Page 45: Troubleshooting
Troubleshooting Initial situation is an operable status of the device and existing communication between the module and the PS1 software. 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. If using the RC (Remote Control) mode, all safety aspects have to be checked solidly. -
