Operation

Alternator Function 

The TDR-A provides an alternating function, based on the opening of the remote contact “C” (Float Switch). With supply power applied when the remote contact C closes, the output relay stays in its existing condition. When contact C opens, the output relay changes state. Each subsequent opening of the contact C changes the state of the output contacts and provides the alternating function.

 

Selecting “Adjustable” option provides a Local-Remote pump selection switch on the TDR-A.

• Local - “Pump 1-Auto-Pump 2” switch is on the TDR-A

• Remote - A remote selector switch can be wired into the socket
