Safety Precautions
Instructions
Turn off the power to the LW series control units before
starting installation, removal, wiring, maintenance, and
inspection of the products. Failure to turn power off may
cause electrical shocks or fire hazard.
To avoid burning your hand, use the lamp holder tool when
replacing lamps.
For wiring, use wires of a proper size to meet the voltage
and current requirements. Solder correctly according to the
instructions on “Wiring” and “Notes on Terminal Cover” on
page 23. Tighten the M3 terminal screws to a torque of 0.6
to 1.0 N·m. Failure to tighten terminal screws may cause
overheating and fire.
Panel Mounting
Remove the contact block from the
operator. Insert the operator into the
panel cut-out from the front, then install
the contact block.
Removing the Contact Block
Turn the locking lever on the contact
block in the direction opposite to the
arrow on the housing. Then the contact
can be removed.
Installing the Contact Block
Insert the contact block, with the TOP
markings on the contact block and the
operator placed in the same direction.
Then lock the units, turning the locking
lever in the direction of the arrow.
Notes on Mounting
Use the optional ring wrench (LW9Z-
T1) to mount the operator onto the
panel. Tightening torque should not
exceed 1.2 N·m. Do not use pliers.
Excessive tightening will damage the
locking ring.
Collective Mounting
As the locking lever can be turned eas-
ily from the rear of the units using a
screwdriver, the contact blocks can be
removed even when mounted collec-
tively.
Replacement of Lens and
Marking Plate
Removing
1. Remov e the oper ator (lens, marking
plate, and lens holder) b y inserting a
screwdriver into the recess of the
lens through the bezel.
[Removing the Operator]
2. Remove the marking plate by push-
ing the lens from the rear to disen-
gage the latches between the lens
and the lens holder, using the
screwdriver as shown below.
[Removing the lens]
Note:The translucent filter in the lens holder
cannot be removed because the filter
is sealed to make the unit waterproof.
Installing
For round lens types, place the mark-
ing plate on the lens holder with the
anti-rotation projection engaged and
press the lens onto the lens holder to
engage the latches. For square lens
types, insert the marking plate into the
lens, and press the lens onto the holder
to engage the latches.
Note: Make sure of correct orientation of the
marking plate.
[Round Lens Type]
[Square Lens Type]
Marking Plate and Films
For LW series illuminated pushbuttons
and pilot lights, legends and symbols
can be engraved on the marking
plates, or printed marking film can be
inserted under the lens for labelling
purposes.

Replacement of Lamps
Lamps can be replaced using the lamp
holder tool (OR-55) from the front of
the panel, or by removing the contact
block from the operator.
How to Remove
To remove, slip the lamp holder tool
onto the lamp head. Then push slightly,
and turn the lamp holder tool counter-
clockwise.
How to Install
1. To install, insert the lamp head into
the lamp holder tool, and hold the
lamp as shown in the figure below.
2. Insert the pins on the lamp base into
the grooves in the lamp socket.
Insert the lamp and turn it clockwise .
Wiring
1. Solder the terminals within 20W/5
sec or 260°C/3 sec without exerting
external force to the terminals. While
soldering, do not touch the soldering
iron to the housing. While wiring,
prevent tension from being applied
to the terminals. Do not bend or
raise the terminals, nor exert exces-
sive force to terminals.
2. Use non-corrosive liquid flux.
3. For tab terminals, Positive Lock
Connectors and Easy Lock Connec-
tors can be used.
4. Tighten the terminal screw of the
screw terminal type to a torque of
0.6 to 1.0 N·m.
Notes on Termin==
==
l Cover
[Solder/Tab Terminal]
Insert the terminal cover into the con-
tact block with the TOP markings on
the contact block and the terminal
cover in the same direction.
Note:When wiring, insert the lead wires
into the terminal cover holes before
soldering.
Notes on Wiring
When installing a terminal cover onto
the solder/tab terminal contact block,
solder the inside of lamp terminal
(toward the switch terminals) and wire.
[Screw Terminal Type]
Terminal cov er must be installed on the
control unit before wiring.
Note 1: After wiring, terminal cov ers cannot
be installed.
Note 2: When terminal covers are installed,
do not use round crimping termi-
nals.
(Wire the terminal by using fork ter-
minals or lead wires directly.
Single Board Mounting
Mounting the control units on a single
PC board offers the following features.
1. Reduced installation labor, easy wir-
ing, space saving, and standardiz-
tion.
2. Since the contact blocks on the PC
board can be removed easily using
a locking lever, LW series control
units are easy to maintain.
3. Because the LW series control units
require no studs for fastening the
control unit to a PC board, special
preparation of operation panel is not
needed.
4. For details on single board mount-
ing, contact IDEC.
