This distributes both +24VDC and Ground. The terminals are recessed to minimize the risk of short circuit due to foreign debris. All the contacts are properly coated to reduce the risk of corrosion, and to operate without vibration, which could cause individual contacts to loosen. The unit is an industry standard method for proper distribution of low Voltages. No periodic maintenance is required. ISO 9001:2000 Base Transmitter (Magnetron) 2-9 PROPRIETARY ENTERPRISE ELECTRONICS CORPORATION CHAPTER 2 BASE TRANSMITTER (MAGNETRON) POWER DISTRIBUTION BLOCK ISSUE/REVISION DATE: 12 March 2007 TECHNICAL MANUAL MAGNETRON BLOWER ASSEMBLY Blower Current Motor Hose The Magnetron blower assembly is the typical cooling system for the Magnetron tube. Pictured above is the assembly with the hose and end-bell for use with the EEC Magnetron tubes. Each Magnetron tube type uses a different hose and end-bell arrangement but is similar to the one pictured. A screen shroud is placed over the blower inlet to keep an object from striking the spinning rotor. The blower is capable of moving approximately 250CFM at 1” of backpressure ensuring maximum cooling of the Magnetron tube ISO 9001:2000 Base Transmitter (Magnetron) 2-10 PROPRIETARY ENTERPRISE ELECTRONICS CORPORATION CHAPTER 2 BASE TRANSMITTER (MAGNETRON) End Bell ISSUE/REVISION DATE: 12 March 2007 TECHNICAL MANUAL Pictured above is the Alarm current sensor and alarm circuit board mounted on the Magnetron Blower Assembly. This module monitors the Magnetron blower for proper operation via current flow. If the current drops below a pre-set limit due to either motor failure or other faults, the alarm circuit initiates a controlled shutdown of the transmitter thus preventing damage of critical components. There are no adjustments or other periodic maintenance required. ISO 9001:2000 Base Transmitter (Magnetron) 2-11 PROPRIETARY ENTERPRISE ELECTRONICS CORPORATION CHAPTER 2 BASE TRANSMITTER (MAGNETRON) ALARM CURRENT MONITOR ISSUE/REVISION DATE: 12 March 2007 TECHNICAL MANUAL The temperature sensors used in the base transmitter unit are precision semi-conductor temperature to Voltage converters. Additional circuitry is provided to compensate for cable length and to eliminate pulse noise. Both temperature sensors are fed to the DDC module and the information is used both for BITE data and for transmitter monitoring . ISO 9001:2000 Base Transmitter (Magnetron) 2-12 PROPRIETARY ENTERPRISE ELECTRONICS CORPORATION CHAPTER 2 BASE TRANSMITTER (MAGNETRON) TEMPERATURE SENSORS ISSUE/REVISION DATE: 12 March 2007 TECHNICAL MANUAL DISTRIBUTED DATA COLLECTION MODULE I/O Ports RS232 Ethernet The Distributed Data Collection (DDC) module is an Ethernet, CAN, or serial RS232 controlled device that collects both analog and digital data, as well as controls relays. It outputs TTL signals under processor control. For general information please refer to EEC Publication DDC-ICD and Users manual. For further information refer to the Personality Addendum in the DDC Users Manual. The DDC module controls the base transmitter, Solid State modulator systems, and provides control and monitoring of the temperatures. The DDC also acts as the “gateway” for the Ethernet data stream, providing one component that is the primary data collector and disseminator easing interface programming. The Distributed Data Collection Module (DDC) Interface Control Document (ICD) provides textual detail of the Distributed Data Collection Module (DDC) ISO 9001:2000 Base Transmitter (Magnetron) 2-13 PROPRIETARY ENTERPRISE ELECTRONICS CORPORATION CHAPTER 2 BASE TRANSMITTER (MAGNETRON) Power ISSUE/REVISION DATE: 12 March 2007 TECHNICAL MANUAL TRANSMITTER MAINTENANCE PANEL Two different options for the transmitter maintenance panel exist; one incorporates a pedestal intercom function, and the other doesn't. Both configurations will be shown in this document. Please refer to the FAMILY TREE for your specific unit. • Operate Time Meter – Provides visual display of the hours of operation of the base transmitter unit. This display is typically used to determine the hours of operation of the Magnetron tube filaments. • Radiate Time Meter – Display of hours the unit is in transmit operation. • Trigger Test Jack – Used to trigger external test equipment by the system trigger generated in the base transmitter unit. This trigger is +5VDC positive going. • Forward Detected RF – Connect to an oscilloscope to view the detected pulse of the transmitter. The oscilloscope should have a bandwidth limit set at around 20MHz, or an external low-pass filter with a cutoff of approximately 20MHz should be used for optimum results. For Indication only. See Chapter 6 Maintenance section for Pulse Width Measurement. • Reverse Detected RF – Connect to an oscilloscope to view the detected pulse of the transmitter. The oscilloscope should have a bandwidth limit set at around 20MHz, or an external low-pass filter with a cutoff of approximately 20MHz should be used for optimum results. See Chapter 6 Maintenance section for Pulse Width Measurement. • Ethernet Port – Use for direct Ethernet connection to the base transmitter hub. An external computer with optional EEC software can be connected to this port for transmitter control during maintenance if the optional touch screen interface is not utilized. USB 1 and USB 2 Ports – These ports are used only with the optional touch screen option and allows a mouse and keyboard to be connected. These are not required for regular use of the touch screen, though the user may be more comfortable with this method of control. ISO 9001:2000 Base Transmitter (Magnetron) 2-14 PROPRIETARY ENTERPRISE ELECTRONICS CORPORATION CHAPTER 2 BASE TRANSMITTER (MAGNETRON) The functions of this panel, which are common to both configurations, are run-time meter displays, forward and reverse detected RF, trigger output, Ethernet interface, and USB 2.0 connectors for the optional touch screen computer. The panel is shown below. ISSUE/REVISION DATE: 12 March 2007 TECHNICAL MANUAL TRANSMITTER MAINTENANCE PANEL The optional pedestal intercom incorporates all the functions described above, and adds a headphone jack, push to alert button, a sonic alert device, and RF sample ports for forward and reverse power.

E1 – Chassis Ground J1 – AC Mains Input J2 – Unassigned J3 – J5 – Ethernet Communications J6 – Auxiliary monitoring connector E1 J1 J2 J3 J4 J5 J6 The Base Transmitter I/O Interface Control Document (ICD) provides textual detail of the Base Transmitter I/O Modulator Assembly. ISO 9001:2000 Base Transmitter (Magnetron) 2-16 PROPRIETARY ENTERPRISE ELECTRONICS CORPORATION CHAPTER 2 BASE TRANSMITTER (MAGNETRON) • • • • • ISSUE/REVISION DATE: 12 March 2007 TECHNICAL MANUAL TRANSMITTER SUPPLEMENTAL The Dual Port Power Sensor provides a real time analysis of the transmitted pulse and reverse power. Measuring both forward and reflected power from the waveguide assembly bi-directional coupler allows for indication of the transmitted pulse and the reflected energy. Since reflected energy is also comprised of weather information, the reverse energy is only measured during the transmitted pulse width. If a problem exists in the waveguide, from the transmitter to the feed-horn, this reflected energy will be sensed, and depending on the measured VSWR in the power monitor, the transmitter can be configured to shutdown until the problem is resolved. An LCD display on the front of the power monitor gives readouts of forward power, reverse power, both in dBm and in KiloWatts. The information displayed on the power monitor is also fed to the DDC module for incorporation into the BITE data stream for remote viewing. The power moniter can measure power of RF pulses that are at least 0.4µs in width. For complete information about the various modes of operation and in setting the user parameters please refer to EEC Publications; Dual Port Power Monitor User Manual, and Dual Port Power Monitor ICD.
