Section 2 MAINTENANCE1.0 IntroductionThis chapter provides details about the following:

Preventive maintenance (inspection and cleaning). Safe handling of CMOS and LDMOS devices. Repair procedures and techniques.

2.0

Preventive MaintenancePeriodic visual inspection and cleaning is recommended.

2.1

InspectionCheck that the external surfaces of the repeater are clean, and that all external controls and switches are functional. It is not recommended to inspect the interior electronic circuitry.

2.2

Cleaning ProceduresThe following procedures describe the recommended cleaning agents and the methods to be used when cleaning the external and internal surfaces of the repeater. External surfaces include the top cover and repeater enclosure. Periodically clean smudges and grime from exterior enclosure. Use a soft, non-abrasive cloth moistened in a mild soap and water solution Rinse the surface using a second cloth moistened in clean water, and clean any dirt or debris from the fan grill and louvers on the front side. NOTE: Internal surfaces should be cleaned only when the repeater is disassembled for service or repair. The only recommended agent for cleaning the external repeater surfaces is a 0.5% solution of a mild dishwashing detergent in water. The only factory recommended liquid for cleaning the printed circuit boards and their components is isopropyl alcohol (100% by volume). Cleaning Internal Circuit Boards and Components Isopropyl alcohol (100%) may be applied with a stiff, non-metallic, short-bristled brush to dislodge embedded or caked materials located in hard-to-reach areas. The brush stroke should direct the dislodged material out and away from the inside of the repeater. Make sure that controls or tunable components are not soaked with alcohol. Do not use high-pressure air to hasten the drying process since this could cause the liquid to collect in unwanted places. Once the cleaning process is complete, use a soft, absorbent, lintless cloth to dry the area. Do not brush or apply any isopropyl alcohol to the top cover and repeater enclosure. NOTE: Always use a fresh supply of alcohol and a clean container to prevent contamination by dissolved material (from previous usage).

Preventive Maintenance

2.1

Safe Handling of CMOS and LDMOS DevicesComplementary metal-oxide semiconductor (CMOS) devices are used in this family of repeaters, and are susceptible to damage by electrostatic or high voltage charges. Damage can be latent, resulting in failures occurring weeks or months later. Therefore, special precautions must be taken to prevent device damage during disassembly, troubleshooting, and repair. Handling precautions are mandatory for CMOS circuits and are especially important in low humidity conditions. DO NOT attempt to disassemble the repeater without first referring to the following CAUTION statement.

!Caution

This repeater contains static-sensitive devices. Do not open the repeater unless you are properly grounded. Take the following precautions when working on this unit:

Store and transport all CMOS devices in conductive material so that all exposed leads are shorted together. Do not insert CMOS devices into conventional plastic snow trays used for storage and transportation of other semiconductor devices. Ground the working surface of the service bench to protect the CMOS device. We recommend using a wrist strap, two ground cords, a table mat, and a floor mat. Wear a conductive wrist strap in series with a 100k resistor to ground. (Replacement wrist straps that connect to the bench top covering are Motorola part number 4280385A59). Do not wear nylon clothing while handling CMOS devices. Do not insert or remove CMOS devices with power applied. Check all power supplies used for testing CMOS devices to be certain that there are no voltage transients present. When straightening CMOS pins, provide ground straps for the apparatus used. When soldering, use a grounded soldering iron. If at all possible, handle CMOS devices by the package and not by the leads. Prior to touching the unit, touch an electrical ground to remove any static charge that you may have accumulated. The package and substrate may be electrically common. If so, the reaction of a discharge to the case would cause the same damage as touching the leads.

2.2

Repair Procedures and Techniques GeneralNOTE Environmentally Preferred Products (EPP) (refer to the marking on the printed circuit boards examples shown below) were developed and assembled using environmentally preferred components and solder assembly techniques to comply with the European Unions Restriction of Hazardous Substances (ROHS) Directive 2002/95/EC and Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC. To maintain product compliance and reliability, use only the Motorola specified parts in this manual.

Any rework or repair on Environmentally Preferred Products must be done using the appropriate lead-free solder wire and lead-free solder paste as stated in the following table: Table 2-1 Lead Free Solder Wire Part Number ListMotorola Part Number 1088929Y01 Alloy 95.5Sn/3.8Ag/0.7Cu Flux Type RMA Version Flux Content by Weight 2.7-3.2% Melting Point 217C Supplier Part number 52171 Diameter 0.015 Weight 1lb spool

Table 2-2 Lead Free Solder Paste Part Number ListMotorola Part Number 1085674C03 Manufacturer Part Number NC-SMQ230 Viscosity 900-1000KCPs Brookfield (5rpm) Type Type 3 (-325/+500) Composition & Percent Metal (95.5%Sn-3.8%Ag-0.7%Cu) 89.3% Liquid Temperature 217C

Parts Replacement and Substitution When damaged parts are replaced, identical parts should be used. If the identical replacement part is not locally available, check the parts list for the proper Motorola part number and order the part from the nearest Motorola Radio Products and Solutions Organization listed in Appendix A of this manual. Rigid Circuit Boards The repeater uses bonded, multi-layer, printed circuit boards. Since the inner layers are not accessible, some special considerations are required when soldering and unsoldering components. The printed through holes may interconnect multiple layers of the printed circuit. Therefore, exercise care to avoid pulling the plated circuit out of the hole. When soldering near a connector:

Avoid accidentally getting solder in the connector. Be careful not to form solder bridges between the connector pins. Examine your work closely for shorts due to solder bridges.

2-4


Chip Components Use the RLN4062 Hot-Air Repair Station for chip component replacement. Adjust the temperature control to 370 C (700 F), and adjust the airflow to a minimum setting. Airflow can vary due to component density.

To remove a chip component: 1. 2. 3. Use a hot-air hand piece and position the nozzle of the hand piece approximately 0.3 cm (1/8") above the component to be removed. Begin applying the hot air. Once the solder reflows, remove the component using a pair of tweezers. Using a solder wick and a soldering iron or a power desoldering station, remove the excess solder from the pads. Select the appropriate micro-tipped soldering iron and apply fresh solder to one of the solder pads. Using a pair of tweezers, position the new chip component in place while heating the fresh solder. Once solder wicks onto the new component, remove the heat from the solder. Heat the remaining pad with the soldering iron and apply solder until it wicks to the component. If necessary, touch up the first side. All solder joints should be smooth and shiny. Use the hot-air hand piece and reflow the solder on the solder pads to smooth it. Apply a drop of solder paste flux to each pad. Using a pair of tweezers, position the new component in place. Position the hot-air hand piece approximately 0.3 cm (1/8) above the component and begin applying heat. Once the solder wicks to the component, remove the heat and inspect the repair. All joints should be smooth and shiny.

To replace a chip component using a soldering iron: 1. 2. 3. 4.

To replace a chip component using hot air: 1. 2. 3. 4. 5.


2-5

Shields Removing and replacing shields is recommended to be done with an Air Blower, BOSCH GHG 600-3 or equivalent. The temperature should be set to approximately 400C (752F).

To remove the shield: 1. 2. 3. 4. 5. 6. Place the circuit board in the circuit board holder. Add solder paste flux around the base of the shield. Position the heat-focus head onto the shield. Turn on the heater and wait until the shield lifts off the circuit board. Once the shield is off, turn off the heat, and grab the part with a pair of tweezers. Remove the circuit board from the circuit board holder.

To replace the shield: 1. 2. Add solder to the shield if necessary, using a micro-tipped soldering iron. Next, rub the soldering iron tip along the edge of the shield to smooth out any excess solder. Use solder wick and a soldering iron to remove excess solder from the solder pads on the circuit board. Place the circuit board back in the circuit board holder. Place the shield on the circuit board using a pair of tweezers. Position the heat-focus head over the shield. Turn on the heater and wait for the solder to reflow. Once complete, turn off the heat, raise the heat-focus head and wait approximately one minute for the part to cool. Remove the circuit board and inspect the repair. No cleaning should be necessary.

Section 1 THEORY OF OPERATION1.0 OverviewThis section provides a detailed theory of operation for the Repeater Indicator Board and its components.

2.0

Repeater Indicator BoardThe Repeater Indicator board contains circuitry to drive the front panel indicator LEDs, an RTC battery for the RTC in the transmit radio, as well as an Ethernet controller for future development.

Front Panel Indicators

Display Driver

Ethernet to Rear Panel

USB to Ethernet Interface

RTC Backup

Flex to Transmit Radi oFigure 1-1 Repeater Indicator Board Block Diagram All of the indicator LEDs that are on the front of the Repeater chassis reside on the Repeater Indicator board. Each is controlled by a shift register (U6) data out signal and a digital transistor. The shift register accepts serial data in from the transmit radio's OMAP processor via a SPI bus. A 74LVC07 buffer (U9) level shifts these signals from 3.3 V to 1.8 V. The Repeater Disable LED is a dual-purpose LED that is hardware controlled initially at power-up. As soon as VBUS power is available on the Repeater Indicator board, the hardware circuitry for the Repeater Disable LED will cause it to blink periodically. When the software initialization is completed by the firmware, the blink circuitry will be disabled by the firmware. At that point, the Repeater Disable LED can be used for its intended purpose of displaying when the Repeater Disable function is turned on.

1-2

Repeater Indicator Board

The power LED is the only LED that is not controlled by the software. This bi-color LED gets turned on green when the 13.8 V output from the power supply is valid. It turns on red when A/C power is lost, and the repeater's backup battery is used. The Real Time Clock (RTC) battery (M1) is connected to the transmit radio through the Control Head Connector (J1, pin 30). Details of the Ethernet Controller will be provided when its functionality has been fully implemented.

Section 1 THEORY OF OPERATION1.0 OverviewThis section provides a detailed theory of operation for the Connector Board and its components.

2.0

Connector BoardThe Connector board has two purposes: provide a place for the Repeaters MAP and Ethernet connectors to be mounted and a location for the Repeaters fan control circuitry.

2.1

FanThe fan control logic is provided by the fan controller IC (U51). This is a device from Cypress Semiconductor. There are basically two functions provided by the fan controller. First, it provides a PWM output based on a temperature input, and secondly, it provides detection of fan failure based on the fan tachometer reading. The Repeaters internal chassis temperature is measured with an LM50 precision temperature sensor IC (U52). This IC outputs a voltage that is linearly proportional to temperature at 10 mV/C, and with an offset of +500 mV. The output voltage of the LM50 ranges from +200 mV at -30C to 1.1 V at +60C. The fan controller ID (U51) controls the speed of the fan by adjusting the PWM output (pin 1) from 0% to 100%. As long as the fan continues to work, pulses are output from the fan and input to the fan controller (pin 2). Should the fan controller detect that the fan has failed, it will generate a "Fan Fail" signal (pin 19) that signals to the transmit radio to cut back the transmit power.

2.2

AC/DC Power SupplyThe Repeater uses the PMPN4001A switch-mode, Power Supply Unit (PSU). It is capable of 200 W and designed for a 50 W UHF or VHF repeater system. This supply has UL, CE, and TUV regulatory approvals and is usable in all regions by using the correct line cord. The AC input is auto-ranging with no manual switch being specified to operate from 90 V-270 V and 47 Hz-63 Hz. It outputs a nominal voltage of 13.8 V with a voltage tolerance of +/- 5%. It has Power Factor Correction circuitry and is rated at 15 A across the whole operating temperature range of -30C to +60C. It also has a built-in battery revert circuit with a float output available for maintaining the charge on a battery and has UL, CE, & TUV approvals. The battery revert connector is accessible in the back of the power supply. The supply has over-load, over-voltage, and over-temperature protection. In an overload condition, the PSU goes into a hiccup mode where it recovers automatically after the fault condition is removed. During an over-voltage condition, the PSU shuts down and will have to be re-powered on to recover. In an over-temperature condition, the PSU also shuts down, but will recover after the temperature goes down. The PSU is not designed to be field serviceable. If it is determined that the PSU is not functioning, the whole unit needs to be replaced.

Voltage regulation is provided to the controller, GPS and RF sections by the following devices:

+9.3V_PA: U3005, U3006, and U3030 +9.3V_CNTRL: U3040 and U3030 +9.3V_SW: U3001 +12.6V_Ext SWB+: U3003 +1.5V GPS RTC: U6407 +1.4V OMAP Core: U3201 Supplies for the Controller section: U3200 (MAKO) Supplies for the RF and GPS sections: U0601, U0941,U3002,U3004,U6402, and U6406

The 9V3_PA regulator uses Op Amp U3030-1 as a controlling element. The regulated output voltage is divided by R3039 and R3040 and compared with an accurate reference voltage (5.1V DC) determined by VR3040. The Op Amp's output voltage at pin 1 varies the amount of conduction in transistors Q3032, U3005 and U3006 as necessary to keep voltages equal on pins 2 and 3 of the Op Amp. A characteristic of the Op Amp which allows the regulator to start up is the fact the output is high when both inputs are low, which occurs momentarily at turn-on. Dual diode D3030 serves two purposes. Diode D3030 is used to protect transistors U3005 and U3006 if the 9.3V_PA line is grounded. When this happens Q3032's base can only be 0.7V DC and transistors U3005 and U3006 will be turned off. Diode D3030 also provides temperature compensation of the regulated output voltage. The 9V3_PA supply powers the low level and driver stages of the RF power amplifier. The MAKO and GPS regulators are powered by the 9V3_CNTRL supply. Op amp U3030-2 functions as a controlling element for the 9V3_CNTRL regulator. The regulated output voltage is divided by R3045 and R3046 and compared with the reference voltage determined by VR3040. The Op Amp's output voltage at pin 7 varies the amount of conduction in transistors Q3040 and U3040 as necessary to keep equal voltages on pins 5 and 6 of the Op Amp. As is the case with the 9V3_PA regulator, the Op Amp characteristic allows the regulator to start up when both Op Amp inputs are momentarily low at turn-on. Dual diode D3040 serves two purposes. Diode D3040 is used to protect transistor U3040 if the 9.3V_CNTRL line is grounded. When this happens Q3040's base can only be 0.7V DC and transistor U3040 will be turned off. Diode D3030 also provides temperature compensation of the regulated output voltage. Regulator U3001 generates the 9.3 V required by most RF, power control, and audio circuits. Input and output capacitors C3005, and C3006/C3007/C3046 are used to reduce high frequency noise. R3003 and R3004 resistor divider set the output voltage to 9.3 V. This regulator output is electronically enabled by 0 V signal at pin 2. MAKO (U3200) FET_ENX, Q3206, and Q3041 are used to control the on-off at U3001 pin 2. Regulator U3003 generates the 12.6V required by external accessory device at connector J4000-7. Input and output capacitors C3012, and C3012 / C3013 are used to reduce high frequency noise. R3003 and R3004 resistor divider set the output voltage to 12.6V. This regulator output is electronically enabled by 0 V signal at pin 2. MAKO (U3200) FET_ENX, Q3206, and Q3041 are used to control the on-off at U3003 pin 2. There are a total of eight other LDO regulators used to regulate the 9.3 V supply down to specific application voltages. U0941, U3002, and U3004 are set to supply 5 V output. U0601 is set to supply 3 V for the Abacus III IC. U6402 and U6406 generate 2.8V for GPS Digital IO and RF circuitry while U6407 regulator provides 1.5 V for the GPS RTC module. U3201 regulator, which is capable of handling up to 1 Amp, is set to 1.4 V for the OMAP core.

Controller

Switcher1 (Q3200) in conjunction with the MAKO power management IC (U3200) is a highly efficient dc-dc converter. In this application, it is configured as a synchronous buck dc-dc regulator. It generates an accurate 3.6 V output, which supplies directly to the MAKO internal Switcher2 circuit as well as the 1.4 V regulator for the OMAP Core (U3201). A pulse width modulated (PWM) signal is output from U3200 pin G14 to Q3200 pin 4 and controls the output voltage level. External components L3200 and C3203 are needed to filter out the dc-dc converter output. R3200 (0.1 ohm) is used for current sense and over-current circuit protection with 2 A threshold. MAKO Switcher2 output 2.3 V and supplies to the rest of MAKO internal LDOs. Switcher5 (Q3202) circuitry is similar to Switcher1. It is also configured as a synchronous buck dc-dc regulator. It generates an accurate 5.2 V output, which supplies directly to both VBUS1 and VBUS2 supplies. External components L3202 and C3212 are needed to filter out the output. Q3208 and Q3207 prevent internal voltage leakage onto VBUS_SUPPLY (U3200 pin B13). When the radio is operated in the HOST mode, USB_CONNECT (U3200 pin L6) is toggled HIGH (3.3 V) turning on PMOS FET (Q3207) through Q3208 inverter, and thus provides 5.2 V to both Q3203 and Q3204 drains. Software will enable VBUS1_CMD and VBUS2_CMD either VBUS1 or VBUS2 port base on the detection mechanism. Note, only one of two VBUS ports can supply up to 500 mA (max) at one time. R3207 and R3208 (0.2 ohm) are used for current sense and over-current circuit protection with 800 mA threshold. In device mode, USB_CONNECT is toggled LOW to disable VBUS supply. The MAKO power management IC (U3200) provides eight more LDOs. Some LDOs are programmable to meet the requirement for various ASIC devices. V2, V3, and V9 are programmable via SPI while V4, V5, V6, V8, and V10 are fixed. See Figure 1-2 for details.

Power On/OffThe repeater is switched ON by use of the ignition sense input. This is internally wired on, in both transmit and receive radios. When the repeaters power supply is switched on, Q4006 is driven into saturation which pulls its collector to ground and presents an active low to MAKO IGN_X input (U3200 pin B4). When there is no voltage at J4000 pin 25, Q4006 is turned off and its collector is internally pulled high by the MAKO Vsave supply. Because of the noisy nature of ignition signal, a long debounce period of 250ms is used before it will be recognized as a valid input.

User switches on the power supply unit which initiates an ignition sense power on state. The MAKO (U3200) generates an output low at FET_ENX (pin E2) once it detects a valid input at either Mech_SW (pin E4), Emerg_PB (pin F4), or IGN_X (pin B4). Q3206 dual PNP/NPN transistor acts as a double inverter between the MAKO and Q3201 power MOSFET switch as well as over voltage protection. This logic low at the gate of Q3201 results in switching 9.3 V to both Q3200 Switcher circuitry and 1.4 V regulator (U3201). Next the MAKO (U3200) asserts the RESETX (pin C5) low to the OMAP for an additional 32mS after all the DC regulators are stable. It is then de-asserted, allowing the OMAP processor to start.

Figure 1-4 Clock Connections The OMAP processor (U1000), which consists of an ARM and DSP core, needs three clocks for operation: a 32.768 kHz square-wave, a 12 MHz sine-wave, and a 16.8 MHz square-wave clock. The 16.8 MHz clock source is provided from the Tomahawk TCXO with its supporting circuitry Q0100 buffer amplifier, routes to squarer-circuit U1006, and feed to EXT_CLK (U1000 pin N18). The 32.768 kHz clock is generated by the MAKO crystal Y3201 oscillator; converted to a gated clock by U3202 and U3303 circuitry; then directly feed to OMAP CLK32_
