Application

1

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.

-Removing the AS-Interface communication unit
First unlock the operator button. Grab the bayonet ring (1) and pull back the bayonet ring until the
latch pin clicks (2), then turn the AS-Interface communication unit counterclockwise and pull out
(3)

- 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.

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.

Operator uni

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.

two projections on the bayonet ring are securely in place.

Addressing

10

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".
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

11

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.

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

12

When using this product in combination with a safety monitor, use a “2-channel forced” monitor
device with an “emergency shutdown” icon.

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.
