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 safety modules to which these usage instructions refer are devices specifically
designed and manufactured for use on industrial machines. The safety function is a
type IIIA two-hand control acc. to EN ISO 13851. Pressing both of the two enabling
buttons within the predefined time range for synchronised actuation, this activates the
safety output. Upon releasing at least one of the buttons, the safety output is deactiva-
ted within the specified release time.
3.2 Device functions
This device can be used as a module for two-hand control devi-
ces acc. to EN ISO 13851 (Type III A) or as a module for synchroni-
sm control, in safety circuits up to category SIL 1 acc. to EN 62061,
up to to Cat. 1 / PL c acc. to EN ISO 13849-1:2015
- Input with 2 channels.
- Output contacts: 2 NO safety contacts.
- Connection of input channels of opposite potentials.
- Short circuit detection function of the control elements by means of safety system
with self-monitoring and redundancy.
- LED indicators for switching state of the channels 1, 2 and for the power supply
voltage.
- Without muting input, no bridging of the safety function.
- 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
