how to install the new chip. Plugging the EPROM chip in upside-down
may damage the chip. Static electricity can damage the EPROM, so
avoid touching the pins on the chip, and ground yourself (by touching
the controller cabinet) before touching the chip or the controller. Do
not expose the EPROM program chip to bright light, and do not
remove the label over the EPROM program chip window.
WARNING: The elevator controller must be installed by experienced
field installation personnel. The field installation personnel must
know and follow all the rules and regulations pertaining to the safe
installation and running of elevators. Additional information for
specific devices (such as the valves, door operator, etc.) is the
responsibility of the manufacturers of those devices.
WARNING: This equipment is designed and built to comply with ANSI
A17.1, ASME A17.5 and CAN/CSA B44.1 and must be installed by a
qualified contractor. It is the responsibility of the contractor to make
sure that the final installation complies with all applicable local, state
and national codes, and is installed safely.

Virginia Controls, LLC MH-3000 User Manual, 1_03C10-VC Page 7
WARNING: The 3 phase AC power supply to this equipment must
come from a fused disconnect switch or circuit breaker which is sized
in accordance with all applicable national, state and local electrical
codes, in order to provide the necessary branch circuit protection for
the controller and motor. Incorrect motor branch circuit protection
may create a hazardous condition.
WARNING: Proper grounding is vital for the safe operation of your
system. Bring the ground wire to the ground stud that is labeled
"GND" or "G". You must choose the proper conductor size. See
national electrical code article 250-95, or the related local applicable

2. Controller Installation and Wiring
2.1 Controller Installation
2.1.1 Controller Location Selection and Environment
Mount the controller in a location that provides:
•adequate support for the weight of the controller,
•adequate lighting for installation and maintenance,
•convenient access for the routing of required conduits and cables,
•convenient access to other devices in the machine room,
•a minimum of vibration (supply additional bracing or reinforcement if required).
For improved controller reliability:
•Keep the machine room clean.
•Do not install the controller in a dusty area.
•Do not install the controller in a carpeted area, or area where static electricity is a
problem.
•Keep room temperature between 0C to 50C (32F to 122F), and 95% non-
condensing relative humidity. Extended high temperatures will shorten the life of
electronic components. Provide adequate ventilation or air-conditioning as required
if necessary.
•Avoid condensation on the equipment. Keep the controller away from sources of
condensation and water (such as open windows) as these can create a hazardous
condition and can damage the equipment.
•Do not install the controller in a hazardous location and where excessive amounts of
vapors or chemical fumes may be present. A NEMA 4 or NEMA 12 rated enclosure
can be provided if necessary.
•Make sure power line fluctuations are within 10%.
•High levels of radio frequency emissions may cause interference with the controller
microprocessor, and produce unexpected results. This could be caused by hand-held
communications devices used near the controller.
•Long term operation of the controller without the door or cover in place is not
recommended.

Virginia Controls, LLC MH-3000 User Manual, 1_03C10-VC Page 9
2.1.2 Controller Grounding
Grounding of the controller must conform to all applicable codes. Proper
grounding is essential to the safe operation of the equipment. It will also reduce
the likelihood of noise-induced problems, which could include CPU crashes, or I/O
communication errors.
•The grounding wire should be sized per the applicable codes.
•Connect the ground to a good building ground, such as the structural steel of
the building, or a cold water pipe.
2.2 Car and Hoistway Wiring
Review the schematics and field wiring diagrams before attempting to hook up the
controller.
2.2.1 Floor Switches
The Floor Switches, if used, are normally open contacts that should close under each of
the following conditions:
1. the car is at the slowdown point above the floor, OR
2. the car is at the slowdown point below the floor, OR
3. the car is at the floor (optional), OR
4. the car is between the up and down slowdown points of that landing (optional).
Conditions (1) and (2) are required to change the floor relays and initiate slowdown.
Condition (3) is required at the terminal landings, but is optional at the intermediate landings.
Condition (4) is optional.
There are many acceptable methods of providing the floor switch signals, such as by
having a single Floor Switch at floor level, and an adjustable length cam on the car, or by
having two Floor Switches per floor, and a fixed length cam on the car. The Floor Switches
may be mounted on the car if they are in separate rows. It is recommended that the method
used allow for separate adjustment of the up and down slowdown distances.
NOTE: Recommended slowdown distance is about 6" for every 25fpm of car
speed, for speeds of up to 200fpm. Minimum recommended target length for
the floor switches is 1".
If there are short floors, refer to the schematic for special instructions, if required.
NOTE: The terminal landing Floor Switches must be maintained while the car
is within door zone of the terminal landing.

Virginia Controls, LLC MH-3000 User Manual, 1_03C10-VC Page 10
2.2.2 Car Top Selector
The pulsing-type Car Top Selector provides Floor Change/Slowdown signals and Leveling
signals, as shown on the car top selector sheet in the schematic. The signals should be a
normally open contact that closes as described below.
1. UP SLOWDOWN closes at the Slowdown distance below the floor.
2. DOWN SLOWDOWN closes at the Slowdown distance above the floor.
3. UP and DOWN LEVEL, and DOOR ZONE/LOW LEVEL. (See "Leveling Sws")
NOTE: Recommended slowdown distance is about 6" for every 25fpm of car
speed, for speeds of up to 200fpm. Minimum recommended target length for
the floor switches is 1".
An extra reset target is required at each terminal landing, as shown on the
schematic, so that the Up Slowdown Switch is closed when the car is in the leveling
zone at the top landing, and the Down Slowdown Switch is closed when the car is in
the leveling zone at the bottom landing. These targets are used to reset the floor
position at the terminal landings.
2.2.3 Leveling Switches
The Up Level Switch is a normally open contact that closes when the car is in the leveling
zone below the floor, and the Down Level Switch is a normally open contact that closes when
the car is in the leveling zone above the floor. Adjust the distance between the Up Level
Switch and the Down Level Switch to be equal to the length of the leveling vane/target plus
the desired Dead Zone distance (usually 1/4" to 1/2"). The actual length of the leveling
target is not critical (except in some short floor situations) and is usually 6-10". Position the
leveling vane/target so that when the car is floor level the Up and Down Leveling Switches are
centered around the vane/target, and both switches are open.
The Door Zone Switch is a switch (or switches) activated by the leveling vane/target when
the car is within 3" of floor level. If the leveling vane/target is 6" long, then only one switch is
required, mounted between the Up and Down Leveling Switches, otherwise two switches
wired in series should be provided.
2.2.4 Terminal Landing Normal Slowdown Switches
The Terminal Landing Normal Slowdown Limit Switch is a normally closed contact that
opens when the car is closer to a terminal landing than the minimum slowdown distance. It
will prevent the car from running into the terminal landing at full speed. It should be adjusted
to open approximately one inch beyond the point where the normal slowdown (from the floor
switches or the car top selector) is initiated.
2.2.5 Terminal Landing Normal Limit Switches
The Terminal Landing Normal Limit Switch (sometimes called a Directional Limit
Switch) is a normally closed contact that opens when the car has traveled 1" past
floor level at a terminal landing. The car should not be on the Terminal Landing
Normal Limit Switch when the car is floor level at the terminal landing. The Limit

Virginia Controls, LLC MH-3000 User Manual, 1_03C10-VC Page 11
Switch will prevent the car from traveling further away from the normal area of car travel, but
allows the car to run back towards the normal area of car travel.
2.2.6 Terminal Landing Final Limit Switches
The Terminal Landing Final Limit Switch, where required by code, is a normally closed
contact that opens when the car has gone a considerable distance beyond floor level at a
terminal landing. It will prevent any further movement of the car in either direction. Consult
the applicable codes for the proper setting of this switch.
2.2.7 Emergency Terminal Landing Limit Switch
The Emergency Terminal Landing Slowdown Switch should be installed as required by the
applicable codes. It is a normally closed contact that opens after the car has gone beyond
the Terminal Landing Normal Limit Switch.
2.2.8 Hoistway Access Zone Switches
The Hoistway Access Limit Switches limit the motion of the car on Hoistway Access, by
disabling the car if it moves away from the access floor. Install the zone switches to stop
the car from running down if the top of the car goes below floor level at the top access floor,
and to stop the car from running up if the car goes above the second floor while on
Hoistway Access at the bottom floor.
2.2.9 Door Open and Close Limit Switches
The Door Open Limit Switch is open when the doors are fully open, and closed at all other
times. It will de-energize the door open relays in the door operator when the doors have
opened fully.
The Door Close limit Switch is open when the doors are fully closed, and closed at all other
times. It will de-energize the door close relays in the door operator when the doors have
closed fully.
NOTE: Many problems in operation can be attributed to failures in the Door
Open or Close Limit Switches (including long door times, improper door
operation on Fire Service, inability to go on to or to clear Fire Service, etc.)
Always check the Door Open and Close Limit Switches if unusual operation of
the elevator is observed.
NOTE: It is recommended that the Door Close Limit Switch be adjusted so
that, as the doors are closing, the Car Door Contact closes before the Door
Close Limit opens. Consult the Door Operator Manufacturer's installation
instructions for further details on the adjustment of the doors.
NOTE: 2000 (or later) code compliant controllers will not run without the
Door Close Limit operation properly.
NOTE: If a solid state door operator unit is being used, check the appropriate
schematics to see if any changes are required on the actual operator. These
may include changing resistors in the operator, and adding a diode for proper
open and close torque.

Virginia Controls, LLC MH-3000 User Manual, 1_03C10-VC Page 12
2.3 Machine Room Wiring
Mount the controller firmly and install all required conduits before wiring the controller.
Note where duct has been provided in the controller for customer access, before deciding
where to locate conduit openings.
WARNING: Do not allow any metal shavings to get into relays or
contactors, or in or behind the electronic components, as these could
cause serious damage to personnel or the equipment.
2.3.1 Incoming Power
WARNING: THE 3 PHASE AC POWER SUPPLY TO THIS EQUIPMENT
MUST COME FROM A FUSED DISCONNECT SWITCH OR CIRCUIT
BREAKER WHICH IS SIZED IN ACCORDANCE WITH ALL APPLICABLE
NATIONAL, STATE AND LOCAL ELECTRICAL CODES, IN ORDER TO
PROVIDE THE NECESSARY BRANCH CIRCUIT PROTECTION FOR THE
CONTROLLER AND MOTOR. INCORRECT MOTOR BRANCH CIRCUIT
PROTECTION MAY CREATE A HAZARDOUS CONDITION.
Incoming AC power wiring should be done by a qualified and licensed electrician, using
the appropriate size wires for the installation. Consider the motor size and type of starter,
and also the length of wire required from the main power distribution center in determining
the proper wire size.
Proper branch circuit protection and disconnect device(s) must be provided, as required
by applicable local, state and national codes.
2.3.2 Grounding
WARNING: PROPER GROUNDING IS VITAL FOR THE SAFE
OPERATION OF YOUR SYSTEM. BRING THE GROUND WIRE TO THE
GROUND STUD THAT IS LABELED "GND" OR "G". YOU MUST CHOOSE
THE PROPER CONDUCTOR SIZE AND MINIMIZE THE RESISTANCE TO
GROUND BY USING SHORTEST POSSIBLE ROUTING. SEE NATIONAL
ELECTRICAL CODE ARTICLE 250-95, OR THE RELATED LOCAL
APPLICABLE CODE.
Proper grounding is vital for the safe operation of your system, and will also
reduce the likelihood of noise-induced problems, which could include CPU crashes,
or I/O communication errors.
•The grounding wire should be sized per the applicable codes.
•Connect the ground to a good building ground, such as the structural steel of the
building, or a cold water pipe.
•Connect the ground on the controller to the stud labeled "GND" or the terminal "G",
as shown on the controller schematic.

Virginia Controls, LLC MH-3000 User Manual, 1_03C10-VC Page 13
2.3.3 Pump Motor Wiring
Connect the pump motor as shown on sheet S of the schematic.
If an Across-the-Line starter is used, then the motor leads will connect to the starter
overload.
If a Wye-Delta starter is used, then the motor leads will connect to the bottom of the
overload, and to terminals T4,T5,T6. See the schematic for specific connection details.
2.3.4 Wye-Delta Run Contact Wiring
If a Wye-Delta starter is used, an auxiliary contact of the RU contactor may be connected
in series with the up valves, to prevent the car from starting to run up until the motor is in
the Delta mode. If this is not desired, then jump the contact. This will allow the valves to
be energized as soon as the pump motor starts.
If a Soft-Start is used, the Up-to-Speed signal is used in a similar way.

Virginia Controls, LLC MH-3000 User Manual, 1_03C10-VC Page 14
3. Start-Up Instructions
If it is desired to run the car temporarily, during construction, refer to the Temporary
Run Connections section. Otherwise proceed through each of these steps and checks before
applying power.
3.1 Before Applying Power
The system has been programmed and tested for the specific elevator system. Refer to
the MH-3000 Setting sheet in the as-built schematic for default factory settings and
features.
3.1.1 Power and Grounding
WARNING: Confirm that the voltage of the incoming power matches
the controller before applying power to the controller.
Check the system for improper grounds before applying power to the controller.
With the power off, remove the fuses from the secondary of the main control circuit
transformer ("CCXF"). Check the safety circuit (terminals 1 through 6, and 14, 16, 18, 19)
for grounds.
NOTE: A meter will read a short through the windings of the main control
circuit transformer and/or any power supplies.
With the fuses still removed, apply power to the controller, and verify that the voltage at
the secondary of the main control circuit transformer ("CCXF") is 110-125VAC.
3.1.2 Input/Output Wiring
NOTE: The input/output boards are equipped with quick disconnect terminal
blocks. During the initial installation, you may want to remove the terminal
blocks, hook up your field wires to the terminal blocks, test the field wiring for
no shorts to ground or hot (terminal 1) before plugging these terminals back
into the I/O boards.
With the power off, and the fuses removed, check each input point for grounds, as
described in the section Power and Grounding. If a ground is observed, check the
schematic to determine if this is correct (it usually is NOT!).
With the power off check each output for grounds, also check for shorts to the hot side
(terminal 1). Note that some field devices, such as buzzers, will have very low resistance.
WARNING: Each output point should be isolated from ground and the
hot side.

Virginia Controls, LLC MH-3000 User Manual, 1_03C10-VC Page 15
3.2 Applying Power
Remove all fuses before applying power. Reinsert the fuses, one circuit at a time,
checking each circuit before adding the next.
It is recommended that you start up the controller in Inspection mode, which can be
done by opening the Inspection Switch, or removing the field wire(s) from terminal 23.
WARNING: The field wire in terminal 23 is HOT. If it is removed,
make sure it is insulated and labeled. Reconnect it when the car is to
be taken off Inspection Operation.
3.2.1 Motor Rotation
Check that the motor is rotating in the proper direction by turning on the power, then
briefly pushing in the motor starter ("PM" on across-the-line installations, "STR" on Wye-
Delta installations). Observe the direction of rotation of the motor, and if it is incorrect,
reverse any two of the main power leads at the main line disconnect.
If a Reverse Phase relay is provided, check that the OK light is on when power is applied
to it. If it is not, then reverse any on the two wires connected to the A,B,C terminals.
3.3 Temporary Run Connections
To run the car on temporary service before the controller is fully installed, see the
MH3000 Temporary Run Manual.

Virginia Controls, LLC MH-3000 User Manual, 1_03C10-VC Page 16
4. Final Adjustments
When the controller is ready to be run in automatic, it is recommended that EITHER a
factory reset be performed OR the values of the settings and features be verified. If the
program is custom (the job number will be in the bottom line of the banner) then a factory
reset is recommended. If the job is not custom (the bottom line of the banner will start
with a letter), all the values and settings for the job must be re-entered if a factory reset is
done. Refer to the section Reset Settings, or the Frequently Asked Question - How Do I
Reset All Settings and Features Back to the Original Values.
A factory reset can be done by:
1. Turning off the power;
2. Put the car on inspection;
3. Jump terminals 1 to 21 and 1 to 22;
4. Turn on the power for 15 seconds;
5. Turn off the power, and remove the jumpers, and continue as normal.
Alternatively, the keypad can be used. Press Nxt until the menu item "Go to Setup
Menu" is displayed, then press Ent 3 times. (The screen will show a warning, then go to
the Setup Menu, where the first item is Reset (factory) Settings). The password “911”
should be entered when requested. Press Esc to return the elevator to service.
As the wiring is completed, the following modes of operation can be checked and used.
4.1 Inspection Operation
To run the car on Inspection Operation, the safety string (including the door contacts,
terminal landing normal slowdowns, normals and finals) should be operational.
The Doors Closed and Gate Closed inputs on the I/O board should be on.
The Inspection Input should be de-energized.
Pressing the Up Run and Run (or Enable) Buttons will cause the Up Direction output to
come on.
If the Doors Closed input is on, the Up Run outputs for the motor and the valves will
energize, and the car will run up.
(Down direction is similar)
NOTE: If Hoistway Access is used to get on top of the car, then the doors will
be open when Top of Car Inspection is initiated. In this case, the doors will
close when the Up (or Down) Run and Run (or Enable) buttons are pressed.
If it is required that the doors should only operate manually on Inspection,
then the Bit Feature to “Disable Door Close on Inspection” should be enabled.
In this case the doors must be closed manually or by means of the Door Close
button on the Door Operator (if provided).

NOTE: If 2000 (or later) Code and the MH5 board is provided, then the
controller is expecting terminal 3 to go low when the Inspection Run Buttons
are not being pressed. If a temporary run station is being used that is not
wired as shown on the schematics, then the controller will show a fault if
terminal 3 does not go low when the car stops. The redundancy fault can be
temporarily defeated by turning Switch 3 on the CPU Slide Switch S2 to the
ON position. This will also turn on the Fire Buzzer output, as a reminder to
turn off the defeat when the car is ready for full operation.
4.2 Floor Position and Slowdown
The program is in EPROM (Electrically Programmable Read Only Memory). The floor
relays and fire service relays are maintained in the microprocessor RAM memory and are
held through power loss by a battery on the CPU board. The floor relays may need to be
reset when the controller is initially installed. This will be accomplished when the elevator
hits any floor switch. With a pulsing type selector, the floor position is reset at either
terminal landing when a slowdown switch and a leveling switch are energized at the same
time.
NOTE: If floor switches are used, they should be maintained at the terminal
landings, so that they are energized whenever the car is in the slowdown
zone at that landing.
Make your final adjustments for the slowdown targets. All slowdown distances should be
equal.
If a pulsing selector arrangement is used, remember to install the reset targets at the
terminal landings.
4.3 Position Indicators
Verify that the floor position changes properly as the car goes past each landing. Floor
change should take place at the slowdown point before each landing.
If the Position Indicator does not match the actual car position, run the car to a terminal
landing reset target (with pulsing selector only).
4.4 Independent Service
Independent Service is useful for final tune-up of the car. Initiate Independent Service
by turning on the Independent Service Switch in the car, or by jumping the Independent
Service Switch input.
On Independent Service, the hall calls will be canceled. The car will run from car calls
only, and will park with the doors open. To close the doors, jump terminal 1 to terminal 28
("Door Close Button" input). This jumper may be left on, if desired, so that the car may be
run by jumping the desired car call input.

NOTE: To run the car from the machine room, without the doors opening,
turn off the DOL Cutout Switch located on the MH4 or MH5 printed circuit
board. This will de-energize the Door Open Limit Sw Input, and prevent the
doors from opening.
NOTE: If the car does not run, verify that no door protective device (Door
Open Button, Safety Edge, Electric Eye, Infra-red Curtain) is holding the
doors open. Verify that the car is not stuck in leveling. Verify that the Door
Contacts input is energized and the Door Close Limit input is de-energized.
4.5 Car and Hall Calls
To observe the operation of the car and hall calls, the system must be in automatic
operation (LED D1 on the CPU board should be on.) Verify that all car and hall calls work.
NOTE: On DUPLEX systems the doors must be allowed to operate for the
calls to be canceled properly.
Each call will be canceled when the car initiates slowdown for the call, or when the doors
start to re-open for the call if the car is already at the floor.
If both hall calls are entered at an intermediate landing, and no other calls are in the
system, the doors will close after answering one of the calls, then re-open in response to
the other call.
4.6 Door Operation
Verify that any required changes to the door operator, as shown on the door operator
drawings, have been made correctly.
Check the Door Open and Close Limits for proper operation.
If the doors attempt to open for too long, the open cycle will be stopped. The car will
then respond to other calls, and try to open the doors again.
If the doors fail to close properly within a preset time, the doors will re-open, and try to
close again. If the doors closed, but the car does not run in response to a call, the doors
will re-cycle, and the car will try again.
For very slow doors, the Door Stuck Timer, which initiates the Door Open and Door Close
Fail, as described above, may need to be increased. It is normally set at 15 seconds.
If Nudging Operation is activated, the Electric Eye will be disabled when the Nudging
Timer has tripped AND the doors are fully open. If the nudging timer trips while the doors
are closing, the Nudging Buzzer will turn on, and the Electric Eye will remain active. If the
doors do reopen fully, then the Electric Eye will be cut out. The Safety Edge Input remains
active on nudging.
