Application

This product is an emergency stop switch authorized by TÜV Rheinland according to

IEC60947-5-5 compatible with the AS-Interface Safety at Work. When used in combination with

the safety monitor that is programmed appropriately, this switch operates as an emergency stop

switch applicable to safety category 4 in compliance with EN954-1 and IEC61508 SIL3. For this

purpose, this product generates 8x4-bit code tables defined specifically for the product, and is

scanned in each AS-Interface bus cycle by an AS-Interface master. At the same time, the data is

checked by the safety monitor. The safety loop consists of this product, the safety monitor, and

an actuator connected with the safety monitor.

To set an address while mounting this product on the panel, more than

60mm space is necessary on the left side in terms of the AS-Interface

communication unit. Note that adequate space cannot be allocated by

the distance specified with minimum mounting pitch. If adequate space

cannot be allocated, set the address before installing the product on the

panel or set the address after removing the AS-Interface

communication unit from the operator.

Notes for removing the AS-Interface communication unit

(1)

While removing the AS-Interface communication unit, do not exert

excessive force, otherwise the switch may be damaged.

(2) An LED lamp is built into the AS-Interface communication unit for

illuminated pushbuttons. When removing the AS-Interface communication

unit, pull the AS-Interface communication unit straight to prevent damage to

the LED lamp. If 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. Insert the

operator from panel front into the panel hole. Face the side without thread on the operator with

TOP marking upward, and tighten the locking ring using ring wrench to a torque of 2.0 N·m

maximum.

Notes for panel mounting

The panel thickness should be within the range from 0.8 to 6.0 mm.

To prevent the ES-XW emergency stop switch from rotating when resetting from the latched

position, use of an anti-rotation ring or a nameplate is recommended.

-Installing the AS-Interface communication unit

First unlock the operator button. Align the small marking on the edge of the operator with the

small marking on the yellow bayonet ring. Hold the AS-Interface communication unit, not the

bayonet ring. Press the AS-Interface communication unit onto the operator and turn the

AS-Interface communication unit clockwise until the bayonet ring clicks.

Addressing

Turn off the power and then remove the lid of the address setting section. Connect the

programming cable to the address setting device and insert the device in the address setting

section. Then specify the address settings according to the setting procedures. After specifying

settings, be sure to replace the lid of the address setting section. Specifying address settings on

an AS-Interface slave is also possible using an AS-Interface master. Refer to the manual for the

AS-Interface master for details. Setting addresses 1 through 31 is allowed. The address

specified upon shipment is "0".

·The values shown above are the minimum dimensions for

mounting with other ø22mm pushbuttons. For other control

units of different sizes and styles, determine the values

according to dimensions, operation, and wiring

convenience.

Refer to the address setting unit instruction sheet for the operation of the address setting unit.

-Connecting the programming cable for ES-XW address setting device

The lid of the address setting device on the side of the unit can be removed. Take care not to lose

the lid, which comes off completely. By removing the lid of the address setting section, you are

able to see the terminals for connecting a programming cable. Connect the programming cable

to the terminals

Wiring

For wiring of this product, mount the connector, sold separately, to compatible cable and connect

the main unit with the cable through the connector. A special tool is necessary to connect the

connector to the cable. When mounting a connector at the end of the cable, use a connector for

termination.

The network length is a maximum of 100 meters, including all wires.

However, the maximum possible length of the wires may actually be

shorter than 100 meters depending on the type of master and

composition of the slaves. Consider the lengths of cables and wiring

topology so that voltage drops in transmission lines are no higher than

3V.

Use applicable two-wire flat cables for wiring.

A maximum of 31 units can be connected to a network. Addresses need be assigned to avoid

overlaps.

This product allows connecting safety slaves with safety equipment, and normal slaves without

safety equipment at the same time. Do not connect safety related signals to a normal slave.

The AS-Interface slaves are divided into two types: A/B slaves with expanded addresses and

standard slaves without expanded addresses. If A/B slaves and standard slaves are connected

simultaneously, the maximum number of slaves connectable to a network may exceed 31.

Setting Safety Monitor

When using this product in combination with a safety monitor, use a “2-channel forced” monitor

device with an “emergency shutdown” icon.
