9.19 PurgeMode
Purge functions can be activated directly when the PurgeMode is selected on the LDS. Each device is allowed to set the PurgeMode. When in remote control and purging by the IMM is activated with a hard wired dosing signal, PurgeTimeout and PurgeQuantity has no effect.
When in remote control and purging by the IMM is activated with the StartDosing Method, either PurgeTimeout/PurgeCyclicIdleTime or PurgeQuantity/PurgeCyclicQuantity must be set.
After the dosing signal is deactivated again, the PurgeMode will be reset to OFF by the LDS.
