c Level Switch provides a pneumatic output si

condition.

General Instruc

The float moves a magnet into the field of a magnetically actuated pneumatic valve. The

pneumatic valve is pilot operated. An amplifying relay provides quick response.

The unit may be mounted for either high or low liquid level alarm by rotating the switch

body. Wrench flats provide ease of rotation.

High Level Pneumatic Output Signal (Direct Acting) Install with pneumatic connections

on the upper side of the body when the unit is tightened into the vessel.

Rising liquid level raises the float upward causing the float stem magnet to repel the

actuating lever magnet and seal the pilot nozzle. Resultant pilot pressure build-up triggers

the amplifying relay to pass pneumatic signal through the output port.

Low Level Pneumatic Output Signal (Reverse Acting) Install with pneumatic connections

on the lower side of the body when the unit is tightened into the vessel.

Falling liquid level lowers the float downward causing the float stem magnet to repel the

actuating lever magnet and seal the pilot nozzle. Resultant pilot pressure build-up

triggers the amplifying relay to pass pneumatic signal through the output port.

Before Installing the Level Switch  Inspect the unit for any shipment damage.  Check for mechanical clearance. The float must move freely throughout its stroke inside the vessel.  Use an acceptable thread compound to ensure a leak free fit and avoid thread galling when installing the unit into the vessel.  The unit may be mounted in any of the following installation arrangements:  2” NPT full or half coupling  3” NPT full coupling (Use in conjunction with 2 x 3” NPT bushing.

Troubleshooting Symptom Float in actuated position but no output signal. Probable Cause a. Pilot nozzle-seat worn or damaged. (No seating of flapper.) Return to the factory or replace the switch. b. Actuating lever bound up or dirty. Clean or return to the factory. c. Damaged relay diaphragm. Replace the relay assembly. d. Relay orifice plugged. Clean. e. Insufficient supply pressure adjust to 20-60 psi. f. Output line clogged. Clean. a. Pilot nozzle plugged. Clean the pilot nozzle.
