Float Sensor Test
CAUTION: Use caution to prevent dangerous conditions when you do work in
a hazardous area.
Make sure that the area has sufficient airflow when you do a test or remove
contamination from the sensor. Make sure there are no open flames or hot
surfaces near the work area.
Sensor installed in a normally dry well
l Put the float in the HIGH position. This will cause an alarm condition in the controller.
l Put the float back in the LOW position. Make sure that the controller is not in an alarm condition.
Sensor installed in a normally wet well
l Put the float in the LOW position. This will cause an alarm condition in the controller.
l Put the float back in the HIGH position. Make sure that the controller is not in an alarm condition.
If the controller does not go into an alarm condition, look to see if the thresholds are correctly programmed in
the system. Look to see if the float is in the correct position (refer to the applicable instruction above). A
sensor or wiring fault will cause a system alarm. Do a continuity test in the wiring and junction boxes. Make
sure there is continuity with no short circuits.
