Fault detection method 1
1. You can check whether the voltage of the Omron relay is high or low, generally the maximum is between 180V-240V, if the excess value deviation is too large, it is possible that the Omron relay has been damaged.
Fault detection method 2
2. In addition, when the Omron relay fails, the first thing to check is the external wiring of the relay to see if the wiring of each contact of the relay is wrong, or the wire is broken, falling off or other abnormal phenomena.
Fault detection method 3
3. The second is to check the power supply circuit of the Omron relay, and use the meter to test whether the voltage of the positive and negative power supply is the same, if the voltage value is the same, it can be inferred that the relay is normal. If there is no problem with the voltage, the power amplifier delay and protection circuit can be carried out later.
Fault detection method 4
4. At this time, the Omron relay still needs to measure the final circuit of the power amplifier, and you can visually check to see if there are any components burned, and pay attention to the burnt is not necessarily bad. It needs to be further measured, whether the emitting stage resistance of the power amplifier tube has DC voltage to the ground (the normal value is within 0.7V), if there is DC voltage, it is generally the problem of the final circuit of the power amplifier, so the treatment method can only replace the emission stage resistance of a power amplifier tube.
Omron relay note instructions
1. When installing the Omron relay, it must not be pushed too hard, so as not to damage the shaft system and the code disc. The OMRON relay should be gently pushed into the duvet shaft.
2. When using Omron relays, it is necessary to always check whether the leaf springs are loose relative to the Omron relays, and whether the screws of the relay are loose, so as to avoid some accidents such as failures in the process of operation.
3. Do not connect the terminals between Omron relays indiscriminately, otherwise it is easy to cause damage to Omron relays during power-on operation.
