Removal of errors

Description of the error
No indication.
Current
too little / too high.
Voltage
L2-L3 too little / too high.
Real power
too little / too high.
Real power supply/con-
sumption exchanged.
Cos(phi) = 0.00
Cos(phi)
too high / too little.
Cos(phi) does not change,
although all capacitor
stages were switched in.
Cos(phi) is indicated ca-
pacitive on Prophi, but,
nevertheless, the reactive
power meter measures re-
active power.
Prophi only connects
stages, but does not dis-
connect.
The outputs can only be
disconnected.
Prophi shows a cos(phi) of
0,2 - 0,4 capacitive.
It does not work.
= Key 1
Possible cause
- Wrong measurement and supply voltage
connected.
- Prefuse (10A time-lag type) has triggered.
- Current measurement in the wrong outer
conductor.
- Wrong current transformer ratio.
- Current out of measuring range.
- Current transformer clamps are bridged.
- One current transformer line is interrupted.
- A current measuring device is connected
parallely.
- Wrong voltage transformer ratio.
- Uneven load of the outer conductors.
- Wrong voltage transformer ratio.
- Voltage and/or current are measured incor-
rectly.
- Voltage and current are measured in the
wrong outer conductors.
- Voltage and/or current are measured incor-
rectly.
- The current transformer connection (k-l) is
exchanged.
The measuring current is smaller but 10mA.
The measuring voltage is interrupted.
The current transformer clamps are bridged.
- Voltage is measured incorrectly.
- Current is measured incorrectly.
- Real power is measured incorrectly.
The current transformer is installed after the
measurement of the energy supplier.
Current and voltage are connected in-cor-
rectly.
The capacitor current is not detected by the
current transformer.
Capacitive stages are faulty.
The measurement and operating voltage is
exceeded by more than 10%.
Current measurement in wrong phase.
L1 and L3 are exchanged.
The device is defective.
= Key 2 = Key 3
Remedy
Please check measurement and sup-
ply voltage.
Please check current measurement.
Please check voltage measurement.
Please check current and voltage
measurement.
Please check current and voltage
measurement.
Please check current measurement.
Please check current and voltage
measurement.
Check and correct connection.
(Please see hints for installation)
Check and correct connection.
(Please see hints for installation)
Check and correct mounting posi-
tion of the current transformer.
Check capacitive stages.
Check measurement and operating
voltage.
Check measurement and operating
voltage.
Send the device to the manufacturer
with an exact description of the error.
