6.1 Failure monitoring
Following possible error sources are monitored continuously when SENS = ON/AUTO:
Source
Command signal PIN 9/10
4... 20 mA
Solenoid A on PIN 3-4
Solenoid B on PIN 2-1
EEPROM
(when switching on)
CAUTION: Take care of the EOUT command. Changes will influence the behavior.
6.2 Troubleshooting
It is assumed that the device is in an operable state and there is communication between the module and the
WPC-300. Furthermore, the valve control parameterization has been set with the assistance of the valve data
sheets.
The RC in monitor mode can be used to analyze faults.
CAUTION: All safety aspects must be thoroughly checked when working with the RC (Remote
Control) mode. In this mode the module is controlled directly and the machine control cannot
influence the module.
FAULT
ENABLE is active, the mod-
ule does not respond, and
the READY LED is off.
ENABLE is active, the
READY LED is flashing.

Fault
Out of range or broken wire
Wrong cabling, broken wire
Wrong cabling, broken wire
Data error
CAUSE / SOLUTION
There is presumably no power supply or the ENABLE signal is not present. Other
errors are displayed via the READY LED. If there is no power supply, there is also no
communication via our operating program. If a connection has been made, then a
power supply is also available. In this case in monitor window the ENABLE input can
be checked.
The flashing READY LED signals that a fault has been detected by the module. The
fault could be:
A broken cable or no signal at the input (PIN 13 or PIN 14), if 4... 20 mA signals
are parameterized.
A broken cable or incorrect cabling to the solenoids.
Internal data error: press the command/SAVE button to delete the data error. The
system reloads the DEFAULT data.
With the operating program the fault can be localized directly via the monitor.
