Patton electronic 1000RP user manual Service Procedures, Steps #1- 5 for both models

5.0 SERVICE PROCEDURES

This section describes the procedures for Power Line Voltage Settings and Fuse Replacement for Patton Models 1000RPSM-2, 1000RPEM, 1000RPSM-Vand 1000RPEM-V. Note: These procedures apply generally to all products listed above, which (products) will henceforth be referred to as “the unit”.

WARNING! To avoid electric shock, always remove AC power cord before servicing front or rear card of power supply module.

5.1PROCEDURE FOR POWER LINE VOLTAGE SETTING: MODELS 1000RPSM-2 AND 1000RPSM-V

WARNING! When you change the voltage setting, you must also replace the fuse according to the instructions in Section 5.2

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).

5.2PROCEDURE 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.

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!

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).
