- Page 6 Overview The NB-4120-2-DC, Single and Bi-Parting Sliding Door Operator, is designed and tested for lead shielding doors weighing up to 35,000 lbs (single door)/17,500 lbs (each bi-parting door), operating at linear speeds of 6.0 in/sec maximum (single door)/12.0 in/sec maximum (bi-parting doors), or a maximum horizontal operating force of 700 lbs (single door) or 350 lbs (each bi- parting door).
- Page 7 stations and outputs to motor controls. This extremely compact unit houses (8) LED 24 VDC inputs and (6) LED outputs with (3) isolated commons. 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 presence sensors.

(Terminal L1, L2, L3 and Terminal N). The NB-4120 features the same Absolute Position Feedback Control system and software as other brookfield industries, inc. door operators. There are no limit or proximity switches to adjust or install for any of the door positions under normal operation. - Page 9 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.

Page 10: Manual Operation
Manual Operation: In case of loss of power, manual operation shall be less than 50 lbs to open per UL 325 Interruption of Power. This is accomplished by engaging a flexible shaft into the rear shaft of the motor via a remote control cable. A lever arm, which activates the remote control cable, and a 7”... - Page 11 power to stop the door in the open position. Pushing in the mushroom head switch will reset the operator. Sequence of events: pulling out the mushroom head E-stop* (see photo), removes power to normally closed (N.C.) Relay 1** (providing DC power to the motor) and normally open (N.O.) Relay 2** (disconnecting AC power to the motor control) and provides for Emergency Open Operation or performs a Battery Backup Test.

Page 13: Installation Instructions
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. Premature failure may occur if any part of the installation is not done properly. To install the NB-4120-2-DC on bi-parting doors, refer to drawings NB-4120-2DC4 or NB- 4120-2DC-Travel. - Page 14 2. Mount take-up end – refer to drawing NB-4120-2C4 Verify take-up end is level Using the reference center line from the door attachments (from step 1) assure the pulley is the same distance from the track center line within (+/-) 1/16”. (shim as required) Minor adjustments can be made by loosening the shaft collars, loosening the set screws on take up bearings, and moving the take up shaft from side to side...
