Auto reset mode. All monitoring functions are active. If the failure does not exist anymore, the mod- ule automatically resumes to work. Normally the monitoring functions are always active because otherwise no errors are detectable via the READY output. Deactivating is possible mainly for troubleshooting.

Page 21: Pin5 (Function Of Pin 5)
This is necessary if using valves without error detection for signals lower than 4 mA. If the valve has an error detection it goes into a defined position after switching of the output. Page 21 of 32 PID-131-U-2030 30.12.2015... -
Page 22: Input Signal Adaptation
Since this is a general PID controller, the working range of the system is defined as 100% The deactivation can be used to deactivate the velocity (speed) input PIN_9/10 (the VELO value is active). Page 22 of 32 PID-131-U-2030 30.12.2015... -

Page 26: Signal:u (Output Type And Polarity)
An output current of less than 4 mA indicates that an error occurred or the module is not enabled. It is important to ensure that the connected valve closes at currents below 4mA. (If this is not the case, the EOUT command should be used to generate a defined output signal) Page 26 of 32 PID-131-U-2030 30.12.2015... -
Page 27: Special Commands
Attention: This command does not show up in the parameter list in WPC. It has to be entered manu- ally in the terminal window. After any change of AINMODE, module default data should be applied (by pressing the corresponding button in WPC300) Page 27 of 32 PID-131-U-2030 30.12.2015... -
