MODULAR SAFETY INTEGRATED CONTROLLER MOSAIC
12 8540780 • 30/03/2016 • Rev.26
Any Electro-sensitive Protective Equipment device connected to MOSAIC, must be
positioned at a distance equal to or greater than the minimum safety distance so that
the dangerous point can be reached only after stopping the dangerous movement of the
machine.
The european standard:
- ISO 13855:2010- (EN 999:2008) Safety of machinery - Positioning of safeguards with
respect to the approach speeds of parts of the human body.
provides the elements to calculate the proper safety distance.
Carefully read the installation manual of each device for specific information on the
correct positioning.
Remember that the total response time depends on:
MOSAIC response time + ESPE response time + response time of the machine (i.e. the
time taken by the machine to stop the dangerous movement from the moment in
which the stop signal is transmitted).
The MOSAIC system units are provided with terminal
blocks for the electrical connections. Each unit can
have 8, 16 or 24 terminals.
Each unit also has a rear panel plug-in connector (for
communication with the master and with the other
expansion units).
The MR2 and MR4 are connected via terminal blocks
only.
Terminal tightening torque: 5÷7lb-in (0,6÷0,7 Nm).
Install safety units in an enclosure with a protection class of at least IP54.
Connect the module when it is not powered.
The supply voltage to the units must be 24Vdc 20% (PELV, in compliance with the
standard EN 60204-1 (Chapter 6.4)).
Do not use the MOSAIC to supply external devices.
The same ground connection (0VDC) must be used for all system components.
"Describe the methods that designers can use to calculate the minimum safety distance from a specific dangerous point
for the safety devices, particularly Electro-sensitive devices (eg. light curtains), safety-mats or pressure sensitive floors and
bimanual control. It contains a rule to determine the placement of safety devices based on approach speed and the
stopping time of the machine, which can reasonably be extrapolated so that it also includes the interlocking guards without
guard locking."
