Debugging and Operation
●Check whether the technical parameters of product comply with the operation requirements;
●Please separate the resistance wires between the phases after installation;
●The inlet line and outlet line of contractor must be connected firmly to prevent burns to the terminals and
products due to terminal block overheating caused by loose connection;
●The insulation resistance of the electrical appliance selected for the discharge device in the power factor
compensation equipment shall be greater than √2Ue;
●Power on the control circuit and conduct the no-load operation test, and then connect the load after no
abnormality is found during test;
●Prevent foreign matters falling into the product;
●It is recommended to select SCPD according to type 1 coordinated protection; the model of fuse is shown in

Maintenance and Service
●Tighten the terminal blocks of contractor firmly on a regular basis, and remove the deposited dust, otherwise the
risk of fire or short circuit may occur;
● Small metal particles sprayed around the contactor or on the arc hood should be removed, and the contactor
shall stop when the contact surface is burnt until the base material is exposed.
Fault Analysis and Solution
The common fault analysis and solution see Table 6.

Table 6 Common fault analysis and solution
Fault
Cause
Solution
The iron core cannot
be pulled in or the
suciton force is
insufficient (that is,
the contact is closed
but the iron core is
not completed pulled
in)
1. The power supply voltage is too low or
fluctuates too much;
2. The power capacity of the operating circuit is
insufficient or the wire is broken, wiring is
incorrect and the control contact has poor contact;
3. The technical parameters of coil are inconsistent
with the working conditions;
4. The product itself is damaged (such as coil
broken or burnt, and mechanical movable part
blocked).
1. Incease the power voltage;
2. Increase the power capacity;
replace the line; repair the control
contact;
3. Replace the contactor;
4. Eliminate the blockage fault, and
replace the contactor.
No release or slow
release
1. Contact fusion welding;
2. The mechanical movable part is blocked;
3. There is oil strin or dust sticking to the pole face
of the iron core.
1. Eliminate the fuse welding fault,
and repair or replace contactor;
2. Eliminate the blockage fault;
3. Clean the pole face of the iron
core.
Coils are overheated
or burnt
1. The power voltage is too high or too low;
2. The technical parameters (such as rated voltage,
frequency, on-load factore and applicable working
system) of the coil are inconsistent with the actual
operation;
3. The moving part is blocked;
4. The pole face of iron core is unfatted or stuck
with dust.
1. Adjust the power voltage;
2. Replace the contactor;
3. Eliminate the mechancial
blockage fault;
4. Clean the pole face.
Large noise issued
from the
electromagnets (AC)
1. The power voltage is too low;
2. The magnetic system is skewed or mechanically
blocked, making that the iron core cannot be pulled
in flattly;
3. The pole face of iron core is rusted or intruded
by foreign matter;
4. The short-circuit ring is broken or the pole face
of iron core is worn excessively and uneven.
1. Increase the operating loop
voltage;
2. Adjust the magnetic system or
eliminate the mechanical blockage
fault;
3. Clean the pole face;
4. Replace the contactor.
Contact fusion
welding
1. The operating frequency is too high or the
product is overloaded;
2. Short circuit at the load side;
1. Replaced by an appropriate
contactor:
2. Eliminate short circuit fault.
Resistance wire burnt
The resistance will be burnt if the closing current is
too large beyond the suppression capacity of this
switching capacitor contactor when the contactor is
closed.
Replaced by an appropriate
contactor
