VJ1000 6. Installation Procedure Introduction This chapter contains information necessary for the installation and initial testing of the VJ1000 amplifier. Is necessary, to not damage the amplfier, to execute the procedure below in the right www.DataSheet4U.com sequency. 6.2 Unpacking Remove the unit from its packing and, before any other operation, ensure that the unit has not suffered any damage in transit and that all its front panel controls are useable.

VJ1000 After having connected the 220 V driver supply and an RF output connector to the driver, switch the VJ1000’s POWER switch to OFF and the ST.BY. switch to ON. Adjust the exciter power output control to minimum power. Connect the line supply (220V ±5%) to the unit.
VJ1000 6.5 Fault Finding during the Setup Procedure The following fault conditions may occur during the setup procedure: THE RED LIGHT "PRESS." STAYS ON Check that the rear air filter is not blocked and that there is at least 40/50 cm clearance between the rear of the unit and any obstructions such as a wall.

VJ1000 7.4 Replacement of the Tube Ensure that the unit is isolated from its supply and, to avoidsevere burns, that the tube that has to be replaced is no longer hot. Ensure also that all terminals are at 0V, and if not use a shorting stick to remove any residual charge.
VJ1000 8. Calibration Procedure N.B. THE FOLLOWING PROCEDURE SHOULD ONLY BE CARRIED OUT BY QUALIFIED PERSONNEL USING THE CORRECT TOOLS AND EQUIPMENT. UNQUALIFIED OR INEXPERIENCED PERSONNEL NOT USING THE CORRECT TOOLS AND EQUIPMENT CAN EASILY CAUSE DAMAGE TO THE UNIT WHICH WILL IMMEDIATELY INVALIDATE THE GUARANTEE.
VJ1000 REPEAT STEPS 7 AND 8 SEVERAL TIMES TO OBTAIN THE OPTIMUM SETTINGS Increase exciter power until an output power of 800/850 W is obtained and repeat steps 7 and 8. 10) With output power at 1000 W, make small adjustments, as above, to minimize grid and anode currents;...
Perform the calibration procedure for the V.S.W.R. protection upto step b) (paragraph 5.2 (2)). At this point verify that the VJ1000 meter reading is correct; adjustment may be made with trimer R6 situated in the directional coupler on the output of the low-pass filter, near the antenna connector.
The polarity should be such as to produce a clockwise deflection. www.DataSheet4U.com Increase the power supply voltage and check for a proportional increase in the grid current (as measured by the VJ1000 meter) and in the current supplied by the power supply. Adjust trimmer R2 for a correct reading.

VJ1000 10. Telemetry Card Option 10.1 Calibration of the Voltages on the Telemetry connector The VJ’s internal Telemetry connector gives to the external the voltages referred to the various values under control. The voltage related to the Forward Power output is 1,6V for 1KW. To calibrate this voltage follow the procedure below: Adjust the power of the machine to the nominal value of 1KW.
When Standby mode and operating the ralated switch, the exciter shall go in RF Mute mode. VJ1000/2000 shall switch to Standby mode if the exciter put in the OFF status. www.DataSheet4U.com If the VJ has completed a reset cicle for 6 times and it’s thus blocked, a series of ON-OFF-ON of the exciter shall reset the alarms.
