MODEL 2082-14x-47 Redundant Unit Controller 1.0 General 1.1 Equipment Description The Model 2082-14x-47 Redundant Unit Controller is used to power, monitor and control LNA or LNB amplifiers configured in 1:1 (2082-141-47) or 1:2 (2082-142-47) redundancy. Front panel LEDs indicate power, status (online, standby, alarm), and mode (auto, manual, local, remote). Up to 600 ma is available to power each amplifier and +47 VDC is provided for 1:1 (1.5A) or 1:2 (3A) waveguide switch drive.

Total Switch over time 100 ms max., based on switch specifications Drive Voltage 47 Volts, 1.5A (for -141-47), 3A (for -142-47) Alarm and Control, M&C Alarm Output Signal Form C relay: 100 VDC, 0.5A, 3W max.
1.3 Control & Operation The 2082-14x-47 Redundant Unit Controller is designed to be 'controlled' either Locally or Remotely (Local/Remote) and the 'switching' is either Automatic or Manual (Auto/Manual). The controller defaults to Local (control)/Auto (switching) mode. These are described in more detail below. 1.3.1 Local/Remote (Control) Mode Local mode is the default 'control' mode of the controller.
1.4 Setup/Testing At the time of installation / testing the user needs to verify that the controller is properly installed and that the 'back-up' signal path and LNA are functioning properly. The 2082-14x-xx must first be properly wired to a waveguide switch in order to perform any testing. The 2082-14x-xx will not send any waveguide switch control signals if the unit cannot read a valid position from the waveguide switch(s).
The micro controller in the 2082-141-xx determines the switch position by detecting the presence of switch common voltage on either Pos1 or Pos2. If no presence of switch common voltage is detected then the position is reported as “ERROR!”. The 2082-141-xx will not send waveguide switch control signals if it cannot determine a valid switch position. There are three possible methods for a user to override auto switching while in Manual mode to perform waveguide switch testing.

2082-14x-47 Manual, Rev.
1.4.1 LOCAL. As mentioned above, local provides two possibilities to override auto switching. The first is via the Front Panel Menu and the second is via the Manual Override Knob located on the waveguide switch (if so equipped.) Both of these require that the 2082-14x-47 be placed in the MANUAL MODE. 1.4.2 Front Panel Menu. To override auto switching via the Front Panel Menu … 1) Place the unit in MANUAL MODE.
1.4.4 REMOTE To override auto switching remotely… [The unit must be in the REMOTE mode to execute any remote commands.] From the serial M&C Interface: 1) SET the unit to MANUAL mode through the following command… {aaC9x} where x = 1 sets switch to MANUAL. 2) To manually test the switches, send the following remote M&C command to the unit. {aaCAx} where x = 1 sets switch to position 1 (Primary active), and x = 2 sets switch to position 2 (Backup active.
1.5 M&C Interface 1.5.1 Remote Serial Interface Protocol: RS232C, 9600 baud rate, no parity, 8 data bits, 1 start bit, and 1 stop bit.

1.6 Environmental Use Information A. Rack-Mounting - To mount this equipment in a rack, please refer to the installation instructions located in the user manual furnished by the manufacturer of your equipment rack. B. Mechanical loading - Mounting of equipment in a rack should be such that a hazardous condition does not exist due to uneven weight distribution. C.
2.0 Installation 2.1 Mechanical The 2082-14x-47 consists of one PCB housed in a 1 RU (1 3/4 inch high) by 16 inch deep chassis. Two redundant switching +27 VDC power supplies are diode “OR’ed to provide +26 VDC for the assembly. The 2082-14x-47 can be secured to a rack using the 4 holes on the front panel. Figure 2.0 shows how the 2082-14x-47 is assembled. POWER SUPPLY 1 J4 from MS conn. J7 from PS2 J6 from PS1 POWER SUPPLY 2 PCB FIGURE 2.0 2082-14x-47 Manual, Rev.
2.2 Rear Panel Input/Output Signals Figure 2.1 shows the input and output connectors on the rear panel.

2.3 Front Panel Controls and Indicators Figure 2.2 shows the front panel controls and indicators. DS5 - AMP2 STATUS LEDs Indicate whether AMP2 is in Standby mode, Online, or in an Alarm state. LCD DISPLAY Displays measured current in each unit/amp, and the current paths. S1 - MENU/EXECUTE BUTTON Press this to get into Program mode and to execute any changes.
2.4 Installation / Operation 2.4.1 Installing and Operating the 2082-14x-47 1. Connect external Amplifier Plate Assembly to 2082 via MS connector, J4.(Figure 2.1). 2. Connect two 100-240 ±10% VAC, 47 - 63 Hz power cords to AC1 and AC2 on the back panel (Figure 2.1). 3. Be sure DS8 & DS9 (green, DC Power) are on and red Alarm indicators are off (Figure 2.2). 4. Check that DS1 and DS2 are lit. If not, then either a fuse is missing or blown in F1 or F2, respectively (Figure 2.1). 5.
2.5 Menu Settings 2.5.1 Functions This section describes operation of the front panel controls. There are three operator switches, the LCD display and alarm indicator LEDs. All functions for the equipment are controlled by these components. The functions are (see Figure 2.4): Power Up Normal Display Menu 1 Select AUTO/MANUAL mode NOTE: If MANUAL mode, then --> Menu 1a Manually set switch positions.
2.5.2 Control Switches 1. Menu/Execute - Any change to the programming of the unit must be initiated by pressing the Menu/Execute switch and completed by pressing the Menu/Execute switch. 2. Horizontal Switch - This switch is mounted so its movement is horizontal and moves the cursor left or right. 3. Vertical Switch - This switch is mounted so its movement is vertical, and changes settings in each menu. 2.5.
Menu 1.a Manually set POS= 1>1 R Toggle between switch positions with the UP/DOWN switch. Push the PROGRAM/EXECUTE switch to go to the next menu. Use the LEFT/RIGHT switch to move the cursor to R, then push the PROGRAM/EXECUTE switch to jump to the SAVE SETTING menu. Menu 2 LOCAL/REMOTE= LOCAL R Toggle between LOCAL and REMOTE mode with the UP/DOWN switch. Push the PROGRAM/EXECUTE switch to go to the next menu.
Menu 3b.1 Manually set AMP1 NOM=.XXX A R This menu is entered only if “N” is selected from menu 7a. This allows the user to manually enter a nominal value for AMP1 current. Push the PROGRAM/EXECUTE switch to go to the next menu. Menu 3c AMP1 WINDOW=10% R Use the up and down switches to set the allowable operating range of AMP1 current. This percentage is the amount of positive or negative deviation from the nominal value before AMP1 alarm is tripped.
Menu 4b.1 Manually set AMP2 NOM=.XXX A R This menu is entered only if “N” is selected from menu 8a. This allows the user to manually enter a nominal value for AMP2 current. Push the PROGRAM/EXECUTE switch to go to the next menu. Menu 4c AMP2 WINDOW=10% R Use the up and down switches to set the allowable operating range of AMP2 current. This percentage is the amount of positive or negative deviation from the nominal value before AMP2 alarm is tripped.
