Signal Measurement On Controller (Sevcon) - HAKO Hakomatic B 1100 Service Booklet

9.1.1 Signal Measurement at the
Drive Controller (SEVCON)
During test of the drive controller, the following points should be checked since
faultless operation of the drive controller is not possible without the described
signals applying accordingly.
The drive controller is designated by A6 in the circuit diagram and is supplied with
36 V even though some of the signals are 24-Volts signals.
The drive controller is a pulse controller activating the motor by the pulsed voltage.
In case of full throttle forward ride, battery voltage always applies at the motor.
1. Is F51-160A fuse okay?
2. Is battery voltage applying at drive controller?
3. Is battery minus connected at drive controller?
4. Is battery voltage applying at A6-X51:2 after switching key switch ON?
