Description

The ALT Pump Controls series is used to alternate between two loads and is commonly used in duplex pump-up and pump-down applications to balance the run-time of both pumps. The ALT relays have a built-in debounce time delay that prevents the relay from changing state if the float momentarily bounces, and they have a built-in switch to manually force a specific load (pump) to operate each time the input float closes. This is helpful when performing periodic maintenance or pump repair. Note the following: The ALT-xxx-1-SW alternating relays are 11-pin octal base plug-ins available in two different single-phase voltage ranges. The ALT-100-1-SW is used for 95–120 V ac applications, and the ALT-200-1-SW is used for 190–240 V ac applications Both models are designed for a single float input and feature two isolated Form C relay (DPDT) outputs with two LEDs to indicate the energized loads The ALT-xxx-3-SW alternating relays are 8-pin octal base plug-ins available in two different single-phase voltage ranges. The ALT-100-3-SW is used for 95–120 V ac applications, and the ALT-200-3-SW is used for 190–240 V ac applications Both models are designed for three float inputs (lead, lag, and stop floats). The lead and lag floats actuate latching relays that release when the stop float actuates. The units feature two LEDs to indicate the energized load(s). Must use the OT08PC socket for the 8-pin models and the OT11PC socket for the 11-pin models, for UL Rating*. *Note: manufacturer’s recommended screw terminal torque for the OT Series Octal Sockets is 12 in–lbs. Features Debounce time delay LED status indicators Invertible relay logic Built-in manual switch to force load operation ALT-xxx-3-SW offers duplexing
