Error messages
Any fault that is detected will be stored in the corresponding error data
word (
SSNR) of DB015 (1st data block), until the fault has been fully dealt
with.
• Error messages in DB015
- Bit 00: Invalid operation of input parameter Y1On or Y2On
Remedy: See section entitled “Function”. Once the error has
been rectified, reset (input parameter
RSET)
- Bit 01: Valve acknowledgement input parameter S1 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 S1 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 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 S1 goes to its start
position during operation (input parameter S1 goes high while
output parameter Y1 = 1)
Remedy: Check switch, cable, input card and all conditions
and then reset (input parameter
RSET)
- Bit 04: Valve Y1 not in its start position (off) when switched on, i.e.
signal at input parameter
S1 • 1
Remedy: Check switch, cable, input card and all conditions
and then reset (input parameter
RSET)
