Other information – General
9.1 Butterfly valve (manual or pneumatic)
manual
In the case of a manual butterfly valve, the position of the lever (open / closed) can
be monitored via an optional safety switch. See also section 9.2
pneumatic
In the case of a pneumatic butterfly valve, this must be set in parameter [A40]. The
corresponding function must then be assigned to a relay in one of parameters [A1 to
A12]. Only then can the valve be opened or closed manually via the “Butterfly valve”
button.
Convenience function (only with pneumatic butterfly valve)
Significance: if the COOLING button is pressed in OFF mode, the pneumatic butter-
fly valve is automatically closed.
9.2 Safety switch for manual butterfly valve
The safety switch monitors the correct position of the lever on the tank outlet.
The function of the safety switch is configured in parameter [r10].
Parameter [r10] is not available if a pneumatic butterfly valve is configured in [A40]
Fault indication
The “butterfly valve” LED flashes if, in OFF mode:
- the COOLING button is pressed while the valve is open.
- the WASHING button is pressed while the valve is closed.
If the butterfly valve is closed in washing mode, the cycle is interrupted, provided
[r10=2] is configured.
