Operational types
In this table you can find the differences
of the automatic transfer switch open
and delayed transition operation types.
Due to the different transition types, there
are variances with HMI and on wiring of I/O
contacts.
HMI
The HMI is the control interface
(Human Machine Interface) of the ATS.
Zenith ZTS T-series has a color touch
screen LCD HMI with push buttons.
The HMI is used for configuring
parameters for automatic operation.
