How a test occurs
When a test is not in progress, the
ATS is waiting for a test to occur.
You initiate a test by scheduling a
test on the Test Schedule screen
on the display interface, or by
starting a test immediately
through the Run/View Test
screen on the display interface.
Once a test is initiated, the ATS
will start counting down until the
next test (Next Test item on the
Test Schedule menu). Once the
Next Test time expires, the ATS
will signal the generator to start.
The generator will crank in an
attempt to start. If the generator
does not start, the test fails and
the ATS will log that the test
failed. If the generator starts, and
the ATS determines that Source 2
is OK, the test will begin with the
configurable Warm Up time.
Once the Warm Up time expires,
the ATS will determine whether
or not you want to perform a
System Load Test, which is a test
that the generator will run with
the data center load applied to it.
If the test does not include a
System Load Test, the ATS will
proceed to the cooldown test
stage. If the test includes a System Load Test, the ATS will transfer to Source 2. The transfer can be open or
closed, depending on how the Allow Closed setting is configured on the ATS Setup menu. The load test will
occur for the length of the Loaded time, and once the loaded time expires, the ATS will retransfer to Source 1
and then proceed to the cooldown test stage.
During the cooldown test stage, the generator will run for the duration of the configurable Cooldown time.
Once the Cooldown time expires, the generator will stop and the ATS will log either that the test was successful
or that it failed. The ATS displays test results on the View Test Log menu on the Testing screen.
