6 Appendix
6.1 Failure monitoring
Following possible error sources are monitored continuously:
Source
Fault
Characteristic
Command signal PIN 2 / 4
LIM command
Out of range
The output will be switched off and
the READY LED flashes.
Command signal PIN 2 / 4
4… 20 mA
Out of range or broken wire
The output will be switched off and
the READY LED flashes.
Solenoids output
Wrong cabling, broken wire
The output will be switched off and
the READY LED flashes.
EEPROM
(when switching on)
Data error
The output will be switched off and
the READY LED flashes.The mod-
ule can only be activated by saving
the parameters again!
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
CAUSE / SOLUTION
READY LED is off.
Presumably no power supply is present.
If there is no power supply there is also no communication via our operating pro-
gram. If a connection has been made to the WPC-300, then a power supply is also
available.
READY LED is flashing.
The flashing READY LED signals that a fault is detected by the equipment. The fault
could be:
Solenoid error
or no signal at the input, if 4… 20 mA signals
LIM monitored input signals are parameterized.
Internal data error: press the command/SAVE button to delete the data error. The
system reloads the DEFAULT data.
With the WPC-300 operating program and ULA-310 the fault can be localized directly
via the monitor.
