Sources of power which do not continually produce at least 100mA
of current will cause the MPT-3024 to enter sleep mode.
17. Fault Messages
The MPT-3024 is designed with a variety of sensing capabilities that are meant
to make the microprocessor aware of a fault condition and allow it to shut the
controller down before damage results. On the rare occasion that the controller
shuts down due to the presence of a fault, an alert will appear on the LCD
display so that the user can take appropriate action before resuming operation
of the controller. Table 17.1.1 lists possible fault conditions, their correspond-
ing alerts, and the action required by the user for each. After correcting the
fault, power down the controller for 30 seconds before reapplying power.
18. Troubleshooting
If the MPT-3024 is not operating as expected, please review the list of
conditions and possible causes on pages 47-49 before requesting technical
support from RPT. Many problems can be traced to improper or insufficient
wiring, faulty connections, or adverse weather conditions.
