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.
Safety input 1-2
NO/NO (-/+)
NO/NC (-/+)
NC/NC (-/+)
OSSD (safe semiconductor) (+/+)
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.

There is no input assignment for the selection of BTR, fault or safety output.
The switch on/switch off delay of the outputs can be chosen from 0.0 s until
99.9 s in 0.1 second steps.

Operating time
The operating time is the maximum time permitted on a sensor between
actuation 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.

Installation
Danger
- Installation of the safety control unit is only permitted in a voltage-free state.
- Ensure that the required 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 attached.
- 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
- If the safety input remains free:
Ensure that the contact makers of this safety input are bridged.
9
Electrical connection
- The electrical connection is only permitted in a voltage-free state.
- Make sure that the specifications described in the technical data are always
complied with.
Upon connection of a sensor, the (+) and (-) sensor supply voltage must be
used by the terminals stated in the technical data.
