In this section describes the meanings of error and warning messages which may appear during the
operation of MP-11 and software, and how to correspond to these messages.
1. MP-11 Main Unit Error and Warning Message
Table 10-1. MP-11 Main Unit Error and Warning Messages
Messages Definitions and Corresponding
The Sensor Unit is not connected to the Main Unit with modular cable and/or
the Sensor Unit power is not turned ON.
Check the cable connection between the Main Unit and Sensor Unit make sure
they are connected properly and the Sensor Unit power is turned ON. Once
the proper connection is confirmed and time synchronization is completed, this
message will disappear automatically.
If the Sensor Unit is not used, press any key to remove this message.
The PV probes are connected with reverse polarity (plus/minus terminals), and
the measurement is terminated.
Check the PV probe polarity and reconnect as necessary.
MP-11 is not ready, and at least 30 seconds interval is required between each
measurement. This is to prevent MP-11 from aging faster by the internal parts
heating up constantly. Wait for more than 30 seconds before taking the next
measurement.
MP-11 is in
“not ready for measurement” mode continuously; wait for 10 more
seconds to be able to start the measurements.
The Open Circuit Voltage for PV module/array terminal to be measured more
than maximum voltage of setting range. Set upper voltage range and
measure again.
If the setting range is 1000V or Auto Range, measured voltage is over
maximum voltage to measure. Stop measurement immediately; it may cause
damage to MP-11.
The Short Circuit Current for PV module/array terminal to be measured is more
than maximum current of setting current range. Set upper current range and
measure again.
If the setting range is 30A range or Auto Range, measured current is over
maximum current to measure. Stop measurement immediately; it may cause
damage to MP-11.
