1. MONITORING LAMP LIFE As normal arc lamp ages the voltage required to maintain the rated power goes up The power supply has the ability to sense this and make the necessary adjustments to the voltage and current When the voltage exceeds a pre determined threshold the lamp is no longer useful The power supply s multifunction display can display the time power volts and amperes at any given time From time to time switch between these display settings to get an idea how much life is left on your lamp When the voltage exceeds a pre determined threshold the lamp is no longer useful As anormal arc lamp ages and the electrodes erode the electrical characteristics change The voltage required to maintain the rated power goes up and the current goes down proportionately The power supply has the ability to sense this and make the necessary adjustments to the voltage and current As the voltage increases the current must decrease to maintain the proper power level The following table indicates the range of typical HBO 100 arc lamp operating param eters Lamp Voltage Current Characteristics HBO 100 Lamps bulb begins flashing 38 lamp nearing endo of life volts power supply shuts down 140 lamp no longer useful volts nominal current 5 0 new lamp amps current limit 2 50 replace lamp amps SPECIFICATIONS 1 115 3 amps NOTES LAMP REPLACEMENT HISTORY Elapsed Hours Initial2.

3. git LED display Shows the voltage time amps or power watts on the lamp The display function is controlled by the display selector switch The display will also show lamp ignition failure error and lamp aging status TIME RESET The recessed button switch will clear the lamp hours to zero This is used when a new lamp is installed LAMP POWER ADJUST This recessed control adjusts the lamp power from 10 to 20 of nominal lamp power For fine tuning lamp performance DISPLAY MODE SELECT Controls the display function The display can indicate time power amps or volts depending upon the position of this switch The switch position can be changed at any time MAIN POWER SWITCH Turns system on or off When switched on the power supply will display the lamp type setting for two seconds then attempt to ignite the lamp Switching off immediately extinguishes the lamp and shuts down power VOLTAGE SELECTOR SWITCH Located on the bottom panel of the power supply frame The slide switch is located in one of the vent slots toward the front of the unit Using a small scewdriver select between 115 and 220 volts Please note that different fuses are required for the different voltages INSTALLATION Verify that the voltage selector switch is set at the correct voltage and that proper fuses are installed The notation on the rear of the controller indicates proper fuse type Connect cord from lamp socket to connector on rear panel En
4. he display is updated continuously The power at any given time is equal to the product of the voltage and amperes VOLT Displays lamp voltage from 00 00 to 50 00 volts The voltage is shown to the nearest 0 01 volt The display is updated continu ously When the lamp ages the voltage will increase to a programmed limit for the 100 lamp AMPERE Displays lamp current from 00 00 to 10 00 amps The resolution 0 01 amp The display is updated continuously The current will decrease as the lamp ages to compensate for the increase in voltage INDICATION OF NEED FOR LAMP REPLACEMENT When display starts flashing bulb this indicates the lamp should be replaced soon because the power supply will not be able to control the wattage Before this occurs many users will change the lamp when a reduction in luminous flux occurs however when a reduction in light output occurs this may be compensated for by the WATT ADJUST control oun mur When the lamp is replaced reset the elapsed time indicator by pressing the recessed TIME RESET button WATT ADJUST This recessed control adjusts the lamp power from 10 to 20 of nominal lamp power A small 1 8 flat blade screwdriver adjusts the single turn control This control is best used to reduce wander a lamp or to extend the life of a lamp by operating at lower power To assist setting a slight deadband 2 of nominal lamp power is included
5. sure the lamp socket is properly installed in the lamp house Failure to do so may result in injury due to UV exposure or possible damage to the bulb Many lamp sockets incorporate a safety interlock which will prevent the power supply fromigniting the bulb unitl the socket is installed properly in the lamp house Turn on main power switch OPERATION The lamp type will be displayed for 2 seconds then the selected function switch will be displayed The display will indicate H100 for the HBO 100 lamp FAILURE LAMP TO IGNITE The lamp will usually turn on within 10 seconds If the lamp does not ignite within 30 seconds the power supply will shut down and Ign will be displayed Once the power supply shuts down the lamp will not start To reset this condition turn off the main switch for 10 seconds or more If the ignition failure continues it is usually an indication of a bad lamp open cable or socket DISPLAY FUNCTIONS TIME Lamp running time is displayed in hours and tenths HHH T with the decimal point flashing at a 1 second rate When power is shut off the elapsed time is stored On power up the previous value is restored and displayed and counting continues Lamp time is reset to zero when the TIME RESET button is pressed POWER Displays the power delivered to the lamp The display reads to the nearest 0 1 watt The power is calculated internally from the lamp current and voltage T
