Auto-Loaded System Test; Sync Check (Closed-Transition) - Kohler MPAC 1500 Manual

If the sources do not sync before the Fail to Sync time
delay expires, the programmed-transition override
function operates.
D
If the override function is set to Automatic, a
programmed-transition transfer will occur when the
Fail to Sync time delay expires. The contactor stops
in the OFF position for the length of the off-to standby
time delay before proceeding to transfer to the
standby source.
D
If the override function is set to manual, the user can
either initiate a programmed-transition type transfer
(setup password required) or cancel the test
sequence. See Figure 3-13. If neither action is taken,
the controller will

3.10.4 Auto-Loaded System Test

The auto-loaded test feature is a timed, loaded test. The
auto-loaded time delay determines how long after the
transfer to standby to terminate the test and transfer
back to the preferred source. The time is defaulted to
30 minutes and can be adjusted from 1 minute to
60 minutes. See Figure 3-14.

3.10.5 Sync Check (closed-transition)

The Sync Check allows a test of the synchronization of
two available sources without initiating a transfer.
Navigate to the Type of Test, Sync Check menu and
press the Start button to begin the test. The controller
displays Syncing during the test, and the phase angle
difference is shown between two arrows. For example,
> 10 < indicates that the sources are 10 degrees out of
phase. The arrows move closer together as the sources
approach synchronization.
synchronize, the controller indicates Synced and
continues to monitor the source synchronization. The
load is not transferred. See Figure 3-15. Press the End
Test button to end the test.
for
Time-stamped readings of source phase angle
differential, frequency, and voltage during the test are
logged in a SyncDataLog.csv file. Data readings are
logged approximately once every second for one
minute. Simply insert a flash drive into the controller's
USB port during the sync check test to save the file. See
Section 6.4 for more information about data files.
