EXHIBIT INSTALLATION AND SETUP 5 1. INSTALLATION AND SETUP 1.1. PACKAGE When the amplifier is delivered to you it is packed in a cardboard box with styropor inlays. Please handle the package with care. In case of damage you may need it for the ALPIN 200 to be transported back safely. 1.2. CONNECTIONS POWER CABLE The green-yellow wire is a chassis safety ground and must always be connected to the safety ground of the AC mains.
5 EXHIBIT INSTALLATION AND SETUP 6 SETUP 1) Connect the RF-Input connector from the ALPIN 200 to the Transceiver Antenna Port (TRX IN/Out). 2) Connect a suitable antenna or artificial load being able to handle the output power delivered by the ALPIN 200. 3) Connect the PTT – Line from your transceiver to the RELAY jack of the ALPIN 200. The voltage on the Relay Jack is 12V and the current to ground is 11mA.
5 EXHIBIT INSTALLATION AND SETUP 1.3. TRANSFORMER !!! ATTENTION !!! To avoid any damages, please remove the transformer before shipping. ASSEMBLING AND DISMOUNTING It is very easy to assemble or to remove the plug-in transformer. There are only very few connections and screws to other parts of the amplifier.
5 EXHIBIT INSTALLATION AND SETUP 8 1.4. ANTENNA The ALPIN 200 is able to match antennas up to an SWR of 1:3 (16..150 Ohms). It is very important to take a suitable cable (RG213 or better) with a diameter as large as possible for connecting the antenna. All the rest ( i.e. : cable, antenna, balloon…) behind the RF output jack of the amplifier should be able to resist 1 kW RF power. You have to make sure about this before you start operating with the ALPIN 200.
5 EXHIBIT OPERATION 9 2. OPERATION 2.1. FRONT PANEL The front panel is divided into two parts: One for tuning and band switching (left) and another for the visualization.(right) The tuning part consists of a TUNE, LOAD and BAND knob. In the visualization part there are three buttons: STBY/OPR, DOWN and UP for standby/operate switching and display control.
5 EXHIBIT OPERATION 10 While the amplifier is heating up, the protection system will monitor all the important data. Please have a look at page 15 for more information. 2.3. STANDBY MODE When the warming-up time is over, the ALPIN 200 will move to standby mode. Here you can see the forward power for the first time, the reflected power, and the CAP meter. The fourth row of the display is used to show individual and /or the most essential values of the amplifier.
5 EXHIBIT OPERATION 11 2.5. ELECTRONIC BIAS SYSTEM (EBS) only ALPIN 200 MK II The amplifier has an integrated EBS which can be activated and deactivated after switching on. The buttons UP and DOWN have to be pressed down while pressing the LINE switch on the backside. After this the display will show the message “EBS is on” or “EBS is off”. The status can be changed by doing this procedure again. The default configuration is an activated EBS. 2.6.
5 EXHIBIT OPERATION 12 2.7. TUNING EXAMPLE You can find an example of the tuning procedure below. The LOAD TUNIG KNOB has to be rotated clockwise. While rotating the LOAD capacitor the CAP METER is close to the optimum tuning point. We are next to the optimum point. Just a small correction of LOAD and TUNE will be necessary to reach the point. Here, we have found the optimum point for the LOAD Capacitor. Now we can release the PTT and increase the drive power.
5 EXHIBIT OPERATION 13 2.8. TUNE TABLE The table below shows the approximate settings for the TUNE and LOAD knobs on each band. These settings are not exact but they can give you a starting point for a faster tuning of the amplifier. Band 1.8 3.56 7.05 10.1 14.25 18.15 21.25 24.92 28.5 50.2 Tune 66 29 49 15 44 87 39 57 22 15 Load 85 48 81 30 38 81 56 54 39 14 These settings will vary from one amplifier to another.
5 EXHIBIT PROTECTION SYSTEM 14 3. PROTECTION SYSTEM This amplifier uses a very complex protection system. If an error occurs, the amplifier switches to standby or off mode and prints an error code to the display. In this way, the protection system is able to avoid a series of potential damages to the amplifier, but there is no reason to operate carelessly. 3.1.
