8.5 Application functions
BoosterControl Advanced has many useful features that are described in this section:
8.5.1 Setting the parameters for dry running protection
Table35: Parameter settings for dry running protection
Parameter Description Default Possible values
3-3-2 Configuration of suction side
BoosterControl Advanced reboots; observe notes
Setting of suction-side pressure transmitter
- Pressure switch
Pressure sensor
Flow monitoring
3-4-1-1 Calibrate suction-side pressure sensor at 4mA 0 kPa -1 ... 99,99 Bar
3-4-1-2 Calibrate suction-side pressure sensor at 20 mA 1000 kPa 0 ... 99,99 Bar
3-4-2-1 Calibrate discharge-side pressure sensor at 4mA - -1...99,99 Bar
3-4-2-2 Calibrate discharge-side pressure sensor at 20 mA - 0...99,99 Bar
3-5-15 Minimum pressure before dry running protection is
activated
- 0 ... 1000 kPa
3-5-16 Minimum pressure before system restarts after
having been tripped by dry running protection
device
- 0 ... 1000 kPa
3-6-8 Stop delay for system tripped by dry running
protection device
- 0 ... 10 s
3-9 Deactivate the "No water" message in the field list
(then the fault is self-acknowledging)
- -
If a pressure switch is used as a dry running protection device, also set the following
parameters.
8.5.2 Setting an alternative setpoint
If a second setpoint is required at certain times, an alternative setpoint can be set.
The alternative setpoint can be activated either once a day or once a week. Non-
relevant parameters are automatically hidden.
12) The differential constant is always zero.
