Why is the air exhaust temperature too high in my SCC MAM – 890 Controller?
If the air exhaust temperature of your SCC Controller is too high, it could be due to a bad vent condition or insufficient lubricant. Check the vent condition and the amount of lubricant.
What to do if the pressure is too high in my SCC Controller?
If the pressure in your SCC Controller is too high, it's likely due to over pressure. Inspect the pressure and the pressure sensor to resolve this issue.
What causes overload during start in SCC MAM – 890 Controller?
If your SCC Controller experiences overload or rotor locking during startup, it's probably because the time set is less than the star delta delay starting process. Reset the host starting time to be longer than the star delta delay starting time plus the load delay time.
What to do if SCC MAM – 890 Controller shows wrong cable connection?
If you have the wrong cable connection or a wrong set in your SCC Controller, it may be caused by a short circuit. Verify the wiring and set the data correctly.
Why main contactor activate time to in SCC Controller?
If there are issues with the main contactor activation time in your SCC Controller, the emergency button may be loose. Check the wiring.
