    I am working on a magnetic motor starter that is controlling some pumps. We are monitoring flow of water from a PLL Lead lag control module picutred below. When there is no water flow the control module has a relay built into it and sends 120 volts to the pump motor starter. In the picture below it has the P1 output labeled L & N. If we send that to the motor starter auxiliary contacts and land them wouldn’t that create a short?
    Those outputs are 120V and should go to your coil or a control relay, not your AUX contacts. As mentioned that unit has a 6A input rating with 2A output rating for each output.
