I. HAZARDS/SAFETY
1.1 POWER SUPPLY
68806-M
ARC LAMP POWER SUPPLY
Connections to or from any electrical device must never be made while the power supply is switched
on.
The Oriel Model 68806 Power Supply has
an open circuit voltage of >100 volts when the start switch
is pressed, and could be dangerous if care
is not exercised when the power supply is switched on.
Please follow these precautions when operating the power supply:
• Make all input and output connections before turning the power supply on.
• Do not use the power supply without its cover.
Ensure that the output terminals are properly connected to the lamp housing or lamp socket before
turning
on the power supply.
Don't open the power supply or disconnect the output leads while the power supply is on.
• Follow the lamp or lamp house manufacturer's recommendations and precautions when handling and
using lamps.
Never touch the lamp's quartz envelope with uncovered fingers; definitely not when operating the
lamp or immediately after a shutdown. Also, follow this precaution during lamp installation to avoid
damage to the lamp.
Do not start the lamp with the output control set above the current rating for the lamp.
1.2 ARC LAMPS AND LAMP HOUSINGS
Make sure that the leads are properly connected to the arc lamp. INCORRECT CONNECT/ON WILL
DESTROY THE LAMP ELECTRODES, AND POSSIBLY CAUSE AN EXPLOSION.
XENON AND MERCURY XENON ARC LAMPS
Xenon and Mercury Xenon arc lamps only operate with the anode (positive end)
up.
When an ORIEL LAMP HOUSING is used with a Xenon lamp, you should connect the cable from the (+
connection) on the lamp housing to the + (red) connection on the rear of the power supply.

\
MERCURY ARC LAMPS
68806-M
ARC LAMP POWER SUPPLY
Mercury (Hg) lamps only operate with the anode (positive end) down. Unlike Xe and Hg(Xe) arc lamps,
which stabilize quickly to the preset current, Mercury lamps require some time to reach their stable
operating condition. Several minutes
is typical, but the exact time depends on the cooling of the lamp.
• Make sure that the lamp is adequately cooled. A lamp, not properly cooled, will warm
up and may
lead to
an explosion.
Do not over cool the lamp. Over cooling will prevent the lamp from warming up. The lamp will operate
in an unstable manner with a high light ripple, and possibly shortening its useful life.
USE AN APPROPRIATE ORIEL LAMP HOUSING WITH THE ARC LAMPS TO
MAINTAIN PROPER COOLING
'. During warm up, a Mercury lamp has a lower impedance than NORMAL OPERATION. The voltage
during a warm
up is lower than the final voltage and if the lamp is run at the rated power, the current
is higherthan rated current. The 68806 Power Supply controls the current rather than the lamp power.
Increasing the current during lamp warm up will speed
up the process.
Make sure to reduce the current as the lamp warms up or the lamp will run at higher than rated
power. THIS WILL CAUSE SHORTER LAMP LIFE OR EXPLOSION.
The lamp
is a source of constant current. To prevent overpowering of the lamp as it ages,
monitor its current on regular basis.

III. INTRODUCTION
111.1 DESCRIPTION
68806·M
ARC LAMP POWER SUPPLY
The Oriel model 68806 arc lamp power supply is a highly regulated source of current that maintains
constant light output necessary for proper operation of arc lamps. Constant current operation of these
sources of radiation
is required whenever a radiometric measurement is being made or whenever a highly
stable light output is needed.
The 68806 allows arc lamps to operate
in constant current mode, with the output voltage being dependent
on the lamp's impedance. The power supply will provide a constant current of up to
11 amperes with a
load voltage range of 0 to 100 volts. A power limit, which limits the product of output voltage and current
to 300 watts, protects the unit from output overloads. A constant current power supply regulates current
even into a short circuit. Lamp current
is limited to a maximum of 12 amperes. The reduced inrush
•.. current minimizes electrode erosion when starting the arc lamp. The Oriel model 68806 Arc Lamp Power
Supply includes all of the circuitry to start and power the lamps, and meter the output parameters.
.The following Oriel arc lamps may be operated with the model 68806 Arc Lamp Supply:

IV. CONTROLS AND CONNECTIONS
68806-M
ARC LAMP POWER SUPPLY
This section will describe the various controls, the available connections, and their function. Please
become familiar with their uses before operating the power supply with any lamps. This will reduce
the possibility of damaging the power supply or the lamps through improper operation.

The analog meter, (A in Figure 1), is scaled to display the output voltage, current, and wattage. Keep
in mind that the metermonitors the output voltage of the supply notthe load, and that the outputpower
is always displayed
by the meter. The one exception is when the preadjust switch is pressed and
operating current is displayed. The
select switch, (8 in Figure 1), enables you to momentarily view the
output
voltage or current by pressing it left or right, respectively.
OUTPUT AND CURRENT PREADJUST SWITCH
A ten turn
potentiometer, (C in Figure 1), is used to provide a precise means of output current
adjustment. A shaft lock
is mounted with this knob to lock in a setting if a readjustment from a previous
current setting
is not desired. When the preadjust switch (0, Figure 1) is pressed, the meter will display
the value of the output current that will be delivered
to the lamp after lamp start.
POWER SWITCH
This
is the AC mains power switch (E in Figure 1). In the "ON" position AC power will be switched into the
main circuitry of the power supply, and an integral indicator lamp will glow to indicate that the power
supply is on. The power switch
is also a circuit breaker which will open both of the AC lines to the internal
circuitry
in case of a fault within the unit.

This connection must be made, otherwise the main power supply will not turn on. ORIEL normally ships
a shorting plug which mates to this socket. The shorting plug must be replaced with the connector that
is supplied with the lamp housing in order to take advantage of its protection feature. Lamp housings
available through ORIEL use this connection as a safety arc lamp shut-off
in case the access doors are
opened when the lamp
is operating or in case of an excessive temperature rise within the lamp housing.
If you are not using an ORIEL lamp housing, for personal safety you should consider including
an interlock
circuit
in your equipment.
DC OUTPUT CONNECTIONS (J306 and J307, Figure 2)
These two UHF screw on connectors are the connections for the main DC output to the load. J306 is the
positive, and J307
is the negative. The low voltage side of an external ignitor or a lamp housing with built-
in ignitor is connected to these two outputs. Both are earth ground isolated. Never make any electrical
connections to these sockets with the power supply on.

V. OPERATING THE POWER SUPPLY
IV.1 SETUP AND USE
68806-M
ARC LAMP POWER SUPPLY
The Oriel Model 68806 Arc Lamp Power Supply was designed for use with a wide variety of arc lamp light sources.
Please follow the above precautions, and the following procedures to use the power supply safely.
OPEN CIRCUIT SETUP
Make all connections to the ignitor and to the housing. If
an interlock cable is available, then connect this to the
power supply interlock socket. Otherwise, use the jumper plug that was shipped with the power supply. The
, interlock operates by interrupting a 24
VAG source to an internal relay. Therefore, this must be a jumper or contact
closure and not a ground connection.
CAUTION
YOU MAY USE THE JUMPER PLUG
IF NO INTERLOCK CABLE EXISTS,
HOWEVER, THERE WILL
NOT BE ANY INTERLOCKOR TEMPERATURE
PROTECTION.
Install the arc lamp according to the directions in the housing manual. Pay strict attention to the electrical,
and the physical orientation of the lamp.
If the lamp operating current is unknown, then determine the current setting by using Ohm's Law:
amperes =power + volts.
Check that the line voltage selector is in the proper position for operation in your area. Connect the line
cord to the IEC socket, and plug the unit into an AC outlet.
Ensure that the "OUTPUT" control knob
is set to the full counterclockwise position. Turn on the power
supply. Place the meter select switch to
"VOLTS" and observe that the output is '" 100 volts DC. Release
the meter switch.
Press the "PREADJUST" switch. Read the meter display on the ampere scale. This is the operating
output current which will be delivered to the arc lamp. Turn the "OUTPUT" knob to set the desired
operating current. This step is necessary only when initially setting up the power supply or whenever a
new lamp with a different current rating is going to be used.
CAUTION
IF THE PREVIOUS STEPS ARE NOT FOLLOWED DAMAGE TO THE LAMP COULD
OCCUR BECAUSE
OF THE POSSIBLE HIGHER OPERATING CURRENTSETTING
OF THE "OUTPUT" CONTROL KNOB.

68806-M
ARC LAMP POWER SUPPLY
Press the "START" switch on the power supply front panel. The output voltage should measure off-scale
on the meter, and the ignitor should fire a high voltage pulse to begin the lamp start. Power will now be
delivered to the lamp, and the meter will display this value. To view the output voltage or current simply
place the momentary contact, and the meter select switch to the respective position, and monitor the
appropriate scale.
V.2 IGNITION
Arc lamps are filled with inert gas so the gap between electrodes
is normally non-conducting. Starting
a lamp means making this gap conduct; to do this we apply fast, high voltage (up to 35 kV) pulses
between the electrodes. These pulses cause ionization of the gas between the electrodes.
Short high voltage electrical pulses have other effects; you can get a shock or tingle if you are in contact
.;with the electrodes or power supply output. Such pulses find unusual ways of escaping from the path you
intend for them. They "leak" out of cables due to capacitive coupling and will "track to ground" across any
dirty surface.
Loss or weakening of the ignition pulses will cause difficulty in starting the lamp (see also the
Troubleshooting Section of this manual). If you are having such difficulty then:
Check that the connections are tight
Re-route power supply cable away from any conductive surfaces such as instrument housing or
optical table tops.

VI. CIRCUIT DESCRIPTION
VI.1 GENERAL
68806-M
ARC LAMP POWER SUPPLY
Please refer to schematic number 68806-3-1001 when reading this section. The schematic gives a block
diagram view of the major components of the
power supply. The 68806 was designed in a modular way
for reliability and for maintenance, and the schematic reflects this component approach to
the power
supply design.
The input mains is applied via J304, through the circuit breaker/powerswitch, and the line voltage selector
to T1.
T1 steps down the input to a low voltage AC (24 volts nominal) which is then connected to the coil
of K1. The AC connection is not complete unless the interlock is made by a
jumper or a contact closure.
A complete connection at J301 will energize
K1 and allow mains power to be applied to the main power
•... supply module (27-20-007). The power supply module will then begin to operate and convert the AC
mains voltage to a line isolated DC current.
The power supply module is a state-of-the-art, current
... mode, switching power supply which operates at 40kHz.
The meter board (68806-1210) continuously monitors the output of the power supply via J1. It also
provides the required voltage levels for the meter, and for the remote inputs and outputs
via J2 and J302.
DC power is then delivered to the load through the rear panel mounted connectors,
J306 (positive/+) and
J307 (negative/-). Either of these connections
may be ground referenced, if needed, because these are
line isolated outputs.

VII. CALIBRATION AND TROUBLESHOOTING
WARNING·
68806-M
ARC LAMP POWER SUPPLY
THE POWER MODULE (27-20-007) OF THE MODEL 68806 POWER SUPPLY HAS
NO FIELD SERVICEABLE PARTS. DO NOT ATTEMPT TO REPAIR THE MODULE
IN THE FIELD. IF A FAILURE OF THE MODULE OCCURS, THEN CONTACT YOUR
LOCAL REPRESENTATIVE FOR SERVICE.
ONLY QUALIFIED SERVICE PERSONNEL SHOULD ATTEMPTREPAIR OR
CALIBRATION OF THE POWER SUPPLY. THEY
MUST EXERCISE EXTREME
, CAUTION WHEN WORKING
IN THE UNIT WITH POWER ON. DANGEROUS
VOLTAGE LEVELS
EXIST WITHIN THE UNIT WHICH COULD HARM IF PROPER,
, ELECTRONIC TROUBLESHOOTING TECHNIQUES
ARE NOT ADHERED TO.
VII.1 CALIBRATION
The required equipment to calibrate the power the power supply, is an external 300 watt load resistor of
less than 30, and external voltage and current meters.
With the unit off, remove the top cover, and connect the ammeter in series with the load resistor. Connect
the voltmeter across the positive and negative output posts at the rear panel. Turn the "ADJUST" knob
full counterclockwise.
Switch the power supply on and adjust the output via the front panel control so that the output current, as
viewed on the external ammeter, is an even value. Hold the meter select switch in the "AMPS" position
and trim R6 so that the front panel meter display agrees with the external ammeter.
Without changing the control knob setting press the "PREADJUST" switch. Trim R16 so that the front
panel meter displays the output current setting. There will be a slight decrease in the output current when
this switch
is pressed. Adjust R16 to the output current value that was measured with the external
ammeter prior to pressing this switch.
Hold the meter select switch
in the "VOLTS" position and, rotate the front panel control knob so that the
output voltage is an even value. Trim R13 so that the front panel meter agrees with the external
voltmeter.
Release the meter select switch and adjust the output with the front panel control until the product
of the
external meters is an even value. Trim R12 so that the front panel meter agrees with this value.
Calibration is now complete. Switch the power supply off, and replace the cover.

VII.2 TROUBLESHOOTING
68806-M
ARC LAMP
POWER SUPPLY
The possibility of a fault occurring during its operational life is likely with any electronic equipment. We
have strived to make this the most reliable power supply available_ A competent service person should
perform any maintenance if a problem does occur. It is strongly recommended that field repair be limited
to the repair or replacement of all components which are readily available. No attemptshouldbe made
to repair the powersupplymodule to the component level_ Simply replace and return the defective module
to Oriel.
A flow chart of a suggested approach to troubleshooting is on the next page. Please use it as a guide for
resolving any problems. This is general in nature and should be used as a starting point. Do not forget
,the analysis of obvious problems such as; loose or broken wires, blown fuses or circuit breakers and
unconnected external cables.
VII.3 SPECIFIC DESCRIPTIONS
POWER MODULE
(27-20-007)
This module is not meant to be field serviceable, therefore only a general theory of operation is provided.
The module is easily replaced in the field,
and should be treated as a replaceable component. Please
contact
your representative if any problems arise.
This module is an off-line two transistor forward converter operating at a frequency of 40kHz. The
switching stage operates in current mode for increased reliability and for improved line voltage regulation.
The input stage
is connected directly to the AC mains, and line voltage selection is done by S301. This
is then rectified and filtered to provide the bulk, unregulated DC voltage for the switching stage. An on
board, low current transformer steps down, and line isolates the control circuit's power source. An
advanced secondary side filter network, and feedback loop serve to maintain a constant DC output current
with excellent regulation and control.
METER BOARD (68806-1210)
Please refer to schematic number 68806-3-1211 for this circuitry.
J1 pins 7 and 9 provide the AC for this circuit. This is rectified and filtered by CR1, C1 and C3. The raw
DC is applied to VR1 and VR2 which then supply the regulated +/- 15 volts for the supervisory circuits.
The output current signal enters the board via J1 pin 6 where it is then amplified by a two stage
operational amplifier (U1). The nominal voltage gain is 85. The output of the second stage is present at
one
of the inputs to U2, and is also scaled by R5 and R6 to provide the current for the meter.
The output voltage signal enters the board via J1 pin 10. A resistive voltage divider consisting of R8 and
R11 scale this to a 0-10 volt level which is then present at the other input to U2. Scaling for the meter
is done by the R9, R13 combination.
The power reading is derived by analog multiplier U2. This integrated circuit multiplies the proportional
input representation of output current and voltage at pins 1 and 3. The output from U2 at pin 7 is then
scaled for the meter to display power.

68806-M
ARC LAMP POWER SUPPLY
The reference voltage from the power module enters the meter board at J1 pin 1. It is then connected
to the front panel mounted adjustment potentiometer, R201, whose wiper is connected to J3 pin 2. This
variable voltage exits the meter board via
J1 pin 2, and is then reconnected to the power module. As the
wiper voltage changes from
0-5 volts, the output of the module changes.
J4 serves
as the interface to the meter, the meter select switch, and the preadjust switch. See schematic
number 68806-3-1001.
. J2 serves as the interface to the rear panel mounted remote socket
to provide the signal levels, or accept
the external signal level for remote monitoring and control of the power supply. The nomenclature for the
pins
is given in Section 111-5 .
.. The four, top mounted trimmer potentiometers are used only to calibrate the meter. They have no
... interaction with the power module. Their function is as follows:
R6 Current display trimmer
R12 Power display trimmer
R13 Voltage display trimmer
R16 Preadjust display trimmer
See schematic number 68806-3-1211 for their location.
IGNITOR DRIVE (68810-3-1601)
Please refer to schematic number 68810-3-1601 for this circuitry.
IGNITOR DRIVE AND OUTPUT MONITOR CIRCUIT
The ignitor drive PCB contains circuitry to generate the 25kHz square wave required by the ignitor. It
is
a self oScillating inverter which starts when relay K401 energizes at an open circuit voltage of 95 volts or
more. Relay contact K401-1
is closed and the start switch is pressed to apply 24 VAC to rectifier CR401.
The filtered output
is used by R402 to Slightly bias 0401 into conduction.
0401 goes into conduction more and more until T
401 saturates. At saturation, 0401's collector current
increases at the limit set by the beta of the transistor and input voltage. This limits collector current to one
ampere. Since dildt is removed from T401, 0401 shuts off due
to lack of base drive. The flyback voltage
is of the correct polarity to bias 0402 into conduction, and the action repeats but of opposite polarity. The
result will
be a two to one unregulated step up on T401's secondary. This is nominally a 100V P-P square
wave @ 30kHz. This square wave
is connected to the ignitor via J305 on the rear panel.
