PL900 ILLUMINATOR

A PRODUCT OF DOLAN-JENNER INDUSTRIES

Operation Manual

Setup

Voltage Selection:

Read and review the instructions on the label covering the power entry module and the instructions in

this section prior to connecting power to the illuminator.

Notice: The user must set the illuminator to the correct voltage prior to connecting the illuminator to
the AC power mains. Connecting the illuminator to the AC power mains without setting the voltage selector
switch to the correct value may result in damage to the illuminator and may void the warranty.

The PL900 illuminator can operate at either 115 VAC 50/60 Hz or 230 VAC 50/60 Hz. All PL900
illuminators are shipped with the voltage set for 230 VAC. To operate the PL900 at 115 VAC the user
must move the voltage selector switch to the 115 setting prior to connecting power to the illuminator.

Fiber Optic Connection

Notice: Do not operate the illuminator without the fiber optic connected to the illuminator.

Loosen the fiber optic nosepiece thumbscrew.

Insert the fiber optic into the illuminator nosepiece.

Tighten the thumbscrew by hand to make a secure connection to the fiber optic. Use of pliers or

other tools is not recommended.

Two nosepiece styles are available with the PL900 series of fiber optic illuminators. A-type with a

0.985 in. (25mm) ID, or B-type with a 0.590 in. (15mm) ID smaller than the 0.985 in. ID.

A-type nosepieces require the use of adapters to mate fiber optic light guides smaller than the 0.985 in. ID.
Adapters fit into the nosepiece and reduce the ID to accept the chosen fiber optic. The fiber optic and the
adapter are secured with the thumbscrew. The following A-type adapters (SX-5, SX-6 & SX-7) are made
with an idler which allows quick disconnect of the fiber optic.

B-Type nosepieces will accept self-supporting goosenecks (EEG2823C, EEG3922C, BG2820C, etc.) and
ringlight (A3739B) fiber optics without the need for an adapter. Fiber optics smaller than the 0.590 in.
(15mm) ID will require the use of B-type adapters (SX-5B, SX-6B & SX-7B).

Operation

Insert the power cord into the power entry module at the rear of the illuminator. Next, insert the power

cord into a 3 wire grounded AC power receptacle. Use only approved power cord supplied with the

illuminator.

Press the ON(1)/OFF(0) rocker switch on the front panel to ON(1). The illuminator will light and is ready
for service.

Lamp Intensity Control:

All the PL900 series illuminators are equipped with a front panel manual solid state intensity control

and an external interface (9-pin, D style connector) for remote intensity control via a 0-5 VDC signal on
the back panel.

Manual:

The illuminator intensity is controlled by the rotary control located on the front panel of the
illuminator. The 0 position (when control is turned fully counter-clockwise) corresponds to the lowest
illuminator intensity. The 100 position (when control is turned fully clockwise) corresponds to the highest
illuminator intensity.

NOTE: Continuous operation of the illuminator at the highest intensity level will yield rated lamp life.

Operating the illuminator at reduced intensity can result in significantly extended lamp life.

Remote Interface:

To enable the remote interface, move the LOCAL/REMOTE, located on the rear panel of unit, to the
REMOTE position. When the switch is in the REMOTE position the front panel intensity control is not
active. See Fig. 1 for the Pin Functions on the 9 Pin D-Sub connector
not connected, the illuminator will run at the maximum intensity setting until the Remote Intensity Control
Pin is connected.

Remote Intensity Control:

The Remote Intensity Control is located on Pin 3 of the Remote Interface. When the LOCAL/REMOTE switch
is in the REMOTE position the intensity is controlled by the signal applied to Pin 3. NOTE: The front panel

intensity control is deactivated in remote mode.

The input signal must be limited to a 0 to +5 volt DC signal. A negative voltage or a voltage in excess of 5 volts
will cause the lamp to run at maximum intensity potentially shortening lamp life. The PL900 Remote Intensity
control is highly linear. At 0 volts the lamp voltage is 0 volts. At +5 volts the lamp voltage is the maximum
voltage for the lamp specified at the time the order was placed. A 2.5 volt input signal will cause the lamp to
run at 50% of lamp voltage. Refer to Table A for intermediate values.

Pin 1 can be used to supply power to a remote potentiometer. Connect the potentiometer as shown in Figure 2.
The 500 ohm series resistor prevents shorting the power supply on Pin 1 if the potentiometer should fail as a
short circuit. In all cases the minimum resistance between Pin 1 and common ground (Pins 2 and 7) must be at
least 500 ohms to prevent damage to the Pin 1 power supply.

The user may also use a fixed voltage divider to control the illuminator at a non-varying intensity level. Refer
to Figure 3 and the resistance values in Table A for sample resistor values and the corresponding lamp intensity
levels. In all cases, the minimum total resistance value connected between Pin 1 and common ground (Pins 2
and 7) must be 500 ohms (RA + RB > 500 ohms.)

Remote On-Off:

The lamp power can be controlled via Pin 6, see Fig 4. By connecting
Pin 6 to a logic high (+5v) signal(Pin 1) the lamp power will be
interrupted for as long as Pin 6 is connected to logic high. When the
contacts connecting Pin 6 are opened, removing the +5v from Pin 6,the
illuminator will return to the intensity level set by the signal connected
to Pin 3 or to the intensity level set by the front panel control. The
response time of the illuminator going from On to Off and Off to On is
dependent on the thermal response of the lamp. The lag time of the lamp
may be several hundred milliseconds from the time the Remote On-Off
signal is applied to the time the lamp attains either the full On or full Off
state. The response time of the power supply is less than 100
milliseconds.
