It also contains information on the plugs, jacks, sockets and pins that make up the cable assemblies in the Exciter Switcher. Single Channel Exciter Switcher, LX Series (1305715) System Description - Page 1 of 1 - The Single Channel Auto Switcher consists of (A1) a Single Channel Exciter Switcher Tray (1305715) with a separate (A2) coaxial transfer relay, mounted on a bracket that faces toward the rear of the cabinet, behind the Switcher Tray. The Exciter Switcher Tray is designed to monitor the selected On Air Exciter and automatically switch to the back up Exciter if the On Air Exciter should malfunction. The coaxial relay has the RF outputs from both Exciters connected to its inputs and, depending on if the energizing voltage is applied or not, the selected Exciter RF Output is connected to the external amplifiers and the RF output from the other exciter is connected to a load. Functionally the Single Channel Exciter Switcher Tray contains an Exciter Switcher Control Board (1305704), which provides the monitoring of the operation of both Exciters and the control of the automatic switching of the Exciters in case of malfunction in the On Air Exciter. ICs on the board monitor the operating parameters of the Exciters and determine if the Exciters are functioning properly. The front panel of the Exciter Switcher has an LCD display, which provides set up screens for the operation of the switching process. The coaxial relay has four “N” connectors that provide input and output connections to the relay. The RF Output from Exciter “A” connects to J21. The RF Output from Exciter “B” connects to J23. The Selected Exciter RF Output to the external amplifiers connects to J24. The Exciter “A/B” Load connects to J22, to which the RF output of the Off Air Exciter is connected. A wire harness connects to the relay from J14 on the Exciter Switcher Control Board. These connections provide the control voltages to the relay from the control board and status indication connections back to the control board. This Instruction Manual contains the Schematics, Interconnects, Assembly Drawings and Replacement Parts Lists needed for the troubleshooting of the Exciter Switcher. The Manual also contains information on the operation and maintenance of the Exciter Switcher. Single Channel Exciter Switcher, LX Series (1305715) Installation Procedure - Page 1 of 1 - NOTE: If the Single Channel Exciter Switcher is already installed as part of a Transmitter System then this section may be skipped. Remove the (A29) Exciter Switcher with the Exciter Switcher Board (A1), the Relay Panel (A2), all cables and the wire harness from the shipping box. Remove the packing material from around the Switcher and any accessories and inspect them for damage. Notify Axcera and the shipper if damage is found. The Exciter Switcher is designed to fit into a standard 19" rack normally between the two Exciters to be controlled. Mount the Assembly to the rack using the hardware found in the Installation Material Kit. Refer to the Single Channel Exciter Switcher Interconnect (1305739) and the system Interconnect (1305741 for 5 kW) while installing the wire harness and cabling to the proper Jacks and connectors. The following RF connections are made using RG-55 cables. Locate the cables labeled for the each of the following connections and physically make those connections. Labeling for the transmitter system is as follows: (A27) Exciter A, (A28) Exciter B, (A29) Exciter Switcher, (A30) Load, (A15) 2 Way Splitter then to (A5) on of the 4 Way Splitters, two are used in a 5kW system. (A2) Transfer Function Relay From\To (A27) Exciter A RF Input A29-J21 Exciter A RF Output A27-J25 (A30) Exciter A/B Load Output A29-J22 To Exciter A/B Load A30-J1 (A28) Exciter B RF Input A29-J23 Exciter B RF Output A28-J25 Selected Exciter RF Output A29-J24 To RF Splitter (A15) in 5kW Refer to the Single Channel Exciter Switcher Interconnect (1305739) and the system Interconnect (1305746 for 500/1 kW) while installing the wire harness and cabling to the proper Jacks and connectors. The following RF connections are made using RG-55 cables. Locate the cables labeled for the each of the following connections and physically make those connections. Labeling for the transmitter system is as follows: (A2) Exciter A, (A12) Exciter B, (A14) Exciter Switcher and (A15) Load. (A2) Transfer Function Relay From\To (A2) Exciter A RF Input A14-J21 Exciter A RF Output A2-J25 (A15) Exciter A/B Load Output A14-J22 To Exciter A/B Load A15-J1 (A12) Exciter B RF Input A14-J23 Exciter B RF Output A12-J25 Selected Exciter RF Output A14-J24 To the (A3) Power Amplifier Assembly The Exciter Switcher is ready for AC connection. Remove the AC Line Cord from the Installation Material Kit and install onto Jack J1 on the Exciter Switcher. Connect t…
