D: 02/01/96 DESCRIPTIONPrint Date: 12/17/96 Copyright © 1996 Glenayre Page: 3-1 3 DESCRIPTION 3.1 Introduction The Gold Line 50-A and 90-A power supplies are part of a radio paging transmitter. The50-A version is used in the GL-T8500 transmitter; the 90-A version is used in the GL-T8600 transmitter. The supplies provide power to other assemblies within the rack,including cooling fans.Refer to Table 3-1 Gold Line Power Supply Options for more information.3.2 Physical Description The supply chassis must accommodate more than one type of equipment rack. Accordingly,the assembly may vary slightly for proper cooling and mounting requirements. Weightvaries with supply configuration. Also refer to Table 2-1. Figure 3-1, Front View of GoldLine 50-A Power Supply shows the front of the power supply, and Figure 3-2, Top Viewof Gold Line 50A Power Supply shows a view of the power supply from the top.3.2.1 Mounting ProvisionsThe power supply is mounted in a standard 19-inch rack. Some rack cabinets do not haveequipment access from the back; others do. The steel supply chassis has no top or sides.The protective front cover attaches to the front rail of the rack cabinet. The chassis is foldedon the bottom to allow it to slide between the rack-cabinet floor and two floor-mountedbars. The chassis is held in place with two bolts that attach to the rack cabinet through thelower front edge of the chassis. The supply is mounted at the bottom of the equipment rackin all single-transmitter configurations.The supply requires little cabinet space. Refer to Figure 3-1, Front View of Gold Line50-A Power Supply for detail. The front panel of five RUs (8.75 in) in height contains acircuit breaker and fuses. Figure 5-1, Gold Line 50-A Power Supply Front-PanelControls and Indicators shows and describes their functions.

It is electrically protected by circuit breaker CB1. There are taps on theprimary of the power transformer to allow various ranges of input voltage.Output is rectified by CR1 and CR2, and filtered by C2, C3, and C4, and C5 to provide afiltered, stable dc output. Dc output for the PA is cabled directly from the filter capacitorassembly to terminals mounted on the side of the equipment rack. Dc for the exciter,receiver, controller, fans, and auxiliary equipment is routed through plug J1. 6.2 Voltage Regulator Assembly Refer to Figure 6-3.The 13.5-volt output of voltage regulator IC U1 is set by the values of R1 through R3. Asso-ciated components filter and protect the assembly from damage due to electrical transients.

D: 02/01/96 CHECKOUT AND TROUBLESHOOTINGPrint Date: 12/17/96 Copyright © 1996 Glenayre Page: 8-1 8 CHECKOUT AND TROUBLESHOOTING 8.0.1 Test Equipment and Tools Required Common hand tools are required for assembly and disassembly. An RFI-immune voltmeteris required to measure dc voltages. 8.0.2 Precautions Follow all danger advisories in paragraph 9.1, as ac power is applied to equipment duringsome tests. Only qualified technicians should perform these service items.8.0.3 Resonator Capacitor Check With main power applied, connect a dc meter across the supply dc output. Level should be24-27 Vdc. .This check is complete. 8.0.4 Transformer Check With ac input power applied, connect an ac meter across the secondary winding of thetransformer. Approximately twice supply voltage (50 Vac) should be present. This check is complete. 8.0.5 Diode Check With power off, disconnect each diode from the heat sink. Check with ohmmeter in diode-checking mode from each diode anode to the heat sink;normal dc conduction should be present from each one. This check is complete.

D: 02/01/96 REMOVAL AND REINSTALLATIONPrint Date: 12/17/96 Copyright © 1996 Glenayre Page: 9-1 9 REMOVAL AND REINSTALLATION 9.1 Precautions and Hazards DANGERThe power supply chassis is not protected by interlocks. Disconnect ac power before removingany covers.DANGERThe power transformer is heavy. Follow precautions for heavy lifting. 9.2 Test Equipment and Tools Required Common hand tools are required for assembly and disassembly. An RFI-immune voltmeteris required for voltage measurement. 9.3 Ac Voltage Change If the power supply or power transformer is replaced, the expected input voltage must beset before ac power is applied. Refer to the installation in Section 4.9.4 Component Locations Regarding component locations in the 50A supply, see Figure 3-1, Figure 3-2, andFigure 7-1.Regarding component locations in the 90A supply, see Figure 3-3, Figure 3-4, andFigure 7-2.9.5 Chassis Removal and Reinstallation Heed all danger references at the beginning of this section. Refer to Figure 9-1, PowerSupply Removal and Reinstallation from/into rack throughout this procedure.The 90Apower supply picture is similar except it has four capacitors instead of two.

D: 02/01/96Page: 9-2 Copyright © 1996 Glenayre Print Date: 12/17/969.5.1 Removing Chassis from Rack Perform the following steps to remove the chassis:1. Disconnect primary power to cabinet before continuing.2. Remove the front cover; it is held by several machine screws.3. Remove two bolts in bottom-front of supply chassis.4. Pull chassis out of rack enough to access electrical connections.5. Disconnect wiring harness plug.6. Remove dc cables from filter capacitor gridwork. 7. Disconnect 3-conductor power cable from rear-mounted TB1.8. Remove supply from rack carefully.This procedure is complete. 9.5.2 Reinstalling Power Supply into RackInstalling the supply is done by performing the following steps:1. Set the supply partially into rack.2. Connect dc cables to capacitor gridwork. 3. Reconnect 3-conductor power cable to rear-mounted TB1.4. Reconnect wiring harness plug.5. Push supply into rack; be careful not to damage any wiring.6. Secure supply with two bolts in bottom-front edge of chassis.7. Secure front cover with machine screws.This procedure is complete.9.6 Removing and Reinstalling the 13.5-Volt RegulatorIf it becomes necessary to replace the 13.5-volt regulator, perform the following proce-dures. Refer to Figure 9-2, 13.5-Volt Regulator Board Removal and Reinstallationthroughout these procedures. It is assumed that the power supply chassis has been removedfrom the rack.

Remove connectors from J1 and J2. 3. Note arrangement of hardware on mounting screws and transistors. Replacing parts in correct order is essential to successful assembly replacement.4. Remove screws from heat-sink-mounted transistors.5. Remove screws from On edges of pc assembly so that assembly comes loose from standoffs..6. Remove assembly9.6.2 Reinstalling 13.5-Volt Regulator1. Check insulators between transistors and heat sink for damage. Make sure that insula-tors are undamaged and have adequate thermal compound on both sides and that no grit or other foreign substances are embedded in thermal compound.2. Place regulator assembly on standoffs by heat sink. 3. Replace screws which mount pc board to standoffs.4. Replace screws and hardware to attach transistors to large heat sink. 5. Reattach electrical connections to J1 and J2.
