Page 10: Alarm And Operating Messages For Each Bms Channel
Functional description Monitoring of the IT system transformer For temperature monitoring, the isoMED427P-PT device evaluates the resistance value of the temperature sensor. If the switching threshold of 4 k (isoMED427x) or the set temperature value (isoMED427P-PT) is reached, an overtemperature alarm is triggered. The display shows " > °C". ADVICE Temperature values are only displayed on the isoMED427P-PT. -
