Overview
The
NB-4000 Commercial/Industrial Sliding Door Operator
has been designed, tested
(over 500,000 cycles) and manufactured by
brookfield industries, inc.
for linear
accelerator sliding doors weighing up to 30,000 lbs with a maximum travel of 60” and
horizontal operating forces up to 700 lbs and linear speeds not to exceed 4.5 in/sec.
If any
one of the following: horizontal operating force, weight, travel, speed or cycles exceeds the
rated value, please contact the Engineering Department for further evaluation.
The
NB-4000 is designed to be mounted directly to the top or front of the same horizontal
beam that supports a linear motion system. The NB-4000 can also be modified for wall
mounted applications, such as those used in bottom roller supported doors.
This power open/power close electro-mechanical operator with its state of the art
components, make it the strongest, most reliable and easiest to install in the industry today.
Refer to the
Terminal Strip Hookup
for all open, partial open, close, stop and
External
Safety Device
inputs, which are all Class (2) 24VDC normally open momentary contact
(except the stop input, terminal #10, which is a normally closed input).
Power supply
hookups for both Class (2) 24VDC, 110VAC and 230VAC(European installations) are also
indicated. The PLC then processes all this information, in addition to many other features
for proper control of these heavy lead doors. This door operator is patented under
US
Patent No. 6,177,771 B1
.
The
NB-4000 Commercial/Industrial Sliding Door
is compliant with
UL 325 Section 30.2
External Entrapment Protection
(Fail Safe/Self-Monitoring)
providing all External Safety
Devises are wired and installed per this manual.
We are Authorized to Mark the
NB-4000
with the
ETL (US and Canada),
and
CE
markings
from Intertek Testing Services to assure compliance with UL 325(Control No. 3011624),
FCC Part 15 (Emissions) and the following International Standards: EN 60335-1 and -2
(Safety), EN 61000-6-2 (Immunity), EN 61000-6-4 (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 (8) LED 24 VDC inputs and (6) LED outputs with (3) isolated
commons.
