brookfield NB-2000HD2 Door Operator 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
in the horizontal and vertical directions as indicated on installation drawing
NB-2000-HD2-81
for pull open applications.
Locate
Slider Block
assembly on door as shown on installation drawing
NB-2000-HD2-81
for pull
open applications. For Push Open applications refer to drawings:
NB-2000-HD2-86, -87
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 application, 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 6000 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.
