Failure monitoring

Following possible error sources are monitored continuously when SENS = ON / AUTO:
Source
Solenoid A PIN 3 / 4
Solenoid B PIN 1 / 2
EEPROM
(monitored during power on procedure)
6.2

Troubleshooting

Initial situation is an operable status of the device and existing communication between the module and the
WPC-300 program. Furthermore, the parameterization of the valve control has to be done with the assistance
of the valve data sheets.
The RC mode in monitor can be used to analyze faults.
CAUTION: If using the RC (Remote Control) mode, all safety aspects have to be checked solidly.
In this mode the module is actuated directly and the machine control has no influence on the
module.
FAULT
ENABLE is active, the
module does not re-
spond, and the READY
LED is off.
ENABLE is active, the
READY LED is flashing.

Fault
Broken wire
Data error
CAUSE / SOLUTION
Probably the power supply is disconnected or the ENABLE signal is not present.
If there is no power supply there is also no communication via our operating program.
If the connection to the WPC-300 exists, the power supply is also available. In this
case the availability of the ENABLE signal can be checked via the monitor.
The flashing READY LED indicates that a fault is detected by the module. The fault
could be:

Failure detection in case of current input. Input signal below 3 mA.

A broken cable or incorrect wiring to the solenoids.

Internal data error: execute the command / press the button SAVE to delete the
data error. The system reloads the DEFAULT data.
With the WPC-300 operating program the failure can be localized directly via the
monitor.
