinking (see above). 16 flashes of

the LED equals 0.1kWh and

should be clearly visible on the

display.

Please contact technical support

for a meter replacement.

No pulse output.

Is DC power

connected to the

meter ?

Is the pulse output

connected

correctly?

Maybe there is a

fault inside the

meter.

Check the external voltage source

(Ui) is 5-27V DC.

Check correct connection:

connect 5-27V DC to connection 6

(anode), and the signal wire (S)

to connection 5(cathode).

Please contact technical support

for a meter replacement.

Pulse output rate

wrong.

Maybe there is a

fault inside the

meter.

Please contact technical support

for a meter replacement.
