Description
The safety-related
F31 02
controller is a compact system located in a metal enclosure with
20 digital inputs and 8 digital outputs.
The controller is available in a model variant for SILworX and a model variant for ELOP II
Factory, see Chapter 3.2. All variants are described in this manual.
The device is suitable for mounting in Ex-zone 2, see Chapter 4.1.3.
The device has been certified by the TÜV for safety-related applications up to SIL 3
(IEC 61508, IEC 61511 and IEC 62061), Cat. 4 (EN 954-1) and PL e (EN ISO 13849-1).
Further safety standards, application standards and test standards are specified in the
certificate available on the HIMA website.
3.1
Safety Function
The controller is equipped with safety-related digital inputs and outputs.
3.1.1
Safety-Related Digital Inputs
The controller is equipped with 20 digital inputs. The state (HIGH, LOW) of each input is
signaled by an individual LED.
Mechanical contacts without own power supply or signal power source can be connected to
the inputs.
Potential-free mechanical contacts without own power supply are fed via an internal short-
circuit-proof 24 V power source (LS+). Each of them supply a group of 4 mechanical
contacts. Figure 1 shows how the connection is performed.
With signal voltage sources, the corresponding ground must be connected to the input (L-),
see Figure 1.

Connections to Safety-Related Digital Inputs
For the external wiring and the connection of sensors, apply the de-energized-to-trip
principle. Thus, if a fault occurs, the input signals adopt a de-energized, safe state (low
level).
If an external wire is not monitored, an open-circuit is considered as safe low level.
