Step Action
Expected
Result
1.
Make sure the AC source is turned off. Connect a DVM
across the sense terminals.
2.
Turn on the AC source with no load on the output.
Program the output for a 150 volt, 60 Hz sinewave,
external sense. Set the output current limit to its
maximum value. If the source you are verifying is in
three-phase mode, start by verifying output phase 1
(Ø1).
CV
annunciator
on.
Output current
near 0.
3.
Record voltage readings at DVM and on front panel
display.
Readings within
low voltage
limits specified
in Table 41.
4.
Program the voltage to 300 volts.
5.
Record voltage readings of DVM and on front panel
display.
Readings within
high voltage
limits specified
in Table 41.
6.
If the AC source you are verifying is in three-phase
mode, repeat steps 1 through 5 for output phases 2 and
3. Press Phase Select to select the next phase.
Table 39 : Voltage programming readback test steps
6.2.3 Current Programming and Readback Accuracy
This test verifies the current programming and readback. Connect the appropriate
current monitoring resistor (see Table 38) as shown in Figure 19. The accuracy of
the resistor must be as specified in the table.
Step Action
Expected
Result
1.
Turn off the AC source and connect the current
monitoring resistor as shown in Figure 19. Be certain to
use wire of sufficient size to carry the maximum rated
current of the AC source (see Table 6 in chapter 2).
2.
Connect a DVM across the resistor
3.
Turn on the AC source and program the output for 5 volts
and the Low Current value specified in Table 41. If the
AC source you are verifying is in three-phase mode, start
by verifying output phase 1
4.
Enable the output (Output On/Off or OUTP ON)
5.
Observe the DVM voltage reading. Divide this by the
resistance of the current monitor resistor. Record the
result as the Low Current value in Table 41.
Value within
low current
limits
specified in
Table 41.
6.
Record the front panel display readback.
Value within
readback
limits
specified in
Table 41.
