Safety notes Section 6-1
6-1 Safety notes
Assembly, electrical connection and maintenance must only be carried
out by instructed, trained and authorised specialist personnel in
accordance with applicable regulations, after de-energising the power
supply and with the machine switched off.
The machine must be safeguarded against reactivation.
Conversions and changes and tampering in the interior of the sensor,
the data interface and the alignment tool are forbidden.
During assembly, do not knock the sensor or drop it.
The ambient conditions at the assembly location must conform to the
technical data
(see SECTION 3 Specification) .
6-2 Sensor assembly
Contrary to sensors with single triangulation, E3NT with double trian-
gulation, allows the measured object's direction of motion to be in all
three directions. Thus, the rotatory position of the sensor about its opti-
cal axis can be chosen freely
(see Figure 1 Position of the sensor) .
Figure 1 Position of the sensor
If the light spot is not completely on the same plane as the target
object (minimum object size) the distance is not determined and mal-
function can occur
(see Figure 2 Not determined distance) . If neces-
sary a trigger signal or timer function has to be applied.
