Analog Clock Connection and Use

Up to 10 Radio Systems AC-12 analog clocks can be directly connected to any

CT-2002 Master or GPS driver board. If more than 10 clocks are to be utilized,

they may be connected via the AMD-1 analog clock driver. Analog clocks con-

nected to the GPS Master driver will automatically be updated for Daylight

Savings Time and Standard Time. Clocks wire via a 3-wire cable, and can be con-

nected in a “home-run” or “round-robin” wiring array to the driver.

To connect analog clocks to a CT-2002 Master unit, consult the “Connections to

the CT-2002 Clock/Timer” diagram for wiring instructions. To connect analog

clocks to a CT-2002 GPS unit directly or with an AMD-1 booster driver in-line,

consult “Connections to the CT-2002 GPS Driver” diagram on page 23.

Initial Time-of-Day setting

1. Set your CT-2002 Master or GPS unit to the correct time. Press Stop/Start till

display blinks. Then press mode button 12:00:00 is displayed. This is the

“Set” position.

2. Set digital clock to future time that all analog clocks are going to be set to.

Stop=Hours. Reset=Minutes. Do Not Start Clock At This Time.

3. Connect the analog clock and start it running (if it has not started on its own)

by pushing the STOP/START button on the rear of the analog clock.

4. Stop the second hand exactly as it rests on the “12” by pushing the

STOP/START button on the rear of the analog clock again.

5. Set the hour and minute hand for a time several minutes ahead. Save time set

on frozen digital clock.

6. Repeat this process for any additional clocks in the system, setting all clocks

for exactly the same time.

7. When the digital display reads exactly the time of day set on the analog

clocks, push the START button on the CT-2002 Master, GPS Master, or AMD-1

Master driver unit being utilized in your system. All clocks should start and

run together.
