Position of operating elements
Cod Meaning Requested code or code programming
CLC Clear code Deletion of current code
txx Delay time Setting of filter time constant
(Buffering time) xx = Switching output delay
xx {03, 06, 12, 24, 50} in ms and
xx {O.1, 0.2, O.4} in s.
OFS Offset Request for offset adjustment using ▼ and ▲ buttons
SC.H Short-circuit high Short-circuit monitoring activated
U. LO Voltage low Voltage monitoring activated
OFF Off Short-circuit or voltage monitoring deactivated
Std Standard mode Standard mode activated
HYS Hysteresis mode Hysteresis mode activated
FEn Window mode Window mode activated
U-C Voltage calibration Voltage output selected
I-C Current calibration Current output selected
Display Meaning Cause / Remedy
SC.H Short-circuit high Short-circuit between output and power supply. Check wiring.
If the switching line from the load (e.g. electrical control
device, PLC or similar) is being held at an open-circuit
potential of > 3V, or if several pressure switches are being
operated in parallel, this function should be switched off.
Disconnection: ▼ during display test, then adjust with ▼ or ▲.
U.Lo Voltage low Power supply voltage too low (<17V).
Check power supply: Load may be too large.
Disconnection: ▲ during display test, then adjust with ▼ or ▲.
E RROR M ESSAGES
Display of hardware errors or malfunctions
Display of hardware errors or malfunctions (can be switched off)
Messages generated by calling SETUP functions
Display Meaning Cause / Remedy
O.Er Output error Error at switching output: Circuit-breaker defective, feedback loop
to processor open circuit. Repair necessary.
E.Er E
2
PROM error E
2
PROM module defective or connection to processor faulty.
Repair necessary.
I.Er Initialization error Checksum of initialization data incorrect. Remedy: Call up any
SETUP function and acknowledge the setting with SP.
This error message is caused by a data error. All setup values
should therefore be checked and corrected if necessary.
C.Er Calibration error Checksum of calibration data incorrect. Recalibration necessary.
SC.L Short-circuit low Short-circuit between output and ground. Check wiring:
Power supply may be too weak for connected load (leading
to collapse of voltage, particularly with loads with a high switch-on
current such as incandescent lamps or capacitances).
UFL Underflow The applied pressure is below the measuring range:
Increase pressure until it is within the measuring range.
OFL Overflow The applied pressure is above the measuring range:
Decrease pressure until it is within the measuring range.
