Safety Precautions

Read this page before any work is performed on elevator equipment. The pro-

cedures contained in this manual are intended for the use of qualified elevator

personnel. In the interest of your personal safety and the safety of others, do

not attempt any procedure that you are not qualified to perform.

All procedures must be accomplished in accordance with the applicable rules in the

latest edition of the National Electrical Code, the latest edition of ASME A17.1, and

any governing local codes.

Terms in This Manual

CAUTION statements identify conditions that may result in damage to the

equipment or other property if improper procedures are followed.

WARNING statements identify conditions that may result in personal injury if

improper procedures are followed.

General Safety

Before applying power to the controller, check that all manufacturing wire con-

nections are tight on relays, contactors, fuse blocks, resistors, and terminals on

cards and DIN rail terminals. Connections loosened during shipment may

cause damage or intermittent operation.

Other specific warnings and cautions are found where applicable and do not appear in this

summary. See the

Elevator Employee Safety and Accident Prevention Program Manual

and the

Elevator Industry Field Employees’ Safety Handbook

for electrical equipment

safety information on installation and service.

Electrical Safety All wiring must be in accordance with the National Electrical Code and be consistent with

all state and local codes.

Use the Proper Fuse To avoid fire hazards, use only a fuse of the correct type, voltage, and current rating. See

the job specific drawings sheet (Power Supplies) for fusing information.

Electric shocks can cause personal injury or loss of life. Circuit breakers, switches, and

fuses may not disconnect all power to the equipment. Always refer to the wiring diagrams.

Whether the AC supply is grounded or not, high voltage will be present at many points.

Printed Circuit Cards Printed circuit boards may be damaged if removed or installed in the circuit while applying

power. Before installation and/or removing printed circuit boards, secure all power. Always

store and ship printed circuit cards in separate static bags.

Mainline Disconnect Unless otherwise directed, always Turn OFF, Lockout, and Tagout the mainline disconnect

to remove power from elevator equipment. Before proceeding, confirm that the equipment

is de-energized with a volt meter. Refer to the

Elevator Employees’ Safety and Accident

Prevention Program Manual

for the required procedure.

Electrical Safety

(continued)

Test Equipment Safety Always refer tomanufacturers’ instruction book for proper test equipment operation

and adjustments.

Megger or buzzer-type continuity testers candamage electronic components. Connection

of devices such as voltmeters on certain low level analog circuits may degrade electronic

system performance. Always use a voltmeter with a minimum impedance of 1M Ohm/Volt.

A digital voltmeter is recommended.

When Power Is On To avoid personal injury, do not touch exposed electrical connections or components while

power is ON.

Mechanical Safety

See the

Elevator Employees’ Safety and Accident Prevention Program Manual

and the

Ele-

vator Industry Field Employees’ Safety Handbook

for mechanical equipment safety infor-

mation on installation and service.

Arrival of Equipment

Receiving Upon arrival of the equipment, inspect it for damage. Promptly report all visible damage to

the carrier. All shipping damage claims must be filed with the carrier.

Storing During storage in a warehouse or on the elevator job site, precautions should be taken to

protect the equipment from dust, dirt, moisture, and temperature extremes.

Asbestos Compliance

Vertical Express elevator personnel will no longer drill or modify any doors with asbestos

containing materials (ACM) or possible asbestos containing materials (PACM). All elevator

doors manufactured or installed 1980 and earlier will be treated as having ACM/PACM.

Doors with ACM/PACM should be replaced rather than modified. If replacement is not fea-

sible, abatement modifications shall be done by a licensed asbestos abatement company.

Vertical Express mechanics will safely stage the equipment for the abatement team, or

remove the doors and seal them with plastic for delivery or pick up by the asbestos abate-

ment company.

Doors manufactured or installed 1980 and earlier may be modified by Vertical Express

employees if a test is conducted by a licensed asbestos company prior to work showing

zero evidence of ACM/PACM.

All employees that risk exposure to asbestos will complete Vertical Express safety depart-

ment approved asbestos awareness training.

All employees will stop any work that could expose them to ACM/PACM, and immediately

contact their supervisor and their safety manager. All exceptions must be approved by the

Director of Health and Safety.

Static Protection Guidelines

Read this page before working with electronic circuit boards.

Elevator control systems use a number of electronic cards to control various functions of

the elevator. These cards have components that are extremely sensitive to static electricity

and are susceptible to damage by static discharge.

Immediate and long-term operation of an electronic-based system depends upon the

proper handling and shipping of its cards. For this reason, Manufacturing bases warranty

decisions on the guidelines below.

Handling • Cards shipped from Manufacturing in separate static bags must remain in the

bags until time for installation.

• Anti-static protection devices, such as wrist straps with ground wire, are required

when handling circuit boards.

• Cards must not be placed on any surface without adequate static protection.

• Only handle circuit cards by their edges, and only after discharging personal

static electricity to a grounding source. Do NOT touch the components or

traces on the circuit card.

• Extra care must be taken when handling individual, discrete components such as

EPROMS (which do not have circuit card traces and components for suppression).

Shipping • Complete the included board discrepancy sheet.

• Any card returned to Manufacturing must be packaged in a static bag designed

for the card.

• Any card returned to Manufacturing must be packaged in a shipping carton

designed for the card.

• “Peanuts” and Styrofoam are unacceptable packing materials.

Failure to adhere to the above guidelines will void the card warranty!

I-2 / I-3 Valve Preliminary Settings

August 2019 - 89130 v.3.0 7

Preliminary Settings

Oil Viscosity and Viscosity Control

Use extreme caution when making adjustments near moving belts. When operat-

ing the elevator from the controller, follow all safety precautions.

• Verify that the power unit is in a ventilated room that remains between 50°F and 90°F.

• Adjust the valve when the oil is at its operating temperature of 100°F to 170°F.

• Check the unit performance when the oil temperature is no less than 100°F.

• Changes in oil temperature cause changes in valve behavior.

Relief Pressure Setting

The I-2/I-3 Valve requires a minimum static system pressure of 90 PSI.

1. Ensure that the car is empty.

2. Turn OFF, Lockout, and Tagout the mainline disconnect.

3. Open the manual lowering valve to lower the car onto the buffers. See Figure 1.

4. Close the manual lowering valve.

5. Install a pressure gauge on the quick connector located on the far side of the valve.

6. Turn the relief pressure adjustment screw OUT until 5/8" extends beyond the relief

assembly housing, and then tighten the locknut.

2. Turn the low pressure adjustment screw IN by hand until it touches the regulator piston.

3. Turn the up leveling adjustment screw OUT until it stops.

4. Turn the up leveling adjustment screw IN 4 turns.

Adjustment Needles

To make adjustments, do not loosen the nuts on the adjustment needle stems. The nuts

must be snug against the valve body at all times.

1. Turn the up start, up stop, and up slowdown adjustments IN to the fully closed position.

See Figure 2.

2. Turn the up start adjustment OUT 9 turns.

3. Turn the up stop adjustment OUT 3 turns.

4. Verify that the up slowdown adjustment remains closed.
