Voltage supply of encoder faulty (E3405 = encoder 1 and E3406 = encoder 2)

Hva betyr F109-146 ?

The voltage supply of the encoder (E3405 or E3406) is not within the defined range (min. DC 20 V / max. DC 29 V). This may be due to an overload, causing the internal polyswitch fuse to trip.

• Voltage supply to encoder 1 (E3405) or encoder 2 (E3406) is out of operating specifications.
• Faulty power wiring to the encoders.
• Defective internal voltage regulator supplying the encoders.
• Intermittent voltage drop affecting encoder operation.
