9.3.5 Temperature
You activate the monitoring of the module temperature with the parameter entry
/Environment/Extended/Temperature/Monitoring (0.24.01).
You can set the following values:
• Alarm
• Warning
• No monitoring
The current module temperature is shown in the parameter entry
/Environment/Status/Temperature (0.24.02).
9.3.6 Battery
You can switch the battery off for storage with the parameter entry
/Environment/Extended/Battery/Switch Off (0.25.01), and so substantially
lengthen the life of the battery in storage.
After a minimum operating period of 30 minutes after Power Up, SICLOCK
TC100 checks once whether the battery is switched off. If necessary, the battery
is then switched on automatically, and a message is output.
See Battery (Chapter 11.1).
Notice
If the supply voltage is switched off while the battery is switched off, the SICLOCK
TC100 loses the hardware time and the archives.
This command may only be executed by qualified personnel.
