Appendix A - Advanced Display Module (ADM)

Discrete Gateway (Automation) Setup Screen

NOTE: The Discrete Gateway Setup screen is not avail- able if an automation Discrete Gateway Module (DGM) is not attached to the system.

NOTE: If Swirl Dispensers are installed, a Swirl Discrete Gateway Module will be installed. This section is not related to that module. See Control Center Assembly Overview on page 16 for gateway identification.

This screen enables users to set Active Errors to High (default) or Low. If High is selected, alarm and error sig- nals are low during normal operation and high if an alarm or error exists. If Low is selected, alarm and error signals are high under normal operation and low if an alarm or error exists.

This screen also enables users to select the Command Value Type signal (Analog or Digital) the automation system will provide to PCF. If Analog control is selected, the user must provide an analog voltage to the proper input on the DGM. See Appendix B - Discrete Gate- way Module (DGM) Connection Details, page 115, for connection details.

If Digital control is selected and one fluid plate is installed, the user can define three digital settings for each dispense valve. If Digital control is selected and two fluid plates are installed, the user can define two digital settings for each dispense valve. The user must provide two digital signals to the proper inputs on the DGM. See Appendix B - Discrete Gateway Module (DGM) Connection Details, page 115, and the Digital Command Logic Table for connection details.

NOTE: The control mode for each dispense valve is set in the Fluid Plate x, Screen 2 (Mode Settings), page

105.For example, if Valve 1 is set to Pressure mode on the Fluid Plate x, Screen 2 (Mode Settings), then the digital commands for Valve 1 are pressure values.

The Digital Command Logic Table indicates which value each input must be set to in order to select a particular setting.
