Maintenance
– This screen contains data and settings pertaining to the
operation hours and maintenance period for the vacuum pump and refrigeration
system. Scroll up and down to view the entire page.
Line Voltage Offset
- These offset values determine the acceptable voltage
range for electrical power supplied to the Freeze Dryer. If the supply line
voltage is outside of the acceptable range, then the Line Voltage Range alert
will be displayed. The default range is +/- 10% of the nominal rated voltage
(115V or 230V depending on model). The LOW Line Voltage Offset can be
adjusted from 0 to -10V (115V models) or 0 to -20V (230V models). The
HIGH Line Voltage Offset can be adjusted from 0 to +10V (115V models) or
0 to + 20V (230V models). Scroll up and down to view the entire page.
Vacuum Pump Protection
– If vacuum pump protection is turned ON, the
vacuum pump will automatically be turned off if a “Vacuum Leak” alert is
presented. This will protect oil filled pumps from losing their oil and
potentially damaging the pump in the event of a major vacuum leak.
The
factory default setting for vacuum pump protection is ON, and it is highly
recommended that it remain in the ON setting.
If vacuum pump protection
is turned OFF, the pump will continue to run after a “Vacuum Leak” alert is
presented (i.e. there is no protection for the pump in the event of a major
vacuum leak).
