OPERATION
Viewing Screens
The instrument displays various screens with bargraphs, numerical values, and relay status
throughout operation. There are two basic modes of operation: Automatic, which allows the
controller to function based on it’s programmed settings; and Manual mode, which disables
all automatic output functions. The controller initializes in Automatic mode. When manual
mode is entered, all outputs are suspended or frozen in their current state so that they can
only be changed manually. Although, totalization continues while in Manual mode. The
example screens that follow can be viewed in all modes of operation with only subtle
differences noticeable including button names and headings.
Relay Status Screen
To the right is an example of a
Relay Status screen as it would
appear in Automatic mode. The
screen displays the current state of
the relay, the total time the relay
has spent in the ON state and how
many times the relay has cycled
from OFF to ON. In Manual mode,
this screen allows for overriding the
relays and resetting the Hours and
Cycles counts. This is discussed
further in Manual Relay Control
(page 45.)
