10. The standard service life of the lamp housing is eight (8) years of use or 20,000 hours of total power ON period, whichever
is the shorter period.
For details, see Inspection Sheet on pages 18, 19.
IMPORTANT
This power supply unit is only for use with Olympus halogen lamp housings.
SAFETY PRECAUTIONS
1. A power supply is a precision instrument. Handle it with care and avoid subjecting it to sudden or severe impact.
2. Do not use the power supply where it is subjected to direct sunlight, high temperature and humidity, dust or vibrations.
3. For operation environmental conditions, see chapter 5, “SPECIFICATIONS” on page 8.
4. Always use the power cord provided by Olympus. If no power cord is provided, please select the proper power cord by
referring to the chapter “PROPER SELECTION OF THE POWER SUPPLY CORD” at the end of this instruction manual.
5. Always set the main switch on the power supply unit to “ ” (OFF) before connecting the power cord to the wall outlet.
6. This power supply is air-cooled so its surfaces become hot during operation. When installing it, leave spaces of more than
10cm around it. Also make sure to distribute cables away from the power supply.
7. To avoid potential shock hazard, make sure that the power cord is properly grounded.
8. Be sure to set the main switch to “ ” (OFF) and unplug the power cord before replacing the halogen lamp bulb.
9. The surfaces of the lamp housing will become extremely hot. When installing the lamp housing, be sure to allow ample free
spaces around and in particular above and below the lamp housing.

ASSEMBLY
1Connecting the Cables and Cords (Fig. 1 & 2)
The cables and cords are vulnerable when bent or twisted. Never
subject them to excessive force.
Make sure that the main switch is set to “ ” (OFF) before connecting
cables and power cord. Otherwise equipment failure may result.
1. Insert the hand switch plug @ into the connector ².
2. Insert the lamp housing plug ³ into the connector |.
Always use the power cord provided by Olympus. If no power cord is
provided with the microscope, please select the proper power cord
by referring to chapter “PROPER SELECTION OF THE POWER SUP-
PLY CORD” at the end of this instruction manual.
3. Insert the power cord plug ƒ into the connector ….
4. Insert the power cord plug † into the wall power outlet ‡.
The power cord should be connected to a grounded, 3-conductor
power outlet. If the power outlet is not grounded properly, Olympus
can no longer warrant the electrical safety performance of the equip-
ment.
If a cable or the power cord comes in contact with the lamp socket or
the surroundings, the cable or cord may melt down, causing electric
shock hazards. Be sure to distribute the cables at enough distance
from the lamp housing and power supply unit.

OPERATION
1Voltage Indication (Fig. 3 & 4)
1. Ensure that the brightness control knob @ is set to MIN (lowest voltage)
then set the main switch ² to “ I” (ON). (The POWER LED ³ lights up.)
2. Turn the control knob @ toward MAX (highest voltage) to increase the
voltage intensity and brighten the illumination.
}The position marked indicates the position with which daylight suitable
for photography can be obtained when an LBD filter is engaged in the
light path.
Hand Switch Operation
}When the hand switch is connected (the REMOTE LED | lights), the
brightness control knob @ is defeated but the brightness control knob ƒ
of the hand switch is activated.
1. Press the lamp ON-OFF switch … and adjust the brightness with the con-
trol knob ƒ.
2. To turn the lamp OFF, press the lamp ON-OFF switch … again.
# When the REMOTE LED | is lit, the hand switch in standby mode and
consumes about 2.5 W of power.
When the equipment is not to be used for a long period of time, be sure to
set the main switch ² to “ ” (OFF).

1Controlling the Amount of Light According to
External Analog Voltage (Fig. 5)
}The amount of light can be varied between MIN and MAX by applying a
DC voltage input from 0 to 5 V.
1. Connect a DC power supply as shown in Fig. 5. Do not turn on the power
supply yet.
2. Set the main switch to “ I” (ON).
3. Apply the external analog voltage.
DC voltages from 0 to 5 V correspond to the light amount from MIN to
MAX.
# The external wiring should have a wire gauge of AWG28 (0.1 mm2) or
more.
# Do not apply voltage above 5 V DC. Doing so will cause the unit to
malfunction.
#Do not apply the analog voltage before setting the main switch to
“ I” (ON). Doing so will cause the unit to malfunction.

2Remote ON/OFF Operation (Fig. 6)
}The lamp can be turned off by shorting pins 4 and 2 of the DIN 8-pin
connector.
#The external wiring should have a wire gauge of AWG28 (0.1 mm2) or
more.
#The external contact should be fully capable of switching 10 mA on
and off.
#When the lamp is to be turned on/off with the open collector, connect
the emitter to pin 2.

3Controlling the Amount of Light with External VR (Fig. 7)
Inside the power
supply unit }The amount of light can be controlled between MIN and MAX by connect-
ing an external VR.
1. Connect a VR as shown in Fig. 7.
2. Set the main switch to “ I” (ON).
3. The amount of light is minimized when the voltage at pin 1 is 0 V and
maximized when it is +5 V.
#The external wiring should have a wire gauge of AWG28 (0.1 mm2) or
more.
#Use an external VR of 10 0.1 W.

When lamp fails: Open collector output is “OFF” (i.e. there is
an open circuit between pins 4 and 7).
# The external wiring should have a wire gauge of AWG28 (0.1 mm2) or
more.
#External voltage connected to pin 4 should be negative and that
connected to pin 7 should be positive.
