）
Binary inputs

Remove external connections. Short circuit binary input terminals with test leads to
check if the space contact works well.

If it is abnormal, check if the binary input is short circuit actually. It can be measured by
meter.

Check if the power supply works well. If it is abnormal, check the external power is
normal. Then check it with kit’s DC power. If it is ok, the problem might be the external
power supply or wire connection.

If the conected protection contact is potential contact, check if there is any difference
before and after trip.

Binary output

Check if the binary output works normally without load and has contact sound.

Check if it works normally with load and exceeds binary output’s load capacity.

Open circuit current alarm
1
）
When the current distortion is about 1%, it displays open circuit. When the current output is
0 and without short circuit, the open circuit is random and doesn’t affect test.
2
）
Short circuit the current terminal, if the open circuit alarm disappears, it is external
connection problem.
3
）
All the output fuses of open circuit power supply are burnt, it casues the kit open circuit.
4
）
Check if the current output waveform is distorted or topped by oscilligram. If it is distorted, it
is overloaded. User can improve laod capacity by current series.

How to output a greater current than allowed max. single phase current?
The three-phase current power of kit can be used by parallel connection. Users need set the phase
output. It is suggested to set amplitude the same.
The total output amplitude of phase parallel connection is: I=Ia+Ib+Ic=30 + 30 + 30= 90A
