Standard Function Blocks
- 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 on switch-off 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
=
0
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 10: Input parameter StEn is not high when switching on via Y1On /
Y2On. This message disappears automatically as soon as
input parameter
StEn = 1. This is not an fault, but is important
to bear in mind.
- Bit 11: Invalid combination: Y1On = 1 and Y2On = 1
Remedy: Check switch, cable, input card and all conditions.
Check the software to ensure both valves cannot be driven
simultaneously (see 4-107 and 4-109) and then reset (input
parameter
RSET)
