5.0 SERVICE PROCEDURES
This section describes the procedures for Power Line Voltage
Settings and Fuse Replacement for Patton Models 1000RPSM-2,
1000RPEM, 1000RPSM-V and 1000RPEM-V. Note: These procedures apply
generally to all products listed above, which (products) will henceforth
be referred to as “the unit”.
5.1 PROCEDURE FOR POWER LINE VOLTAGE SETTING:
MODELS 1000RPSM-2 AND 1000RPSM-V
Although the Models 1000RPSM-2 and 1000RPSM-V are shipped
from the factory with a customer-specified power supply configuration,
you may change the configuration yourself. Here are the steps to switch
the configuration of the power supply between 120 and
220 - 240 volts AC:
1.
Switch the unit OFF.
2.
Remove the power plug from the AC wall outlet.
3.
Remove the power plug out of the rear of the unit.
4.
Switch the unit ON and verify that the front panel “Power” LED is
not lit. Switch the unit OFF.
5. Remove the front power supply card and locate the two position
switch near the back of the card. Slide the switch to the desired
voltage (Note: The actual values on the switch may be "110/220",
"115/230", or a similar indication).
6. Replace the existing fuse with one of the correct value (see
Section 5.2 for fuse replacement procedure and Appendix B for
the appropriate fuse).
7.
Replace the front card.
8.
Replace the power supply cord, if necessary (see Appendix B for
the appropriate power cord).
5.2 PROCEDURE FOR FUSE REPLACEMENT:
MODELS 1000RPEM AND 1000RPEM-V
Steps 1 - 5 in the instructions below apply to both models. Steps 6
- 10 are different for the Model1000RPEM than for the Model
1000RPEM-V.
(Steps #1- 5 for both models)
1.
Switch the front card OFF.
2.
Remove the power plug from the AC wall outlet.
3.
Remove the power plug out of the rear of the unit.
4.
Switch the unit ON and verify that the front panel “Power” LED is
not lit. Switch the unit OFF.
5.
DETERMINE THAT THE LINE VOLTAGE IS WITHIN THE
PROPER VOLTAGE RANGE SPECIFIED FOR THE UNIT. (A
RANGE OF 100 TO 130 VAC IS PERMISSIBLE FOR THE 120
VOLT SETTING. A RANGE OF 200 TO 240 VAC IS
PERMISSIBLE FOR THE 220 VOLT SETTING.) IMPROPER
VOLTAGE SETTING WILL RESULT IN DAMAGE, IMPROPER
FUNCTIONING, OR BOTH. Improper voltage setting is also the
leading cause for a blown fuse. If the voltage setting switch was
incorrectly set, see Section 5.1 for the instructions for proper
setting of the power line voltage selector switch and continue from
there.
(Steps #6 - 9 for Model 1000RPEM)
6.
Using a small screwdriver, pop the compartment open: It will slide
open like a drawer. Depending upon the exact part used, the
drawer may slide completely out of the fuse holder or it may stop
part way out. Note that there are two fuses in the drawer: The
front fuse is the spare, the rear fuse is the "active" fuse.
7.
If the active fuse appears to be blown, remove it from the clips and
replace it with the spare from the front compartment. Note the size
and rating of the blown fuse before discarding (*120V = TO.4;
240V = TO.2).
(continued)
WARNING!
To avoid electric shock, always remove
AC power cord before servicing front or rear card of
power supply module.
WARNING!
When you change the voltage setting,
you must also replace the fuse according to the
instructions in Section 5.2
7
8
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 will be marked
on the rear panel of the unit*). Replacing the fuse with
one having an incorrect rating can result in a fire!
