ABSENCE OF 230V SUPPLY WITH BACKUP

Logical variable :

 DPT230V

Incident codes KP02 :  

7

KP07 icon :

Description

The supply presence voltage relay is tripped (PT230V = 0).
The compressor casing resistors and the anti-freeze resistors on the hydraulic circuit are no longer fed.

Action

F

 Immediate machine halt.

F

 The fault is displayed on the screen.

F

 The remote fault report is delayed for 6 minutes.

Resetting

The machine restarts 

automatically

 20 seconds after the 230 V supply has been restored.

Trouble-shooting

Solution

Wiring fault on 230 V supply.

Wiring fault on voltage presence relay.

Vérifier les connexions et la tension de l'alimentation
230 V qui arrive sur la machine.
Vérifier le câblage du relais de présence tension.
