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 a
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 an AS-Interface safety monitor. The safety loop consists of this product, a safety
monitor, and an actuator connected with the safety monitor.

-Removing AS-Interface communication unit
First unlock the operator button. While pushing up the white bayonet ring with force, using a small
screwdriver (width: 2.5 to 3mm) if necessary, turn the AS-Interface communication unit
counterclockwise and pull out.

-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 with the anti-rotation protrusion on the
operator upward, and tighten the locking ring.

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 operation section.

Notes for removing an AS-Interface communication unit
(1) Do not exert excessive force when using a screwdriver, otherwise

the bayonet ring may be damaged.

(2) When removing the AS-Interface communication unit, avoid rough

handling of the unit. Rough handling may damage the switch.

Notes for Panel Mounting
The panel thickness should be within the range from 0.8 to 3.7 mm. To
mount the ES-XA emergency stop switches onto a panel, tighten the
locking ring to a tightening torque of 0.88 N·m maximum using ring
wrench ES-MT-001. Do not use pliers. Do not exert excessive force,
otherwise the locking ring may be damaged.

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 device instruction sheet for the operation of the address setting device.

-Connecting the programming cable for ES-XA address setting device
The lid of the address setting device on the side of the unit can be removed by prying it out. 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 cabling of this product, mount the connector sold separately to the 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 must 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 normal slaves for AS-Interface 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 the “Emergency shutdown” icon.

Notes for setting up wiring
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 slaves.
Consider the lengths of cables and wiring topology so that voltage drops in
transmission lines are no higher than 3V.
Use the applicable two-wire flat cables for wiring.
