12 Troubleshooting
12.1 Troubleshooting
The unit has many self-diagnostic options.
• It monitors itself automatically during operation.
• It indicates warnings and faults via IO-Link and via display (even if the display is deactivated).
• If a fault is found, the outputs are set according to the setting of the parameters FOU1 and FOU2.
Display Warning Error Status LED Type of error or event Corrective measures
Err X unit faulty
u
Replace the unit.
SIM + PW
(alternately)
X Simulation function active
IO-L X Optical identification function
active
OFF X Supply voltage too low. u Check / correct the supply voltage.
u In 2-wire operation: Check / correct
the connected load.
SC1 X OUT1 flashes Short circuit switching output
1.
u
Check switching output 1 for short
circuit, eliminate fault.
SC2 X OUT2 flashes Short circuit switching output
2.
u
Check switching output 2 for short
circuit, eliminate fault.
SC X OUT1
and OUT2
flash
Short circuit switching output
1 and switching output 2. u Check switching outputs 1 and 2 for
short circuits; Remove the fault.
PArA X Parameter setting outside
the permissible range. u Repeat parameter setting.
u
Change parameter setting
u
Carry out [APPL] or [btb] reset.
See:
Reset sensor / parameter
( Ò / 29)
OL X Above the measuring range:
measured value greater
+5% VMR
u
Check / reduce pressure.
UL X Below the measuring range
u
Check / increase pressure.
Loc X Setting keys on the unit
locked, parameter change
rejected. u Unlock.
C.Loc X Parameter setting via keys
locked, parameter setting is
active via IO-Link communi-
cation. u Finish the IO-Link communication
before parameters are set on the
sensor.
S.Loc X Setting keys locked via pa-
rameter setting software, pa-
rameter change rejected. u Unlock sensor via parameter setting
software.
