2.0 PREVENTATIVE MAINTENANCE
Periodic inspections are necessary to maintain the proper functionality of the L072 Side-Mounted Liquid Level
Switch for Industrial Use. The switch is a safety device that protects the equipment it serves. A systematic
program of preventative maintenance should be implemented at the time of installation. If the following
instructions are completed routinely, the switch will provide continuous, reliable protection.
2.1 MAINTENANCE PROCEDURES
2.1.1 Inspect Unit Periodically
Verify that there are no cracks or chipped surfaces on the switch’s housing. Should the enclosure become
damaged, obtain a replacement immediately.
2.1.2 Inspect Connections Monthly
L072 Side-Mounted Liquid Level Switches may be vulnerable to excessive heat and moisture. Under
these conditions, the electrical wire insulation can periodically break or peel away. As a result, the bare
wires may become exposed to the elements and incur damages.
• Inspect all wiring, carefully and replace any wires exhibiting signs of brittle insulation.
• Inspect all electrical connections to ensure tightness.
• Repair or replace any wiring, if necessary.
2.1.3 Keep Unit Clean
Periodic cleaning of the oat, pivot and magnet assembly will ensure the continual, uninterrupted
movement of the mechanism. Objects and debris may cause systematic interruptions and a loss in
equipment functionality.
CAUTION! OPEN THE CIRCUIT BEFORE REMOVING THE COVER.
ATTENTION! OUVRIR LE CIRCUIT AVANT DE RETIRER LE COUVERCLE.
CAUTION! THE COVER THREADS MUST BE CLEANED BEFORE REPLACING THE COVER.
ATTENTION! LES JOINTS DE COUVERTURE DOIVENT ÊTRE NETTOYÉS AVANT DE REMETTRE LE COUVERCLE.
CAUTION! A SEAL SHOULD BE INSTALLED WITHIN 18 INCHES OF THE ENCLOSURE.
ATTENTION! UN JOINT DOIT ÊTRE INSTALLÉ MOINS DE 450 MILLIMÈTRES DU CAS.
2.2 WHAT TO AVOID
NEVER LEAVE THE SWITCH HOUSING COVER OFF OF THE SENSOR. Exposed wires can incur damage. When
performing routine maintenance, remove the housing as necessary to inspect the sensor.
NEVER PLACE A JUMPER WIRE ACROSS THE TERMINALS TO “CUT-OUT” THE CONTROL. If a jumper is necessary
for testing purposes, ensure that it is removed prior to placing the control into service.
NEVER USE IN SYSTEMS CONTAINING IRON PARTICLES. The magnet within the oat assembly can attract the particles
and become jammed.
NEVER PUT INSULATION OVER THE SWITCH HOUSING.

3.0 REFERENCE INFORMATION
This section illustrates an overview of the L072 Side-Mounted Liquid Level Switch for Industrial Use, as
well as information on troubleshooting common problems, agency approval listings, and detailed physical,
functional and performance specications.
3.1 DESCRIPTION
The L072 Side-Mounted Liquid Level Switch for Industrial Use is a oat-actuated device designed to be
horizontally mounted within a process vessel through threaded or anged connections. The low-cost switch
is ideal for OEM applications where a single-point high or low level alarm is desired.
3.2 THEORY OF OPERATION
The switching action is achieved through
the use of an internal magnet within the
oat assembly and its interaction with
the switch mechanism. As the liquid level
uctuates inside the tank, the oat travels.
Its magnetic eld actuates the switch inside
the stem and completes an electrical circuit.
The manual override button physically
moves the oat rod to close or open the
switch. This assembly may be relocated
to either N.O. normally-open or N.C.
normally-closed positions on the housing.
3.3 TROUBLESHOOTING
The L072 Side-Mounted Liquid Level Switch for Industrial Use is designed and manufactured for trouble-
free operation over a wide range of operating conditions. Common problems are discussed in terms of their
symptoms and recommended corrective actions.
3.3.1 External Causes
An initial indication of improper operation is the failure of the controlled equipment to function (pumps
will not start or stop, signal lamps fail to light, etc). If these symptoms occur, whether at the time of
installation or during routine service thereafter, check for potential external causes rst:
• Blown Fuses
• Tripped Reset Button(s)
• Open Power Switch
• Faulty Equipment Controlled By the Level Switch
• Defective Wiring to the Level Switch

THE FLOAT CHANGES POSITION.
THE UNIT IS JAMMED. REMOVE THE LEVEL SWITCH
FROM SERVICE. CHECK THE FLOAT
ASSEMBLY FOR OBSTRUCTIONS OR
ACCUMULATION OF PARTICLES WHICH
MAY CAUSE BINDING. IF BINDING IS
PRESENT IN THE FLOAT ASSEMBLY
AND CANNOT BE CLEARED BY NORMAL
CLEANING PROCEDURES, THE ENTIRE
CONTROL MUST BE REPLACED.
THE UNIT ONLY FUNCTIONS WHEN IT IS
NOT IN SERVICE.
LIQUID IS NOT ENTERING THE VESSEL. CHECK TO ENSURE THAT LIQUID IS
ENTERING THE TANK OR VESSEL. A
CLOSED VALVE OR CLOGGED PIPELINE
MAY PREVENT MOVEMENT OF THE
LIQUID IN THE VESSEL.
THE UNIT ONLY FUNCTIONS WHEN IT IS
NOT IN SERVICE.
THE TANK LEVEL IS NOT HIGH ENOUGH
TO HAVE THE FLOAT FUNCTION.
CHECK THE FLOAT TO MAKE SURE IT
IS BUOYANT IN THE LIQUID. THE TANK
OR VESSEL MUST HAVE AN ADEQUATE
LIQUID LEVEL.
THE FLOAT IS NOT BUOYANT. THE FLOAT IS COLLAPSED AND/OR
FILLED WITH LIQUID.
CHECK THE FLOAT FOR RUPTURES,
DEFORMATION, AND ANY LIQUID
TRAPPED INSIDE THE ASSEMBLY. IF
THE FLOAT IS FILLED WITH LIQUID OR
HAS COLLAPSED, THE ENTIRE LEVEL
SWITCH MUST BE REPLACED. DO NOT
ATTEMPT TO REPAIR THE FLOAT.
ALL COMPONENTS WITHIN THE LEVEL
SWITCH ARE IN WORKING ORDER, BUT
THE UNIT STILL DOES NOT FUNCTION.
THE PROBLEM IS EXTERNAL TO THE
SWITCH.
REPEAT AN INSPECTION OF THE
EXTERNAL CONDITIONSAS DESCRIBED
IN SECTION 3.3.1.
