Motor protection is a critical safety feature that safeguards both motors and control systems from damage. MAFA’s standard electrical controls – EL110T (Timer Relay), EL120P (PLC), EL130P (PLC), and EL140P (PLC) – can all be equipped with motor protection.
Why Choose Motor Protection for Each Motor?
- Protection Against Overload and Faults
Trips automatically in case of overload or thermal failure. - Clear Alarm Management
Alarms displayed on the PLC screen with details of the affected motor. - Enhanced Safety
Allows testing with motors disconnected in case of sensor failure. - Flexible Alarm Options
External alarm lamp connection possible (24VDC, Art. No. 214).
Alarm Functions in PLC Display
All control units have an alarm output and display the following:
- Maximum runtime exceeded
- Motor protection/thermal protection triggered
- Safety switch activated
An alarm lamp can easily be connected between terminal and output (Q4/1 – Q4/2). The lamp lights up if motor protection trips, the safety switch is off, or runtime control is exceeded.
Benefits of Motor Protection
✔ Extends motor lifespan
✔ Reduces downtime and repair costs
✔ Improves troubleshooting and maintenance safety
