Overview
The brookfield NB-500 Main/Sub Swinging Door Operator has been designed,
tested and is manufactured by brookfield industries, inc. in accordance with UL
325 and ANSI 156.10 for linear accelerator swing doors weighing up to 4,500 lbs
and 66” wide. The NB-500 can be expected to safely operate doors at the
maximum weight and width for at least 500,000 cycles, providing the door is set
within the ANSI 156.10 speed criteria and the rated operating torque of 1000 lb-in
(reflected to the operator) has not been exceeded. If any one of the following:
torque, weight, width or cycles exceeds the rated value, please contact the
Engineering Department for further evaluation.
The Main/Sub operator is intended for use on double doors with an astragal and
is designed to open the Lead Door first and close last, while the Follow Door
opens last and closes first. The Lead Door and Follow Door can be setup as
either the left hand or right hand operator. The Main Operator is designated as
the right hand operator, while the Sub is always the left hand. The Main
Operator houses a common CPU (Central Processing Unit), Analog/Digital
Converter and Class (2) 24 VDC Power Supply as well as a common Terminal
Strip for hookup of input commands. All other components such as the Motor
Control, Drive Train and Rotary Position Transducer are independent to each
operator.
The CPU has been uniquely programmed to assure the doors remain in
sequence during the closing cycle if one or both doors are in the Entrapment
mode. The CPU program has been modified to automatically close the doors.
The time the doors stay open can range from 0-300 seconds. This setting is
titled Closing Time on the Data Access Unit (DAU). If you do not want the
automatic closing time feature, simply type in the value 301 or higher and the
automatic closing time will be disabled.
This power open/power close electro-mechanical operator with its state of the art
components and mostly all aluminum construction, make it the lightest and
strongest in the industry today. Refer to the Wiring Legend for Terminal Strip
Hookup for all open, close, stop and safety device inputs, which are all Class (2)
24VDC momentary contact (except terminal 9 which must be a maintained
contact). Power supply hookups for both Class (2) 24VDC and 110VAC are also
indicated. The PLC then processes all this information, in addition to many other
features for proper control of these heavy lead doors, which are patented under
US Patent No. 6,177,771 B1.
We are Authorized to Mark the NB-500 with the ETL (US and Canada) Listing
from Intertek Testing Services to assure compliance with UL 325(Control No.
3011624), FCC Part 15 (Emissions) CAN/CSA-C22.2 and ICES-003. The
“listing” reports specifically refer to the heavy commercial/industrial doors
associated with linear accelerator rooms.
Logic Control:
This Operator offers the latest technology in PLC (Programmable Logic Control).
The following (3) modules snap to a DIN rail base:
CPU (Central Processing Unit)- processes and stores data in its internal
register such as door position presets, inputs from pushbutton stations and
outputs to motor controls. This extremely compact unit houses the required (8)
LED 24 VDC inputs and (8) LED outputs.
Analog/Digital Converter- converts the analog signal of the Rotary Position
Transducer to a digital value.
Class (2) 24 VDC Power Supply- converts 110-supply voltage to Class (2)
24VDC power to operate the CPU, A/D converter, Rotary Position Transducer
and any presence sensors.
These plug-in modules with LED make diagnostics and replacement of parts
easy and quick to perform.
Interface with the PLC is necessary to adjust Door Position Presets in the field.
This is accomplished by plugging in an 8- Pin Phoenix connector to the back of
the Data Access Unit (DAU) and a round female connector into the side panel
of the operator. The DAU is a hand held, touch screen device that is purchased
separately.
The CPU has been programmed to adjust on the fly, such door position presets
as Back Check, Full Open, Latch Check and Full Closed. The CPU also
provides a door reversal function (a term we call Automatic egress) when UL 325
section 29.4 Entrapment criteria has been violated. The NB-500 has also been
programmed to automatically clamp the door against the frame after each cycle.
The motor will shut off after being in contact with the frame for about 5 seconds.
This feature will maximize repeatability of the door-closed position, which
minimizes the chance of the frame interlocks from being disengaged. . If an
external force acts on the door, such as a small pressure differential or if the door
is simply pushed open above the Auto Close Enable preset value, the motor will
restart and “clamp” the door against the frame once again.
Input commands to activate the door operator for normal operation is
accomplished by making the appropriate connections on the Terminal Strip
Hookup. By connecting one side of a momentary contact SPST switch to
Terminals 14 (Open), 12 (Close) or 10 (Stop) and connecting the other side of
the switch to Terminal 1, provides the customer with discrete control by using a
separate switch for each input command. Reversing the direction of the door
while it’s moving (dynamic) can be accomplished with any input that changes
direction. Upon request, we can program the CPU and the Data Access Unit
(DAU) to automatically close the door after an open command. The time the
door stays open can be preset on the DAU from (0-300 seconds) and is titled
Closing Time.
Inputs for External Safety Devices that can be door mounted, such as
reversing edge pressure switches or presence sensors (such as the BEA
SuperScan) are provided on the Terminal Strip Hookup Legend. To reverse
the door in the closing cycle, hookup normally open switch of sensor to
Terminal 11 and 1. To reverse the door in the opening cycle, hook up to
Terminal 20 and 1. Terminals 11 and 20 are inactive when the door is not
moving. External safety devices can also be set up to Stop the door by
connecting to Terminal 10 and 1. Assure the safety devices are attached to the
door in such a manner that will provide the best safety performance, as well as
allowing sufficient clearances under normal operation to prevent inadvertent
activation. Refer to the external safety device owner’s manual for proper
installation and use. Presence sensors that are frame mounted, such as the
BEA Bodyguard (DK-12), can be used to disable any door movement when the
door is in the open or closed position, through a maintained connection between
Terminal 9 and 1. This feature will not prevent the door from being activated
when in any position other than the fully opened or the full closed. The lockout
device need not be purchased because the PLC has been internally
programmed. Any presence sensor that runs on 24 VDC, can be powered up by
connecting to Terminal 3 and 1 of the Terminal Strip Hookup Legend.
The Stop command (terminal 10) will stop the door in any position when
activated but it will not prevent a motor drive from malfunctioning nor is it a true
emergency stop.
Emergency Stop (E-Stop) can only be accomplished by disconnecting AC
power to the operator (Terminal L1 and Terminal N).
A Rotary Position Transducer attached to the worm gear output shaft provides
the position of the door. As the door changes position, the output signal from the
transducer varies in value. This signal, once converted to a digital value, is
stored in the CPU for further processing. This devise does not need to be
“homed” or reset if there is a power loss or electrical noise nor does it need to go
through “learn speed” after power up or after adjustments have been made. This
is what is called Absolute position feedback control.
Motor Control:
The NB-500 uses a state of the art Regenerative (4-Quadrant) 90 VDC Motor
Control. This provides the best assurance that the door’s high inertia
characteristics will not “overhaul” (or “freewheel”) the motor; thus, resulting in
controlled door motion. The NB-500 now features a multi-speed board that
attaches to the top of the motor control. The logic panel is greatly simplified
with the elimination of the external speed pots and the associated wiring. The
new multi-speed board features control of (4) independent speeds. The NB-500
now has the flexibility of controlling separate latch check(creep close) speeds
(Preset 1) and back check(creep open) speeds (Preset 2) as well as close
speeds (Preset 3) and open speeds (Preset 4). The motor control also features
additional trimpots, which greatly improve the performance of the drive and
motion profile of such heavy doors. The DB (Dead Band) trimpot sets the
amount of main speed trimpot rotation to initial output voltage and controls the
amount of delay before regeneration starts. If not properly set, the motor may
oscillate or continue to hum. The RESP (Response) trimpot adjusts the dynamic
response of the system; therefore, increasing this setting will increase response
time( if set too high , unstable operation may result). The IR Comp trimpot
determines the amount in which the motor speed is held constant as the motor
load changes. For example, if set too low, the motor may not obtain the desired
speed fast enough or not at all. If set too high, the motor may oscillate. The
RCL (Reverse Current Limit) trimpot and FCL (Forward Current Limit) trimpot
adjusts the armature current limit or motor torque in their respective directions.
When properly set, the operator will have sufficient torque to operate in both
directions, while at the same time limiting the current to the motor in order to stall
and reverse the door’s direction so that Entrapment Protection requirements
will be met (this eliminates the need for unreliable and hard to adjust devises
such as a manual or electromagnetic clutch). The MAX (maximum speed)
trimpot adjusts the voltage or speed of the motor in the forward and reverse
directions. The FACC (Forward Acceleration) trimpot adjusts the acceleration
time in the forward direction as a function of the maximum rated motor speed. It
also controls the Reverse Deceleration time. The RACC (Reverse Acceleration)
trimpot adjusts the acceleration time in the reverse direction as a function of the
maximum rated motor speed. It also controls the Forward Deceleration time.
Overload Protection for the DC motor is provided by using the appropriate line
fuse to the 110VAC power supply of the motor control (see wiring diagram) and
by the proper setting of the FCL and RCL trimpots, which controls the amount of
DC current to the motor in both directions.
Drive Train:
A 5:1 Right Angle Worm Gear Reducer (with a center distance of 2.06”)
provides the high output torque necessary to operate these heavy doors. A
heavy-duty flexible coupling joins the worm gear to the 102:1 In-Line Helical
Gear Reducer; thus, substantially reducing torque before being coupled to a 1/8
HP 90VDC Permanent Magnet Motor, 1750 RPM TENF.
Battery Backup (option):
When power is interrupted, and if the door is in any position other than fully open,
the battery backup will be activated and provide low voltage DC power directly to
the motor. The system is designed to open the door once for each power
interruption at a constant speed. This system is not designed to open and close
the door repeatedly. A float charger is included to provide a constant charge on
the battery. These components are installed in a NEMA 1 box with a test switch
that will interrupt power and allow for testing the system. Also included is an end
of travel limit switch, which must be installed so that it disconnects power to the
motor when the door is fully open. (this limit switch is only for use in battery
backup mode and not for normal operation).
Assure used batteries are disposed of at the appropriate drop off centers.
This is a redundant system and does not replace or substitute any requirements
of UL 325 section 29.3 Interruption of Power for manual operation.
Manual Operation:
In case of loss of power, manual operation shall not be more than 50 lbs to open,
when applied at the widest point on the door with the power removed (ref. UL325
29.3).
Supply Voltage:
115 VAC, +/- 10%, 50/60 Hertz,single phase. Motor control and power supply
are equipped with in-line circuit breakers. Surge protection and filtering of the
supply voltage is featured to protect door operator components and to assure
reliable performance (immunity) as well as minimizing RF noise (emissions).
For installations requiring 230 VAC, 50/60 Hz single phase service, we now offer
a conversion kit (optional).
brookfield NB-500 (Main-Sub) Installation Instructions
Although each Door Operator has been fully inspected and tested prior to shipment, assure that no
physical damage has occurred during shipping and handling.
1. Position Door Operator and the applicable door attachment in the horizontal and vertical positions
as indicated on installation drawing NB-500-MS-4 and NB-500-MS-5 for pull open applications and
drawings NB-500-MS-2 and NB-500-MS-3 for push open applications.
2. Mount Door Operator base plate with (6) 3/8”diameter Grade 5 bolts and tighten properly (not
included). For pull open application, weld Mounting Block directly to door as indicated or bolt
Slider Block directly to door with (2) 3/8”diameter socket head cap screws (included). For push
open applications, mount the door attachment pivot with (2) 3/8” diameter grade 5 bolts and
properly tighten with lock washers.
3. With Linkage Arm disconnected, measure force near the lock edge of the door to accelerate the
door to opening and closing speeds. This force, times the distance to the hinge pin centerline shall
not exceed the Rated Operating Torque of 1000 lb-in.
4. Check Linkage Arm to assure it doesn’t interfere with the door or Slider Block. In addition, make
sure cam follower (of Linkage Arm) is properly engaged in Slider Block. Proper engagement is
defined as full engagement (–1/16”) max.
5. With Linkage Arm connected and power removed, measure force to open door/ backdrive (at
constant velocity). This force must be ≤50 lb (per UL 325 section 29.3) and be applied near the
lock edge of the door.
6. All PLC and Motor Control settings have been preset by brookfield industries, inc.; however, we
recommend these values be double-checked with the Parameter sheet supplied.
7. Install activation switches or push button stations: (a) within sight of the door, (b) at a minimum
height of 5’ so small children cannot reach and (c) away from moving parts of the door.
8. Before wiring 115 AC supply voltage to operator, assure power is disconnected and all “Lock-Out”
Safety Procedures have been strictly adhered to.
9. Connect 115 VAC and class (2) 24 VDC wiring as shown on Terminal Strip Hookup Legend and
Wiring Diagrams. Disconnect “Lock-Outs” and turn on breakers.
10. Assure speed trimpots on Multi-Speed Board (Presets 1-4) are in the 25% range before activating
operator.
11. Make sure that all Safety Instructions and Warnings have been followed.
12. Activate Open, Partial Open and Close commands.
13. Adjust Presets 1-4 clockwise until the minimum opening and closing times listed in Table 1 have
been obtained.
14. Adjust Door Position factory presets as required using the DAU. Refer to the DAU Instruction,
Door Position Setup Instructions and Parameters as required.
15. Check and adjust, if necessary, the trimpot settings (refer to the Parameter sheet) on the Motor
Control.
16. Check Entrapment Protection in both directions. This is accomplished by measuring the force
that prevents a stopped door from moving in a particular direction and can be accomplished with a
simple force gage. This force must be ≤40 lbs and is applied at the latch side per UL 325 section
29.4 Entrapment. When measuring this force be careful not to erroneously measure the inertia
force of the door. This can be accomplished by first stopping the door without the gage, then
substituting the gage with the minimum force to keep the door from moving in that particular
direction. This force is adjusted by varying the FCL and RCL trimpots settings on the Motor
Control.

Door Position Setup Instructions
1. The factory settings are a starting point and may need to be adjusted for each application
depending on installation and environment variables.
2. Initiate a signal to have the operator close the door (Close button or Push Open/Close).
When operator goes into Latch Check, it will move slowly until it rests fully against the
frame. It will run for approximately 5 sec., then shut off. Insure that the Latch Check speed
pot is set so that the door doesn’t “slam” into the frame. The Auto Close Enable can now be
set per the following.
a. After the door moves against the frame, runs for 5 sec., and shuts off; view the Door
Position (preset 300) value. Cycle door several times to assure repeatability.
b. Set the Auto Close Enable preset to the Door Position value plus 30 units (i.e. if the Door
Position is 310, set the Auto Close Enable to 340). Note: Some installations may
require slightly higher/lower values for best results.
3. Check position of door when fully open. Assure that the door opens fully without the cam
follower bottoming out in the cam follower slot. Adjust Back Check and Full Open if
necessary.
4. Adjust the Partial Inhibit value to the desired position to allow required access through
doorway.
•Delays the scanning of the door position in the PLC until after the door starts moving to compensate for any play or
backlash of the door operating system. This also allows for the time it takes of the door to stop and reverse while
door is in operation. The default value of 4 seconds (40 tenths) covers speeds for doors weighing #6000-#12000.
For doors weighing substantially < #6000 or whose cycle time is very high, this value may and
should decrease.
