4.2.2 Battery protection
The battery protection serves to avoid permanent damage to the battery by discharge.
For 12V DC systems, the setting range is 9.6-15 V DC, with critical stop without delay if voltage
stops, below 8 V DC. The setting range for 24 V DC systems is 19 to 27 V DC, with critical stop
without delay if voltage drops below 15 V DC or exceeds 31.5 V DC. Tolerances are ± 0.30 V DC.

4.2.1 Main Functions
Main switch
In order to start and stop the compressor the Main Switch can be set to On or OFF .
OEMs making an interface with custom design electronics via Modbus must be able to control the
CCU ON / OFF via the Main Switch.
ON: All functions are active.
OFF: All main functions are inactive, however
• Battery monitoring active
• NTC temperature sensor monitoring active
• Auxiliary temperature sensor monitoring active
• PCB inverter temperature monitoring inactive
Power consumption monitoring
Compressor power consumption is monitored at 10 minute intervals. The following information
can be viewed via the Tool4Cool
®
interface:
For single configuration, individual compressor power consumption
For twin configuration, combined compressor power consumption (application module + 2
compressor modules)
Power consumption for each compressor can also be logged.
Cumulative power consumption since startup
Cumulative power consumption last period
The user can reset power consumption to zero using the Reset power consumption function
