Series 668xA Supplies

The line fuses are located on the rear panel (see Figure 2-5). Proceed as follows:

l. Turn off the front panel power switch and remove the input power (unplug the power cord or open the safety disconnect).

2.Remove the ac input safety cover from the rear panel.

3.Unscrew the fuse caps and remove the fuses.

4.If one or two fuses are defective, replace all three with fuses of the same type (see Table 1-5 in Chapter l).

5.Turn on the power supply and check the operation. If it is normal, replace the ac input safety cover.

Series 669xA Supplies

The line fuses are located on the rear panel (see Figure 2-6). Check the fuse indicator window on the rear of the ac input safety cover. If the RED indicator is visible in the window, proceed as follows:

l. Turn off the front panel power switch and remove the input power (unplug the power cord or open the safety disconnect).

2.Remove the ac input safety cover from the rear panel.

3.Flip the fuseholder levers down and check the fuses. If a fuse has blown, the indicator pin will extend out of the center of the fuse body (see Figure 2-5)

4.If one or two fuses are defective, replace all three with fuses of the same type (see Table 1-5 in Chapter l). If all three fuses are blown, the power supply probably has a defect that requires service.

Note: When installing the fuses, make sure that the fuse indicator pin located in the center of the fuse is facing OUT, not IN.

5.Replace the ac input safety cover.

6.Turn on the power supply and check the operation.

Maintenance Note It is recommended that new line fuses be installed every four years.

Error Messages (All Models)

Power supply failure may occur during power-on selftest or during operation. In either case, the display may show an error message that indicates the reason for the failure.

Selftest Errors

When a selftest error occurs, it prevents all front panel operation. The display may show either a power-on error message or a checksum error message.

Power-On Error Messages

Power-on messages appear as: En- - - - - -

Where "n" is a number listed in Table 3-3. If this occurs, turn the power off and then back on to see if the error persists. It is possible to recover from the EE CHKSUM error (see "Checksum Errors"). If any other message persists, the power supply requires service.
