Trifecta 2K
(10) The Trifecta can now be powered up. The controller will display Trifecta followed by the
part number of the software (currently this part number should be 11190217). The controller
will then choose the cylinder with the least amount of liquid in it for use. It should not be in a
fill mode at this time. If the unit is in a fill mode, the controller cannot be accessed. To access
the controller data, press the menu key. You should be at the operating pressure. The controller
will have an operating pressure of 425 psi (29.3 bar) as default setting. This can be lowered to
the desired pressure at this time. This is accomplished by using the up and down arrow keys.
Always set the operating pressure to the lowest setting desired for the application. The F1 key
will scroll you through the menu. The liquid levels will be displayed as will also the cylinder
pressures and the bulk tank pressure. These values are for information and are not adjustable.
You will also be offered in the menu a choice between 2K or 10K size. Choose the size of the
Trifecta you have. The setting for overpressure will have default setting of 480 psi (33.1 bar).
This setting should always have at least a 55-psi (3.8 bar) differential between it and the
operating pressure. (Operating pressure at 425 (29.3 bar), overpressure at 480 (33.1 bar).) Bulk
tank critical should be set to 150 psi (10.3 bar). To exit the menu, press menu and the
controller will again be in the run mode. (Remember when you access the menu, all solenoid
valves close, interrupting any process in use.)
(11) Bleed off product after the vaporizer until the cylinder in use begins a fill mode. Watch the
fill mode to ensure the system functions. When the fill mode is complete, bleed product off to
empty the second cylinder and watch its fill mode. Remember the bulk tank critical will
determine if the cylinders vent to bulk or vent to atmosphere during filling. When the second
cylinder is full, a complete cycle has taken place and both cylinder will be full.
(12) The overpressure setting should be tested at this time. This is done by manually raising the
cylinder pressures with the system on. When you exceed the overpressure, the cylinder should
vent to bulk or atmosphere depending upon the bulk tank pressure. If the cylinder relief valves
open prior to the overpressure, the relief valves may need replacing due to weak springs.
(13) The system should now be ready for use.
Control Panel Heater
The T
RIFECTA
control panel is equipped with heater system to maintain a minimum
temperature during extremely cold conditions. The setting should be set to about 25
o
F (-3.9
o
C).
