Alternating Relay – Application Data
712 Alternating Relay
In many industrial pumping applications, two identical pumps are used for the same job. A standby unit is available in case
the first pump fails. However, a completely idle pump might deteriorate and provide no safety margin. Alternating relays
prevent this by assuring that both pumps get equal run time.
The Model 712 Series Alternating Relay is designed for duplex pumping systems where it is desirable to equalize pump run
time. The solid state alternating circuit drives an internal electromechanical relay. A continuous power source and control
switch is required.
The control switch (float, pressure or other isolated contact) is connected as shown in the respective wiring diagrams. Each
time the control switch is opened the output contacts will change status. Indicator lights on the case show the internal relay
status.
Setting the top toggle switch to the “center position” alternates the load; while setting the switch to “Load 1” or “Load 2” will
lock the relay in the respected position, preventing alternation.
The alternating relay approach isn’t limited to pumping applications. The control switches could be thermostats or pressure
switches, and the loads could be fans or compressors.
