Motor current alarm
Thread Content
We use a central DCS system; there is a motor in the workshop, and a high-current alarm has been set up as per requirements. This motor is used intermittently, and an current alarm occurs when it starts up, but normal operation is restored after a few seconds. Is there any way to silence this useless alarm?
I personally think it’s not easy to handle. If you try to use a delay function, then when the police do arrive, the alerts will be blocked for some time, which actually creates problems. If it is started directly, a high starting current is normal, and alarms are also normal.
Consider the plan for the 2nd floor, taking into account the concerns regarding the 3rd floor. Add the start DO (if any) to the delay logic. If there is no DO, use DI instead. It is possible to determine whether it is a current alarm that has just started or one that has been active all along.
Thank you. I hadn’t come across this before. Today I asked our instrumentation engineer to add a 10–15 second delay, and he said that it’s not possible to set up a delay alarm within the channel; it would need to be achieved by writing code. He also mentioned that if writing a program affects the alarm parameters within the channel, he doesn’t know what to do now.
The motor should have a protector in the distribution room that allows the starting current limit to be increased. However, it is necessary to investigate the cause, check the motor’s factory specifications, or consult the motor manufacturer to find out the maximum adjustment level possible.
Regarding startup, a few words about small programs white..... When writing programs, how can it \"affect the alarm parameters within the channel\"? It won’t drip......
