POSITIONING AND ADJUSTMENT OF SENSOR ELEMENTS FOR "ML" AND "MT" SERIES:
As already mentioned, the pre-assembled JANUS "ML" and "MT" kit consist of a vertical light
curtain and of one ("ML" series) or two ("MT" series) horizontal sensor element in which the
Muting sensors are integrated.
The system is equipped with a VERTICAL adjustment of the sensor elements to solve the
following problems:
Incorrect and non-continuous sensor beam interception by the material in movement.
Need to reduce the beam intensity when transparent objects (i.e. glass, plastic, etc)
are detected.
At the operating range limits (1 ÷ 2,5m) or in dusty environments, it would be necessary to use
the ANGULAR adjustment to reach the maximum signal intensity. (REER advise against this
operation with transparent materials).
Figure 15 shows the two axes (horizontal and vertical) on which to operate.
To make the adjustment:
loosen the Allen screws;
operate on the arms to make the adjustments;
tighten the Allen screws.
Figure 15
NOTE: For installations that do not require any particular adjustments, the ML and MT
models are pre-aligned and do not require further regulation.
