INTORQ | BA 14.0199 | 08/2016

Deviations in measured values

Measured value

Cause

Remedy

Voltage too high

Brake voltage does not
match the rectifier

Adjust rectifier and brake voltage to each
other.

Voltage too low

Brake voltage does not
match the rectifier

Adjust rectifier and brake voltage to each
other.

Defective rectifier diode

Replace defective rectifier by a suitable
undamaged one.

AC voltage is not mains
voltage

Fuse is missing or defec-
tive

Install fuse. Exchange fuse.
