Mounting
This chapter describes the preparation and mounting of the LCUR1411 interface unit and
provides additional information on how existing fixing holes for the ESPE to be replaced
can be taken into account on mounting the C4000 safety light curtain.
4.1
Safety notes for mounting
Mounting location
The LCUR1411 should be mounted directly on the machine/system to be protected (see
chapter 4.2, 4.3). In case of use on presses and vibrators, we recommend the use of anti-
vibration mountings (see chapter 9.4).
During all mechanical work on the machine/system stands, it must be ensured the
machine cannot be damaged by this mechanical work.
Measurement of stopping/run-down time prior to dismantling the old device
Prior to dismantling the protective device to be replaced, the following must be noted:
It must be ensured an up to date measurement of the stopping/run-down time is available
for the machine/system, as this information is necessary to determine the safety distance.
If necessary, a stopping/run-down travel measurement must be performed to determine
this figure.
Document cable assignments prior to dismantling!
Prior to disconnecting the cables at terminals or connectors, the current core assignments
must be documented to enable the LCUR1411 to be connected correctly.
Safety distance
Due to the combination of LCUR1411 with the C4000 safety light curtain, the response
time may change compared to older protective devices. As a result a different mounting
location may be necessary — for a sufficiently large safety distance. It is therefore
necessary to calculate the safety distance again prior to mounting (see C4000
Standard/Advanced operating instructions, chapter “Determining the safety distance”).
Distance to reflective surfaces
The light beams from the C4000 sender may be deflected by reflective surfaces. This
problem can result in failure to detect an object (see C4000 Standard/Advanced operating
instructions, chapter “Minimum distance to reflective surfaces”).
