General Information
Basic System Description
Model # 49501 is a medical light source which is used in conjunction with several Welch Allyn
medical instruments. This model has a built in Infrared filter to limit the heat generated by the
light. It also has an external ferrite bead built into the power cord to meet Electromagnetic
Interference (EMI) requirements, as required by medical standards.
Model HLS-24-0 is an industrial illuminator which can be used in many industrial applications.
The HLS-24-0 is also known at Welch Allyn as a 49501I (The I indicates that the unit is for
industrial use only). This instrument is identical to the 49501 medical light source with the
deletion of the Infrared filter and the Ferrite bead.

Words of Caution:
High Voltage
Use caution when servicing. When servicing the unit, potentially
dangerous high voltage levels are exposed. Disconnect the
power cord whenever possible to avoid electric shock.
Static Electricity (ESD)
Adhere to standard ESD practices at all times when servicing this
equipment. Many of the electronic devices in this equipment are
static sensitive, and may suffer catastrophic or latent failure if
handled improperly.
Heat
Lamps, power supplies, and heat sinks may emit extreme
amounts of heat during and after operation. Approach and
handle these and other potentially hot components with caution.
Finished Parts
Handle all finished parts with care. The finish can be easily scratched or
damaged from poor or improper handling.

Performance Checks
The following performance checks will help you (1) determine whether or not the system is
operating properly, and (2) isolates a problem, if there is one.
System Set Up
Make sure the system is connected as follows:
1. Be sure that power is being provided by the wall outlet.
2. Be sure that the Lamp is installed properly.
3. Be sure that the cooling fan is turning when the unit is turned on.
4. The light source should produce a bright continuous white light with no
flickering after it reaches the steady state (approx. 15-20 Sec).
If any of these conditions do not occur, see the troubleshooting section.

Maintenance
Preventative Maintenance
The purpose of preventative maintenance is to pro-actively reduce or eliminate future problems.
Keeping the Solarc Light Source in good operating condition ensures that it will perform reliably and
safely. Every six to twelve months, you should:
* Check power cable for wear.
* Ensure that, during use, the light source receives adequate ventilation.
* Ensure that the ball detent is still functioning properly.
Visual Inspection
Check for anything out of the ordinary. For instance:
- Does the light source make too much noise?
- Are there any loose parts inside the box?
- Is the power switch working properly?
- Do all components connect/disconnect easily?
- Are the ventilation holes free of obstructions?
CLEANING
Refer to Operating Manual, Welch Allyn Part Number 495003.
Light Source/Illuminator Service Manual Page 20
Section 5 Maintenance
Check Ground Continuity
1. Disconnect the power cord from the Solarc Light Source.
2. Verify the impedance between the ground pin of the IEC detachable gr ound cord and the thumb
screw meets the requirements as outlined on drawing A03387 in Appendix. A).
Measuring Leakage Current
To check the Chassis Leakage Current:
1. Connect the light source to a leakage tester (refer to figure 5-1), and measure leakage current
on leakage meter. Ensure that leakage is less than 100 microamperes.
2. Open ground line, and ensure leakage current is less than 100 microamperes.
3. Reverse line polarity, and ensure that leakage current is less than 100 microamperes.
4. With reversed polarity, open ground line and ensure leakage is less than 100 microamperes.
CAUTION: The meter must be suitably insulated and
capable of withstanding the power line voltage.
Light Source/Illuminator Service Manual Page 21
Section 5 Maintenance
LEAKAGE CURRENT TEST SET-UP
When the light source is used in conjunction with other accessories, it may be necessary to measure
the leakage current level of the entire set-up. A typical system setup is shown in Figure 5-1. Using a
standard leakage tester, this set-up will allow the overall sy stem leakage current to be measured. If this
value exceeds 100 microamps (or whatev er the maxi mum req uirements ar e for a particular region), an
isolation transformer should be used.

NOTE: Removing the cover will automatically cut off power to the Light Source.
4. Slide black connector off the lamp.
5. Remove the lamp assembly by pulling against the spring action and pulling up.
6. Acquire new replacement lamp assembly.
7. Reseat the new lamp assembly. Be sure that the pin on the lamp is properly seated into the
slot on the lamp bracket.
8. Slide black connector on to lamp.
9. Secure lamp cover.
10. Reconnect system to verify lamp operation and power interlock switch is closed.

Introduction
Theory of Operation
Model # 49501 is a
medical instruments. This model has a built in Infrared filter to limit the heat generated by the
light. It also has an external ferrite bead built into the power cord to meet Electromagnetic
Interference (EMI) requirements. This light source should only be used by qualified medical
personnel.
Model HLS-24-0 is an industrial illuminator which can be used in many industrial applications.
The HL S-24-0 is also known at Welch Allyn as a 49501I (The I indicates that the unit is for
industrial use only). This instrument is identical to the 49501 medical light source with the
deletion of the Infrared filter and the Ferrite bead.
Start up Routine (Lamp Ignition)
Upon turning the power switch to the "ON" position lamp ballast will ignite the lamps for an
approximate warm-up phase of 15 seconds. Once this warm-up phase is complete, the the lamps
will be warmed up, and the system will be ready for use.
Note: The fiber bundle must be in place to stabilize light output. Do not toggle the power switch
ON and OFF . Doing so will dramatically shorten lamp life. The lamp will not restart for 5-10
Seconds after power down.

Section 6 Theory of Operation
Power Supply
UNIVERSAL INPUT, SWITCHING AC TO DC MEDICAL GRADE POWE R SUPPLY
The power supply accepts an input voltage of 100-240 VAC, 50-60 Hz, single phase. The primary
circuit provides adequate control of leakage current, which is limited to 35 microamperes maximum.
The primary side of the power supply rectifies the AC vol tage and converts it to a high voltage DC lev el.
This DC vol tage is connected to the i solation transformer through a sw itching dev ice, typical ly a mosfet.
The mosfet is triggered by a high frequency clock circuit, typically at a 30-50 KHz rate. The
secondary side of this transformer provides isolation between primary and secondary circuits. The
secondary voltage i s rectified and filtered to pr ovide a + 15 VDC output vol tage at 5.3 amps. The output
voltage is regulated to 2%, with peak-to-peak noise of 150mV. The output is fully protected against
short circuit and output overload. Short circuit protection is a cycling type power limit with automatic
recovery after fault.
Ballast Board
The ballast board is a power supply used to operate the 24 watt Welch Allyn miniature arc lamp. The
nature of arc lamps require a ballast which limits the current, and therefore the power, in the lamp.
There are three states of the operation of the ballast: ignition, warm-up, and steady state. In ignition
the ballast provides the lamp with a train of ignition pulses between 6 and 7 kV. Once the lamp is
ignited the ballast conducts current at a very low impedance, which constitutes the warm-up phase.
Once it warms up, the impedance changes to a higher steady state value.
