| ALT SERIES - 8-pin Plug-in Alternating Relay |
Series Description: The ALT series alternating relays are used to alternate between two loads. The ALT is commonly used in duplex pumping applications to balance the runtime of both pumps.
The ALT-S is used in single high-level float applications. When the float switch opens, the alternating relay changes state, forcing the other pump to run the next time the float closes. All ALT relays have a built-in debounce feature that prevents the relay from changing state if the switch or float contact bounces momentarily.
The ALT-X has an internal cross-connected relay and is used in dual high-level float applications. These floats are commonly referred to as lead and lag floats.
The pumps alternate as in the ALT-S version but the cross- connected relay configuration allows both pumps to run simultaneously when both the lead and lag floats are closed
These relays are also available with a built-in switch (SW option) that is used to manually force one of the pumps to run every time the float switch is closed. This is helpful when a pump has been removed for repair or for test purposes. In the case of the ALT-X-SW, the switch essentially forces one pump to be the lead pump, while still allowing the second to run when both floats are closed. |
- Debounce time delay: Prevents nuisance actuating causes by waves or spashing in the tank
- Built-in manual/ auto switch: Force lead pump operation when a pump is removed for repair or testing (on select models)
