Configurable functions
Dual channel inputs for the OSSD of ESPE
You can configure up to seven dual channel inputs for ESPE (electro-sensitive protective
equipment), in addition to the EFI connections, for the UE 440/470. You connect the OSSD
of ESPE to these inputs.
For the input element of electro-sensitive protective equipment, you configure…
$
whether an input delay is necessary (see Page 42).
$
whether a discrepancy time is necessary (see Page 43).

The electrical connection of the ESPE connections is described in Chapter 6 "Electrical

4.2.2
OSSDs of the UE 440/470
You can configure up to two dual channel OSSDs as outputs for the UE 440/470. The
OSSDs are short-circuit proof
and cross-circuit monitored.
If the safety controller switches to the Lock-out operational status (see Page 80), the
configured OSSDs are switched off.
4.2.3
Signal output (ADO)
$
You can configure up to eight configurable signal outputs (ADO) for the UE 440/470.
With the aid of the respective signal output, the safety controller can signal specific
states. You can use this output for a relay or a PLC, for example. You can configure the
signal outputs as inverted signal outputs too.
$
If an output is configured as an inverted signal output, it is in standby mode (HIGH)
during the switch between two operating modes.
You may not use the signal output for safety-relevant functions!
You are only allowed to use the signal output for signalling.
You must never use the signal output for controlling the application or with safety-relevant
functions.
If the safety controller switches to the Lock-out operational status (see Page 80), all
configured signal outputs are switched off.
If the signal output ADO is connected directly to the Release Function Block, the Response
Time of the outputs (O1.0-O2.3) will be 15ms.
With inverted signal outputs, heed that a missing input condition such as lockout or an
actuated E-Stop, leads the signal output to switch HIGH.
In calculation of the response time, the input filter time is to be taken into account.
The electrical connection of the signal outputs is described in Chapter 6 "Electrical
installation" on Page 56.
