Safety Precautions Overspeed Adjustable Valve

Printed in USA November, 2011
Safety Precautions
IMPORTANT! Read this page before any work is performed on elevator equipment. The
procedures 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 factory wire connections
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 sum-
mary. See
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.

Electrical Safety Mainline Disconnect
Unless otherwise directed, always Turn OFF, Lock, and Tag out 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 Industry Field Employees’ Safety and Accident Prevention
Program Manual
for the required procedure.
Test Equipment Safety
Always refer to manufacturers’ instruction book for proper test equipment operation and adjust-
ments.
Megger or buzzer-type continuity testers can damage electronic components. Connection of
devices such as voltmeters on certain low level analog circuits may degrade electronic system per-
formance. 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 Industry Field Employees’ Safety Handbook for mechanical equipment safety
information on installation and service.

Static Protection Guidelines
IMPORTANT! 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, the factory bases warranty decisions on the
guidelines below.
Handling • Cards shipped from the factory 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 the factory must be packaged in a static bag designed for the card.
• Any card returned to the factory must be packaged in a shipping carton designed for the card.
• “Peanuts” and styrofoam are unacceptable packing materials.
Note: Refer to the
Vertical Express Replacement Parts Catalog to order extra static bags and
shipping cartons for each card.
Failure to adhere to the above guidelines will VOID the card warranty!

Installation
1. Install the valve within 12 inches of the jack(s) or the tee connecting multiple jacks. See Figure
1 or Figure 2 for proper orientation of the valve.
2. Turn the adjustment screw out (counterclockwise) to ensure that the valve does not set during
construction and adjustment of the control valve.
Note: This valve is directional. The jack must be connected to the outlet designated for the jack

Overspeed Adjustable Valve Adjustment
Printed in USA November, 2011 9
Adjustment
During this procedure, do not allow personnel to remain in the pit when the car is
running.
1. Verify that the job is complete and all of the cab weight is final.
2. Place a full load on the car.
3. Turn the adjustment screw on the valve clockwise a small amount and run the car down.
Repeat this process until the overspeed valve sets.
Note: During this procedure it may be necessary to make multiple down runs, especially if the
travel is short.
4. Turn the adjustment screw OUT (counterclockwise) one-half turn and tighten the locknut.
5. Run the car down from the top landing to the bottom landing at full speed to ensure that the
valve does not set with a full load and full travel.
6. Tighten the .375” nut against the sealing washer to seal the adjustment screw.
7. Drill the nut and install a lead seal.
