3. Each pump has an input for the temperature fail sensor often found in pumps This sensor should be shorted if the pump is good If the pump overheats then this sensor will open The sensor is connected to ground and to the sensor input for that pump If the pump controller detects an open condition in the sensor then the temperature fail lamp and output are activated The temperature fail condition will disable the pump The controller can be set using an option switch on the bottom of the controller to latch up the temperature fail condition If this option is selected then once a temperature fail condition is detected the fault will not clear until the fault condition is cleared and the reset push button is pushed or external reset input is closed If this option is not selected then the fault will clear when the sensor in the pump closes again DISABLE PUMP RUNNING INPUTS Each pump has an input which has two possible functions If the fail to start test is not activated by an option switch on the bottom of the controller these inputs are pump disables Under this condition if this input is shorted to ground then that pump will be disabled If the fail to start test is activated these inputs are pump running inputs and should be shorted to ground when ever the pump is running FAIL TO START TEST If the fail to start test is activated using the option switches on the bottom of the controller then the following sequence is used each ti
