HDLS Series Switches

WARNING

PERSONAL INJURY

DO NOT USE these products as safety or emergency
stop devices or in any other application where failure
of the product could result in personal injury.

Failure to comply with these instructions could
result in death or serious injury.

MOUNTING

All Heavy Duty Limit Switches (HDLS) have exactly the
same mounting dimensions. Mount by either of two
methods: (a) use two #10 screws from the front, or (b)
use two #10-32 UNF screws from the back. HDLS offers
the advantage of front mount construction. The
electrician will find a complete switch, with no parts
missing and ample wiring space.

With plug-in construction, wiring and conduit connection
is made to the base receptacle. This feature also
reduces downtime, since plug-in unit can be removed
without disconnecting wiring or conduit.

To mount either switch, merely tighten mounting screws,
tighten plug-in unit or cover screws, and make sure
conduit section is sealed. Use of sealant (teflon tape,
pipe dope, etc.) is recommended to seal conduit
connection.

Because of moisture condensation problems, it is not
good practice to mount the switch upside down or at the
low point of conduit runs.

WIRING

Use size #12AWG or smaller solid or
stranded wire to connect to the
pressure type connector terminals.
Spades may be up to .312" wide,
rings up to .312" dia. With spade or
ring type connections, preinsulated
connectors or heat-shrinkable tubing
should be used to provide insulation
between terminals. Circuit diagram is
shown on the nameplate.

It will be easier to wire the double­pole units by connecting lead wires to
the terminals nearest the conduit opening first. A
grounding screw is located in the housing near the
conduit opening.

Switch units with an indicator light in the cover are
furnished with the lead wires from the light connected to
the normally-open male terminals (#3 and #4) unless
otherwise specified on the order. Wires can be
unsoldered and reconnected to the normally-closed male
terminals or they can be ordered connected to the
normally-closed terminals by using a modification code
(refer to Catalog 40). Always connect these wires to the
same set of terminals used for the load. Across the
normally open male terminals (#3 and #4) the light will
be On (Fig. 1). Across the normally closed terminals (#1
and #2) the light will be Off.

ADJUSTING INSTRUCTIONS
Actuator head. For application

flexibility, actuator head may be
positioned in any of four
directions. Loosen the four captive
head screws, place head in the
desired position, and then securely
tighten the four screws.

Reversing the roller lever.

Except for the offset roller levers,
the roller arm may be reversed to face the roller to the
inside or outside of the arm.

Positioning Lever. Lever on rotary

actuated units is adjustable through 360°
around the shaft. Loosen the screw with a
9/64 inch hexagon key wrench, move
lever to desired position and securely
tighten the screw until "teller tab" can no
Ionger be moved by hand. Then tighten
the screw another 1/8 to 1/4 turn to
assure lever is tight on the shaft.
Hexagon key wrenches are provided in
adjusting tool set LSZ4005 for this
purpose.

Adjustable Length Levers. A hexagon

key wrench is required to adjust length of adjustable
levers.

Top Roller Plunger. Position top

roller plunger in desired roller
plane by adjusting the head as
explained under Actuator Head.

Side Roller Plunger. Grasp roller

with pliers and rotate it to desired
horizontal or vertical plane.

CHANGING DIRECTION OF
ACTUATION
Side Rotary. LSM (center neutral) and LSN

(maintained) listings operate in both directions and
cannot be changed. Listings with the first three letters
LSA, LSH, LSL, LSP, LSU, and LSR may be changed to
operate clockwise, counterclockwise or both. NOTE:
Instructions for adjusting switch operation are cast into
the hinged cover (Fig. 2). To change, follow these steps:

1. Loosen the head screws and remove the head from

the switch housing.

2. On the bottom of the head, insert a screwdriver in

slot provided (Fig. 2) and lift open hinged cover.

3. Referring to Fig. 3, slide cam all the way back, so

cam is free to rotate on the shaft.

Teller Tab

4. Using a screwdriver or similar tool, rotate cam to

desired actuating position (Fig. 4, 5, and 6.)

5. Slide cam all the way forward to its original position,

and close hinged cover.

6. Replace operating head on switch housing and

securely tighten head screws.

shaft to expose end of pin plunger.

3. Refer to Fig. 8 and select correct pin plunger

position for desired direction of actuation.

4. Insert the pin plunger in the position providing

desired direction of actuation.

5. Replace the operating head on switch housing and

securely tighten head screws.

GRAVITY RETURN HDLS

Listings beginning with LSS are gravity return devices. During
installation and setup, note the following:

1. Operate and release points exchange locations when

shaft is rotated 180° (Fig. 9).

2. Switch is near operate-release points when shaft slot is

parallel to switch's long axis (Fig. 9).

3. The switch should be installed so gravity return of the

actuator releases the switch.

PROPER APPLICATION OF LIMIT SWITCHES

To achieve greatest reliability and longest life possible, limit
switches should be installed as outlined in NEMA lCS2-225.
