Voltage supply of encoder faulty (A3403 = encoder 1 and A3404 = encoder 2)

Hva betyr F109-46 ?

The encoder voltage supply (A3403 or A3404) is outside the defined range (min. DC 20 V / max. DC 29 V). This can be caused by an overload in the supply voltage, potentially tripping an internal polyswitch fuse on the DCS..B option.

• Voltage supply to encoder 1 (A3403) or encoder 2 (A3404) is outside operating range.
• Wiring fault in encoder power supply lines.
• Defective voltage regulator for encoder power.
• Intermittent power loss to the encoder.
