A16. Is there any local visual indication available to monitor the WaveRadar
operation?
A: There is no integral indicator on WaveRadar but an optional local display unit, the
RDU40, is available for installing close by. The RDU40 displays range and distance data
and is BASEEFA03ATEX hazardous zone rated. Additionally the FBM 2180 is fitted with
LEDs that flash when receiving data from the WaveRadar.
A17. How does the RDU40 connect to the WaveRadar?
A: The RDU40 can be connected via a three wire cable to the X12 terminal (the EEx i rated
terminal block) on the WaveRadar.
B. Installation – Commissioning.
B1. How do we install WaveRadar Rex?
A: The unit is normally installed by extending the sensor over the side of the platform or
structure. A mounting frame assembly is available from RS Aqua. It is designed to fit within a
gap in the platform handrails, projecting outwards to offer the WaveRadar an unobstructed
beam to the sea surface. It can be vertically rotated for ease of deployment and recovery.
When in the deployment position it provides a barrier across the gap in the handrails. This
application is particularly suitable for temporary/semi and permanent installations.
An alternative method of mounting the WaveRadar is to install it through the decking of the
host platform, or other structure, aligned vertically to the water. The technique used is to
remove a section of the decking/grating, cut an opening to suit the mounting plate and then
assemble the WaveRadar REX around the section. It is secured via stainless steel nuts and
bolts through the mounting flange plate. The mounting plate is made from stainless steel and
it is recommended that insulating bushes be fitted to the mounting bolts to prevent electrolytic
corrosion of the carbon steel decking.
It is strongly recommended that a grill or grating be used with this method and not a
solid metal plate. Use of a solid metal plate may result in the introduction of spurious
echoes.
B2. What cables should be used?
A: The recommended cables are: Power cable to ESI standard, two core 1.5sq mm.
PVC/SWA/PVC BLACK. Data cables for both digital and analogue outputs are to BS 5308,
one twisted pair 0.5sq mm. PVC/SCREEN/PVC/SWA/PVC. These can be purchased from
RS Aqua Ltd.
B3. What are the integral junction box gland hole sizes?
A There are three entry holes within the EEx e section of the junction box, being 2 x M25
and 1 x M20.
