CHLORINE GAS FEED Series AS-1042 Microprocessor based Automatic Switchover

Automatic Switchover system Series AS-1042 provides safe, reliable switching between two gas (pressure or vacuum) or two liquid (pressure or level) sources assuring an interrupted supply of chemical to the application. Automation of all functions is done with an internal programmable logic controller for operational flexibility, enhanced reliability, and ease of use. If needed, local manual override is continently available for operator control to maintain continuous operation.
A unique graphics mimic panel simplifies system operation. Included on the graphics panel are four multi-colored status lights for each supply source. A red light indicates valve open and dispensing, a green light indicates valve closed, amber light indicates full source in standby and white light indicates the empty source. Four front panel switches provide for the selection of automatic switchover or manual override, manual valve override, initiation of program functions, and manual alarm circuit.
An automatic switchover system when used for pressure operation consists of low-pressure switches for each source, motorized ball valves; optional manifolds bypass valves, and three expansion chambers for liquid sources.
