24 V supply

Was bedeutet 15 ?

The supply voltages 24V_C and/or 24V_P are too low, falling below the required operating threshold for the unit's electronics. This inadequate voltage supply can lead to unpredictable behavior or complete unit shutdown.

• Low or unstable 24 VDC auxiliary supply voltage.
• Faulty external 24 VDC power source.
• Wiring issue with the 24 VDC input.
• Internal 24 VDC power regulation failure.
• Parameter P0007 (24V fault reaction) settings.

1. 1

   Check the 24 V supply voltages 24V_C and/or 24V_P to ensure they are within the permissible range (24 V ± 25% with residual ripple max. 13% per EN 61131-2).

2. 2

   Reset the fault by switching off the DC 24 V supply voltage.
