HANDHELD DISPLAY

MM300 only).
A typical display is shown below:
Figure 12: Typical status message page
Message types are classified by color and associated icon type, as follows::
•
Red Triangle = Trip
•
Orange Square = Alarm
•
Blue Circle = Inhibit
•
Black Text = Information Message
Message can have an associated countdown timer.
When the relay is first powered up, the status page lists why the relay is not available for
service. This is not an exhaustive list of setpoints to be configured, but is a list of key items
such as FLA, CT Type, starter type and control Source, that must be configured before the
unit will be available for use. Protection values must still be configured for the motor to be
protected correctly.
Inhibits
These include Process Interlock Stop, and Field Stop.
Trips / Alarms
These trigger depending on the protection setpoints. A typical example would be;
“Overload Trip”.
Information Messages
Information pages are split into two groups
–
With navigation (shown above, as an
Enter
symbol on the right side of the
display)
–
Without navigation
When a line showing a message (with navigation) is highlighted, pressing
Enter
will take
the HHD directly to the page in question, so that the situation can be quickly resolved. A
typical example would be “FLA not set”. Selecting this entry on the page will take you to the
\setpoints\config\motor page.
