Notes for Designing PC Board and Circuit

Use 1.6-mm-thick glass epoxy PC board with drilled holes. •

Design a circuit so that the LB series can operate within the rated voltage and current range. Make sure that inrush current and voltage do •

not exceed the rating.

Minimum applicable load is 5V AC/DC, 1 mA on gold contacts. Applicable range is subject to the operating condition and load. •

Since the • *2.8-mm-wide terminal touches the PC board as shown on the right, short circuit may occur with pattern lines. Design a circuit

that prevents short circuits.

Note: When using the LB series with a rubber boot or terminal cover, make sure to note the dimensions on page 37 and

38.

Turn off the power to the LB series control units •

before installation, removal, wiring, maintenance, and

inspection. Failure to turn power off may cause elec-

trical shocks or ﬁre hazard.

To avoid burning your hand, use the lamp holder tool •

when replacing the lamps.

For wiring, use wires of a proper size to meet voltage •

and current requirements. Solder correctly according

to the instructions in "Wiring" and "Notes on Terminal

Cover." Improper soldering may cause overheating

and create a ﬁre hazard. Also, when using tab termi-

nals, use receptacles of appropriate size.

Wiring

1) Solder the terminals at 350°C within 3 seconds using

a 60W soldering iron. Sn-Ag-Cu type is recommended

when using leadfree solder. When soldering, do not

touch the LB series with the soldering iron. Also ensure

that no tensile force is applied to the terminal. Do not

bend the terminal or apply excessive force to the

terminal.

2) Use non-corrosive liquid ﬂux.

Terminal Cover

Solder/tab terminal

Insert the terminal cover into the contact 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.

After wiring, the terminal covers cannot be installed.

Standard Bezel

Flush Bezel

Operating Environment

Do not use the LB series where corrosive gases exist or •

under an environment exceeding the operating tempera-

ture and humidity ranges. Otherwise, damages due to

contact failure or change of surface color may occur.

Major parts of the switch are plastic. Scratches or dam- •

ages may occur when scraped with a sharp object or

applied with excessive load or shock. Note that this may

cause operation and appearance failure of the operator

and bezel.

Adherence of detergent, cutting oil, or special chemicals •

to the switch may result in operation failures and appear-

ance failures such as change of surface color.

Handling

Contacts (micro switch)

When using NC (normally closed) and NO (normally open)

contacts of the same microswitch, avoid connections of

different voltages, or connections of different types of power

supplies. Failure to observe this instruction may cause a

short-circuit.

Protection against oil (IP65)

The LB series has been tested according to JIS C 0920:

Appendix 1 by using water insoluble cutting oil Class N3,

No. 8 (JIS K 2241) to prove that the switches will not be

damaged by oil drops or splashes. This may not apply to

special types of oils. Contact IDEC for details.

Removing and Installing the Contact Block

1) Turn the locking lever on the contact block in the direction

opposite to the arrow on the housing. Then the contact

block can be removed.

2) 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.

exceed 0.7 N·m. Do not use pliers. Excessive tightening will

damage the locking ring.

Replacing the Lens and Marking Plate

Removing

[Standard Bezel]

1) From the opposite side of the TOP marking, remove the

operator (lens, marking plate, and lens holder) using

the optional lens removal tool (MT-101) by gripping the

recesses of the color lens. Removing from the TOP side

may damage the metal bezel.

[Removing the Operator (standard bezel)]

[Flush Bezel]

1) Push the tip of the ﬂat screwdriver to the groove of the

color lens and pull out the operator (lens, marking plate,

lens holder).

[Removing the Operator (ﬂush bezel)]

2) Remove the marking plate by pushing the lens from

the rear to disengage the latches between the lens and

holder, using the screwdriver as shown below.

[Removing the Lens]

Note) The translucent in the lens holder cannot be removed

because this ﬁlter is sealed to make the unit waterproof and

oiltight.

Installing

Insert the marking plate into the color lens, and press

the lens onto the lens holder to engage the latches. Pay

attention to the orientation of the marking plate.

Notes on replacing the LED Unit

When replacing the LED unit, make sure that static

electricity is not applied.

Make sure that the LB series has cooled down before

replacing the LED unit. To avoid burn injuries, be careful not

to touch the unit while it is still hot.

Notes on Using Receptacles

1) Use #110 tab receptacles, 0.5 mm-thick.

2) When connecting the terminals on the left and center,

make sure that surfaces of the receptacles face each

other. Otherwise, short-circuit may occur.

3) Apply only horizontal force against the panel to the tab.

The switch may be damaged if a force other than a

horizontal force is applied.

Maintained Pushbuttons

Do not replace the buttons when the pushbutton is in the

maintained position. Replacing the button in the maintained

position may damage the internal mechanism. Also, do not

remove the contact block with the button in the maintained

position. The contact may not operate properly when the

contact block is remounted. Make sure to push down fully

when using the pushbuttons.

Pushbuttons, Illuminated Pushbuttons,

and Lenses with Switch Guard

Do not apply force to the switch guard when the switch

guard is not attached to a panel. When opening the switch

guard, do not open more than 180°. The hinge may break.

Selector Switches

When turning the operator or key, make sure that they are

turned to the each position properly.

Selector Switches with Key

Observe the following instructions to prevent malfunction or

damage.

Insert the key to the bottom of the key hole.•

Do not remove the key from any key retained position.•

Besides the standard key (key number 0H), six other key • numbers are available. Use a key of the matching number

with the key cylinder. The standard key does not have a

key number indication.

Keys are available in two types. • Key numbers 0H (standard), 1H, and 2H are reversible

keys which can be inserted in two ways.

Key numbers 3H, 4H, 5H, and 6H are non-reversible

keys. Make sure of correct insertion direction.

Instructions

Installing the Rubber Boot

When using in places where the switches are subjected to

water splash or an excessive amount of dust, make sure to

use the optional rubber boot.

As shown in the drawing below, ➀ remove the gasket from

the operator, and ➁ attach the rubber boot from the front

(button side).

Standard Bezel

For rectangular and square units, pull out the seals of the

rubber boot and place them around the operator sleeve as

shown below. Make sure that the seals are not twisted or

tucked inside and that the gasket is removed, otherwise

waterproof and dustproof characteristics are not ensured.
