The model 261 series alternating relay is designed for duplex pumping systems where it is desirable to equalize pump run time. In the overcurrent relays the current is set by the adjusting screw on the relay. This alternating action is initiated by a control switch such as a float switch manual switch timing relay pressure switch or other isolated contact. Relay logic provides you with a guide for using ncd relay controllers and how they can be wired for many types of applications.

The overcurrent relays connected to the three phase conductors only control one relay in one phase alternating current circuits and the three phase conductors control the normally closed contact in the control circuit. Use relay logic to control the forward or reverse direction of motors. A the control switch float pressure or other isolated contact is connected between the l1 terminal and the. Duplex alternating relays are used in special applications where the optimization of load usage is required by equalizing the run time of two loads.

Selector switch allows alternating or individual operation of either load. A dpdt cross wired alternating relay can be used with three input devices. Use relay logic to control lights using relays in standard applications as well as 3 way switching application. Figure e is the same function but shown for dpdt cross wired alternating relays that have the input voltage connected to pins 5 6 instead of pins 3 6 as shown in figure d.
