It is used for control, status and monitoring of all PA Module parameters and for the reporting of Module faults. As a backup to this serial control network, each PA Module has dedicated hardware control lines for functions such as On, Off, Restart and RF Mute.

    Section 2 Installation / Initial Turn-On ATLAS Analogue 2.5.3 Continue Cooling System Installation Connect the control and status wires between the cooling control panel and the transmitter with the supplied multi-conductor cable. These low level signals connect from terminals X2-1 through X2-12 in the cooling control panel to J12-1 through J12-12 on the External I/O board in the transmitter (pin for pin connection).
  • Page 45 Section 2 Installation / Initial Turn-On ATLAS Analogue If there is a temperature overload switch on the test load, (as would be the case for an air cooled load) it should be connected to J18-11 and J18-12. This open interlock contact will mute the transmitter RF output if the test load temperature threshold is exceeded (while the transmitter is operating into the test load).

  • Page 46: Transmitter Ac Connection

    A safety ground wire is required and connects to E2 which is shown in Figure 2-2 on page 2-17. The Atlas Analogue transmitters are 3 phase 208/220/240Vac or 3 phase 380/400/ 415Vac at 50/60Hz delta or wye. If voltage variations in excess of ±10% are anticipated, the transmitter power input must be equipped with automatic voltage regulators (optional equipment) capable of correcting the mains voltage.

    Section 4 Theory of Operation ATLAS Analogue the single ended CAN controller to the differential CAN bus for high common mode noise immunity, as shown in Figure 4-2. All of the control boards can send and receive information over the differential CAN bus, however the Main Controller determines what information is sent and when it is sent for this application.

  • Page 121: Parallel Control Lines

    Section 4 Theory of Operation ATLAS Analogue 4.3.4.1 Parallel Control Lines The parallel control lines are used for quick actuation of critical functions, such as ON, OFF, RF mute, PS mute, AC_Low and Fault Off. These lines are also the backup control lines in Life Support mode when the Main Controller (and therefore the CAN bus) is not operational.

  • Page 122: Main Controller

    Section 4 Theory of Operation ATLAS Analogue e. /PS_MUTE The /PS_MUTE line shuts down the output of the 32 Volt PA module supplies temporarily until the fault condition is cleared. This is a non-latching signal. The Main Controller, Power Block Controller, External I/O and RF Monitor Boards monitor this line and have the ability to activate it if necessary.
