3.0 The Cyclops Purge Controller
The purpose of the Purge controller
is to ensure the enclosure is in a safe
condition before applying line power. To
do this it monitors air pressure and air
flow. If these two conditions meet the
control parameters this is considered
safe. To ensure that all potentially
explosive air has been purged when
power is first applied, a five minute
times period must occur prior to power
allocation, under the safe condition
mentioned above.
The Cyclops system consists of the
Cyclops controller, the vent and the
external stainless steel interconnection
tube.
The controller is sealed and no repair
is possible. This manual will guide you
through removal of the Cyclops System
and the upgrade to The Air Sentinel.
The Air Sentinel is smaller, lighter and
includes the vent integral to the controller.
This system was designed specifically for
the CLX-Ex and CLX-Ex2.
3.1 The Chassis Removal and Replacement
To gain access to the Cyclops mounting hardware it is first required to
remove the chassis
Tools Required:
A medium size Philips screwdriver
The Electronic PCB and Chassis assembly is the complete system
as shown to the right. This includes the LCD, keypad, power supplies
and cables.
Steps:
1. Remove electrical connectors to Optics PCB (2 places), the intake
solenoid, the purge solenoid and the reagent pump.
2. Remove 8 screws as shown in the photo on the next page. Please
note that two different sized screws are used. The five larger screws
go around the perimeter of the plastic frame.
3. Remove the entire chassis.
4. Replace the chassis and reverse the steps 1-3 above. Ensure
that the PCB is installed correctly in the enclosure before screwing
in place.
When properly located, the PCB and Chassis should have no wires or
tubing pushing against it.
