153ESK...
7 Function
Coded, electronic safety sensor, which is operated by a non-contact coded
actuator.
Safety sensors are suitable for the following elobau safety relays:
eloFlex 470EFR...
eloFlex 471EFR...
eloProg 485EPB
485EPE08A02
485EPE08
4854EPE12
485EPE16
7.1 Coding variants
The various versions of the safety sensors arise from the different encodings
designated as type keys under point 1.2. Depending on the variant, a corre-
sponding manipulation protection is achieved.
Coded
The safety sensor accepts any eloProtectE actuator of type 153EBK001.
Type 4; low level coding level according to EN ISO 14119
Individual
The safety sensor accepts one eloProtectE actuator of type 153EBK001. This
actuator is configured individually to the safety sensor. A non-matching actu-
ator in the sensor range will result in an error.
The process for teaching-in a new actuator can be carried out unlimited times
and is descried in detail under "Commissioning" on page 8.
Type 4; high level coding level according to EN ISO 14119.
Unique
The safety sensor only accepts the eloProtectE actuator supplied. The pair,
consisting of sensor and actuator cannot be separated. If a component should
be lost and is no longer functional, both components must be replaced.
Type 4; high level coding level according to EN ISO 14119.
7.2 Safety outputs
The safety sensor has 2 short-circuit proof PNP safety outputs (OSSD), which
have a max. load of 400 mA per channel.
The safety outputs switch on under the following conditions:
- the correct actuator is detected in the operating range (safety guard closed)
- a high signal is present at both safety inputs
- the EDM input is set correctly
- no error is detected
The safety outputs switch off under the following conditions:
- There is no actuator or the wrong actuator in the detection zone
- Signal is low at one of the two inputs
- An error is detected
The two safety outputs can be connected under the following conditions to the
inputs of a safety controller:
- the input must be appropriate (OSSD signals) for clocked safety signals; the
controller must tolerate test pulses on the inputs (see Technical specifications
on page 24). Please refer to the instructions of the controller manufacturer.
Wiring examples can be found on page 30.
7.3 Safety inputs
The safety sensor has 2 safety inputs.
- Connect the safety inputs of +24 V DC for single use of the sensor.
- When using the sensor in a series connection, the safety inputs of the first
sensor can be connected to +24 V DC. The safety inputs of the following
sensors are connected to the safety outputs of the previous sensor. Please
also refer to point 11.1 "Series connection" on page 8.
- Pulses with a duration of max. 900 μs are tolerated on the safety inputs.

Wiring examples can be found on page 30.
7.4
The EDM input can be configured as "automatic" or "monitored" (see number
key).
If the EDM input is not required, the "automatic" variant must be selected and
connected to +24 V DC.
EDM input: automatic
For contactor monitoring, the open contactors must be connected to the EDM
input.
For series connection of multiple sensors all EDM inputs must be connected
to +24 V DC. The monitor for the contactors must be connected to the last sen-
sor of the chain.
Wiring examples can be found on page 30.
EDM input: monitors (start button)
Connect the EDM input to an external start button on your machine control.
The EDM input is only then recognized as set properly if after pressing the
sensor and after setting the safety inputs at least one valid start pulse is
detected.
The valid start pulse is detected when after a rising edge, a falling edge within
the allowable start pulse duration between 30 ms and 5 s is detected.
Wiring examples can be found on page 30.
7.5
The diagnostic output is positive switching, short-circuit protected and trans-
mits the various sensor states with different signals, for example, to a PLC.
The pulsed signals correspond to the timing of the yellow LED.
The various symbols are described in more detail under point 7.6.
