MODEL 2082-141-47 Redundant Unit Controller

1.0 General

1.1 Equipment Description

The Model 2082-141-47 Redundant Unit Controller is used to power, monitor and control LNA or LNB

amplifiers configured in 1:1 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 (1.5A) is

provided for waveguide switch drive. The Model 2082-141-47 has +47 volts common and the 2082-141-47P

has ground common. LNA or LNB current is measured and a fault is signaled if the current deviates from user

selected thresholds. Multi-function switches select Auto, Local, or Remote operation, and the signal path in the

Manual mode. Remote operation via the RS232/RS485 M&C interface allows selection of the signal path.

Ethernet is available as option, -W8, -W18, or -W28. Contact closure to ground inputs allow selection of

Local/Remote, and Auto/Manual Modes. An LCD display shows each amplifier’s current, and signal path.

Form C relay contact closures indicate amplifier and power supply status, waveguide switch position, Auto,

Remote, and Manual operation. Connectors are DB37 for contact closure I/Os, MS3112E16-23S for the

amplifier plate signals, and DB9s for monitor and control and auxiliary external contact closure alarm inputs.

The 2082-141-47 is housed in a 1RU chassis and is powered by redundant power supplies fed by separate,

fused 100-240 ±10% VAC AC input connectors.

1.3 Control & Operation

The 2082-141-47 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. When the unit is in the local mode it will ignore any

serial commands it receives through serial M&C connector J3 or through the ethernet interface. Local mode

means control of the system is managed with front panel commands and external “ground to activate” inputs.

A grounded external input will override the front panel input that controls the same function. The following

table describes the “ground to activate” pins located on the DB37 parallel I/O connector and their function.

When the unit is in the remote mode it will respond only to serial M&C commands or ethernet Webpage and

SNMP commands.

Auto/Manual Select: Ground to activate Manual Mode.18

FunctionDB37 (J1) Pin

1.3.2 Auto/Manual (Switching) Mode

Auto mode is the default 'switching' mode of the controller. When in the auto mode the controller is

continuously monitoring the status of AMP1 and AMP2. If a fault is detected from AMP1 then AMP2 is

switched into the signal path of the faulted unit.

Manual mode may be set via a front panel command, an M&C port command, or by grounding the

AUTO/MAN external input (J1, pin 18). When the controller is in the manual mode it ignores fault and alarm

inputs and allows the user to manually operate the waveguide switch.

There are 3 methods available to manually operate the waveguide switch.

Method 1 is locally from the front panel interface. The unit must be in Manual Mode and Local Mode to use

this method.

Method 2 is remotely from the serial M&C or Ethernet (optional) interface. The unit must be in Manual Mode

and Remote Mode to use this method.

Method 3 allows the user to physically (“manually”) turn the waveguide switch by hand. The unit must be in

Manual Mode but may be in either Local or Remote Mode when using this method.

2082-141-47 Manual, Rev. 0 Page 5 01/15/14

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 2082-141-xx must first be properly wired to a

waveguide switch in order to perform any testing. The 2082-141-xx will not send any waveguide switch

control signals if the unit cannot read a valid position from the waveguide switch(s). The switch position read

from the waveguide switch is displayed on the bottom line of the main LCD display screen. If “ERROR!” is

displayed then the unit cannot read a valid position.

From the optional Webpage Interface there is a Switch Position status field. If “ERROR!” is displayed in that

field then the unit cannot read a valid position.

From the optional SNMP interface there is an Object ID named switchPos2082141. If the value 99 is read

from that object ID then the unit cannot read a valid position.

The 2082-141-xx reads the waveguide switch position through the MS connector J4 on the rear panel.

Typical waveguide switch wiring for Models 2082-141-47, 2082-141-47P are shown in the following 2

diagrams:

2082-141-47 Manual, Rev. 0 Page 6 01/15/14

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. These methods are referred to as LOCAL (which provides two (2) possible ways)

and REMOTE (one (1) way). These are described below.

2082-141-47 Manual, Rev. 0 Page 7 01/15/14

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 2082-141-47 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.

2) The LCD display will display the following message showing the current location of the switch:

Manually Set

POS=1>1 R

3) You may now select switch positions using the UP/DOWN switch. For a 2082-141-47, 1 for 1

controller, the switch position choices are: 1>1 (Primary active), or 2>1 (Backup active).

4) Once the Switch position is selected, push the PROGRAM/EXECUTE switch to go to the next menu.

5) Use the LEFT/RIGHT switch to move the cursor to R (return), then push the PROGRAM/EXECUTE

switch to jump to the SAVE SETTINGS menu.

1.4.3 Manual Override Knob.

To override auto switching via Manual Override Knob …

1) Place the unit in MANUAL MODE.

2) The LCD display will display the following message showing the current location of the switch:

Manually Set

POS=1>1 R

3) Once testing has been completed, the 2082-141-47 Redundant Unit Controller should be restored to

AUTO mode.

2082-141-47 Manual, Rev. 0 Page 8 01/15/14

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.)

3) When testing is completed, return the unit to AUTO mode through the following command…

{aaC9x}

where x = 0 sets switch to AUTO.

From the (optional) Ethernet Interface:

Webpage:

1. Select “Manual” control mode.

2. Select “Remote” control mode.

3. Select the desired set position, either 1 to 1 or 2 to 1.

4. Click “Update Other”.

SNMP:

1. Set ObjectID ctrlMode to 1 (MANUAL).

2. Set ObjectID ctrlSource to 1 (REMOTE).

3. Set ObjectID switchPos to the desired position, either 1 (AMP1 to 1) or 2 (AMP2 to 1).
