Important:
If a dropping resistor is necessary, a good value to try is 5 Ω/10 Watts. This
resistor will need to be placed inline on one of the motor control lines anywhere
in between the controller and the antenna. If you are not sure whether or not this
resistor is necessary for your antenna, try it and inspect the torque and speed of
the motor. If the motor is too slow, reduce or eliminate the resistance. Use of
12 volts with a 3 or 4-volt antenna will result in failure of the motor.
WARNING:
4. Connect the RF sensor inline with the Antenna's RF Feed Line.
5. Connect the supplied Cat 5E cable from the Sensor's Remote Jack to the
Controller's Remote Jack.
Checking operation:
1. Switch controller to on.
The Display will read F=000 P-0
Note: The motor control current limit is set for 2 Amps. This could be too
much for some antennas. The current limit can be change in the TRIP menu to
match the antenna requirements. See Instruction under TRIP for more details.
2. Press the UP Button and release while watching the display. A letter U
should appeared to indicate the antenna is moving up and the turns counter
(pulse) represented by the letter P should have been counting. The C will
indicate the current of the antenna's motor.
3. Press the Down Button and release while watching the display. A letter D
should appear and the counter (P) should have been counting down. The C will
indicate the motor's current.
A TRIP indication means the motor current is higher than the menu trip current
setting.
The current limit will need to be set to a higher current.
Instructions under TRIP for details.
Failure to adjust and operate your screwdriver
antenna at the proper voltage will damage the
antenna motor.
Do not apply voltages greater than 18 volts to this unit, or
permanent damage to the unit and antenna may result.
