Mitsubishi Electric MN converter Operating Manual page 72

The various settings are explained below.
(6)
- (1) Minimum reporting period (mins.)
Set a period between 0 and 60 minutes in 1-minute increments as the error reporting interval.
Errors that occur during this period are all reported together when the end of the specified period is
reached.
After the errors are reported, the next notification occurs at the end of the next reporting period.
If no errors occur during this period, none are reported.
Counting of the reporting period begins when the setting is specified.
If the MN Converter is reset due to an event such as a change to the error notification setting, the
counting for the minimum reporting period is also reset and errors are reported as soon as the
countdown restarts.
Error A occurred
Error B occurred
Minimum reporting period
NOTE:
The maximum number of errors that the MN Converter can store during the minimum reporting
period is 50.
Once the limit of 50 errors is exceeded, the oldest entries in the log are deleted.
When more than 50 errors occur, only the number of excess errors is reported.
- (2) Call duration (secs.)
Set a period between 30 and 99 seconds in 1-second increments as the time for which the MN
Converter continues dialing a contact telephone number once it has started the notification process.
If the contact telephone does not answer before this period expires, dialing is cancelled and notification
fails. This function prevents long periods of continuous dialing.
NOTE:
Some modem models have a similar function. If this is the case and the modem's continuous
dialing period is shorter than the Maintenance Tool setting, dialing stops after the period set on the
modem.
Refer to your modem's instruction manual for details.
