FUSES
MEP31 controller has 2 fuses installed: F1 = 1A 250V and F2 = 2.5A 250V. When the fuse is blown, a lit LED beside the
corresponding fuse will be visible.
MEP32 controller has 1 fuse installed: F1 = 1A 250V. When the fuse is blown, a lit LED beside F1 fuse will be visible.
PROBLEM #2 – NO DISPLAY
POSSIBLE CAUSES:
1. No power to the MEP 31 and MEP 32 CONTROLLER.
2. MEP CONTROLLER failure.
DIAGNOSIS:
1. Check fuses on the MEP31 & MEP32 CONTROLLER.
PROBLEM #3 – NO BLADE SPEED DISPLAY
POSSIBLE CAUSES:
1. Fault at proximity sensor
• Bad sensor, misadjusted sensor (gap should be approx. 0.015”)
• Contamination on the end of the sensor
• Check BLADE SPEED PROXIMITY is set to YES in the parameters.
2. Fault at the MEP32 CONTROLLER
• Bad connection of sensor wiring
• Faulty MEP32 CONTROLLER.
DIAGNOSIS:
Check for LED light on the sensor – light ON indicates proximity sensor power connections are correct and sensor is
activated. Problem could be with sensor, signal wire to the MEP CONTROLLER. With blade running, proximity LED
should pulse. Likewise, the MEP CONTROLLER LED for proxy input should be pulsing. If both LEDs are pulsing with the
blade running, the CONTROLLER is the problem. If the sensor LED is pulsing but the input at the MEP CONTROLLER is
not; there is a problem between the sensor and the MEP CONTROLLER INPUT. If the LED on the sensor is not on, the
problem is with the sensor wiring or the sensor is at fault or sensor adjustment is required.
