Section V Theory of Operation
PINEAPPLE TECHNOLOGY, INC. UTX2.5K ULTRA Operating and Service Manual V -- THEORY OF OPERATION V --- THEORY OF OPERATION (Page 1 of 5) A. INTRODUCTION The UTX2.5K ULTRA transmitter was designed to meet or exceed all FCC applicable specifications for TV broadcast equipment. Special attention was given to the selection of sub-assemblies and components to achieve maximum reliability and minimum down time. The construction of the UTX2.5K ULTRA is BASIC and MODULAR with most components field replaceable.
PINEAPPLE TECHNOLOGY, INC. UTX2.5K ULTRA Operating and Service Manual V -- THEORY OF OPERATION (CONTINUED) (Page 2 of 5) The power modules are "HOT PLUGGABLE" and can be removed or installed without turning off the transmitter. Each power supply module has OVER VOLTAGE, OVER CURRENT AND OVER TEMPERATURE protection as well as a fault signal in the event of a failure. REFER TO MANUFACTURER'S MANUAL FOR MODEL # TWRI6004 PROVIDED WITH THE UTX2.5K ULTRA. D.

PINEAPPLE TECHNOLOGY, INC. UTX2.5K ULTRA Operating and Service Manual VIII -- ADJUSTMENTS AND TUNING VIII --- ADJUSTMENTS AND TUNING (Page 2 of 2) 4. PA PALLETS - These circuits are "FIXED TURNED" and do not require any field adjustment. Any questions regarding pallet adjustments should be referred to the factory. 5. PHASE MATCHED CABLES - If it becomes necessary to replace one of the phase matched cables, contact Pineapple Technology, Inc. for replacements.
Section IX Problem Solving & Troubleshooting
PINEAPPLE TECHNOLOGY, INC. UTX2.5K ULTRA Operating and Service Manual IX -- PROBLEM SOLVING/TROUBLE SHOOTING IX - PROBLEM SOLVING & TROUBLE SHOOTING (Page 1of 3) The UTX2.5K ULTRA is a "MODULAR ASSEMBLY" where most of the sub-assemblies can be removed and or replaced as necessary to maintain full service. To service this transmitter, it is best to become familiar with the various sub-assemblies by reviewing the transmitter block diagram and it's associated subs shown in the introduction.
PINEAPPLE TECHNOLOGY, INC. UTX2.5K ULTRA Operating and Service Manual IX -- PROBLEM SOLVING/TROUBLE SHOOTING IX - PROBLEM SOLVING & TROUBLE SHOOTING (Page 2of 3) SHUTDOWN RED indicates that the PA has been "SHUTDOWN". There are two possible reasons for this: 1.
PINEAPPLE TECHNOLOGY, INC. UTX2.5K ULTRA Operating and Service Manual IX -- PROBLEM SOLVING/TROUBLE SHOOTING IX - PROBLEM SOLVING & TROUBLE SHOOTING (Page 3 of 3) PA1 - PA5 LED's are RED This will indicate that the PA Pallet currents are below the 500 ma set point. This can occur when the PA Power device has failed. CHECK 1: Select the PA device in question for current display on the multi-meter. Compare the reading to the station log. If abnormal, it is possible that a power transistor has failed.
