- Bit 05:
Valve acknowledgement input parameter
S2 remains high
after the valve is switched on
Remedy: Check switch, cable, input card and all conditions
and then reset (input parameter
RSET)
- Bit 06:
Valve acknowledgement input parameter
S2 remains low after
the valve is switched off
Remedy: Check switch, cable, input card and all conditions
and then reset (input parameter
RSET)
INFORMATION
If no reaction time has been set for switching off the valve
(
TOff = 0), Bit 06 will remain set until the valve returns to its
start position. This is not a fault, but is important to bear in
mind.
- Bit 07:
Valve Y2 not in its start position (off) when switched on, i.e.
signal at input parameter
S2 • 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 S1 = 0
or
S2 = 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
RSET)
- Bit 09:
Valve acknowledgement input parameter
S2 goes to its start
position during operation (input parameter
S2 goes high while
output parameter
Y2 = 1)
Remedy: Check switch, cable, input card and all conditions
and then reset (input parameter
RSET)
- Bit 12:
No signal change detected from input parameter
S1. During
the working cycle of valve Y1 (valve switching on and off), the
valve has retained its start position (valve de-energised,
acknowledgement present).
Remedy: Check switch, cable, input card and all conditions
and then reset (input parameter
RSET)
