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.

Technical specifications
See technical specifications on page 13.

Installation
- 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.

Danger
Danger of electrocution!
Ensure that the safety control unit is only put into operation by
specially-trained authorised personnel.

10 Commissioning
In arbitrary order:
-
-
Damp safety sensors.
Apply operating voltage - make sure that no external voltage is applied to the
safety inputs when the operating voltage is applied (e.g. by devices with
OSSD outputs).
- Then actuate the start button if necessary.
The LEDs of the inputs and outputs used and the "Ready" LED light up.
The safety control unit is ready. The safety control unit switches through the
safety output.
- If the ready LED and the LEDs of for the applied inputs are lit 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 point 12 Troubleshooting).
NOTE
Upon initial commissioning of a safety control unit with a new configuration,
complete validation according to the relevant standards must be carried out.
11 Maintenance
The switching behaviour and sequences of every safety circuit must be
inspected at least once per year.

13 Disposal
Dispose of packaging and used parts in accordance with the regulations of the
country in which the device is installed.

Make sure that no external voltage is applied to the safety inputs
during a voltage reset (e.g. by devices with OSSD outputs).
