- Page 2 This document describes a family of products that allow an RC2000 antenna controller to interface with antennas powered by either 90 or 180 volt DC motors (RC2K90INT-1 and RC2K90INT-2) or other motor types (RC2KINT). The RC2000 antenna controller is designed to interface directly with antennas which employ 36-Volt DC motors (8 amps maximum) and single phase pulse type position sensors.

Page 3: Theory Of Operation
RC2000 Antenna Controller Interface Box Dual-Speed Antenna Azimuth and Elevation Movement The RC2000 antenna controllers use a pulse width modulation scheme to obtain slow speed movement when interfaced to 36 volt DC motors. This pulse width modulation scheme is not compatible with the interface box. - Page 4 RC2000 Antenna Controller Interface Box...
- Page 5 RC2000 Antenna Controller Interface Box Note that the scheme shown in Figure 1 does not support slow speed movement. RC2000 antenna controllers normally vary motor speed by rapidly switching the 36 volt antenna drive signals off and on - which gives an average voltage of less than 36 volts. If this pulse width modulated signal is applied to the circuit of Figure 1, the relays would chatter and produce erratic operation.

Page 6: Circuit Description
The RC2K90INT-1 interface box uses a single KBPB motor drive module. The motor drive module accepts AC line voltage and contact closures produced by the 2K90INT-2 circuit board and generates the drive voltage used to power the motors. - Page 7 KBPB-225 is used with 90 volt DC motors a modification is performed to the motor drive to limit the voltage applied to the motors to 90 volts DC. This modification is described in section 4.4. The Operating instructions for the motor drive module(s) are included with the operating manual for the RC2K90INT-1 and RC2K90INT-2 interface boxes.

- Page 9 The circuit associated with latching relay K4 is used by the RC2K90INT-1 interface box. With the RC2K90INT-1 interface box a single KBPB DC motor drive module is present and the latching relay is used to route the motor drive current to either the azimuth or elevation axis. The relay will not be included with the RC2K90INT-2 and RC2KINT model interface boxes.

Page 13: Heater Option
RC2000 Antenna Controller Interface Box 4.0 Heater Option A heater option has been developed for the RC2K90INT series of interface boxes. The KB Electronics KBPB Drive used in RCI 90VDC interface boxes has a low temperature rating of 0 C. This is inadequate for most environments. - Page 14 RC2000 Antenna Controller Interface Box requires a pair of conductors. Since the RC2000 motor drive outputs are not actually carrying motor drive current light gauge conductors (16-20 AWG) can be used, shielded cables are not required. In most cases the cable used to connect the RC2000 to the interface box will also include the conductors required to interface the RC2000 to the azimuth and elevation position sensors.
- Page 16 CONFIG mode item can result in damage to the interface box. Simultaneous 0 - DISABLE With the RC2K90INT-1, simultaneous azimuth and Az/El Enable elevation movement is not allowed. With the RC2K90INT- 2, the user will generally want to enable simultaneous...
- Page 17 For interface boxes configured for dual speed azimuth and elevation movement, the slow speed adjustment pots are located on the 2K90INT-2 circuit board. For the RC2K90INT-1 interface box adjust the KBPB1_SLO pot to vary the slow speed for both the azimuth and elevation axis. Adjust the KBPB1_FST pot to set the fast speed for both axis.

Earlier model KBPB units employ thru-hole printed circuit board technology. Appendices and Attachments This section includes the following attachments ... • KBPB Manual (for model RC2K90INT-1 and RC2K90INT-2 interface boxes) • A data sheet on the Omron type G2R relay. •... - Page 19 Notes 2 are used for the RC2K90INT-1, 4 are used for the RC2K90INT-2 Only one motor drive module is used for the RC2K90INT-1, two motor drives are used for the RC2K90INT-2. When a KBPB-225 motor drive module is used with a 90 volt DC motor the KBPB should be modified as described in Section 4.4.4.

Page 21: Making The Connections
• When splicing the sensor cables please refer to figure 7 in the RC2K90INT-1 manual. Belden 1083A cable has been successfully used to interconnect the RC2000C to the RC2K90INT-1 interface box. This cable consists of 4 individually shielded triples (or triads). The conductor size is 20 AWG and the shields are equipped with a drain wire. - Page 22 Belden 8772 cable in the interface box. Please reread section 3 of this manual and refer to figure 7 in the RC2K90INT-1 interface box manual before making the splice. Use the 3M Scotchlok connectors to make the splice. Proper connection of the sensors is critical to the operation of the antenna controller.
- Page 23 Prodelin 3.8m Antenna Installation Kit does not come in contact with the sensor housing. Use the 3M Scotchlok connectors to make the connections. 5. At the azimuth and elevation motor terminal boxes, connect the 16/3 cables to the motor lead wires (refer to figure P1).
