AP9. PRESSURE CONTROL MODE – VSD1-P, VSD3-P

This  section  explains  how  to  configure  the

PRESSURE  CONTROL

control  mode.  This  mode  allows  the  drive  to

regulate the speed of the ventilator depending on the overpressure between to places.

9.1 PROGRAMMING

Use the next table to change to, or modify the pressure control mode.

Table “PRESSURE CONTROL”

1.

In order to make the regulation more dynamic, change the



o



parameters. Increase



until the output

is fast enough. The increase



as much as possible and stop before the system oscillates.

See section 9.2 for the setpoint configuration.

9.2 PRESSURE SETPOINT ADJUSTMENT

The  pressure  setpoint  is  adjusted  in  the



parameter. The  value  read  by  the  drive is  shown  in  the  only-read

parameter

, if the probe has a display the user will be able to see the value directly. This parameters are shown

as percentages and will translate to a different value of Pa, subject to the chosen scale of the probe.

ATTENTION:

If there’s a power loss while the ventilator is working and the RUN switch is closed,

the drive will enter the stop stage and show



on the display. Once the power is restored, if

the RUN switch is still closed, the drive will maintain the stop status. In order to start again, the

RUN switch must be opened and closed again. This operation can be modified setting the



mode in the

parameter.
