REJECT LOAD INTERLOCK CONNECTION If the reject load has an overheat tally contact that opens on overheat it can be connected between TB6 1 common and 6 9 to shut down transmitters 1 and 2 in combined modes The reject load interlock has no effect in separate modes There is no timeout transmitter interlocks will close immediately when the reject load interlock is restored If the reject load interlock is not used a jumper is required between TB6 1 common and 6 9 or transmitters 1 and 2 will not run in combined modes OPERATION From a single local or remote command the controller operates the transmitter interlocks and switch motors in a timed sequence such that the switches are never moved with RF power applied The transmitters are interlocked or muted before the switch motors are energized Other functions include optional automatic transmitter transfer in case of failure plate on and off control and transmitter load testing ANTENNA SYSTEM MODES The first 4 front panel pushbuttons are the local controls for Combined Antenna Combined Load Separate TX 1 Separate TX 2 Pushing any of these buttons will lock out the other 3 for the duration of the switching sequence The switching sequence is transmitter interlock connections open and plates off a short delay to let the transmitters plate supplies discharge coax switch operation as long as it takes up to 30 seconds at completion of switch movement interloc
