1.
Check the
voltages
on
the co
ntrol
board
test
points
TP22 and TP23.
•
If
the
test
points
read
12V
and
0V
respectively
,
then the ballast
is faulty
. Replace the ba
llast.
•
If
the
voltages
are
in
the
vicinity
of
5.5V
and
7V respectively, proceed to step 2.
2.
Visually
check
if
the
bulb
door
is
properly
closed with the cover or a stand-alone magnet. If
necessary, close the
door.
3.
Visually
check
if
the ligh
t
cable
is
properly
inserted
into the jaw. If necessary, reinsert the
cable.
4.
Visually
check
if
the b
ulb
has the
one-wire
memory
chip. If it does, ensure the chip makes contact with
the bulb mount board connector. If necessar
y,
adjust contact between the chip and the
connector
.
5.
Using
a
multimeter
,
electronically
check
the
following test points on the control board. Each
test
point should read 3.3
volts.
•
PD1—reads
3.3
volts
if
the
one
wire
chip
is
detected by the control board. If PD1 reads 0
volts (and PD2
reads 3.3 volts),
try a di
ff
erent
bulb. Push the bulb
fi
rmly towards the plastic
separator panel to ensure contact.
•
PD2—reads
3.3
volts
if
the
door
reed
switches
are closed. If PD2 reads 0
volts,
-
Check
if
the
reed
switches
on
the
bulb
mount boards are s
oldered properly
. If
necessary, repair the soldering.
-
Check
for
shorts
using
the
magnet
on
the
reed switch. Repair/replace as nec
essary.
-
Check
if
the
cable
wire
colors
are
correctly oriented. Adjust as necessar
y
.
•
PD3—reads
3.3
volts
if
the
fans
are
functioning
properly
•
PD4—reads
3.3
volts
if
a
regular
light
cable
is
inserted. If PD4 reads 0
volts, remove the front
panel and check if the beam sensor is properly
positioned and connected to the display board.
Adjust as necessar
y.
•
PD5—reads
3.3
volts
if
an
ESST
light
cable
is
inserted. If PD5 reads 0
volts, remove the front
panel and check if the beam sensor is properly
positioned and connected to the display board.
Adjust as necessar
y.

If the bulb turns on immediately a

er AC power is applied
to the light source, proceed to diagnosis strategy
C, “Bulb
ignites immediately upon system startup.”
If the bulb ignites a

er the regular startup sequence but then
will not turn o
ff
, perform the following steps until the source
of the problem is identi
fi
ed.
1.
Remove
the
light
cable
from
the
jaw.
2.
Open the
bulb
door
or
remove
the m
agnet
from
the
reed switches.
3.
Using
a
multimeter,
check the
following
test
points
on the control board:
•
PD2—If
PD2
reads
3.3
volts,
the
reed
switches
are faulty
. Replace the
reed switches.
•
PD4
and
PD5—If
either
PD4
or
PD5
reads
3.3
volts, the light
cable sensor (beam sensor) is
faulty
. Replace
the light
cable sensor.
4.
If
PD4 o
r PD5
reads 0
volts,
measure the
voltage
di
ff
erence between TP22 and TP23.
•
If
the
voltage
di
ff
erence is around -1.3 volts,
replace the ballast.
•
If
the
voltage
di
ff
erence is around 12 volts,
proceed to step 5.
5.
Measure
the
voltage
level
for
TP32.
•
If
TP32
reads
0
volts,
replace
the
control
board.
(See the Repair/Replacement Procedures
section of this manual.)
•
If
TP32
reads
3.3
volts,
proceed
to
step
6.
