6 Common device functions

6.1 Failure monitoring

Following possible error sources are monitored continuously when SENS = ON/AUTO:
Source
Feedback signal PIN 13
4... 20 mA
Feedback signal PIN 14
4... 20 mA
SSI-sensor 1
SSI-sensor 1
EEPROM
(at switching on)
CAUTION: Take care of the EOUT command. Changes will influence 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 parameterization has been set with the assistance of the valve
data sheets.
The monitor view in WPC can be used to analyse faults.
Attention: When using RC mode safety issues have to be considered. In this mode the module
is directly controlled and the superimposed control of the system has no influence on it.
FAULT
ENABLE is active, the
module does not re-
spond, and the READY
LED is off.

Data error
CAUSE / SOLUTION
There is presumably no power supply or the ENABLE signal is not 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
If the power supply exists, an attempt should be made to see whether the system
can be moved by means of the HAND+ and HAND- signals (measuring the output
signal to the valve helps).
