6.1 Failure monitoring
Following possible error sources are monitored continuously when SENS = ON / AUTO:
Source Fault Characteristics
Analogue input 14
4… 20 mA Out of range or broken wire The power stage and the READY
output will be deactivated.
Solenoid A on PIN 17 + 19 Wrong cabling, broken wire The power stage and the READY
output will be deactivated.
Solenoid A on PIN 18 + 20 Wrong cabling, broken wire The power stage and the READY
output will be deactivated.
EEPROM
(when switching on) Data error The power stage and the READY
output will be deactivated.
Module can be activated by saving
the parameters.
Profinet Interruption of the connection
Livebit error
Internal data processing
(buffer overflow, checksum)
The power stage and the READY
output will be deactivated.
CAUTION: Take EOUT settings into consideration, changes have influence on the behaviour.
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 parameterisation 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.
