5.21 Operating data archiving
5.21.1 Temperature recording
Temperature recording is only intended for systems that are not provided with higher-level temperature
recording (e.g. system centre / store computer). Temperature measurement of the return air/room air sensors in
both temperature zones and status of alarm, cooling, defrost, manual shutdown and door are saved to ring
buffer memory at intervals of 15 minutes over a period of one year.
Local temperature recording
Temperatures are recorded every 15 minutes in the internal flash memory of the UA 410 E AC. Recorded data
can be displayed by the local BT 300 x Operator Interface under Archive (Menu 5). Operating data can be read
out on a PC connected to the USB port (currently unavailable). A USB-A-B cable (optional accessory) is
required for PC readout, see operating instruction of LDSWin.
Temperature recording on system centre / store computer
The case controller records temperature at 15-minute intervals and transmits the data to the system centre /
store computer via the CAN bus.
5.21.2 Temperature recording to EU Regulation 37/2005
Temperature recording in compliance with EU Regulation 37/2005 on the monitoring of temperatures in means
of transport, warehousing and storage of quick-frozen foodstuffs intended for human consumption requires the
use of a separate temperature recorder, e.g. UA 410 L, see UA 410 L operating instruction.
5.21.3 Recording of t0, tc and relative humidity
Using the second analogue input the case controller can also record t0, tc as well as the relative humidity (for
configuration details see chapter On-off control). These values can be utilised for a controller analysis under
LDSWin. The measured values can be seen under the menu item 1-1.
A recording of the added channels is conducted via the system centre / store computer. Here the recording of
integral values (-100 °C.. +100 °C) already mentioned is carried out at two minute intervals.
The first analogue channel is also recorded at 2 minute intervals in the existing channel to corr.
5.21.4 Recording of messages and alarms
A maximum number of 25 messages and alarms of the case controller are recorded in a ring buffer with fault
report text, date/time of start of alarm and date/time of end of alarm.
ATTENTION
Violation of EU directive! This type of data recording fails to meet the requirements of the EU
directive 37/2005 for the monitoring of the temperature of frozen food in the means of transport as well
as storage and warehousing facilities. For details of data recording in compliance with the EU directive
see chapter Temperature recording to EU Regulation 37/2005.
