Your can read the load rms voltage on the displayMONITOR Use the following procedure to determine the proper tap number and establish the setpoint YOU Never change the tap number while the output power is enabled Changing tap settings while applying output power damages the power supply 1 Turn the POWER switch OFF and set the LEVEL knob fully counterclockwise 2 Select TAP NUMBER 1 3 Turn the circuit breaker and the POWER switch to ON PART At this time the display MONITOR and the LOCAL and INTERLOCK status indicators should light If the REMOTE indicator lights instead of the LOCAL indicator see the Troubleshooting section on page 5 7 If the INTERLOCK status indicator fails to light check to confirm that the interlock string is satisfied 4 Move the OUTPUT ON OFF rocker switch momentarily to ON You should hear contactor close and the OUTPUT status indicator should light 5 Move the LEVEL knob clockwise until the MONITOR reads approximately 10 of full output 170 W The PLASMA and SETPOINT status indicators should light 6 To check the output voltage or current move the DISPLAY rocker switch to either VOLTAGE or CURRENT setting 7 Make sure the SETPOINT status indicator is Gradually advance the LEVEL control knob to the desired power level If the SETPOINT indicator light flashes before you reach the desired power level turn off the supply and increase the TAP NUMBER by
11. one setting Slowly increase the power until you reach the desired power level or the SETPOINT indicator light flashes Repeat this process until you reach operating power without the SETPOINT light flashing NOTE the SETPOINT indicator light flashes in tap 1 and when you change to tap 2 the light continues flashing and the power level drops the load Impedance is too low to deliver power to the load Contact AE Customer Service for assistance If you reach tap 7 and you cannot obtain the operating power level before the SETPOINT indicator light flashes check the output voltage If the output voltage is greater than 1200 V the load impedance is too high for the power supply to deliver power to the required load Contact AE Customer Service PREPARING FOR USE 8 Increase the power 10 over the desired power level If the SETPOINT light does not flash you have the correct TAP NUMBER If the SETPOINT light does flash increase the TAP NUMBER by one 9 When you reach the desired power level lock the LEVEL control knob by turning the locking skirt clockwise The supply can be turned off and on and the power will return to setpoint automatically CONTENTS Remote Control Units built prior to 2 6 89 Units built after 2 6 89 4 1 ME ORL en units built prior to 2 6 89 1 Before removing the plastic safety shield turn off the supply and let it sit for 5 min before beginning
