12.6 Pump status, diagnostic information
network output SNVT_dev_status nvoPumpStatus;
This network variable output provides detailed diagnostic
information on the status of the pump controller.
Pump status, diagnostic information
Bit name
Description
A pump- or controller-related fault or
warning has been detected.
device_fault
See section
detailed information.
A system-related fault or warning has been
detected.
supply_fault
See section
detailed information.
The controller is not controlled via the LON
local_control
network. It has been set to local mode by
hardware override from the controller.
The controller is running (does not
running
necessarily mean that any pump is running).
When transmitted
This value is transmitted immediately when it has changed.
Additionally, this network variable will be transmitted as a
heartbeat output on a regular basis as specified by the maximum
send time nciSndHrtBt configuration property.
12.7 Pump differential pressure (standard range)
network output SNVT_press nvoPressure;
This network variable output provides the differential pressure
across the system flanges as measured by the controller using a
differential-pressure sensor or as an estimated pump differential
pressure collected from Series 2000 pumps connected to the
controller (TPE Series 2000).
If the maximum pump differential pressure is higher than 3200
kPa, nvoPressureF should be used as it offers an extended
range.
Section
5. Considerations when installing the controller
more information on the coherence of nvoPressure and
nvoPressureF.
Valid range
-3,276.8 to 3,275.0 kPa (0.1 kPa).
The value of 0x7FFF (3,276.7 kPa) represents invalid data and
indicates that the pressure cannot be measured or estimated,
that no differential-pressure sensor is connected or that the
differential pressure is higher than 3200 kPa.
When transmitted
This value is transmitted immediately when it has changed more
than 2 kPa.

12.8 Pump differential pressure (extended range)
network output SNVT_press_f nvoPressureF;
This network variable output provides the differential pressure
across the system flanges as measured by the controller using a
differential-pressure sensor or as an estimated pump differential
pressure collected from Series 2000 pumps connected to the
controller (TPE Series 2000).
If the maximum pump differential pressure is lower than 3200
kPa, nvoPressure should be used as it offers a higher resolution.
Section
5. Considerations when installing the controller
more information on the coherence of nvoPressure and
nvoPressureF.
Valid range
-3.40282E38 to 3.40282E38 Pa.
If no pump differential-pressure sensor is available in the system,
nvoPressureF will display a value of NaN (Not a Number).
When transmitted
This value is transmitted immediately when it has changed more
than 2 kPa.
12.9 Pump inlet pressure
network output SNVT_press nvoInletPressure;
This network variable output provides the system inlet pressure
as measured by the controller.
If no inlet pressure sensor is available in the system,
nvoInletPressure will display the invalid value.
Valid range
-3,276.8 to 3,276.6 kPa (0.1 kPa).
The value of 0x7FFF (3,276.7 kPa) represents invalid data and
indicates that the pressure cannot be measured or that no inlet
pressure sensor is connected.
When transmitted
This value is transmitted immediately when it has changed more
than 2 kPa.
12.10 Pump discharge pressure (standard range)
network output SNVT_press nvoDisPress;
This network variable output provides the system discharge
pressure as measured by the controller.
If the maximum pump discharge pressure is higher than 3200
kPa, nvoDisPressF should be used as it offers an extended
range.
Section
5. Considerations when installing the controller
more information on the coherence of nvoDisPress and
nvoDisPressF.
Valid range
-3,276.8 to 3,275.0 kPa (0.1 kPa).
The value of 0x7FFF (3,276.7 kPa) represents invalid data and
indicates that the pressure cannot be measured, that no
discharge-pressure sensor is connected or that the discharge
pressure is higher than 3200 kPa.
When transmitted
This value is transmitted immediately when it has changed more
than 2 kPa.
