- Bit 01: Valve acknowledgement input parameter S remains high after
the valve is switched on.
Remedy: Check switch, cable, input card and all conditions
and then reset (input parameter
RSET)
- Bit 02: Valve acknowledgement input parameter S remains low after
the valve is switched off.
Remedy: Check switch, cable, input card and all conditions
and then reset (input parameter

INFORMATION
If no reaction time has been set for switching off the valve
(
TOff = 0), Bit 02 will remain set until the valve returns to its
start position. This is not a fault, but is important to bear in
mind.
- Bit 03: Valve acknowledgement input parameter S goes to its start
position during operation (input parameter S goes high while
output parameter Y = 1)
Remedy: Check switch, cable, input card and all conditions
and then reset (input parameter
RSET)
- Bit 04: Valve not in its start position (off) when switched on (input
parameter
S • 1)
Remedy: Check switch, cable, input card and all conditions
and then reset (input parameter
RSET)
- Bit 08: Reset input constantly high, set too early, or EIN = 1 or S = 0
Remedy: Release reset button and press it again.
If this does not work, check switch, cable, input card and all
conditions and then reset (input parameter
