Installation Guide

The system drawing references several regulations and criteria for use in hazardous
locations. Ensure these guidelines are followed for safe and reliable operation.
The mmWave Radar should be installed directly above the material to be measured,
at a 90° angle. Avoid positioning near the process filling or emptying areas.
Check there are no obstructions between the sensor and the material.

X Limitations on use
1. The sensor must be routinely inspected to avoid build-up of dust layers if installed in
zones 20, 21 & 22 (AEx ia) or zones 21 & 22 (AEx mb).
2. Electro-static hazard – The equipment shall not be installed in a location where the
external conditions are conducive to the build up of electrostatic charge.
In addition, the sensor may only be wiped with a damp or anti-static cloth.
3. The outer enclosure is made from Valox 357U, a polyester / polycarbonate blend;
consider the performance of this material with respect to chemicals that may be present.
4. The sensor must not be used if there are any cracks or damage to the enclosure.
5. (AEx ia) The installer shall consider the total length of cable attached to the sensor.
The cable shall be considered to have parameters of 200pF/m & 1uH/m or 30uH/Ω.
6. (AEx ia) The sensor shall only be connected via resistive barriers with the following
specifications: Power ≥ 234Ω, Signal ≥ 49Ω (TX & RX ≥ 49Ω).
7. (AEx mb) Only use fuses listed: Littlefuse 0242 100mA (blue band) > 1500A breaking.
The fuses are integral to Pulsar controllers, which must be located in a safe area.
8. (AEx mb) The equipment shall only be installed in areas where there is a low risk of
mechanical danger.
9. (AEx mb) Do not use in the presence of these groups of chemicals:
Aliphatic HydroCarbons, Ketones, Esters, Alcohols or Acids.
Incorrect disposal can cause adverse effects to the environment.
Dispose of the device components and packaging material in accordance with regional
environmental regulations including those for electrical / electronic products.
Transducers/Radars
Remove power, disconnect the Transducer/Radar, cut off the electrical cable and
dispose of cable and Transducer in accordance with regional environmental regulations
for electrical / electronic products.
Controllers
Remove power, disconnect the Controller and remove battery (if fitted). Dispose of
Controller in accordance with regional environmental regulations for electrical /
electronic products.
Recycle or dispose of batteries in accordance with regional environmental regulations.
