magnetic sensor (CON 1)
Via the
con1
connector, you are able to test all the magnetic sensors of your projector as well as associated cabling and connec-
tors. In fact, you will be able to isolate defective magnetic sensors by connecting them to
con1
of your
sensor test PCB
and by
using the magnet provided simply moving it towards and away from the sensor. If the display of the
DR1
alternates between
ON
and
OFF
the sensor is functioning correctly, otherwise it will require replacement.
In a similar manner, you may also check for proper connection of the connectors and the integrity of the cabling by disconnecting the
sensor’s cable by its flanks at the motherboard and connecting one end to the
con1
connector of the
sensor test PCB
and the
other to the magnetic sensor provided with the kit. As before, moving the magnet forward and back will cause the display of the
DR1
to alternate
ON
and
OFF
if the cabling is undamaged. If not, the fault may lie with the cable or the connector.
1.
Attach the
CON1
connector to the magnetic sensor of your projector.
2.
Position the magnet in proximity to the sensor.
3.
Press the
remote
button on the display of the
DR1
; the display will show
D.REM
4.
By using the
+
or
-
buttons, scroll to the
SENS
option.
5.
Press the
enter
button; via the
+
or
-
scroll to
CON1
6.
Press the
enter
again and the display will show
OFF
. Move the magnet along the length and the display will show
ON
to indicate that the connector and cabling is operating correctly and that the magnet and sensor are correctly positioned with cor-
rect polarity.
7.
Repeat the procedure with all the magnetic sensors that need testing.
light sensor (CON 2)
Via the
con2
connector you may test the correct operation of the light sensor within the projector as well as of its connectors and
cabling. Locate the light sensor within the fixture and attach it to the
con2
connector of the
sensor test PCB
. Turn on the lamp
and the display of the
DR1
should read
ON
. If this is not the case, the sensor will require replacement. Additionally, you may also
test the connector and cabling by isolating the cable which connects the sensor to the motherboard and connecting one end to
the light sensor provided in the kit and the other end to the
con2
connector of the
sensor test PCB
. By moving the light sensor
close to and away from a light source, the display of the
DR1
. will alternate
ON
and
OFF
. Should this not be the case, the cabling
is damaged and will require replacement.
1.
Attach the
CON2
connector to the light sensor of your projector.
