Parameters 273
81.04
Very low ctrl
Enables the secondary supervision of pump inlet pressure,
and selects the action taken after very low inlet pressure is
detected. The selected action is taken only after the
measured pressure has remained below the pressure limit
(
) for longer than the value of parameter
. See the diagram at parameter
.
Note:
With a pressure switch, this parameter has no effect.
Not sel
Secondary inlet pressure supervision not used.
0
Fault
Detection of very low inlet pressure trips the drive.
1
Stop
Detection of very low inlet pressure stops the drive. The
drive will restart if the pressure rises above the limit.
2
81.05
AI in very low
Pressure limit for secondary inlet pressure supervision. See
parameter
.
0.00 … 32767.00
bar
Pressure limit.
100 = 1 bar
81.06
DI status inlet
Selects the digital input for connection of a pressure switch
at the pump inlet. The “normal” state is 1. If the selected
input switches to 0, the action defined by parameter
is taken after the delay set by parameter
expires.
Not used
No pressure switch connected.
1
DI1
Digital input DI1 (as indicated by
, bit 0).
1073742337
DI2
Digital input DI2 (as indicated by
, bit 1).
1073807873
DI3
Digital input DI3 (as indicated by
, bit 2).
1073873409
DI4
Digital input DI4 (as indicated by
, bit 3).
1073938945
DI5
Digital input DI5 (as indicated by
, bit 4).
1074004481
Const
Bit pointer setting (see

Pointer
81.07
Inlet ctrl dly
Delay for primary and secondary supervision of pump inlet
pressure. See parameter
0…600 s
Delay.
1 = 1 s
81.08
Inlet forced ref
Pump speed reference for parameter
,
.
0.0 … 32767.0 rpm
Speed reference.
10 = 1 rpm
81.09
Outlet prot ctrl
Enables the primary supervision of pump outlet pressure
and selects the action taken when high outlet pressure is
detected. The selected action is taken only after the
measured pressure has remained above the pressure limit
(
) for longer than the value of parameter
The pressure can be measured using an analog pressure
sensor or a pressure switch.
The input for an analog sensor is defined by parameter
. With an analog sensor, a separate
action for “very high outlet pressure” can be defined using
parameter
.
The input for a pressure switch is defined by parameter
.
Not used
Primary outlet pressure supervision not used.
0
No.
