7.8 Behaviour in the event of an error
Function:
In the event of an error the valve moves to the error position.
Notes: Moving to the error position is only possible with full power supply. This behaviour is not a
safety position. The valve must be operated with a GEMÜ 1571 emergency power supply module
(see accessories) to ensure the function in case of voltage loss.
Error position:
Closed, open or hold (adjustable via IO-Link).
