Table 21 Terminology
Term Explanation
ARAVF Automatic Restart After Voltage Failure. Refer to controller.
Power recovery time
The time period that the voltage supply must be reconnected to
have an automatic restart. An automatic restart will only occur if the
automatic restart function has been started. To start the automatic
restart function, contact us.
Restart delay
This parameter permits to programme that not all pumps are restar-
ted at the same time after a power failure (ARAVF active).
Pump element outlet
The recommended minimum setting is 120 °C (248 °F). For testing
the temperature sensor, the setting can be decreased to
1
11 °C (232 °F). Reset the value after testing. The controller does
not accept settings that are not consistent. For example, if the warn-
ing level is programmed at 120 °C (248 °F), the minimum limit for
the shutdown level changes to 121 °C (250 °F). The recommended
difference between the warning level and shutdown level is 10 °C
(18 °F).
Delay at signal
Time period during which the warning signal must exist before the
warning message is shown.
Delay at start
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
When the pump is automatically stopped, it will stay stopped for the
minimum stop time, regardless of the system pressure.
Proportional band and
integration time
The settings for the proportional band and integration time are deter-
mined by experiment. Adjusting these settings can damage the
pump. Contact us.
