2.0 SERVICE PROCEDURES
This section describes the procedures for Power Line Voltage
Settings and Fuse Replacement for Patton Models 1090, 1092, 1093,
1095, 1185, 2500, 2510, 2520 and 2703. Note: These procedures
apply generally to all products listed above, which (products) will
henceforth be referred to as “the unit”.
2.1 PROCEDURE FOR POWER LINE VOLTAGE SETTING
A. Switch the unit OFF.
B. Remove the power plug from the AC wall outlet.
C. Remove the power plug out of the rear of the unit.
D. Switch the unit ON and verify that none of the front panel status
indicators are lit. Switch the unit OFF.
E. Remove the metal screws located on the rear panel bottom left
and bottom right. DO NOT DISCARD THE SCREWS. Gently
slide the PC board and the rear panel out from the metal
enclosure.
F. Remove the nylon screws that hold the clear plastic shield
in place. Lift off the plastic shield. DO NOT DISCARD THE
SCREWS OR THE PLASTIC SHIELD.
G. With a flat blade screw driver, gently select the voltage to the
desired setting.
H. Look at the fuse rating shown on the label near the fuse holder.
The required rating is different for the new voltage setting you have
just selected, change the fuse. (See Section 2.2, Step G.)
I. Reinstall the plastic shield so that all of the holes line up with
the stand-offs. Reinstall the nylon screws. DO NOT
OVERTIGHTEN THE NYLON SCREWS!
J. Line up the PC board with the 2 slots located on the rear panel
bottom left and right. Gently slide the PC board/Rear panel
WARNING! When you change the voltage setting, you
may have to remove the fuse and replace it with a fuse of a
different value. (The proper fuse rating is marked on the
board near the fuse holder.) Operating this equipment
with the wrong fuse rating may result in a fire.
(Step G is for Models 1090, 1092, 1093, 1095, 1185, 2500, 2510 and
2520.)
G.) With a flat blade screw driver, gently pry off the fuse cover. DO
NOT DISCARD THIS COVER! Pull out the fuse. Replace the fuse
and reinstall the fuse cover.
(Steps H and I are for Model 2703.)
H.) With a flat blade screw driver, gently turn the movable section of
the fuse cartridge holder counterclockwise. The spring action
should push out the fuse.
I.) After inserting the correct fuse in the fuse cartridge holder, re-
insert the movable section of the fuse cartridge holder with the new
fuse into the fixed section of the fuse holder. Gently push and
rotate clockwise while pushing until some resistance is felt and the
cover is aligned with the fuse holder.
(Steps J to O apply to all units.)
J.) BEFORE CONNECTING THE POWER CORD, VERIFY THAT
THE LINE VOLTAGE IS WITHIN THE VOLTAGE RANGE
SPECIFIED FOR THE UNIT. THIS RATING IS STATED ON THE
LABEL ON THE BOTTOM OF THE UNIT. AN IMPROPER LINE
VOLTAGE CONNECTION MAY RESULT IN DAMAGE,
IMPROPER FUNCTIONING, OR BOTH. INSTALL THE CIRCUIT
POWER CORD ACCORDING TO THE OPERATORS'
MANUAL INSTRUCTIONS.
K.) Reinstall the plastic shield so that all of the holes line up with
the stand-offs. Reinstall the nylon screws. DO NOT
OVERTIGHTEN THE NYLON SCREWS!

WARNING! Replace the fuse only with one that has
the correct voltage and current rating for the voltage
setting of the unit (the proper fuse ratings is marked on
the board near the fuse holder). Replacing the fuse with
one having an incorrect rating can result in a fire!
