Rotation monitor
Probable fault cause
during installation
Probable fault cause
during operation
Alarms and trips if a pulse is not received every 5 minutes.
- Magnet turned the wrong way
- Rotation monitor incorrectly connected; refer to “Connections” on
pages 11 -12.
- Too wide a gap between the magnetic sensor and magnet; max 15 mm
- Broken belt
- Belt slipping
- Stuck rotor
- Magnetic sensor or magnet not intact
Overtemp. motor
Probable fault cause
Alarms and trips if motor winding temperature is too high.
The thermal contact in the motor reverts to normal mode when the
temperature drops.
See "Overcurrent" on page 9.
Overvoltage Alarms and trips if the connection voltage exceeds 276 V for more than
4-5 seconds
.
