*Precharge: After starting a job and prior to opening the dispense valve, the fluid pressure is increased to try to match the dispensing pressure. This helps the consistency of the dispense.

◆Shaded areas indicate the precharge is active.

†Only applies to command signals when either “Command Cable” or “gateway” is selected as “Com- mand Value Source”. In systems containing an automation gateway DGM, when “Digital” is selected as the “Command Value Type”, the “Digital CMD 1” and “Digital CMD 2” inputs set the command.
