Explanation of the freezer alarms generated in the freezer facility in ANA Futura

When the freezer temperature rises, an alarm is generated by a system called SCADA. Currently an alarm is passed to the alarm receiver of the freezer. These are designated by the freezer's owner.

In case of an alarm, an email and a text message will be sent to designated alarm recipients.

Alarm Explanations

B alarm / internal alarm (active) = Alarm from the freezer's internal alarm. This can be caused by a power disruption in the freezer or by too high temperature. This applies to freezers with and without PT-100 sensors.

B alarm / internal alarm (inactive) = "Inactive" means that the freezer's internal alarm has reverted. This applies to freezers with and without PT-100 sensor.

A-alarm (active) "high or high-high temperature" = means that the temperature has exceeded the alarm limit i.e., the freezer is warmer than -65 (high) or -60 (high-high). This only applies to freezers with PT-100 sensor.

A-alarm (inactive) "high or high-high temperature" = "inactive" means that the temperature alarm has reverted. This only applies to freezers with PT-100 sensors.

Viewing the temperature in the freezer / isothermal in real time

If the freezer / cryo container has a PT-100 sensor, you can log in to the SCADA system and see the temperature of the freezer / cryo container in real time and view the temperature history.

Please note! This service is only offered to those who have a freezer / cryo container with a PT-100 sensor. Without a PT-100 sensor, there is no real-time logging of the temperature and there is no value in having access to the SCADA system.

I have a PT-100 sensor - how do I log in to the SCADA system?

Contact the service team (see contact details below). They need your KI ID and can then grant you permission to log in.

I have no PT-100 sensor but want it connected. How do I get it?

A PT-100 sensor costs about 5000 SEK for the sensor and installation (the price may vary depending on the freezer / cryo container). Contact the service team to make an order.

Please note - to install a PT-100 sensor, the freezer must be thawed before installation.
