Override setpoint for speed
network input SNVT_lev_percent nviOvdSpeed
This optional input network variable is used for the overriding setting of a speed
setpoint, e.g. for maintenance work. The value is set as a percentage of the
maximum value of the pump. If a valid range is received, the setpoint set via
nviPumpSetpoint or nviOvdPress is overwritten and speed controller mode
automatically set.
The pump is reset to normal condition by an invalid value in all overriding
nviOvdSpeed and nviOvdPress setpoint settings and a “Normal” setting via
nviPumpOvdStop.
An overriding setting is indicated in the nvoPumpOverride output network variable.
Value range
-163.84% – 163.83% (in 0.005% steps). 163.835% is an invalid value.
Values lower than 0% or higher than 100% are limited accordingly and
nvoPumpStatus.pump_ctrl.setpt_out_of_range is set.
Default value: 163.835%
Override setpoint for pressure
network input SNVT_press nviOvdPress
This optional input network variable is used for the overriding setting of
a differential pressure setpoint, e.g. for maintenance work. The value is set as
a percentage of the maximum value of the pump. If a valid range is received,
the setpoint set via nviPumpSetpoint or nviOvdSpeed is overwritten and the
constant differential pressure control mode is automatically set.
The pump is reset to normal condition by an invalid value in all overriding
nviOvdSpeed and nviOvdPress setpoint settings and a “Normal” setting via
nviPumpOvdStop.
An overriding setting is indicated in the nvoPumpOverride output network variable.
Value range
-3276.8 – 3276.6 kPa (in 0.1 kPa steps). 3276.7 kPa is an invalid value.
Values outside the valid range for the respective pump are limited accordingly
and nvoPumpStatus.pump_ctrl.setpt_out_of_range is set.
Default value: 3276.7 kPa
Remote pressure sensor input
network input SNVT_press nviRemotePress
This optional input network variable allows an external differential pressure
sensor to be used to control the pump. If a valid value is received, the pump
automatically switches to constant differential pressure control mode.
Control by means of an external sensor is indicated in the
nvoPumpStatus.pump_ctrl.remote_press network variable.
