120 20190-001 Paragon-III Technical Manual82.5 ElectricalStandard 120 VAC electrical power is required. It should be capable of providing at least 10A to powerParagon-III (<6A) and ancillary equipment.2.5.1 Paragon-III Assembly PowerTwo distinct power configurations (rear views) are shown in the preceding pages. They are:• Paragon-III Base Station Standard Assy.This configuration is described in paragraph 2.5.1.1 below.• Paragon-III Base Station Assy. with 3rd party DC supply (Figure 4).Refer to Dataradio System Engineering for further details.2.5.1.1 Standard Power Supply ConfigurationThe Radio assembly unit receives two separate 13.8 VDC power inputs from a “T800 Slimline” dualpower supply typically rack-mounted right below the main assembly radio chassis.The T800 is made up of two separate power supply units joined in a single chassis:• A T807 using convection cooling is rated to 15A nominal at 13.8VDC. It supplies all the radiomodules other than the Power Amplifier.• A T808 using convection and fan cooling is rated to 25A nominal at 13.8VDC. It supplies onlythe Power Amplifier module (T859, or T889).Normally used at room ambient temperatures, they can operate within their specifications over arange of –10 to +60 °C.Note: Internal over-temperature protection shuts down the main transformer above 105 degrees Cel-sius.Both power supply modules are internally connected to ground via their individual, rear-connected,seven-foot standard 120 VAC power cords. Nevertheless, each requires a separate secure electricalground connection. Individual grounding tabs are provided next to the power connectors.Similarly, the Radio Assembly chassis requires a secure ground connection. A threaded groundingbinding post fitted with a knurled binding-nut is provided on the chassis next to DC input 2. Separategrounding leads with appropriate connectors are supplied (either in the courtesy small-parts kit orwith one end fastened to the equipment.• For each of the power supply modules, fit one end of the grounding lead’s push-on connectoronto the grounding tab.• For the Radio Assembly chassis, install the grounding lead’s lug over the binding post and firmlyhand-tighten the binding-nut.• For both T807 and T808 power supply modules1. Fit the slotted connector (on the other end of each of the grounding connector) under aconveniently located screw on the rack frame or other support surface. Scrape away paintif needed to ensure clean contact.2. Apply anti-corrosion compound where paint scraping was done.3. Ensure by testing continuity that a secure electrical and mechanical connection isachieved.If a –DC rail (0V) is installed as part of the system, the grounding leads may alternatively be fit-ted to the rail terminal.Caution:Improper grounding between power supply case and rack frame may result in harmful voltage po-tentials and/or miscellaneous power supply switching noise problems in both receivers and trans-mitter.
120 20190-001 Paragon-III Technical Manual92.5.1.1.1 T808/807 DC Power Supply Connection & Torque SettingsWarning: Securing the DC Power Supply cable into the DC connector to provide a good electricalconnection is essential. Over time, the wires tend to compress in the DC connector re-sulting in an increasingly poorer connection. Consequently, as high current is drawn,the connector heats up increasing the resistance thereby causing still more heat until theconnector eventually burns up.Although screws securing DC cables to the Power Supply terminals are tightened to the torque set-tings given below prior to new system delivery, they must be re-tightened as part of the commis-sioning process and re-tightening is also part of the regular maintenance schedule.Prior to replacing a Power Supply module into an existing system, inspect the cable and re-terminatethe DC wires if the strands have previously been twisted together or show any sign of damage.Cut the wire at the end of the insulation and then strip approximately .4 inch (10mm) of insula-tion off the cable. DO NOT TWIST THE WIRE STRANDS. Insert the DC cable into the screwterminal and tighten the screw to secure the cable as per the torque settings given below.Torque Settings:The manufacturer recommends torque setting all power supply terminal screws to:• 0.5 to 0.6 Nm (or 4.5 to 5.3 In/lb or to .37 to .44 ft/lb)Note: Dataradio uses a Sturtuvan Richmond 29-pieces adjustable torque screwdriver modelCAL36/4K.After tightening, pull on the cable to check the cable is secured tightly into the screw terminal.2.5.1.1.2 Power Indications• Press both red power buttons located on the front of the module to have complete power distri-bution to the Radio assembly. The power supply front panel LEDs indications are:Table 2 - Power Supply, LEDs indicationsLED Color IndicationOn Green Power enabled *Stby Red Power disabled *OL Steady Red Current OverloadOn & OL Flashing green and red respectively Over voltage* To remove voltage from the power supply PCB, disconnect the main power cords.• For other Paragon-III LEDs descriptions, see section Error!

120 20190-001 Paragon-III Technical Manual102.6 Antenna2.6.1 OverviewParagon-III commonly uses three antennas (one transmit and two receive) unless a duplexer is usedwith one of the receive antennas; then only two antennas would be needed. They should be mountedaccording to any guidelines supplied with the antennas. For antennas placement and spacing, consultSystem Engineering.2.6.2 Cabling and Connection1- Route good quality 50-ohm double-shielded coaxial cable(s) (e.g. RG-214 or Heliax) from theselected antenna position(s) to the Paragon-III Radio assembly.2- Terminate the RX-1 and RX-2 cable-ends at the Receiver modules rear position with an N-typeconnector.3- Similarly, terminate the TX cable-end at the Power Amp’s module rear position with an N-typeconnector.Caution:When terminating RF cables use brand-name crimping tools (such as AMP, Jensen,Crimp-Master, etc…) of the correct size for the cable and type of connector used.Common pliers are NOT acceptable.2.7 Completing the physical Installation.Paragon-III products are factory-configured to user’s requirements and are shipped ready to run.After new installations:• Re-check that all connections are secure on the radio-BDLC assemblies (antennas, PC, powercords etc.)• Check that fuses are inserted.• Turn both BDLC-III and radio power ON.You are now ready to check for normal operation (as per paragraph 2.8) and to run the DataradioCDip program for testing or trouble-shooting.Any change(s) to the settings must be done via files saved on diskette and loaded into the unit usingthe CDip program.2.8 Checking out Normal Operation1- Check that power is applied.2- Check Radio assembly lights for proper operation as per section 3.1.13- Check for proper operation of the BDLC-III’s LEDs.4- Using the CDip program and an in-line wattmeter, check forward & reverse power to confirmmain antenna installation5- Using CDip, check the RF Data Link with a mobile that can be heard (as per section 4.3.1)If user application and mobiles are available, test the installation by going through a normal sequenceof transmitting and receiving messages.

120 20190-001 Paragon-III Technical Manual335.2.4.4 Tait T859 (UHF) Standard Tuning Procedure1. For sets with serial numbers following 217262, set RV69 (driver power level) fully clockwise.2. For all units, preset the tuning controls as shown in Figure 19Figure 19 - T859 Tuning settings3. Set RV63 (front panel power control) fully clockwise.4. Key on the exciter (press PTT button).5. Adjust CV1 for maximum output.6. Adjust CV8 for maximum output.7. Adjust CV32 for maximum output.8. Adjust CV51 and CV57 for maximum output.9. Adjust CV34 and CV35 for maximum output.10. Recheck all settings. The power output should exceed 110W.11. For sets with serial numbers following 217262, adjust RV69 (driver power level) untilthe output power drops to 110W.12. For all units, adjust RV63 (front panel power control) to reduce the power output to the requiredlevel (normally 100W).5.2.4.5 Tait T859 Tuning for Best Efficiency1. Insert a Shunt current device (HP 34330A Shunt 30A ) between the power supply red wire andits 13.8Vdc output, then connect the shunt to the multimeter (VDC scale)2. While transmitting, monitor the current. It should remain under 22A.3. Retune CV32, CV51 and CV57 towards maximum capacitance to obtain minimum supply cur-rent, but do not exceed a maximum drop of 0.5A per control.4. Check that the supply current is <22A for 100W output power.Note: These control settings are normally very close to minimum supply current. If the current is re-duced too far, maximum power output will drop and 2f rejection may degrade.
