The auxiliary flow valve is fully open when 1/8 in. (3.2 mm) of screw head protrudes from regulator body. Do not open beyond this
point.
Series EA Regulator Installation
Place balancer on a clean, sturdy work surface with end cap upright. Pull out load wire rope until reel bottoms out. Remove EA control kit from
package. Check to ensure that O-ring is in port on back of regulator (1). Install regulator on end cap with four mounting screws and lockwashers
(2, 3 and 4). Connect control hose to port "A" on regulator and port on control handle.
Operational Adjustments EA Basic
● Prior to performing operational adjustments or servicing make sure air supply is off.
● Balancer may not support weight of empty handling device, or may raise device at a potentially hazardous rate. Extreme care must
be used until control adjustments are complete.
A minimum of 70 psi (4.8 bar) is required to operate the regulator. Do not use an air line lubricator.
1. Install regulator to balancer.
Auxiliary flow valve is fully open when 1/8 in. (3.2 mm) of screw head protrudes from regulator body. Do not open beyond this point.
2. Install EA pendant to "A" port of regulator.
3. Rotate control handle to HI-LOAD position.
4. Rotate regulator adjustment knob counterclockwise until 1/2 in. (13 mm) of thread is visible.
5. Rotate trim valve clockwise until snug, then counterclockwise 2 full turns.
6. Rotate auxiliary flow valve clockwise until snug.
7. Turn on main air supply. Adjust regulator to required air pressure.
8. Rotate adjustment knob clockwise slowly until the wire rope begins to raise, move to the full up position, ensure Z-Brake does not engage.
9. Install load hook and tooling or handling device to wire rope in the required position. Refer to "Lash-Up" Section on page 8.
10. Rotate both LO-LOAD and UN-LOAD flow controls clockwise until snug.
11. Apply the heaviest load to the tooling or handling device.
12. Rotate auxiliary flow valve clockwise until snug, then counterclockwise until 1/8 inch (3.2 mm) of screw head protrudes from side of
regulator body.
13. Rotate regulator adjustment knob clockwise until load is balanced.
14. Lift and lower load several times. Equal effort should be required to raise and lower load. If load is hard to pull down turn trim valve
clockwise 1/2 turn and check. If load is hard to raise turn trim valve counterclockwise 1/2 turn and check.
15. Rotate pendant to LO-LOAD position.
16. Slowly rotate LO-LOAD flow control counterclockwise until load drifts to the floor or full down position. The wire rope should go slack.
17. Remove heaviest load from tooling or handling device.
18. Apply medium weight load to tooling or handling device.
19. Rotate LO-LOAD flow control clockwise until load is balanced.
20. Tighten jam nut to maintain proper setting.
21. Lift load to full up position.
22. Rotate pendant to UN-LOAD position.
23. Slowly rotate UN-LOAD flow control counterclockwise until load drifts to the floor or full down position. Allow wire rope to go slack.
24. Remove medium weight load from tooling or handling device.
25. Rotate UN-LOAD flow control clockwise until tooling or handling device is balanced.
26. Maneuver tooling or handling device to heaviest load and engage load.
27. Rotate pendant to HI-LOAD position.
28. The load should be in balance.
29. Set down the heaviest load and rotate pendant to UN-LOAD position.
30. Maneuver tooling or handling device to medium weight load and engage load.
31. Rotate pendant to LO-LOAD position.
32. The load should be in balance.
33. Set down medium load and rotate pendant to UN-LOAD position.
If, for any reason, the pilot regulator must be readjusted, the needle valves will have to be adjusted also.
Operational Adjustments EA 2PS
Refer to Dwg. MHP1915 in the Parts Information Manual.
The balancer may not support the weight of the empty handling device, or may raise device at a potentially hazardous rate. Extreme
care must be used until control adjustments are complete.
