MODEL ALT-XXX-3-SW

PublishTime：2023-08-17

●SymCom’s PumpSaver® Model ALT-XXX-3-SW is designed to alternate between two loads. It is commonly used in duplex pumping applications to balance the run time of two pumps (loads). The loads may run one at a time or simultaneously. The voltage designation must be specified in the part number.
●The Model ALT-XXX-3-SW uses three inputs (1 Lead, 1 Lag and 1 Stop) and has two outputs for controlling operation of the two loads. The inputs to the PumpSaver® are usually floats that close or open depending on fluid level. The Lead and Lag float switch inputs actuate latching relays and the Stop float switch input unlatches both relays. The user has the option to force one load to run exclusively at all times when the other load has been removed for maintenance or repair.
●The Model ALT-XXX-3-SW activates Load 1, Load 2, or both, based on the current adjustment knob position and the previous action. Example: In the AUTO setting, if Load 1 activated as the lead pump previously, Load 2 will be the lead pump in the current cycle.
