The Protection LED is lit when the MP-3000 is in the Protection mode. The MP-3000 provides
protection with the relay while in the Program mode; therefore, the only time the Protection LED
is extinguished is when the "DISARMED" feature is used and also for the brief time it takes to
calculate all setpoints when leaving the Program mode.
The Program LED is lit when the MP-3000 is in the Program mode.
The Trip LED is lit when a trip condition has occurred.
The Alarm , Aux 1 and Aux 2 LEDs are lit when these auxiliary relays are activated. (The
Program mode is used to specify what will cause these relays to activate.)
The remaining LEDs are on the mode select buttons and indicate the mode of the MP-3000
display - Monitor, View Setting, History, and Log. If none of these four LEDs is lit and the relay is
not in Program Mode, then the display is in the Motor State (Default) Mode.

of the motor and relay are displayed. The following events reset the system to Default mode:

Pressing any mode button a second time
Pressing the Reset pushbutton the required number of times to step out of Line, Page, or Mode
A change in the state of the motor, except when in the Monitor mode
An alarm or trip
When in the Motor State mode, The display normally shows READY--3 (stopped), START, or
RUN. If the relay is disarmed, the DISARMED display will alternate with the motor state See
Table 4.1. Self-diagnostics and trip or alarm data are also displayed. If more than one event has
occurred, the messages will alternate.
An alarm or trip will always return the display to the Default mode. As soon as any mode button
is pushed, the flashing stops and the Modes, Page, and Line displays are available. Returning to
the default display will again show the alarm and/or trip condition until the condition is cleared
and is acknowledged with the Reset pushbutton. If the relay is in Monitor mode when a change of
motor state occurs, the new state will flash on the display for 5 seconds and then the display will
return to the value being monitored.
4.2 Monitor Mode — The Monitor mode displays real-time data as shown in Table 4.2.
