2. General safety regulaons and protecon measures

• The manufacturer and user of the system/machine on which the protection system is used are

responsible for coordinang and adhering to all applicable safety rules and regulaons under their own

responsibility.

• The protecon system guarantees funconal safety in combinaon with the superordinate control

system, but not the safety of the enre system/machine. Thus, a safety review of the enre system/

machine in accordance with machine direcve 2006/42/EC or relevant product standards is necessary

prior to use of the device.

• The operang instrucons must be permanently available at the operang locaon of the protecon

device. They must be thoroughly read and applied by every person who is tasked with the operaon,

maintenance or repair of the protecon device.

• The installaon and start-up of the protecon device may only be conducted by specialized personnel

who are familiar with these operang instrucons and the applicable regulaons on job safety and

accident prevenon. The instrucons in these operang instrucons must be followed and adhered to

uncondionally.

• Electrical work must only be carried out by skilled electricians. Safety regulaons for electrical engineering

and from the professional associaon must be followed.

• In case work has to be carried out on the switching device, it must be switched to a voltage-free posion

and checked for freedom from any voltage and secured against being switched back on again.

• If the potenal-free connecons of the safety switching contacts are supplied with a hazardous voltage

from an external source, it must be ensured that these are also switched o when working on the

switching device.

• The switching device does not contain any components that the user must service. Any warranty or

liability on the part of the manufacturer is forfeited in the event of any unauthorized modicaons or

repairs to the switching device.

• Auxiliary outputs must not execute any safety-orientated funcons. They are not fail-safe and are not

checked either by tesng.

The system must be checked for correct funcon in suitable intervals by qualied persons for

the standard-conform design of the safety system. The check must be documented in a way that

allows it to be traced at any me.

In the case of non-compliance or deliberate abuse, the manufacturer’s liability will cease.

3. General and funcon descripon

The ELMON rail 41-822 (ELMON rail 41-322) switching device is used to evaluate sensors such as safety

contact mats, safety contact edges and safety bumpers for securing crush and shear locaons.

An ASO sensor can be connected to the switching device. The steady-state current monitoring of the sensor

is made possible by an integrated terminang resistor in the sensor.

Furthermore, the device can also evaluate a sensor in four-wire technology.

If the desired steady-state current ows, the safety relays are driven and the switching contacts closed. If

the sensor is operated or the sensor circuit is interrupted, the relay switching contacts open.

A signal output with potenal-free switching contacts is available. An operaon of the sensor causes a

reacon of the signal output in accordance with the DIP switch conguraon. The signal output must not

execute any safety-orientated funcons. It is not fail-safe and not checked by tesng either.

The switching device has been designed and type-approved in accordance with EN ISO 13849-1 “Safety-

related parts of control systems” for category 3 Performance Level e. For compliance with category 3, the

safety output is set up redundantly with two independent switching elements.

In addion the device has been type-approved according to EN 62061 “Funconal safety of safety-related

electrical, electronic and programmable electronic control systems“ and can meet a safety funcon up to

SIL 3.

The monitoring state of the sensor and the applied operang voltage are indicated by LED.

If there is a fault alarm, all safety outputs are inacve.

Installaon and electrical work must be performed by authorized electricians.

The unit can be used in a household environment as well as an industrial environment up to

an altude of 2000m above mean sea level. The unit must not be operated in areas with major

temperature changes.

4. Intended use

The switching device can only fulll its safety-relevant task, if it is used as intended within specicaons.

The intended use of the switching device is the use as a protecon system in connecon with safety contact

mats, safety bumpers and safety contact edges with 8.2 kΩ resistance for steady-state current monitoring.

It is not allowed to use the safety relay in heights over 2000 m above sea level or potenally explosive

atmospheres.

A dierent use or any use going beyond the intended use is not within specicaons. The manufacturer

does not accept any liability for any damage arising from use not within specicaons.

Any use for special applicaons requires prior release by the manufacturer.

5. Applicaon example

Safety-orientated monitoring of a safety contact edge with start release via release pushbuon and separate

connuaon of the control circuits (category 3 compliant applicaon according to EN ISO 13849-1).

In order to check the funconality of the load breaking K1 and K2 relays the break contacts of these contactors

are integrated into the start circuit (Z1 Z2).

The signaling relay output is used to visualize the switching state of the safety contact strip.

7. Operang modes

7.1 Safety output

Separate or series-connected output of the control circuits (redundant connuaon of the switching contacts).

In order to use the two safety relays separately, the bridge between 14 and 23 must be removed.

7.2 Automac reset

(S1 = „ON“)

Aer removing a fault in a sensor circuit or aer a voltage failure, the switching unit will automacally release

output again.

Aenon: Automac restart of mashine! If this seng is used, it has to be ensured that no one

is able to be in the dangerous zone to avoid hazardous situaons. The integrator or operator is

responsible for the correct sengs of the controller. In no case the manufacturer is liable for

incorrect sengs or missuse.

7.3 Fault self-retaining – manual reset

(S1 = „OFF“)

Following removal a fault of in a sensor circuit, or aer a voltage failure, the switching unit will only release

the output(s) again, if the Z1 and Z2 contacts, 500 ms aer the eliminaon of the disrupon, are closed by

means of a pushbuon. This completely prevents any automac re-start. A permanent bridging of the Z1 and

Z2 contacts does not cause an automac reset.

7.4 Signaling output without any delay (RLU)

(S2 = „ON“)

In this mode of operation the corresponding signaling

output is acvated without delay, if any fault is signaled on

the corresponding channel. The output is always inacve

in the de-energized state of the switching device.

7.5 Signaling output delayed (RL)

(S2 = „OFF“)

In this operang mode the corresponding signaling output

is acvated with a delay of 0.5 seconds and then remains

acve for a maximum of 3 seconds, if a fault is signaled.
