CAUTION
For these alarm functions to be effective, first enable them, then calibrate three times at
intervals of at least 5 days. After that the function will be effective.
9) Alarm 9: Inside temperature alarm
Using the averaging converter in the ambient temperature of more than 50
؇C may cause
a failure in internal electronic circuit. An IC temperature sensor is installed inside the
control card of the averaging converter and monitors the internal temperature constantly.
If the internal temperature exceeds the limit, an inside temperature alarm will be
generated. The limit is approximately 50
Њ C in terms of case ambient temperature. The
occurrence/cancellation time of this alarm is recorded for the last three times. The record
can be viewed in the Detailed Data display (Figure 12.14). For frequent occurrence of
this alarm, take a measure to lower the ambient temperature. By assigning the inside
temperature alarm to the contact output, a contact may be used as an On/Off switch for
cooling equipment (e.g., fan).
