6.3.2 POWER SOURCE LOAD TEST
This paragraph describes the test to be used to verify that the power source is able to deliver
rated load. Additionally, the output metering function of the controller is also checked.
The test proceeds in the manner below.
1.
Set the Power Source for 3
φ
Output (1
φ
for the Model 115-ASX, 2
φ
for Models 120-ASX
and 140-ASX), Direct-coupled, CSC Enabled.
2.
Attach a full-rated load to the
φ
A Output Terminal (1
φ
Output Terminal for the Model
115-ASX). (Refer to the list in paragraph 6.2 for the proper load.)
3.
Set the output for full-rated voltage and close the Output Contactor.
4.
Verify that the output voltage remains constant (within load regulation limits) and that the
Output metering reads correct values.
5.
Open the Output Contactor.
6.
Repeat
for
φ
B and
φ
C (
φ
B for 2
φ
and 3
φ
systems only,
φ
C for 3
φ
systems only) outputs.
7.
Configure for 1
φ
Output and repeat above procedure.
8.
If the system is outfitted with transformer outputs, set the Power Source for 3
φ
Output
(1
φ
for the Model 115-ASX, 2
φ
for Models 120-ASX and 140-ASX), Transform-
er-coupled, CSC Enabled.
9.
Verify that the output voltage and Power Source meters read properly.
