Mirion Technologies R600 Ventus Controller - Manual (Page 2)

Specifications and Performance
The Quadtek R600 Control System comprises a complete schedule of
material for installation of a Quadtek High Temperature Television
System. The hardware package can be specified to work with the
complete range of Quadtek Ventus high temperature television cameras.
The Quadtek Ventus series cameras are also supplied with a mating
gimbal flange assembly, which allows for a simple four bolt fixing to a
boiler or furnace, the gimbal comprises a mounting flange, locking plate,
gimbal, shutter and sleeve. The sleeve mounts to the camera, setting the
insertion distance and providing for quick removal of the unit for
maintenance. The shutter acts as a retaining catch for the sleeve and
covers the viewing port when a camera is not fitted. By loosening the
bolts on the locking plate the gimbal can be adjusted to give ±10° of
axial movement for fine adjustment of the direction of camera/probe
view.
All cameras use a standard five meter composite cable for connection of
power, video and temperature sensing to the local Quadtek R600 Camera
Interface Unit. The cooling hoses are specific to the camera cooling
system, although all systems use a common five meter hose assembly
between the camera and Quadtek R600 Interface Unit for air cooling and
purging. The input compressed air supply is via a one meter hose
assembly to a filter regulator assembly comprising; 40 µm coalescing
filter with shut off valve, pressure relieving regulator and manual drain.
Termination of the plant compressed air supply is direct to the filter
regulator via a 1/2" BSP fitting. For water cooled systems, two
additional five meter hose assemblies and an additional one meter hose
assembly are provided for water supply and drain from the camera to the
local Quadtek R600 Interface Unit, and from there to the plant drain. All
hose assemblies use Aeroquip SH925 hose with 1/2" BSP brass fittings.
Optional coalescing filter assemblies and water filter/regulators are
available to clean coolant supplies to the specified conditions.
The system control and monitoring is provided from two wall mounted
enclosures which provide camera power, status sensing and alarm
outputs and a desk top free-standing 14” color display monitor. The R600
Camera Interface is mounted locally to the camera, while the Quadtek
R600 Control Box is located in the control room adjacent to the monitor,
where the operators can view the monitor and see the status indication.
Alternatively, both enclosures may be installed adjacent to one another
at the camera location; in this case, the voltage-free relay contacts are
used to annunciate faults in the control room.
The Quadtek R600 Camera Interface is selected with either an air flow or
water flow sensor depending upon the camera main cooling system and
operates from a low dc voltage supplied by the Quadtek R600 Camera
Control Box. The camera status is monitored by a thermocouple, coolant
flow switch and air purge pressure switch, which interfaces with a
printed circuit board providing full condition monitoring. A built-in self
test and calibration circuit are provided for simple system test and
commissioning of the status and alarm outputs to the Control Box. The
Camera Control Box can be supplied with a glanded cable entry or MIL
specification connectors, the main power supply is regulated to a low DC
supply to the local interface and a relay board provides status and alarm
indication with a remote output. An industrial grade color display
monitor provides high quality video from the camera / probe to the
operator. A full range of video monitors, switching and recording CCTV
components are available to meet specific needs. Please contact IST for
further information.
