ORION 2C Manifold - Valve Adjustment Procedure

For UPS3110 Models with a Maximum Range 2000 PSI and below.

ORION 2C: Refer to “ORION 2C Valve Assembly Parts List” on page 45 and Figure 4-1 on the following
foldout 11 x 17 sheet.

Tools required:

Hex wrench (.050")

Snoop, leak gas detector (PN 64781)

NOTE: * denotes reference to Figure 2-2 on page 5.

1. If not already done, remove the ORION Input and Vent Valve Knobs (3) using the .061" hex wrench.
2. Energize the unit and let warm up. Turn

RANGE SELECT

(*6) to highest range. To adjust Input Valve, go

to step 3.

3. Check to see that the Knob Insert (4) is securely fastened to the Valve Shaft (11). If it is loose, re-tighten

the Set Screws (23) with the .061" hex wrench.

4. Using a .050" hex wrench, loosen the Set Screw (34) on the Locknut (2) and turn the Locknut clockwise

to its stop.

5. Close the

INPUT

Valve (*10) by turning the Knob Insert (4) clockwise until you feel the valve needle seat

on the O-ring (valve is now in closed position).

6. Rotate gears (6) on both Isolation valves, counter-clockwise until they stop, then rotate clockwise 1/2

turn (opening isolation valves).

7. Use the

PRESSURE LIMIT CONTROL

(*7), to increase the supply pressure to between 80% and 100% of

Full Scale.

8. 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).

9. 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.

10. Mark a radial line at the 12 o'clock position on the Knob Insert.
11. Turn the Knob Insert (4) clockwise to move the mark to the 6 o'clock position.

12. 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.

13. 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

14. 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).

INPUT

Valve by turning the Input knob (*10) clockwise.

18. Close the

VENT

Valve Knob Insert (4) clockwise until slightly snug.

19. With the supply pressure at 100% of Full Scale, open the

INPUT

Valve until the indicated pressure

stabilizes and then close the

INPUT

Valve.

20. 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.

21. Follow steps 10 through 15 replacing the term
