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 to be applied on industrial machines, in order to realize
emergency stop and end position monitoring circuits for movable guards. With these
modules, it is possible to create systems with safety category up to SIL CL 3 acc. to
EN 62061 and up to category 4 / PL e acc. to EN ISO 13849-1.
3.2 Device functions
- Safety function performed by the module: upon opening of at least one channel,
the safety relays must open their output contacts within the defined reaction time.
The safety outputs of the module are enabled only if the channels CH1 and CH2 are
consistently closed and after activating the START signal.
- Input with 1 or 2 channels.
- The SIL 3 / PL e safety function is only available with the two redundant inputs
configuration.
- Choice between automatic start, manual start or monitored start.
With reference to the "automatic" operating mode, consider RES 1.2.3 of the
Machinery Directive 2006/42/EC: "For machinery functioning in automatic mode, the
starting of the machinery, restarting after a stoppage, or a change in operating condi-
tions may be possible without intervention, provided this does not lead to a hazardous
situation".
- Connection of input channels of opposite potentials.
- Can be connected to semiconductor outputs (e.g. light barriers), to electromechani-
cal contacts or to magnetic safety sensors.
- 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 CH1, CH2 and for the power sup-
ply voltage.
- Short circuit detection function of the control elements by means of safety system
with self-monitoring and redundancy.
- Snap-mounting on DIN rails.
3.3 Intended use of the device
- The device described in this manual 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 this manual is
prohibited.
- Any use other than as expressly specified in this manual shall be considered unin-
tended 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
