Special Tips l Turn on RF power after setting all other parameters l CAN address of exciters and amplifier modules are set in factory, please do not change it. l The transmitter is AGC controlled when CAN AGE in exciter is ENABLED. -
Page 18: Power On Sequence
1 Power On Sequence 1.1 Check all connections l Combiner to dummy load or antenna l Amplifier modules to combiner l Divider to amplifier modules l Switcher to divider l Exciters to switcher l Main exciter to backup exciter... - Page 19 1.4 Set CCU parameters l Turn off RF Switch: RF Switch = OFF l Power Percentage: 0%--100% l Period Control If period control is needed, set three periods first and then enable Period Control (Period Control =Enabled). If period control is not needed, just disable Period Control (Period Control = Disabled).
- Page 20 2 System Control Introduction 2.1 Main Control Function l Data collection and display from 6 amplifiers which include voltage, current, temperature, running status, forward power and reflect power. l Combiner data acquisition and display which include temperature, forward power and reflect power.
- Page 21 Other manufacturer’s exciter can be used but can not be connected on the internal CAN bus network not matter there is a CAN interface or not due to the restriction of the internal communication protocol.
- Page 22 2.3 (CCU) Remote Control CCU has a RS232 interface that can connect to a computer for the remote control purpose. The remote computer can read the following datum: l Equipments’ type and profile, such as nominal power, frequency, number of amplifier modules, maximum power of amplifier module and number of exciters.

Page 23: Rf Output Control
The Automatic Power Control function is enabled when exciter’s CAN AGC is set to enabled, otherwise the system is in Manual Power Control mode. In manual power control mode, the output power is not controlled by CCU (CCU can not control exciter’s power). So, the machine’s output power would be fluctuated with the temperature or other factors change. - Page 24 2.6 System Protection AIn automatic control mode, if RF output power is not able to reach to setting power, it may cause by: l Combiner temperature is above 70. l Combiner’s reflect power is above the warning value (more than 2% of the machine’s nominal power).
