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
