Function

The emergency stop safety switching device ESM-BA3.. is

designed for safe isolation of safety circuits according to

EN 60204-1 and can be used up to safety category 4, PL e

according to EN ISO 13849-1.

The internal logical system closes the safety contacts when

the start button is pressed.

When the safety switch is opened, the positively driven

safety contacts are opened and safely switch the machine

off. It is ensured that a single fault does not lead to a loss of

the safety function and that every fault is detected by cycli-

cal self-monitoring no later than when the system is swit-

ched off and switched on again.

Electrical

Connection

•

When the 24 V version is used, a safety transformer

according to EN 61558-2-6 or a power supply unit with

electrical isolation from the mains must be connected.

•

External fusing of the safety contacts (6A slow-blow or

8A quick-action or 10 A gG) must be provided.

•

A maximum length of the control lines of 1000 meters

with a line cross section of 0.75 mm

must not be ex-

ceeded.

•

The line cross section must not exceed 2.5 mm

•

If the device does not function after commissioning, it

must be returned to the manufacturer unopened. Ope-

ning the device will void the warranty.

Installation

As per EN 60204-1, the device is intended for installation in

control cabinets with a minimum degree of protection of

IP54. It is mounted on a 35 mm DIN rail according to DIN

EN 60715 TH35.

Safety

Precautions

•

Installation and commissioning of the device must be

performed only by authorized personnel.

•

Observe the country-specific regulations when installing

the device.

•

The electrical connection of the device is only allowed to

be made with the device isolated.

•

The wiring of the device must comply with the instruc-

tions in this user information, otherwise there is a risk

that the safety function will be lost.
