Level Sensor Calibration
Polyethylene Tanks
1. Empty tanks by executing multiple shots.
2. Relieve pressure. See Pressure Relief Procedure,
page 16.
3. With the level sensor installed, locate the teach ele-
ment. It will be marked with a “bulls-eye.”
4. Activate the teach element by holding a screw-driver
near the bulls-eye until the green LED begins flash-
ing but for no more than five seconds.
5. After a short time, the green LED will stay lit continu-
ously. This signals that the sensor is now in stan-
dard operating mode.
6. Using appropriate protective wear, check the sensor
for proper operation by reaching inside the tank and
placing hand in the area of the sensor. A green and
yellow LED with a hand next to the sensor indicates
proper functioning.
