The Automatic Switchover system Series 1041 provides safe, reliable switching between two gas (pressure or vacuum) or two liquid (pressure or level) sources assuring an uninterrupted supply of chemical to the application. Automation of all functions (switchover, system initialization, configuration, lamp test, and safety functions) is done with an internal programmable logic controller for operational flexibility, enhanced reliability, and ease of use. If needed, local manual override is conveniently available for operator control to maintain continuous operation.
A unique graphic “mimic” panel simplifies system operation. Included on the graphic panel are four multi-colored status lights for each supply source. Red light indicates valve open and dispensing, green light indicates valve closed, amber light indicates full source in stand-by, and white light indicates empty source. Four front panel switches provide for selection of automatic switchover or manual override, manual valve override, initiation of program functions, and manual reset of the latching alarm circuit.
