1. Install regulator and 2PS valve to balancer.
2. Rotate regulator adjustment knob counterclockwise until 1/2 in. (13 mm) of thread is visible.
3. Rotate trim valve clockwise until snug, then counterclockwise 2 full turns.
4. Rotate auxiliary flow valve clockwise until snug, then counterclockwise until 1/8 in. (3.2 mm) of screw head protrudes from side of regulator
body.
5. Rotate 2PS-flow control clockwise until snug, then counterclockwise 1 turn.
6. Ensure tube is connected at the 2PS valve and handling device.
7. Turn on main air supply. Adjust regulator to required air pressure.
8. Rotate adjustment knob clockwise slowly until wire rope begins to raise, move to the full up position, ensure the Z-Brake does not engage.
9. Install load hook and tooling or handling device to wire rope in required position. Refer to "Lash- Up" Section on on page 8.
10. Engage load with tooling or handling device.
11. Rotate regulator adjustment knob clockwise until load is balanced.
12. 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.
13. Lower part to set down position. Rotate 2PS-flow control counterclockwise one full turn. Tooling or handling device may raise or lower
unexpectedly when part is released. Ensure you are clear of the vertical path at all times during adjustments.
14. Release part from tooling or handling device. Rotate 2PS-flow control counterclockwise if tooling or handling device raises or
ounterclockwise if it lowers until tooling or handling device is balanced.
15. Lift and lower load several times. Equal effort should be required to raise and lower load. If load is hard to pull down, turn 2PS-flow control
counterclockwise 1/2 turn and check. If load is hard to raise turn trim valve clockwise 1/2 turn and check.
16. Engage and disengage the part checking the balance condition of both the loaded and unloaded tooling or handling device.
Tandem Control Balancer
Tandem Control Installation
Refer to Dwg. MHP1923 in the Parts Information Manual
1. Install master manifold (1) behind EA, ZA or BA control kit.
2. Install slave manifold (2) to second balancer.
3. Install tandem hose assembly (10) between master (1) and slave (2) manifolds.
Interlock Adjustments
Refer to Dwg. MHP1920 in the Parts Information Manual.
1. Raise handling device/fixture to a mid travel position, so balancer is supporting the entire weight. The Interlock screw threads into the
aluminum housing that will rotate with the screw. Hold aluminum housing while turning the screw.
2. Turn screw counterclockwise until interlock light illuminates (green light) or until 1-1/2 in. (38 mm) of thread is visible.
3. Depress and release (repeatedly) the clamp/vacuum release button while rotating Interlock screw clockwise until clamp opens or blow off
air is heard at vacuum cups or interlock indicator extinguishes.
4. Raise and lower handling device/fixture several times. Check for proper operation of clamp and vacuum controls.
5. Raise handling device/fixture to the full up position.
6. Depress and hold up lever of the ZA control for three seconds. This will simulate an additional load on the balancer.
7. Depress and release clamp/vacuum release button. Clamp should remain closed or not blow off air to vacuum cups.
8. Check that interlock indicator has illuminated (green light).
9. Lower handling device/fixture and engage a part with the end effector.
10. Raise load 1 in. (26 mm) above pick up point.
11. Depress and release clamp/vacuum release button. Part should remain attached to end effector.
12. Lower handling device/fixture and release part at the pick up point.
13. Hold aluminum housing and tighten jam nut on Interlock screw to prevent setting from changing.
Load Hooks, Lash-Up And Yarding
Lash-Up
To properly install load hook to wire rope you must determine the following:
Refer Dwg. MHP1358 on page 14, A. Obstruction.
Refer Dwg. MHP1924 on page 14, A. Load.
1. Highest point which load must clear from floor.
2. Distance from hook throat to bottom of load.
3. Add number 1 dimension to number 2 dimension, then add 3-1/2 in. (89 mm).
4. Measuring from the floor with the wire rope fully retracted, install hook using the dimension from number 3 to the floor.
5. Verify coverage is correct. Use wire cutter part number 01942 to remove excess wire rope.
● Do not operate balancer if load is not centered under wire rope. Yarding of the wire rope will cause premature wire rope failure and
undue wear of internal balancer parts and may void warranty.
● Do not continuously rotate balancer in one direction. Air line damage will occur from continuous rotation potentially allowing the
load to lower. Reverse direction with each cycle of the balancer to prevent twisting and damage to air lines.
Yarding
Wire rope should not be yarded more than 10 degrees from vertical center line of wire rope guide. Excessive Yarding will cause increased wear
on balancer and decrease working life of components.
