Operating Instructions

Safety Systems with Locking ESL-IH-AR

(translation of the original operating instructions) 119138-05-10/15

3. Description of the safety function

Devices from this series feature the following safety functions:

Monitoring of the safety guard position

(interlocking device according to EN ISO 14119)

Safety function:

-The safety outputs are switched off when the safety guard is open (see chapter

6.3. Switching states on page 8

Safety characteristics: category, Performance Level, PFH

(see chapter

11. Technical data on page 23

4. Exclusion of liability and warranty

In case of failure to comply with the conditions for correct use stated above, or if the safety instructions are not followed,

or if any servicing is not performed as required, liability will be excluded and the warranty void.

5. General safety instructions

Safety systems fulfill personal protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Check the safe function of the safety guard particularly

after any setup work

after the replacement of a system component

after an extended period without use

after every fault

Independent of these checks, the safe function of the safety guard should be checked at suitable intervals as part of the

maintenance schedule.

WARNING

Danger to life due to improper installation or due to bypassing (tampering). Safety components perform

a personal protection function.

Safety components must not be bypassed, turned away, removed or otherwise rendered ineffec-

tive. On this topic pay attention in particular to the measures for reducing the possibility of bypass-

ing according to EN ISO 14119:2013, section 7.

The switching operation may be triggered only by handle modules designated for this purpose.

Prevent bypassing by means of replacement handle modules (only for multicode evaluation). For

this purpose, restrict access to handle modules and to keys for releases, for example.

Mounting, electrical connection and setup only by authorized personnel possessing the following

knowledge:

-specialist knowledge in handling safety components

-knowledge about the applicable EMC regulations

-knowledge about the applicable regulations on occupational safety and accident prevention.

Important!

Prior to use, read the operating instructions and keep these in a safe place. Ensure the operating

instructions are always available during mounting, setup and servicing. EUCHNER cannot provide any

warranty in relation to the readability of the CD for the storage period required. For this reason you

should archive a printed copy of the operating instructions. You can download the operating instruc-

tions from www.euchner.de.
