4.2.9 ORION 3A Manifold - Valve Adjustment Procedure
For UPS3110 5000 PSI and above Models.
ORION 3A: Refer to “ORION 3A Valve Assembly Parts List” on page 47 and Figure 4-2 on the second foldout
11 x 17 sheet.
Tools required: Hex wrench (.050")
Hex wrench (.061")
Snoop, leak gas detector (PN 64781)
NOTES: 1. * denotes reference to Figure 2-2 on page 5.
2. Customer must supply, as a minimum, input supply pressure with a supply gauge and pressure regulator.
1. Turn the supply pressure regulator off and vent manifold.
2. If not already done, remove the ORION
INPUT
and
VENT
Valve (outer) knobs (3) using the .061" hex
wrench.
3. Energize the unit and let warm up. Turn
RANGE SELECT
(*6) to highest range. To adjust
INPUT
Valve, go
to step 4.
4. Check to see that each knob insert (4) is securely fastened to the ORION input and vent valve shaft (11).
If it is loose, re-tighten the set screws (23) with the .061" hex wrench.
5. Using a .050" hex wrench, loosen the set screw (34) on each ORION input and vent valve locknut (2)
and turn each locknut clockwise to its stop.
6. Close the
INPUT
Valve by turning the Knob Insert (4) clockwise. until you feel the valve needle seat on
the O-ring (valve is now in closed position).
7. Rotate gears (6) on both Isolation valves, counter-clockwise until they stop, then rotate clockwise 1/2
turn (opening isolation valves).
8. Turn the supply pressure regulator to increase the supply pressure to between 80% and 100% of Full
Scale.
9. GAGE Model: Open the
VENT
Valve (*12) to atmosphere (rotate counter-clockwise), zero the indicator,
by momentarily pressing
ZERO
switch (*1), then close the
VENT
Valve (*12).
ABSOLUTE Model: Open the
VENT
Valve (*12) to atmosphere (rotate counter-clockwise), to release
line pressure, then close the
VENT
Valve (*12).
10. Slowly open the
INPUT
Valve by turning the Knob Insert (4) counter-clockwise until you notice the
displayed pressure increase. Then turn the Knob Insert slightly clockwise until the pressure stops rising.
11. Mark a radial line at the 12 o’clock position on the Knob Insert.
12. Turn the Knob Insert (4) clockwise to move the mark to the 6 o’clock position.
13. Turn the Locknut (2) counter-clockwise until it contacts the bottom of the stop washer (33). Tighten the
Set Screw (34) on the Locknut with the .050" hex wrench.
14. Install the
INPUT
Valve Knob (3) on the Knob Insert (4) and engage its Gear (5) with the smaller Isolation
Valve Gear (6). Turn the knob clockwise until the Isolation Valve is slightly snug.
CAUTION: DO NOT USE EXCESSIVE TORQUE WHEN DOING THIS, AS THE SEAT MAY BE DAMAGED
15. Remove the
INPUT
Valve Knob. Align the Set Screws (25) with the indentations on the Knob Insert.
Install the Knob on the Knob Insert while engaging the Knob Gear (5) with the Isolation Valve Gear (6).
16. Tighten the Set Screws (25) with the .061" hex wrench. The
INPUT
Valve is now adjusted.
17. To adjust the
VENT
Valve, follow steps 4 and 5.
18. Close the
INPUT
Valve by turning the Input knob (*10) clockwise.
19. Close the Vent Valve Knob Insert (4) clockwise until slightly snug.
20. With the supply pressure at 100% of Full Scale, open the
INPUT
Valve until the indicated pressure
stabilizes and then close the
INPUT
Valve.
21. Slowly turn the Vent Valve Knob Insert (4) counter-clockwise until the display starts to decrease, then
turn the Knob Insert (4) slightly clockwise until the indicated pressure stops decreasing.
22. Follow steps 11 through 15 replacing the term
INPUT
Valve with
VENT
Valve. The
VENT
Valve is now
adjusted.
