3.1 Control Valve
The River Line Control Valve has 3 positions:
“Open” In the Open position, the bubbler (regulator) is open to the River Line port and the
transducer.
“Close” In the Close position, the bubbler (regulator) is closed to the River Line. (If there is nothing
plugged into the Test Port Quick Connect, the transducer pressure will continue to increase
very slowly as the regulator reacts to a closed system –
DO NOT leave it in this position for
extended periods as the internal pressure build up may exceed the burst pressure of the
transducer element !!!!)
Note : The cabinet door has an interlock that prevents the door from
being closed while the valve is in the “Close” position.
“Purge” In the Purge position, the receiver tank is directly connected to the River Line port to allow a
Purge of the River Line. After a River Line Purge is performed, rotate the control valve back
to the Close position and wait until the River Line pressure drops to a normal level (say 10
seconds) before rotating the control valve back to the Open position. (Otherwise the Purge
pressure may be introduced to the transducer and cause damage!!!)
IMPORTANT: When purging, STOP when the tank pressure falls below 400kPa, otherwise the river-line pressure may fall
below the water head pressure resulting in water entering the River Line!
3.2 Startup Sequence
After power is first applied, the compressor will turn on if the tank pressure is below 400 kPa.
3.3 Tank Pressurisation & Mist Separator Flushing
When the tank pressure falls below 400kPa (58psi) [±20%], the Condor pressure switch will close, causing the controller
to turn on the compressor and then pump the pressure back up to 750kPa (110psi) [±20%].
