10. S INDICATORS The coax switch position status indicator pairs and flow chart graphic indicate the transmitters signal path to antenna or load The switch position number that corresponds to main transmitter on air depends on which ports the transmitters and antenna or dummy load have been connected to A logic reverse jumper is described in the switch position tally paragraph in the connections section of the manual LOAD INTERLOCK With fan cooled or water loads the tally contacts in the load will allow the off air transmitter to run through the controller s load interlock circuit When the load is on the front panel dummy load indicator is on for testing transmitters With convection loads an external switch should be connected to the load interlock terminals If a transmitter change command is given during a load test the coax switch is protected because both transmitters will be muted FUSES The rear panel DC fuse 1 2 A is on the output of the 24V power supply The AC fuse is in series with the hot lead for the entire controller and the AC power for the coax switch This fuse should be about 3A with Dielectric 50000 switches The installer may choose to use larger fuses The controller s internal power wiring is 18 ga AUTO TRANSFER The optional key switch selected auto transfer will change to transmitter 2 if transmitter 1 fails To use auto transfer the controller requires a continuous signal to indicate that transmit

25. r both transmitters will be muted while the switch is moving With a convection load an external switch should be connected to the load interlock terminals A switch is usually preferable to a permanent jumper so that when the site is unattended the off air transmitter is not allowed to run into the load An external load interlock switch might also be desirable with Altronic loads This is due to the nature of their tally contact operation whenever power is applied their tally contacts close and will open only if the load overheats This could allow operator error to turn on an off air transmitter While the load would theoretically not be damaged the heat from the extra transmitter and the load could cause problems in many transmitter buildings given some time As an alternative to an external load interlock switch the Altronic load could be disconnected from power when the site is unattended PLATE ON AND OFF CONNECTIONS Plate on and off closures have been added to the standard TRC 1 to make the TRC 1P Terminals TB2 1 to TB2 8 are the 4 closures The plate off closures are momentary and operate immediately when either transmitter change command is issued The plate on closures are momentary and operate when the switch sequence is complete at the same time the transmitter interlock is restored SWITCH POSITION TALLY CONNECTIONS The controller needs to know which position the coax switch is in to operate the transmitter inter
