Macromatic Custom DPDT Cross-Wired Alternating Relays offer a number of advantages over standard duplex cross-wired units:
Combines the function of standard DPDT cross-wired alternating relays & separate auxiliary contacts in one plug-in unit
This reduces the cost of the panel by saving space, reducing the number of components, and minimizing assembly labor
Offers Sequence On - Simultaneous OFF (S.O.S.O.) Operation--see below for additional information
Protects against failure of the STOP & LEAD switches--if both switches fail, the two pump motors will be energized simultaneously when the LAG switch closes
An optional three position selector switch is offered to alternate the two loads as normal, or lock the relay to always operate the same load first each time. In this manner, a load that has fewer hours of operation than the other load could be used more often in an effort to eventually balance the run time of both loads.
