1 Introduction
T h e sat-nms Antenna Control Unit is an antenna controller / positioner with optional satellite tracking
support. It may be operated as a standalone unit or in conjunction of the sat-nms ACU-IDU, a PC based
indoor unit which offers extended tracking capabilities and a full featured visualization interface.
The sat-nms-ACU is available as:
sat-nms ACU-ODM: only the core-module integrated in a compact case prepared for mounting on a
35mm DIN rail
sat-nms-ACU-ODU: complete antenna controller system for AC- or DC-Motors integrated in an
outdoor cabinet that could be mounted directly to the antenna. By mounting a sat-nms LBRX beacon
receiver into this cabinet, you have a complete antenna tracking system in a compact cabinet directly
at your antenna.
sat-nms-ACU-RMU: complete antenna controller system for AC-Motors integrated in a 6RU 19inch
rack mount case for indoor use
sat-nms-ACU19: complete antenna controller system for DC-Motors integrated in a 1RU 19inch rack
mount case for indoor use
For detailed description please refer to the sat-nms documentation CD or www.satnms.com/doc
Main benefits of the sat-nms ACU are:
The ACU outdoor unit is able to act as a standalone antenna control and tracking system without an
indoor unit required.
The ACU provides an Ethernet interface using the TCP/IP and HTTP Internet protocols. It can be
controlled using any PC providing an Ethernet interface and a web browser like the Microsoft Internet
Explorer. The ACU runs a web server which acts as a user interface to the antenna controller.
The ACU is prepared to read the receive level of a sat-nms beacon receiver through the TCP/IP
interface.
The flexible interface design of the ACU enables it to control most types of motor driving antennas for
geostationary satellites.
Supported motor controllers are (configurable in the field):
Power relays: This simple solution is suitable for antennas using 2-speed AC motors.
Frequency inverters: Speed and acceleration ramps are programmed into the inverter module with this
solution.
Servo controllers: Used for DC motors at small antennas.
Supported position sensors are (separate hardware interface modules for each axis:
Resolver Interface: The resolver interface module contains a resolver to digital chip which does the
decoding of the resolver sin/cos signals.
SSI Interface: SSI is a high speed serial interface used by modern digital position encoders.
DC Voltage Interface: The third position encoder interface module contains an A/D converter which
is suited to measure the DC voltages produced by simple inductive angle encoders. This application is
for small antennas especially in the SNG business.
The paragraphs below give a short overview to the contents of the documentation. A subset of this
documentation is stored on the device itself, the complete documentation is available on the sat-nms
documentation CD and at www.satnms.com.
Safety Instructions: This chapter gives an overview about the safety precautions that have to be
(C) 2017, SatService GmbH www.satnms.com ACU-RMU-UM-1707 Page 4/80

observed during installation, operation and maintenance.
Unit Overview: The installation chapter gives informations about the different modules that are
integrated in the ACU (not ACU-ODM and ACU19).
Installation/Start-up: The installation chapter guides through the installation and setup of the ACU
outdoor module. It describes the mechanical concept of the ACU and the assignment of the ACU's
connectors. It gives you informations about the starting up procedure. Finally you learn in this chapter
how to set the ACU's IP address, which is a essential precondition to operate the ACU by means of a
web browser.
Operation: The sat-nms ACU is operated using a standard web browser like the Internet-Explorer on
MS Windows based computers. The user interface design is straight forward and clearly structured.
Operating the ACU is mostly self-explanatory. Nevertheless, the 'Operation' chapter outlines the map of
web pages which make up the ACU user interface and elaborately describe the meaning of each
alterable parameter.
Frontpanel Operation : The sat-nms ACU19 and the sat-nms ACU-RMU optionally are equipped with
a frontpanel Human-Machine-Interface. This chapter describes how to use this interface.
Remote Control: The ACU outdoor module provides a versatile remote control interface. A monitoring
& control software may fully operate the ACU either through a TCP/IP network connection or through
the RS232 interface of the ACU. This chapter describes the communication protocol used for remote
control and lists all parameters accessible through the remote interface.
Theory of Operation: This chapter gives a short overview how the ACU works. It also describes the
different tracking algorithms and their parameters. The interaction with a beacon receiver is described
as well. Knowing about the theory regarding this functions helps to find the best parameter settings for
a given application.
Specifications: At the end of the document, the specifications applicable to the sat-nms ACU are
summarized in this chapter.

2 Safety Instructions
Safety
The mains shall only be connected provided with a protective earth wire. Any interruption of the protective
wire, inside or outside the sat-nms ACU, is likely to make the unit dangerous. Intentional interruption is
prohibited.
The unit described in this manual is designed to be used by properly-trained personnel only.
Adjustment, maintenance and repair of the exposed equipment shall be carried out only by qualified
personnel who are aware of hazards involved.
Refer servicing to qualified personnel.
To prevent electrical shock, do not remove covers.
For the correct and safe use of the instrument, it is essential that both operating and servicing personnel
follow generally accepted safety procedures in addition to the safety precautions specified in this manual.
Whenever it is likely that safety protection is impaired, the unit must be made in-operative and secured
against unintended operation. The appropriate servicing authority must be informed. For example, safety is
likely to be impaired if the unit fails to perform the intended measurements or shows visible damage.
Ensure that the cabinet is proper connected to the protective earth conductor.
The circuit breaker, that fuses the mains for the sat-nms ACU has to switch off all phases AND the neutral
wire as well.
WARNINGS
The outside of the equipment may be cleaned using a lightly dampened cloth. Do not use any cleaning
liquids containing alcohol, methylated spirit or ammonia etc.
Follow standard Electrostatic Discharge (ESD) procedures when handling the Unit.
Apply the appropriate voltage according to the attached schematic.
In case of switching off all the circuit breakers is still voltage available at the mains terminals!
Only use shielded cable to connect the AZ- and EL-Motor. The other components in the cabinet might
be jammed through the harmonic waves the frequency inverters inject into the motor wires.
Use only double shielded twisted pair cables (e.g. CAT7 Ethernet cable) to connect the resolvers to the
sat-nms ACU
Only ACU-ODU: If the Unit is equipped with an optional air ventilation, avoid direct contact with jets
of water, normal rain is no problem.

3.1 Frontpanel Keyboard
The keyboard is an optional interface for local operation without using e.g. an external computer. It is
always delivered together with the Frontpanel display. Besides the keyboard you find 3 LEDs that show the
actual state of the ACU-RMU (fault state / limit switch state / motor movement) Please refer to chapter
Frontpanel Operation for detailed informations.
3.2 Frontpanel Display
The Display is an option for local operation without using e.g. an external computer. It shows all of the
desired parameters. It is always delivered together with the frontpanel keyboard. Please refer to chapter
Frontpanel Operation for detailed informations.
3.3 Frequency Inverters, Motor Controller
For bigger antennas most of the time three phase motors are used. These are connected to frequency
inverters which are the high power interface between the sat-nms ACU-ODM module and the motors.
Please take into account that some of the frequency inverter parameters are motor dependent and
that these have to be changed to your specific antenna motors.
The following chapters give a short overview of the frequency-inverters operation. If you need more
detailed informations, please refer to the manual of the frequency inverters.
3.3.1 Display and function of the buttons
The frequency inverters used in the sat-nms ACU-RMU are equipped with a Basic Operation Panel (BOP)
that shows you all of the parameters set to the frequency inverter. It also is able to show you the actual
values of frequency, voltage and output voltage. The following picture shows how the BOP looks like:
