3 DESCRIPTION
3.1 Device description
The safety device described in this manual is defined according to the Machinery
Directive 2006/42/EC as logic component for safety functions.
The contact expansion modules to which these usage instructions apply are devices
specifically designed and manufactured for use on industrial machines. Upon opening
of at least one channel, the safety function ensures that the safety relay must open its
output contacts within the defined reaction time.
3.2 Device functions
This device is suitable for the following applications: as contact expansion mod-
ule for semiconductor outputs (light barriers of type 2 or type 4) in safety circuits up
to category 4 acc. to EN ISO 13849-1, up to SIL 3 acc. to EN 62061 and up to PL e
acc. to EN ISO 13849-1 (where the respective achievable category, SIL and PL are
dependent on the upstream safety module).
- 2 inputs for OSSDs.
- Output contacts: 3 NO safety contacts, 1 NC feedback contact/EDM.
- LED indicators for switching state of the channels 1 and 2.
- Screw terminals or plug-in terminals with screw connections or spring terminals (de-
pending on the model).
- Snap-mounting on DIN rails.
3.3 Intended use of the device
- The device described in these operating instructions is designed to be applied on
industrial machines.
- The direct sale of this device to the public is prohibited. Installation and use must be
carried out by qualified personnel only.
- The use of the device for purposes other than those specified in these operating
instructions is prohibited.
- Any use other than as expressly specified in these operating instructions shall be
considered unintended by the manufacturer.
- Also considered unintended use:
a) using the device after having made structural, technical, or electrical modifications
to it;
b) using the product in a field of application other than as described in paragraph
TEChNICAL DATA.

7 INSTRUCTIONS FOR PROPER USE

7.1 Installation
Attention: Do not exceed the tightening torque of the terminal screws specified
in the present operating instructions.
Attention: Observe the wiring of the terminals: incorrect wiring can damage the
device which may result in loss of the safety function.
- Install only inside a cabinet with protection degree not less than IP54 according to
EN 60529.
- Always affix the device with the specific DIN rail adaptor acc. to EN 60715.
- Do not stress the device with bending and torsion.
- Do not modify or open the device for any reason.
- The device carries out an operator protection function. Any inadequate installation
or tampering can cause serious injuries and even death, property damage, and eco-
nomic losses.
- These devices must not be bypassed, removed or disabled in any other way.
- If the machine where the device is installed is used for a purpose other than that
specified, the device may not provide the operator with efficient protection.
- The safety category of the system (according to EN ISO 13849-1), including the safe-
ty device, also depends on the external components connected to it and their type.
