System Cut-offs
The System Cut-offs screen of System Settings allows the cut-off voltage and temperature levels
(operating ranges) to be set for the System 5000
.
TM
Cut-off Voltage: Allows a minimum and maximum voltage range that must be met to continue
normal operation. Two separate voltage ranges can be specified for System 5000 and GOES
TM
Radio operations. The battery voltage level is retrieved and checked at the beginning of each
scan period.
System 5000: If None is selected, all Tasks will be run regardless of the measured battery
voltage level. If the second option is selected, Tasks will only be run when the voltage
level is within the given range. If the voltage level is outside of the specified range, the
system will simply schedule the next scan and re-measure when that time arrives.
GOES Radio: If None is selected, all GOES Transmissions will be scheduled and run
regardless of the measured battery voltage level. If the second option is selected, GOES
Transmissions will only be scheduled and run when the voltage level is within the given
range. If the voltage level is outside of the specified range, the system will skip the
current transmission scheduling and re-measure on the next scan. Note that some GOES
Radios have a built-in cut-off voltage independent of this check.
Cut-off Temperature: Allows a minimum and maximum temperature range that must be met to
continue normal operation. If None is selected, all Tasks will be run regardless of the measured
temperature. If the second option is selected, Tasks will only be run when the measured
temperature is within the given range. If the temperature is outside of the specified range, the
system will simply schedule the next scan and re-measure when that time arrives. The
temperature is retrieved and checked at the beginning of each scan period.
