Page 16: Contacting Lambda Americas Customer Service
The supply and the FC-72 filled HV assembly should not be opened unless advised by Lambda Americas personnel. The FC-72 filled HV tank has been cleaned and the her- metically sealed at the factory, opening the supply or the assembly will void the factory warranty, and may compromise performance. -

INSTALLATION 4-11 INSTALLATION 19-INCH RACK MOUNTING This power supply is intended for mounting in a conventional 19-inch rack. It’s 12.25 inch height makes it a “7U” size instrument. The rack should enclose the sides, top and back to protect the operator from electrical shock and protect the supply from environ- mental contamination. -

550VAC. If this voltage is exceeded, catastrophic damage will result, that is not covered by Lambda Americas standard warranty. The customer’s AC power line connects to the 203/303 via a UL/CSA approved 5 posi- tion terminal block on the rear panel of the unit (see Figure 4-3). Only use a power cable with the correct voltage and current rating (see Table 4-1). -
Page 20: Connecting The High Voltage Output
Always use the HV connector and cable provided with the power supply or an equivalent substitute provided by Lambda Americas. Fully insert the connector end of the HV cable and tighten the locking nut only "hand tight". When operating above 20kV and 200Hz rep rate a silicone grease (such as Dow Corn- ing DC-4) must be applied to the HV cable before insertion into the HV connector. -

5.2.3 COOLANT status LEDs In the event of any coolant faults the user should verify installation orientation is in ac- cordance with section 3.4 prior to contacting Lambda Americas. 5.2.3.1 FULL (Normally ON) When illuminated, this indicator signals that the high voltage tank in filled to the correct level with coolant. -
Page 27: Temp (Normally Off)
CONTROLS, INDICATORS, CONNECTORS 5.2.3.4 TEMP (Normally OFF) The TEMP LED Illuminates if the HV tank temperature is outside of its operating limits. The fixed operating limits have minimum low temperature and a maximum high tem- perature. When illuminated, the TEMP indicator will turn OFF the high voltage output. When the internal temperature returns to a normal level, the output may be switched back on by depressing the HV ON push-button. -
Page 28: Low (Normally Off)
CONTROLS, INDICATORS, CONNECTORS 5.2.4.4 LOW (Normally OFF) The LOW AC line LED will illuminate if the AC input voltage drops below approximately 85% of the nominal nameplate level. The power supply will continue to deliver output current unless voltage dip is too great (either low voltage or for a long time). The power supply will shut down the output until the AC line is restored. -
Page 29: Local Voltage Control (Ref 2)
CONTROLS, INDICATORS, CONNECTORS LOCAL VOLTAGE CONTROL (Ref 2) The local voltage control potentiometer is a precision 10 turn dial indicator that adjusts the output voltage between zero and 100% of rated voltage. The output voltage can be set at the desired level by turning the dial to the required percentage before depressing the HV ON push button. -

NOTE: The 203/303 series power supplies are not designed to operate into an open cir- cuit load. Operating the supply with no external load capacitor could result in damage to the high voltage output section and would void the warranty. -
Page 38: Remote Operation (All Models)
OPERATING INSTRUCTIONS 6-16 To turn OFF the power supply depress the OFF button or use the inhibit line. Opening the interlock terminals will also cause the power supply to turn off. In this case the unit can only be turned back on after the interlock has been closed and the ON button de- pressed followed by the OFF button to RESET the fault. -
Page 39: Remote Control Signals
6.2.2 Remote Operation with AUTODWELL The simplest remote control for the 203/303 series power supplies requireds only an ex- ternal HV ON/OFF signal (Pin 10), and a Vprogram signal (Pin11), and ground (Pin 21/23). The Vprogram signal should be set to the appropriate analog level that corre- sponds to the desired output voltage. - Page 40 OPERATING INSTRUCTIONS 6-18 INTERLOCK INTERLOCK OPEN OPEN READY READY READY INPUT POWER FAULT INPUT POWER FAULT INHIBIT INHIBIT AUTO DWELL AUTO DWELL END OF CHARGE END OF CHARGE OVERLOAD OVERLOAD EXCESS REV ERSAL EXCESS REV ERSAL COOLANT WARNING COOLANT WARNING COOLANT FAILURE (LOW COOLANT OR TEMP FAULT) COOLANT FAILURE (LOW COOLANT OR TEMP FAULT) OVER VOLTAGE...
