Alarm trigger function Single-event alarm triggering The upper or lower alarm triggering is done with a single-event alarm algorithm. Any kind of alarm is triggered if the temperature is continuously out of the preset alarm limits for longer than the preset alarm trigger time. Upper alarm triggering Setting upper limit: Temperature >8.0°C, duration >10 hours For the upper alarm to be triggered the temperature needs to be continuously above 8°C for more than 10 hours. Alarm triggered: alarm symbol and warning symbol displayed. In the example below the sum* of the daily upper temperature deviation is about 20 hours. No alarm will be triggered! The temperature was not continuously out of the preset alarm limits for more than 10 hours in one row. No Alarm triggered: OK symbol on the display. *The sum of the deviations is visible in the daily statistics in the column “Cumulative daily time above the limit.” Page 31 of 58 Berlinger &amp; Co. AG User Manual Fridge-tag 2 L - 1_en Lower alarm triggering Setting lower limit: Temperature <–0.5°C, duration >1 hour For a lower alarm to be triggered the temperature needs to be continuously below –0.5°C for more than 1 hour. Alarm triggered: alarm symbol and warning symbol displayed. In the example below multiple low temperature deviations* are occurring. No alarm will be triggered. Each temperature deviation was less than 1 hour out of the preset alarm limits. No Alarm triggered: OK symbol on the display. *The sum of the deviations is visible in the daily statistics in the column “Cumulative daily time below the limit.” Page 32 of 58 Berlinger &amp; Co.

AG User Manual Fridge-tag 2 L - 1_en 10.2. Cumulative daily time above/below the limit The alarm trigger algorithm is based on a single event, although the Fridge-tag is measuring on a daily basis the individual total time above or below the temperature limits. This measurement is not used for any alarm condition. These recordings are only available in the generated PDF/ASCII files. Note: It could be that the total cumulative time above/below the temperature limits is longer than the configured single-event alarm time without any alarm triggering. Example setup: lower temperature limit <–0.5°C, duration >1 hour In the above example multiple low temperature deviations with exposure times of less than 1 hour occurred. The cumulative daily time below the limits adds up to about 3.5 hours but no alarm will be triggered. The same behavior also applies to the upper alarm. Page 36 of 58 Berlinger &amp; Co. AG User Manual Fridge-tag 2 L - 1_en 11. Audio alarm (optional factory setting) In case an upper or lower alarm is triggered, 3 audible alarm signals are emitted immediately.

Explanations of terms Readout mode: In order to avoid incorrect data, the Fridge-tag does not measure the temperature while settings are changed or during or Readout mode (e.g. changing time, date and during reading of history). The Fridgetag will fall back into normal operation after approx. 60 seconds without pressing any buttons. External sensor: After 10 minutes (factory setting) without connection between external sensor and device, two audio signals sound every three minutes for a maximum of 168 hours (7 days) and the entire display starts flashing. HI or LO indicator (external sensor): If the Fridge-tag measures temperatures above +55°C or below –40°C, it shows HI or LO on the screen. The temperature will not be logged and not be shown in the PDF/ASCII file. The regular measurements and monitoring of alarm limits will continue as usual. As soon as the temperature is between +55°C and –40°C numbers will be displayed again. Page 55 of 58 Berlinger &amp; Co. AG User Manual Fridge-tag 2 L - 1_en 14.
