Installation And Setup Checklist - Dawn CONTROL-1500A Manual

CONTROL-1500A Single Axis Antenna Controller
(also referred to as 'return') and the other side connected to the AutoPol input. When the relay
is active the AutoPol input is connected to ground - a low level input. When the relay is
deactivated, the relay contacts open and the AutoPol input floats high due to the controller's
internal pull-up resistor.
Here is the procedure for installing and configuring the AutoPol feature:
1. Identify an output on the receiver which can be used to drive the AutoPol input on the
CONTROL-2000C. Note if a high level output corresponds to V polarization or H polarization.
2. Connect the AutoPol input as shown in figures 3.2 or 3.3.
3. Go to CONFIG mode, use the Scroll Up/Down keys to bring up the AutoPol Enable prompt.
Key in 1 followed by the Enter key.
4. After the AutoPol Enable item is configured, the user will be prompted to enter the AutoPol
VLevel Config item. If a high level output from the receiver corresponds to vertical
polarization, key in 1 followed by the ENTER key. If a high level corresponds to horizontal
polarization, key in 0 followed by the ENTER key.
5. Go to Manual mode and verify that the AutoPol feature works properly. When the AutoPol
feature is enabled, in Manual mode, an 'a' is displayed in the third character position after
the polarization position field (this will be the twelfth character from the left on the top row of
the LCD). When AutoPol is disabled, the field will be blank.

Installation and Setup Checklist

This section gives a summary of the installation and configuration procedure outlined in this
chapter. The summary is presented in the form of a checklist.
1. Before power is applied verify that the line voltage is correct. Check the sticker over the
power entry module.
2. Make sure that the memory has been cleared. The controller should come up in LIMITS
mode.
3. Make the required electrical connections. Shielded cable must be used for the position
sensors and the shields must be connected at the back of the controller and NOT at the
antenna. If the sensor cable is spliced, the drain wire must also be spliced an must not
be allowed to come in contact with ground. Refer to figures 3.1, 3.2, and 3.3.
4. If the RC2KPOL option (which allows the CONTROL-1500 to interface to a 24 volt DC
polarization control motor) is installed, make the required electrical connections for the
motor and sensor, verify the polarity of the motor and the position feedback sensor, and
set the polarization limits. Make sure that when the CCW key is depressed to jog the
polarization motor counter-clockwise, the displayed position count INCREASES. Use
caution to avoid damaging the potentiometer.
5. Go to Limits mode and verify the antenna motor drive polarity. Set the antenna limits.
