Pump status diagnostic information
network output SNVT_dev_status nvoPumpStatus
This output network variable provides bit-coded information about the pump
status.
Value range
Transmission
This value is automatically transmitted whenever a change is made.
Furthermore, this value is transmitted regularly if the nciSndHrtBt configuration
input was described with a valid clock.
Transmission frequency
The minimum network variable transmission interval can be set by describing
the nciMinOutTm configuration input with a valid clock.
Preset service type: acknowledged
Pump Pressure
network output SNVT_press nvoPressure
This optional output network variable provides the differential pressure
between the pump flanges determined internally by the pump.
Value range
0 – 3276.6 kPa ( in 0.1 kPa steps). 3276.7 kPa is an invalid value.
Transmission
This value is automatically transmitted if it deviates from the value transmitted
last by more than 5% of the value in nroPumpChar.pressMax.
Bit
Description
device_fault
Pump error (see nvoPumpFault for detailed information)
supply_fault
Supply error (mains voltage, phase missing, dry run, etc.
See nvoPumpFault for detailed information)
speed_low
Lower control limit (pump is running at minimum speed, which
is why the required operating point cannot be achieved)
speed_high
Upper control limit (pump is running at maximum speed, which
is why the required operating point cannot be achieved)
setpt_out_of_range
Setpoint exceeded/fallen short of
local_control
Local operation (by ext. off, ext. min or IR monitor)
running
Pump is running
remote_press
Control by means of external pressure sensor
remote_temp
Control by means of external temperature sensor
