Special notes on mounting a SOLID-4 Safety Light Curtain for danger zone guarding:
➢ Calculate the safety distance according to the formula in Chapt
er 6.1.2. The resolution
determines the minimum height of the protective field above the floor.
➢ Ensure that the maximum height of the protective field above the reference plane of
1000 mm
is not exceeded and only heights equal to or less than 300 mm are considered
impossible for an adult to crawl under (also see EN 999).
➢ It must not be possible to step into the danger zone from the sides. Suitable hard guards
must
be provided.
➢ When mounting the device, ensure that it is impos
sible to pass onto the housings of the
optical components (thereby allowing entrance into the danger zone).
Note!
Positioning behind corresponding cutouts on the hard
guards on the sides prevents
stepping onto transmitter or receiver housings.
➢ Consider the
position of the last light beam before the machine. It must not be possible to
stand undetected between this light beam and the machine.
Special notes on mounting a SOLID-4 Safety Light Curtain for access gu
arding:
➢ Calculate the safety distance according to the formula in Chapter 6.
1.3.
➢ The highest and the lowest light beam and therefore the height of the protective field for
Saf
ety Light Curtains with a resolution of 14, 20, 30 or 40 mm is determined by the
requirements in acc. with EN ISO 13857.
➢ Access guarding may only be operated with the start/restart interlock function. Activate
t
he internal RES interlock function of the SD4R-E or the RES interlock function of the
downstream interface and check their effectiveness.
➢ Ensure while installing the start/restart button, that it is impossible to press this button
f
rom inside the danger zone. Make sure that the complete danger zone can be seen from
the location of the button.
6.3 Mechanical mounting
What should generally be taken into consideration during installation?
➢ Ensure that transmitter and receiver are mounted on an even surface at the same height.
➢ Use screws
for mounting that can only be loosened with a tool.
➢ Fix the transmitter and receiver in position so that they cannot be shifted. Securing
t
ransmitter and receiver so they cannot be moved or swiveled is especially important in
the close area with a narrow protective field.
➢ The connections of transmitter and receiver must be pointing in the same direction.
➢ The safety distance between the protective field and the point of operation must be
observ
ed.
➢ Ensure that access to the point of operation/
danger zone is only possible through the
protective field. Additional access points must be guarded separately (e.g. by hard
guards, additional Light Curtains or doors with locking devices).
