Operating instructions for

emergency stop switch ES-XW/XN

SAFETY NOTE



Read this instruction sheet and the catalog for

the ES-XN/XW series emergency stop switches

to make sure of correct operation before starting

installation, wiring, operation, maintenance, and

inspection. Make sure that the instruction sheet

is kept by the end user.



Turn off the power to the ES-XN/XW before

starting installation, wiring, maintenance and

inspection of the ES-XN/XW. Failure to turn power

off may cause electric shock or fire hazard.



Use wires of a proper size to meet voltage and

current requirements. Tighten the M3 terminal

screws to a tightening torque of 0.6 to 0.8 Nm.

Improper wires and loose terminals during operati-

on will cause overheating and fire hazard. Provide

a proper protection against electric shocks.

Removing/Installing Contact Block and

Panel Mounting



Removing

First unlock the operator button. Squeeze the latch

lever on the yellow bayonet ring and pull back the

bayonet ring with force until the latch pin clicks,

then turn the contact block counter-clockwise and

pull out.

Notes for removing the contact block
1) With the button in the locked position, do not

remove the contact block, otherwise the switch

may be damaged.

2) When the contact block is removed, the monitor

contact (NO contact) is closed.

3) While removing the contact block, do not exert

an excessive force, otherwise the switch may be

damaged.

4) An LED lamp is built into the contact block for

illuminated pushbuttons. When removing the

contact block, pull out the contact block straight

to prevent damage to the LED lamp. If an excessive

force is exerted, the LED lamp may be damaged

and fail to light.



Panel Mounting

Remove the locking ring from the operator and

check that the rubber gasket is in place. Align

the anti-rotation projection on the bezel with the

recess in the panel, insert the operator from panel

front into the panel hole and tighten the locking

ring using ring wrench ES-XN9Z-T1 to a torque

of 2.5Nm. Face the side without thread on the

operator with TOPmarking upward, and tighten

the locking ring using ring wrench ES-MW9Z-T1

to a torque of 2.0Nm.

About anti-rotation

To prevent the ES-XW emergency stop switch from

rotating when resetting from the latched position with

excessive force, use of a nameplate (ES-HWAV-27) is

recommended. Align the side without thread on the

operator with TOP marking, the small ▲ marking

on the projection on the nameplate, and the recess

on the mounting panel.

When using the ES-XN emergency stop nameplate

(ES-HNAV-27).

Before installing the emergency stop nameplate,

break the projection on the nameplate using pliers.



Installing

First unlock the operator button. Align the small

▼ marking on the edge of the operator sleeve

with the small ▲ marking on the yellow bayonet

ring. Hold the contact block, not the bayonet ring.

Press the contact block onto the operator and turn

the contact block clockwise until the bayonet ring

clicks.

Notes for installing the contact block
1) With the button in the locked position, do not

install the contact block, otherwise the switch

may be damaged.

2) Make sure that the bayonet ring is secured in the

locked position.

Notes for Operation

When using the emergency stop switch for safety-

related equipment in a control system, refer to the

safety satandards and regulations in each country

and region depending on the application purpose of

the actual machines and installations to make sure

of correct operation. Before using the emergency

stop switch, perform risk assessment to make

sure of safety.



Wiring

Tighten the terminal screws to a torque of 0.6 to 0.8 Nm.



Contact Bouncing

When the button is reset by pulling or turning, the NC

main contacts cause bouncing. When pressing the

button, the NO monitor contacts cause bouncing.

When designing a control circuit, take the bouncing

into consideration (reference value: 20 ms).



LED Illuminated Switches

The LED lamp is built into the contact block and

cannot be replaced.



Handling

Do not expose the switch to excessive shocks and

vibrations, otherwise the switch may be deformed

or damaged, causing malfunction or operation

failure.



Padlock Emergency Stop (ES-XN)

The padlockable emergency stop switches can

be reset by turning only, and cannot be pulled to

reset. Do not attempt to pull to reset, otherwise

damage or malfunction may result.
