Refer to the data sheet for the chosen configuration.
Data sheets can also be requested from elobau for customer-specific safety
control units. The information specified in the data sheet applies for customer-
specific models if this information deviates from the operating instructions.
The person installing the safety control unit must be provided with the operat-
ing instructions.
The operating instructions and data sheet must be kept in a legible condition
and in an accessible location.
Meaning of the symbols used:
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.
Information
Indicates available accessories and useful additional informa-
tion.
2 Designated use
The safety control unit is part of the overall system or machine and is for the
purpose of assuming safety-related functions.
This is done by monitoring signals, for example safety sensors, emergency-
stop buttons, position switches, no-contact protective equipment (BWS). The
product must be used only in accordance with the descriptions below.

4 Safety information
- Ensure that the safety control unit is installed and put into oper-
ation only by specially trained, authorized 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 acci-
dent prevention.
- Ensure that the corresponding fuses (see "Technical specifica-
tions") are used. Never bypass or repair any fuses.
- Ensure that the safety control unit is only used to protect against
dangers.
- Ensure that all applicable safety requirements 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 op-
erational status of the safety control unit.
There are no known residual risks, if all of the information con-
tained in these operating instructions is complied with.
5 Warning against misuse
- In case of improper or unintended use or manipulation, dangers
for personnel and damage to the machine or system compo-
nents cannot be excluded by the use of the safety control unit.
Please also observe the relevant information stipulated
ISO 14119.
- Make sure that no current or voltage peaks that are higher than
the electrical specifications of the safety control unit are caused
by any external components. Current or voltage peaks are pro-
duced, for example, by capacitive or inductive loads.
- Exceeding the electrical specifications of the safety control unit
(e.g. in the event of defective wiring or short circuits) can
damage the system irreparably. Non-compliance may result in
reduced service life.

Art.-Nr./Art. No./Réf./N° art/N° art.: 9010008B01M Version: 1.3 Date: 29.08.2017 2/9
6 Exclusion of liability
No liability shall be accepted for any damage or 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 authorized by the
manufacturer.
No unauthorized repairs, conversions or modifications are permitted for reasons
of safety and the manufacturer shall not be liable for any resulting damage.
7 Function
4 safety inputs safety inputs, that can be connected differently, connect the
safety and control outputs respectively depending on the configurable, logical
connection. In addition, there are two inputs available for reading external con-
tactors and start buttons.
Refer to the associated data sheet for the exact configuration.
Configuration options
On our website www.elobau.com eloFlex you will find the eloFlex Configura-
tor, which offers a step-by-step guide to derive your required configuration.
Clicking on underlined terms and functions serves to open an explanatory win-
dow to explain the items in more detail.
The micro-controller-controlled safety control unit can be delivered with the fol-
lowing configuration options.
Each component can be individually customised.
If an OSSD safety input is chosen, the (+) potential must be taken from termi-
nals 8, 16, 24, 32.
Upon selection of OSSD at the safety input a sensor with cross-short detec-
tion must be used or any errors resulting from cross-shorts must be ruled out.
A maximum of one external contactor input can be assigned to one safety
output.

specified safety function and corresponds to the specified properties.
* Th control output is switched on after initialization.
No input is assigned when selecting BTR, error or safety output. The outputs’
switch-on/switch-off delay time of between 0.0 s and 99.9 s can be set in
0.1 second steps.

The operating time is the maximum time permitted on a sensor between actua-
tion of both sensor contacts.
With 2-hand operation, it is the maximum time permitted between actuation of
both sensors.
Safe condition
The safety outputs are opened or with high resistance.
Hazardous condition
The safety outputs are closed or with low resistance.
8 Technical specifications
See "Technical specifications" from page 15.
9 Installation
- Installation of the safety control unit is only permitted in a voltage-free state.
- Ensure that the prescribed fuses (see "Technical specifications") are used.
- Snap the safety control unit onto a mounting rail (DIN EN 60715 TH35) in the
switch cabinet. The safety control unit is fixed.
- Connect the safety control unit.
The pluggable terminal blocks can be coded by means of pins, the sockets
in the device are inversely coded by means of coding tabs.
Danger
Danger of electrocution!
Ensure that the safety control unit is installed and put into
operation only by specially trained, authorized personnel.

Date: 29.08.2017 3/9
- If the safety input remains free:
Ensure that the contact makers of this safety input are bridged.
10 Electrical connection
- Electrical connection is only permitted in a voltage-free state.
- Make sure that the details described in the technical specifications are al-
ways complied with.
- Measures to improve the equipment’s immunity to interference from line-
conducted and radiated high frequency interference are to be taken
(DIN EN 60204-1:2007-06, para 4.4.2).
When connecting the sensor, the sensor power supply voltage (+) and (-)
terminals identified in the technical specifications are to be used.

Danger
Danger of electrocution!
Ensure that the safety control unit is installed and put into
operation only by specially trained, authorized personnel.
NOTE
Make sure that no external voltage is applied to the safety
inputs when the operating voltage is applied (e.g. by devic-
es with OSSD outputs).
12 Maintenance
Each safety circuit must be checked by specially trained, authorised personnel
in accordance with national regulations within the time-limits specified therein.
(Recommendation: in accordance with application as per EN ISO 14119)
13 Troubleshooting
- If the ready LED and the LEDs of the applied inputs light up, the outputs flash
and the error LED is off, then the safety control unit is waiting for the start
signal at input "ext. contactor /start" (see also item 13 "Troubleshooting").
NOTE
Upon initial commissioning of a safety control unit with a
new configuration, complete validation according to the rel-
evant standards must be carried out.
