Vd(700) lesser than 500[-V]
Details:
In Vd detection, which is done at the beginning of process control, the
measured potential (Vd) is converted to the potential when -700 V is
applied to the drum (Vd700) and used to check the potential sensor.
• Potential sensor probe connector disconnected
• Potential sensor probe defective
• Disconnect and reconnect the harness connecting the IOB and
potential sensor board, then check the sensor again.
• If this does not solve the problem, replace the potential sensor
probe.
