ATS Setup
Press the ENTER key when the selector arrow rests at the ATS Setup item to change the following settings:
Transfer Points The point, when sensing the voltage, that you would transfer to the other source. Based
on voltage and frequency.
• S1-Utility: The input voltage reading for Source 1.
• Low: The low voltage limit that causes the ATS to switch from Source 1 to Source 2.
Press the
ENTER key to change this setting.
• High: The high voltage limit that causes the ATS to switch from Source 1 to Source 2.
Press the
ENTER key to change this setting.
• Other Settings: The settings on this screen determine when the source is OK, and
define the quality of the source. Press the
ENTER key when the selector arrow rests at
this item to change the following settings, or thresholds:
–Freq: The frequency cannot vary beyond this configured range (+/– x.xx Hz).
–Phase Balance: The percent voltage difference between two phases cannot exceed
this configured setting (%).
–Phase Sequence: The phase rotation (default is A-B-C) must match this configured
setting.
Transfer Setup The following settings can be changed in this menu:
• Open Xfers: Defines the how long BOTH the Source 1 and Source 2 switches will be
OFF (open) during an open transfer. See page 8 for a definition of open transfers.
• Allow Closed: Enables/disables closed transfers. See page 8 for a definition of closed
transfers.
• Max Sync: The maximum time the ATS attempts a closed transfer before it performs
an open transfer.
• ATS Delay Settings: The time delay settings that affect transfers and re-transfers.
–Gen Start: The amount of time between when the generator receives a start signal
and when the generator starts (default is 0).
–Line Stable: If the ATS switches to Source 2 after a failure in Source 1, and Source 1
is restored, the Line Stable setting is the amount of time (in seconds) that Source 1
has to be good for before returning to Source 1 (default is 3 minutes).
–Min on Gen: The minimum time that the generator must run before the ATS
re-transfers to mains (default is 15 minutes).
