2.5 Setpoints pages
The setpoints pages are divided into five sections.
•
Config (contains basic configuration setpoints)
•
Protection (contains the protection setpoints)
•
Control (contains the control setpoints)
•
Security (contains the password security setpoints)
•
Factory (contains settings used by GE Multilin personnel for testing and calibration
purposes.)
The
Home > Setpoints
page displays a warning message concerning unexpected
performance if setpoints are improperly changed. It is recommended that all relay outputs
capable of causing damage or harm be blocked before a setpoints change is made and it
is clear the relay is performing as intended with the new setpoints.

To streamline the setpoint entry process, the HHD will not display setpoints that are not
relevant at the specific instance. For instance, if a process interlock function is disabled,
the six setpoints associated with that interlock function will not be displayed. If all ten
process interlock functions are disabled, the MM300 will display on the HHD only 10
successive “Disabled” list items. If one of the interlock functions were then enabled, then
room is made on the display for the six setpoints which are now functional.
The setpoint pages are in a common format of twelve rows and two columns displaying
setpoint name, value, and units.
The
Home > Setpoints > Config > Motor
page is shown below.
