3 DESCRIPTION
3.1 Introduction
The Gold Line 50-A and 90-A power supplies are part of a radio paging transmitter. The
50-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. Weight
varies with supply configuration. Also refer to Table 2-1. Figure 3-1, Front View of Gold
Line 50-A Power Supply shows the front of the power supply, and Figure 3-2, Top View
of Gold Line 50A Power Supply shows a view of the power supply from the top.
3.2.1 Mounting Provisions
The power supply is mounted in a standard 19-inch rack. Some rack cabinets do not have
equipment 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 folded
on the bottom to allow it to slide between the rack-cabinet floor and two floor-mounted
bars. The chassis is held in place with two bolts that attach to the rack cabinet through the
lower front edge of the chassis. The supply is mounted at the bottom of the equipment rack
in all single-transmitter configurations.
The supply requires little cabinet space. Refer to Figure 3-1, Front View of Gold Line
50-A Power Supply for detail. The front panel of five RUs (8.75 in) in height contains a
circuit breaker and fuses. Figure 5-1, Gold Line 50-A Power Supply Front-Panel
Controls and Indicators shows and describes their functions.

3.3 Simplified Description
Ac power flows to power transformer T1; circuit breaker CB1 provides protection against
excess current. The rectified and filtered 25-volt output is supplied to other transmitter
assemblies. The 25-volt output also goes, via fuse F1, to the 13.5-volt regulator board,
which provides 13.5 volts for use by the transmitter.

4 INSTALLATION AND SETUP
4.1 Precautions and Hazards
DANGER
The power supply chassis is not protected by
interlocks. Disconnect ac power before removing
any covers.
DANGER
The power transformer is heavy. Follow
precautions for heavy lifting.
4.2 Test Equipment and Tools Required
Common hand tools are required for assembly and disassembly. An RFI-immune voltmeter
is required for voltage measurement. Also refer to the system manual.
4.3 Component and Adjustment Locations
Figure 5-1, Gold Line 50-A Power Supply Front-Panel Controls and Indicators, shows the
locations of circuit breaker CB1 and the fuses. The only user-setup option is the power-
transformer-input-voltage jumpering.
4.4 Installation
4.4.1 Inspection
Refer to the system manual for inspection information.
4.4.2 Power Requirement
Refer to Section 2 for power specifications.

INSTALLATION AND SETUP Issue 1, Rev. D: 02/01/96
Page: 4-2 Copyright © 1996 Glenayre Print Date: 12/17/96
4.4.3 Input/Output Connections
Table 4-1, Input/Output Connections, shows the connections and functions of I/O connec-
tions for the power supply. The power transformer input must be jumpered for the expected
ac input voltage. Refer to the procedure in this paragraph.
Power supply output connections are made on the filter capacitor assembly inside the
supply. Dc output is cabled directly to the power amplifier chassis. Dc output also goes to
other equipment via a connector and cable. Ac input connections are made directly to
circuit breaker CB1.
Table 4-2, Transformer Connection and Jumpers, shows the connections and jumper
settings for the power supply. The power transformer input must be jumpered for the
expected ac input voltage.

Any added jumper must be of adequate wire size to accommodate current
requirements. Be certain that all transformer connections are tight.
1. Disconnect ac power and remove power supply cover.
2. Remove supply chassis from rack.
3. Locate power transformer T1; identify primary terminals.
4. Refer to
Figure 4-1, Ac Jumpering 100 Vac Nominal,
Figure 4-2, Ac Jumpering 115 Vac Nominal,
Figure 4-3, Ac Jumpering 200 Vac Nominal,
Figure 4-4, Ac Jumpering 230 Vac Nominal,
to configure transformer. Place jumpers for expected line voltage.
5. Reinstall supply chassis into rack; be sure no tools or hardware have been left inside
the power supply.
6. Replace supply cover.

4.4.5.1 Dc Voltage Check
Perform the following steps to check power supply output voltage:
1. With transmitter unkeyed, check voltage at external interface on rack cabinet. Dc
meter reading should be about 26 Vdc.
2. With transmitter keyed (at rated output), check voltage at external interface. Dc meter
reading should be about 24 Vdc

5.1 Front-Panel Controls and Indicators
Figure 5-1, Gold Line 50-A Power Supply Front-Panel Controls and Indicators
shows a view of the front panel, with a description of the operation of the circuit breaker.
The function and ratings of fuses are clearly labelled on the equipment. Note that the fuses
are visible from the front panel. In most cases a blown fuse is obvious by visual inspection.
Note their condition when troubleshooting the equipment.
5.2 Operating Instructions
The power supply operates in an unattended manner during normal system operation. Use
the circuit breaker and fuses when it is necesary to perform maintenance or troubleshooting.
Set the circuit breaker to up position to turn on power supply. Set the circuit breaker to
down position to turn off power supply.

6 THEORY OF OPERATION
6.1 Chassis Components
Refer to Figure 6-1 and Figure 6-2.
Ferroresonant transformer T1 and resonating capacitor C1 act as a reservoir to allow a
constant voltage output despite changing load conditions as long as a constant voltage is
applied to the input. It is electrically protected by circuit breaker CB1. There are taps on the
primary 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 a
filtered, stable dc output. Dc output for the PA is cabled directly from the filter capacitor
assembly 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.

7 MAINTENANCE
7.1 Location of Maintenance Procedures
Most maintenance of electrical assemblies is done via the VT100 interface. Refer to the
system and menu manuals. No maintenance procedures are performed on a regular
schedule. See section 8 of this manual for more information. Refer to Figure 7-1, Gold
Line 50A Power Supply Assembly 265-0082-012 for additional information.

8 CHECKOUT AND TROUBLESHOOTING
8.0.1 Test Equipment and Tools Required
Common hand tools are required for assembly and disassembly. An RFI-immune voltmeter
is required to measure dc voltages.
8.0.2 Precautions
Follow all danger advisories in paragraph 9.1, as ac power is applied to equipment during
some 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 be
24-27 Vdc. .
This check is complete.
8.0.4 Transformer Check
With ac input power applied, connect an ac meter across the secondary winding of the
transformer.
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.
