Failure monitoring
Following possible error sources are monitored continuously when SENS = ON/AUTO:
Source
Fault
Characteristic
Feedback signal PIN 13
4... 20 mA
Out of range or broken wire.
The output will be switched off.
Feedback signal PIN 14
4… 20 mA
Out of range or broken wire.
The output will be switched off.
SSI-sensor 1
Out of range or broken wire.
The output will be switched off.
SSI-sensor 1
Out of range or broken wire.
The output will be switched off.
EEPROM
(at switching on)
Data error
The output is deactivated.
The module can be activated by
saving new parameters (press-
ing of the SAVE Button).
CAUTION:
Take care of the EOUT command. Changes will influense 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 RC in monitor mode can be used to analyse 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 in-
fluence the module.
FAULT
CAUSE / SOLUTION
ENABLE is active, the
module does not re-
spond, and the READY
LED is off.
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).
