Problems after a power outage of the device
Thread Content
The device lost power for a few minutes before the power came back. At that time, the motor control panel was activated – but did the motor have power at that point? Would the motor start running? If the device loses power temporarily and then gets power back immediately, is it the start motor control lever that’s to blame? When the motor has power, it can operate. Please, experts, tell me. Thank you
Depending on the size of the motor, large motors are designed not to allow continuous starting.
Power outages and voltage fluctuations are two different things. During a power outage, all electrical devices stop working; when power is restored, it is necessary to follow the emergency shutdown procedures outlined in the manual, and it’s essential to consult with the dispatch team during this time. Voltage fluctuations cause unstable power levels, which can result in some devices shutting down temporarily. In my experience, I usually just restart the devices immediately, but for some devices, it’s necessary to handle the situation accordingly
Fluctuating power supply: In the PLC programs of some large motors, a delay is programmed before starting up
Everyone who has been on the scene knows this. It depends on the design features of the device; sometimes the motor won’t stop in case of voltage fluctuations. In the event of a power outage, whether the motor can be started depends on how the interlocks are set up – if there are no interlocks, then it can be started using the on-site button.
In the case of voltage fluctuations, it depends on whether you have a voltage protection device or an inductive current protection device; if not, the motor generally won’t stop operating, but this can still cause significant damage to the motor!
It depends on the situation; flexible operation is required. In the event of power fluctuations, some motors have self-protection features, so it may be necessary to press the reset button first and then start the motor for power to be supplied
It depends on the power of the motor; motors that start under high voltage are not possible.
