Calculation of safety distance of an ESPE connected to MOSAIC
Any Electro-sensitive Protective Equipment device connected to MOSAIC, must be
positioned at a distance equal to or greater than the minimum safety distance S 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.
1
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).
Electrical connections
Figure 3
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, MR4 and MR8 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."
