3.3 CALCULATION OF SAFETY DISTANCE OF AN ESPE CONNECTED TO PSRW
Any Electro-sensitive Protective Equipment device connected to PSRW, 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.
ATTENTION!
The standard ISO 13855 provides the information to calculate the proper safety distance.
ATTENTION!
Carefully read the installation manual of each device for specific information on the positioning distance.
ATTENTION!
Remember that the total response time depends on:
PSRW response time + ESPE response time + response time of the machine.
3.4 ELECTRICAL CONNECTIONS
The PSRW is provided with removable of terminal blocks for the electrical connections and has 6 terminal blocks
with 4 pins each one:
