Terminology
TERM
EXPLANATION
ARAVF
Automatic Restart After Voltage Failure. See section Airlogic controller.
Power recovery time
Is the period within which the voltage must be restored to have an automatic
restart. Is accessible if the automatic restart is activated. To activate the
automatic restart function, consult Supplier.
Restart delay
This parameter allows to programme that not all Vacuum pumps are restarted at
the same time after a power failure (ARAVF active).
Vacuum pump element
outlet
The recommended minimum setting is 110 °C (230 °F). For testing the
temperature sensor, the setting can be decreased to 50 °C
(122 °F). Reset the value after testing. The controller does not accept
inconsistent settings, e.g. if the warning level is programmed at
95 °C (203 °F), the minimum limit for the shut-down level changes to 96 °C (204
°F). The recommended difference between the warning level and shut-down
level is 10 °C (18 °F).
Delay at signal
Is the time period during which the warning signal must exist before the warning
message appears.
Delay at start
Is the time period after starting which must expire before generating a warning.
The setting should be less than the setting for the delay at signal.
Minimum stop time
Once the Vacuum pump has automatically stopped, it will remain stopped for the
minimum stop time, whatever happens with the system pressure.
Proportional band and
integration time
The settings for the Proportional band and integration time are determined by
experiment. Altering these settings may damage the Vacuum pump. Consult
Supplier.
