10.1.3
Run the cable from the sensor along the foot of the rail on the cess or field side and fix to
each rail clip using cable ties and into the trackside Cabinet.
10.1.4
The cable must route through protective pipe when running across the “4 foot” or “6
foot”, in third rail applications the cable should pass through robust insulated pipe work
below the conductor rail.
10.1.5
Route the cable within the Cabinet to the Control box. The sensor cable is armoured and
the ends will need to be prepared prior to connection.
10.1.6
Remove the two screw connector strip cover screws and route the sensor cable through
the cable gland and terminate all three cores as indicated.
10.1.7
Cable connections are as follows:
Control Box:

Wheel sensor – Single Direction Operation
On Bi-directional track where the pump operation is required in one direction, a special wheel sensor
arrangement is available.
The system comprises of two wheel sensors and one link enclosure mounted in the cabinet. The actual
Sensors look identical but are marked to identify them. The most obvious difference is that one sensor
uses 3 core armoured cable and the other uses 4 core armoured cable. This is how the sensors will be
identified; with a number 3 or a number 4 printed on the Sensor Bracket.
Positioning the Wheel sensors
The following sketch shows a typical Cabinet / EasiBlade Installation, as described in this manual.
