MM300 MOTOR MANAGEMENT SYSTEM – INSTRUCTION MANUAL
The home page represents the root of the entire menu structure. An overview of the
system status is displayed which includes the following items.
• Locked out, tripped, blocked, stopped, pre-contactor, starting, running status, and
inhibit.
• Motor load, thermal capacity used, and power.
• Estimated time to trip (if motor is loaded above its service factor).
• The longest current timeout from any of the pre-contactor time, time to overload, time
to reset, starts/hour block, time between starts, transfer time, undervoltage restart
time, and restart block timers.
• Temperature of the hottest stator RTD (if there is an RTD and the two previous items
are not applicable).
• Average line-to-line voltage (if there is no RTD).
Figure 3-7: Typical MM300 home display
The Values, Status, Setpoints, Diag, and Control soft-keys are displayed on the home
page. The Status soft-key will be highlighted red if any trip conditions are active, orange if
relay is not tripped and any alarm conditions are present. Otherwise it will be grey. If the
'tripped LED flasher' setpoint is set to 'ON', the softkey will flash red if there is a trip or
lockout.
Pressing any of the soft-keys displays the first sub-page in the hierarchy. Pressing the ESC
key within any of these sub-pages returns directly to the home page.
The default display is automatically shown when no control key has been pressed for five
minutes. It can also be recalled at any time by double-clicking the HOME key.
The default display can be set to the home page, any actual values page, or any status
page. A page can be set to be the default display by navigating to that page and double-
pressing the ENTER key. The default display setting is saved in non-volatile memory.
If a page is set as the default display, the soft-keys will be those of the selected page.
The actual values pages are divided into five sections.
• Summary (overview of primary actual values)
• Amps (metered current values)
• Volts (metered voltage values)
• Power (metered power values)
• Sensor (metered temperature and thermistor values)
The actual values summary page displays a summary of the analog actual values. The
current, voltage, power, and sensor actual values pages are accessible from the summary
page through the corresponding soft-keys at the bottom of the screen.
Some typical actual values screens are shown below.
