Mounting
Mount the ROD4…plus so that the area being monitored is within the measurement range
of the device.
Attention!
Because of the optical scanning principle, only objects with good reflective properties are
detected directly in front of the sensor window.
Physical damage to the sensor (e.g. due to collision or climbing on) should be prevented by
using a protective enclosure. If using an enclosure, the entire front cover of the device must,
however, remain unobstructed.
In order for the ROD4…plus to function optimally, it must be mounted in a favourable posi-
tion. You should make every effort to observe the following points:
• Position the ROD4…plus such that it has maximum protection.
• The mounting location and the electrical supply should be located as close as possi-
ble to one another.
• The ROD4…plus is to be mounted so that the area being monitored is within the
measurement range of the device.
• The mounting position of the ROD4… plus must offer protection from humidity, soil-
ing, as well as temperatures below 0°C (ROD4 plus, ROD4-50 plus) or -20°C (ROD4-
08 plus, ROD4-56 plus, ROD4-58 plus) and above 50°C.
• The mounting location is to be selected such that the possibilities for mechanical
damage are minimised. Exposed locations are to be equipped with additional protec-
tive guards or loop guards.
• Reinforcements, enclosures, mounting alcoves and other machine elements must not
result in an obstruction in the field of vision.
• Retro-reflectors or very reflective surfaces, such as certain metals or ceramics, are to
be avoided near the detection fields and at the height of the scanning plane as these
may result in measurement errors.
• To ensure a constant detection height at every point in the measurement range, the
ROD4…plus, and thus the beam plane, is to be mounted parallel to the reference
plane.
• If the ROD4…plus is used without start disable or start test with automatic start/
restart, a start warning (optical/acoustic) is to be provided.
• The ROD4…plus must not be used as a climbing aid. If there is a risk of this, a suit-
able, inclined (45°) protector is to be mounted.
The device dimensions and the reference of the scanning plane to the device edges can be
found in the dimensioned drawing (see figure 9.3 on page 47). Here, the zero point for the
distance measurement is the axis of rotation of the rotating mirror (
a
system BT ROD4…plus, see chapter 8.2.6.
Notice!
Under certain circumstances, a larger measurement inaccuracy may occur with strongly re-
flective backgrounds (e.g. retro-reflectors).
