The transmitter circuitry is subdivided into four basic stages: Ac-Dc Power Stage Control/Excitation Stage - see page 2.1.4 RF Stage - see page 2.1.5 R efer to the functional block diagram, Figure 3.1.1 on page 3.1.9. VX150 to VX2 Electrical Schematics Some descriptions in this section refer to electrical schematics (SD-#s). These are located in Section 4 of the VX150 to VX2 Troubleshooting Manual. Ac-Dc Power Stage See electrical schematic Figure SD-1. The ac-dc power stage provides power to operate the low voltage power supply, which generates the +12 dc voltage that is used throughout the transmitter. This supplies the voltage to operate cooling fans, IPA and power the PWBs. The ac-dc power stage also contains a dc power supply that provides positive dc voltage (PA volts) f or the transmitter's RF power amplifier. The output voltage range of the dc power supply varies with the model. F or VX150 to VX600 transmitters, the output voltage range is between +18 and 53 V dc. For VX1to VX2 t ransmitt ers, the output voltage range is between +23 and 65 V dc. For normal operation, VX150 to VX600 transmitters accept a single-phase, 90 - 265 V ac (220 V ac nominal) ac input voltage. For normal operation, VX1 to VX2 transmitters accept a single-phase, 185 - 265 V ac (220 V ac nominal) ac input voltage. NOTE : VX1 to VX2 transmitters can operate from a 90-185 V ac input, but will have reduced output power. The ac-dc power stage consists of Power Supply Interface PWB (A4), low voltage power supply (LVPS) ( U2) and power supply (U3). VX150 TO VX2 OPERATIONS & MAINTENANCE MANUALDESCRIPTION PAGE 2.1.2VERSION 0.2 2021-01-14 Power Supply Interface PWB See electrical schematic Figure SD-1. The Power Supply (PS) Interface PWB (A4): interfaces between the ac input and the LVPS and the power supply. distributes LVPS voltage to the RF drive (exciter) stage and the control/monitor stage. distributes PA voltage to the RF power stage and the control/monitor stage. controls, with the controller module, the LVPS output voltage. provides RS485 serial communication between the system interface PWB and the power supply. provides status and alarm outputs from the LVPS and power supply, consisting of Module Present, Power Fail Warning, Rectifier Fault and Overtemp Warning (provided to the Module Control/Interface PWB over a serial bus). Low Voltage Power Supply See electrical schematic Figure SD-1. LVPS module (U2) converts the ac input voltage to the regulated output (+12 V dc). This voltage is used to power all the PWBs, the cooling fans and the IPA. Power Supply Modules See electrical schematic Figure SD-1. Power supply module U3 converts the ac input voltage to a regulated dc supply (PA volts) for the RF amplifier and provides an output voltage between 18 V and 53 V for the VX150 to VX600, and between 23 and 65 V dc for VX1 to VX2). The modules regulate the output voltage based on a serial control input from the Power Supply Interface PWB (A4). The supply also senses out-of-regulation on the ac input and dc output, and applies a Power Fail Warning signal to the Exciter PWB. Both conditions cause the power supply to shut itself down, thus shutting down the transmitter's RF output. All power supply module signals are applied to the exciter for system level…

This section includes the following topics: Corrective Maintenance Electrostatic Protection - see page 3.1.3 Identifying and Troubleshooting an Alarm - see page 3.1.4 Replacement Procedures - see page 3.1.17 If none of the procedures and alarms described in this section address your problem, contact Nautel for assistance. See “Technical Support” in the Installation Manual. Corrective Maintenance Corrective maintenance procedures consist of identifying and correcting defects or deficiencies that arise during transmitter operation. Local and/or remote alarm signals are generated when a malfunction occurs. If an alarm condition is caused by a malfunction in the RF power stage, the transmitter may maintain operation at a reduced RF output level. The nature of the fault – and station policy – will dictate whether an immediate maintenance response is necessary. Fault analysis and rectification may be conducted from three different levels, with a different technical competence level required for each: on-air troubleshooting, remote or local, and off-air troubleshooting. On-Air Troubleshooting On-air troubleshooting can be performed from a remote location, or locally at the transmitter site. Remote Troubleshooting Remote on-air troubleshooting consists of monitoring the transmitter's radiated signal using an on-air monitor or via a LAN connection, and observing the status of each remote fault alarm indicator. Information obtained from these sources should enable an operator to decide whether an alarm response may be deferred to a more convenient time, an immediate corrective action must be taken, or CAUTION! The transmitter contains many solid state devices that may be damaged if subjected to excessive heat or high voltage transients. Take every effort to ensure that circuits are not overdriven or disconnected from their loads while turned on. VX150 TO VX2 TROUBLESHOOTING MANUALRESPONDING TO ALARMS PAGE 3.1.2VERSION 0.1 2020-12-01 if a standby transmitter must be enabled (if one is available). It is recommended that the significance of remote indications, and the appropriate responses, be incorporated into a station's standard operating procedures. Refer to “Identifying and Troubleshooting an Alarm” on page 3.1.4 to determine the remedial action required for a given fault. Local Troubleshooting Local on-air troubleshooting consists of monitoring the transmitter's integral meters and fault alarm indicators. Analysis of this data will normally identify the type of fault, and in most cases will determine what corrective action must be taken. Refer to “Identifying and Troubleshooting an Alarm” on page 3.1.4 to determine the remedial action required for a given fault. Off-Air Troubleshooting Off-air troubleshooting must be performed when routine on-air calibration adjustments will not restore operation. It is recommended that the transmitter’s output be connected to a precision 50  resistive dummy load (rated for at least the maximum transmitter power rating) before starting off-air troubleshooting procedures. If an appropriate dummy load is not available, troubleshooting for a majority of faults can be performed with RF power turned off. The transmitter may remain connected to its antenna system for these procedure…
