The CSR1 current sensing relay is designed to operate in fuel pumps with sealed switch motors, which do not contain an extra switch contact for use with a console or card system.
The CSR1 is designed to be wired in series with the pump motor. (black wires) When the pump motor activates and draws more than 0.5 amps, the CSR1 switches the red wires together, providing a motor return signal for a console or card system. The CSR1 can be located either in the pump, or in the console or card system cabinet.
