Parameters 271
80.28 Pump nom speed Defines the nominal speed of the pump in rpm.
0…32767 rpm Nominal speed of pump. 1 = 1 rpm
80.29 Density Defines the density of the fluid to be pumped for the flow
calculation function.
0.00 … 32767.00
kg/m
3
Fluid density. 100 =
1kg/m
3
80.30 Efficiency Total efficiency of the motor/pump combination.
0.00 … 100.00% Efficiency. 100 = 1%
80.31 Flow calc gain Flow calculation gain for possible calculation correction.
0.00 … 32767.00 Calculation correction gain. 100 = 1
80.32 Calc low sp Defines a speed limit below which flow is not calculated.
0…32767 rpm Low speed limit for flow calculation. 1 = 1 rpm
80.33 Sum flow reset Resets the total calculated flow counter (parameter 05.08).
No No reset. 0
Reset Reset the counter. 1
81
81 Pump protection
Settings for pump protection functions.
See also section Protective functions on page 64.
81.01 Inlet prot ctrl Enables the primary supervision of pump inlet pressure and
selects the action taken when low inlet pressure is detected.
The selected action is taken only after the measured
pressure has remained below the pressure limit (81.03 AI in
low level) for longer than the value of parameter 81.07 Inlet
ctrl dly.
The pressure can be measured using an analog pressure
sensor or a pressure switch.
The input for an analog sensor is defined by parameter
81.02 AI measure inlet. With an analog sensor, a separate
action for “very low inlet pressure” can be defined using
parameter 81.05 AI in very low.
The input for a pressure switch is defined by parameter
81.06 DI status inlet.
Not used Primary inlet pressure supervision not used. 0
Alarm Detection of low inlet pressure produces an alarm after the
delay defined by parameter 81.07 Inlet ctrl dly expires.
1
Fault Detection of low inlet pressure trips the drive after the delay
defined by parameter 81.07 Inlet ctrl dly expires.
