Chapter 3 Installation/Setup; Before You Begin - Dawn CONTROL-1500A Manual

CONTROL-1500A Single Axis Antenna Controller
This chapter guides the installer through the mechanical and electrical installation of the
controller as well as initial software setup.
This chapter describes the electrical connectors on the back panel of the controller, cabling
requirements, installation of optional polarization control devices, antenna limits, and
configuration of the antenna slow speed system.

Before You Begin

Before installing the unit the installer must ensure that the controller's line voltage setting is
correct, the controller's memory has been cleared, and that he or she is familiar enough with
the mode system described in Chapter 2 to place the controller in any desired mode.
The CONTROL-1500 can be configured to operate on either 115 VAC or 230 VAC. The AC line
input voltage the unit is currently configured for is displayed in a window located in the fuse holder
that is built into the IEC power entry module on the back panel of the controller. To change the
AC input voltage selection, remove the fuse holder and reverse the jumper assembly (on which
the '115' and '230' labels are located). The fuse holder is designed to accommodate 1/4" by 1
1/4" fuses. The CONTROL-1500 uses a 5 amp slow blow type fuse. Bussman MDA-5 OR
Littlefuse type 3AB series 326, p/n 326 005.
When the AC line voltage has been verified, before the controller is interfaced to the antenna
the installer should become familiar with the controller's user interface. It is not necessary to
understand every aspect of the controller's operation to install the unit, but the installer should
be familiar with the mode structure of the CONTROL-1500 and be able to use the MODE key to
place the controller in any of the modes described in Chapter 2.
After the AC line voltage is verified and the user has become acquainted with controller's user
interface the unit may be powered up. When the unit is powered up, it should be verified that
the controller goes to LIMITS mode ('LIM' displayed in the lower right hand corner of the LCD).
Before the controller is shipped from the factory, the memory is cleared and the controller's
logical limits are invalidated. Whenever the unit is powered up and the limits are invalid, the
controller automatically places itself in LIMITS mode. Note that there may also be a limits
alarm message flashing on the bottom row of the display.
If the unit does not power up in LIMITS mode the installer should perform a system reset to
place the controller into a known state before proceeding with the installation.
To perform a system reset:
1. Use the MODE key to place the controller into CONFIG mode ('CFG' displayed in the lower
right hand corner of the LCD).
2. Use the SCROLL keys to bring up the Reset Sys screen. If the Reset Sys item does not
appear, the Expert Access flag (see section 2.5) may need to be reset.
To inspect the status of the Expert Access flag, use the SCROLL DOWN key (while still in
CONFIG mode) to bring up the Expert On CONFIG mode item. If a 1 does not appear in
