2.3 Sealing
Once the LRS-03 has been correctly installed, it must be sealed. The LRS-03 is provided
with the following seals to prevent tampering with the programme or configuration
(connections and cables):
Sensor seal: Once the sensor lid has been screwed in place, it may be sealed through
the hole on the side. One of the possible ways to seal the sensor is to thread a wire
through the hole and join the ends with a lead seal, as shown in the drawing below.
Signal input and output and sensor connector seal: These connectors are sealed by
fixing the back cover of the LRS-03 with the four screws provided. These screws have a
hole in the head. The four crews are placed at the four corners of the cover and are
sealed by threading a wire through the two crews on one side and joining the ends
together with a lead seal. The same procedure is then repeated for the screws on the
other side.
NOTE: For the correct working of the limiter, it is imperative to fix the back cover.
Programming button cover seal: The programming button cover is sealed by means of
the screws provided. As in the previous cases, a metal wire is threaded through the
holes in the screws and its ends joined by a lead seal. The button must be sealed after
the LRS-03 has been correctly programmed.
