This chapter describes how to install and start-up the sat-nms ACU2-19V2. It is a step-by-step description without detailed description. If you need more detailed description for e.g. some parameter settings, please refer to chapter 5 Operation , all of the parameters are described here.

Before you start, please first read the Safety Instructions chapter. It contains some important recommendations to prevent damage from the ACU.

Then, we strongly recommend to do a first setup of the ACU on a lab desk before installing it at it’s final location. This is mainly for the following reason:

To setup the ACU’s IP parameters, the PC used for configuring and the ACU must either be connected to the same Ethernet hub or must be connected directly with a crossover cable. The initialization program does not work through routers or intelligent network switches.

Hence, the typical sequence of tasks when putting a sat-nms ACU2-19V2 into operation is as follows:

  1. Read the chapter 2 Safety Instructions .
  2. Set the ACU’s 4.3.1 IP address .
  3. 4.1 Mechanically mount the ACU2-19V2.
  4. 4.2 Connect the ACU to the antenna (position encoders, motor driver interface). Finally connect the mains power supply and the Ethernet network.
  5. Start up the system and set the parameters as described below.
  6. As last step enable the drive interface and start them up as described below.

If an existing 7200 ACU is replaced by a sat-nms ACU2-19V2, follow this procedure:

  1. Read the chapter 2 Safety Instructions .
  2. Stop step track at the 7200.
  3. Readout and write down azimuth, elevation and polarization values presented at the 7200 ACU
  4. Readout and write down azimuth, elevation and polarization soft limit values (high and low limit) presented at the 7200 ACU.
  5. Switch off the circuit breakers in the 7150-drive cabinet, so that the antenna cannot move.
  6. Disconnect the cables from the ACU 7200.
  7. Remove ACU 7200 from the 19� rack.
  8. Slide in the sat-nms ACU2-19V2.
  9. Set the ACU’s 4.3.1 IP address .
  10. 4.2 Connect the ACU to the antenna (position encoders, motor driver interface). Finally connect the mains power supply and the Ethernet network.
  11. Start up the system and set the parameters as described below.
  12. As last step enable the drive interface and start them up as described below.
