Inepro Metering – PRO Series 1 – 17
7 Troubleshooting
Problem Possible cause Check/Solution
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
seem to count.
There is almost no load
connected to the meter
Check if the red consumption LED is
flashing. 10.000 flashes of the LED at
100 pulses per kWh equals 0.01kWh.
No pulse output.
The pulse output is not
supplied with DC power.
The pulse output is not
connected correctly.
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 20+) and the
signal wire (S) to the emitter connection
(pin 21-).
The pulse output
rate is wrong.
Is the correct pulse rate
set via the infra red eye
and software?
Download or request the software and
use the infra red eye which can be
bought separately.
If none of the above works, please contact technical support
CAUTION
• During repair and maintenance, do not touch the meter connecting clamps directly with your
bare hands, with metal, blank wire or other conducting material as that will cause an electric
shock and possibly cause injury, serious injury or even death.
• Turn off and if possible lock all sources supplying the energy meter and the equipment that is
connected to it before opening the protection cover and working on it.
• Turn off and lock all power supply to the energy meter and the equipment to which it is installed
before opening the protection cover to prevent the hazard of electric shock.
WARNING
• Maintenance or repair should only be performed by qualified personnel familiar with applicable
codes and regulations.
• Use insulated tools to maintain or repair the meter.
• Make sure the protection cover is in place after maintenance or repair.
• The case is sealed, failure to observe this instruction can result in damage to the meter.
