Gr eat care should be taken when
handling mat sensors. Never pick the
sensor up or drag it around using the
cables. Never bend a mat at a radius less
than 300 millimetres. Keep mat sensors
flat whenever possible. Always store
flat. Mat sensors with one edge longer
than 1 metre should be handled by two
people.
(i)
No devices other than those
specified in this manual should be
connected to the internally generated
power supply of the system.
(j)
After installation the machine/mat
system must be commissioned in
accordance with section 4 of this
manual.
(k)
Any cover s r emoved dur ing
installation must be replaced as soon as
possible.
3.2 SENSOR INSTALLATION
3.2.1 SENSOR MOUNTING SURFACE
The surface on which the sensor is
mounted must be sound and reasonably
flat. The sensor can tolerate minor
irregularities
but
sharp
edges
or
projections greater than 1mm may cause
premature degradation. Where the surface
is rough, cracked or breaking up, it
should be treated using proprietary
sealing and levelling compounds.
3.2.2 SENSOR FIXING
The sensor(s) must be fixed permanently
in
position.
Tapeswitch
aluminium
edging should be used around the outer
edge of the sensor. This specially
designed edging comes in two parts, a
base and a cover. The cover provides a 20
degree ramp to prevent a tripping hazard
at the outer sensor edges. The base can
accommodate
sensor
wiring
which
protects the cables from damage and acts
as a conduit to route the cables to the
control unit. Type AE

13 edging is
illustrated in Figure 12 and AE

C corner
pieces in Figure 13. At the junction of
several mats, the mats should be fixed to
the floor using double sided tape.
