In these operating instructions

The following standard models are described:
- 470EFR2D12K_

SIL2/PLd with 2 safety outputs

- 470EFR3E12K_

SIL3/PLe with 2 safety outputs

- 470EFR3E11K_

SIL3/PLe with 1 safety output

The selected configuration can be obtained from the data sheet.
The person installing the safety control unit is to be provided with the operating
instructions.
The operating instructions and the data sheet must be kept in a legible condi-
tion and in an accessible location.
Meaning of the symbols used:

Designated use

The safety control unit is an integral part of the overall system or machine and
serves for performing safety-related functions.
This is done by monitoring signals by e.g. safety sensors, emergency-stop
buttons, position switches, no-contact protective equipment BWS. The
product must exclusively be applied in accordance with the descriptions
below.

Exclusion of liability

No liability shall be accepted for damage and operational faults caused by a failure
to observe these operating instructions. All further liability of the manufacturer is
excluded in the case of damage caused by the use of replacement and accessory
parts that have not been authorised by the manufacturer.
No unauthorized repairs, conversions and changes are permitted for reasons of
safety and the manufacturer shall not be liable for damage resulting therefrom.

Warning

Failure to observe this warning may result in faults or malfunc-
tions.
Failure to observe this warning may result in personal injury
and/or damage to the machine.

- Ensure that the safety control unit is only put into operation by

specially-trained authorised personnel.

- Only install and put the device into operation once you have

read and understood the operating instructions and are familiar
with the applicable regulations on occupational safety and
accident prevention.

- Ensure that the corresponding fuses (see technical specifica-

tions) are used. Never bypass or repair fuses.

- Ensure that the safety control unit is only used to protect against

dangers.

- Ensure that all safety requirements applying for the machine in

question are observed.

- Ensure that all applicable European directives and national

laws/directives are observed.

- Ensure that the control output is only used for displaying the

operational status of the safety control unit.

- There are no known residual risks if all of the information

contained in these operating instructions is complied with.

- In case of incorrect or unintended use or manipulation, the use

of the safety control unit does not exclude risks to persons or
damage to machine or system components.
Please also observe the relevant information stipulated in the
ISO 14119 standards.

- Ensure that no current or voltage peaks which are higher than

the specified electrical data of the safety control unit are caused
by external components. Current or voltage peaks may for
example be generated through capacitive or inductive loads.

- An exceeding of the electrical data of the safety control unit (e.g.

in the event of incorrect wiring or short-circuits) may cause
irreparable damage to the unit. Non-compliance may result in
reduced service life.

Function

2 safety inputs, that can be connected differently, connect the safety resp. the
control outputs depending on the configurable, logical connection. In addition,
there is an input available for reading external contactors and start buttons.
The details of configuration can be obtained from the data sheet.

Configuration possibilities

On our website www.elobau.com you will find the eloFlex Configurator, which
offers a step-by-step guide to derive your required configuration. Clicking on
underlined terms and functions serves to open an explanatory window to
explain the items in more detail.
The micro-controller controlled safety control unit can be delivered with the
following configuration possibilities.
Each component can be individually adjusted.

Upon connection of a sensor, the (+) potential must be disconnected from
terminals 5 and 9.
Upon selection of OSSD at the safety input, a sensor with cross-short detection
must be used or any errors resulting from cross-shorts must be ruled out.

Safety input 1-2

NO/NO (-/+)

e.g. protective door

NO/NC (-/+)

e.g. protective door

NC/NC (-/+)

Emergency-stop push-button

OSSD (safe semiconductor)

 

(+/+)

only safe sensors with PNP outputs, 
e.g. light grids

Maximum one external contactor input can be assigned to one safety output.

* When selecting the logic operator, ensure that the resulting function fulfils the
specified safety function and corresponds to the specified properties.
