more quickly LED flash, the more consumption there is.
Reading the meter
The PRO-1TE series energy meter is equipped with a 5+1 register. five integers are
marked with black color and one decimal is marked with red. The PRO-1TE LCD series
energy meter is equipped with 5+2 LCD display which is used as recording
consumption and can’t be reset to zero. The reading accuracy is 1/100 kWh.
Pulse output
The PRO-1TE Series DIN rail energy meter is equipped with a pulse output which is fully
separated from the inside circuit. That generates pulses in proportion to the measured
energy for accuracy testing. The pulse output is a polarity dependant, passive
transistor output requiring an external voltage source for correct operation. For this
external voltage source, the voltage (Ui) should be 5-27V DC, and the maximum input
current (Imax) is 27mA DC.
To connect the impulse output, connect 5-27V DC to
connector 20 (anode), and the signal wire (S) to connector 21 (cathode).
1.10 Troubleshooting
CAUTION
During reparation and maintenance, do not touch the meter connecting
clamps directly with your bare hands, with metal, blank wire or other
material as you will have the chance of an electricity shock and a possible
chance for health damage.
Turn off and lock out all power supplying the energy meter and the
equipment to which it is installed before opening the protection cover to
prevent the hazard of an electric shock.
WARNING
Maintenance or reparation should 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 reparation.
Case is sealed, failure to observe this instruction can result in damage for
meter.
Problem
Check
Solution
No light for the
Power supply
indicator.
Is AC power supply
connected to the
meter ?
Is the 1 and 4
connecting correct ?
Maybe there is a
fault in the inside
circuit.
Check switch or circuit-breaker
and fuse or thermal cut-off.
Reinstall terminal screws on the 1
and 4. Make sure all screws are
fixed. Than there should be a
230V 50Hz AC voltage between
the terminal screws on the 1 and
4 when power supply is input.
Please contact your technical
supporter to replace this meter.
