Diagnostics View
See Figure 42, p. 90.This window lists the active and
inactive (history) diagnostics.There can be up to 60
diagnostics, both active and historic. For example, if there
were 5 active diagnostics, the possible number of historic
diagnostics would be 55.You can also reset active
diagnostics here, (i.e., transfer active diagnostics to
history and allow the chiller to regenerate any active
diagnostics).
Resetting the active diagnostics may cause the chiller to
resume operation.
The Active and History diagnostics have separate tabs. A
button to reset the active diagnostics displays when either
tab is selected.
Configuration View
See Figure 43, p. 91.This view displays the active
configuration and allows you to make changes.
Configuration View allows you to define the chiller's
components, ratings, and configuration settings.These
are all values that determine the required installed
devices, and how the chiller application is run in the main
processor. For example, a user may set an option to be
installed with Configuration View, which will require
devices to be bound using Binding View. And when the
main processor runs the chiller application, the
appropriate steps are taken to monitor required inputs and
control necessary outputs.
Any changes made in the ConfigurationView, on any of the
tabs, will modify the chiller configuration when you click
on the Load Configuration button (located at the base of
the window).The Load Configuration button uploads the
new configuration settings into the main processor.
Any changes made to the configuration will change the
unit model number and the confirmation code (CRC). If
changes are made to the unit configuration the new model
number and CRC should be recorded.
Selecting the Undo All button will undo any configuration
setting changes made during the present TechView
connection and since the last time the Load Configuration
button was selected.
