2 Placing and installation of sensors
2.1.3 Example with ground sensors
In this example a lower step section (1), a walkway
platform (2) and an upper step section (3) is heated.
Depending on number of zones and detection
safety, 2-3 ground sensors is installed.
Sensor no. 1 is the most important as this is placed
where snow is likely to appear first due to shade
and snow drift also because the spot is stepped on
by pedestrians.
Sensor no. 2 is also important as the platform is
object to water puddles. Here the shaded spot
will dry up last. If the power supply is limited, the
platform could be a low priority zone in a dual zone
system.
Sensor no. 3 is relevant if more detection safety
is required, as additional to sensor no. 1. Can be
prepared for later installation.
2.1.4 Extending the ground sensor cable
The ground sensor consists of two parts, a sensor part with a sensor
cable and a sensor tube.
A 15-meter cable is supplied with the sensor part. Approx. 0.5 m of
this cable should be coiled inside the bottom of the sensor tube,
leaving 14.5 meter to be connected with the Devireg 850 controller.
If the appropriate spot is located out of this range, a feeder cable
extension for the sensor may be needed. This sensor cable extension must be a 4-wired cable
with a diameter in accordance with the table in Appendix A – Sensor cable extension.
Note each new colour of the 4 wire cable feeder extensions (white, white, red and black)
Dual zone sensors: Do NOT join feeder cable extensions from separate zones
