Page 6: Overview
Overview The NB-4120-1 Double Belt, Bi-Parting Sliding Door Operator is designed and tested for lead shielding doors weighing up to 70,000 lbs (total both doors) operating at linear speeds of 6.0 in/sec maximum (each leaf in opposite directions) or a maximum horizontal operating force of up 1400 lbs (total both doors). - Page 7 AC power to the operator (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 8 A Rotary Position Transducer attached to the gear motor 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.
- Page 9 Supply Voltage: 230 VAC, +/- 10%, 60 Hertz, 3 phase 4 wires & GND (L1, L2, L3,.N & GND) are required to run the 3 phase motor and to provide 110VAC to the 24VDC power supply and PLC. The 3 phase AC Motor control and 110VAC power supply circuits are individually equipped with in-line circuit breakers for motor overload protection.
