9.3 WIRING
Before the start of the programming, wire the L1-L2-L3 input phases when using three phase equipment and wire the
L1-L2/N input phases when using single phase equipment.
Once the
“Pressure”
control mode is selected, that is after introducing the parameters of the Pressure control mode
table (section 9.1), wire the drive as seen in the picture.
(See Fig. 11.)
.
The RUN signal must be connected between the terminals 1 & 2, and the switch is always closed, the drive will start
automatically when given power. If the user wants to stop the operation with a selector, timer, etc.… Set up a free
potential contact in series between the terminals 1 & 2.
9.4 PROBE SI-PRESSURE TPDA CONFIGURATION
The user should customize the adjustment of the scale of the probe, fitting the facilities where the probe is set up. For
example, the user should connect the jumper 2 and open the jumpers 1 & 3 to adjust the probe between 0 and 250 Pa
on the pressure transducer SI-PRESSURE TPDA.
See Fig. 12 and 13.
9.5 “PRESSURE CONTROL” OPERATION MODE
1.
Close the RUN switch connected between the terminals 1 & 2 to start the drive. The display will show
and
the drive will increase the speed until reaching the objective speed. This speed is subjected to the pressure level
detected by the probe and the setpoint adjusted in
2.
If the overpressure level goes over the setpoint adjusted in
the drive will decrease the speed in order to keep
the pressure level close to the setpoint.
3.
If the pressure level goes below the setpoint adjusted in
the drive will increase the speed in order to keep
the pressure level close to the setpoint.
4.
If the user wants the drive to be always working, short-circuit the terminals 1 & 2 with a copper wire.
5.
While the drive is ON, the user can see the motor consume pressing the Navigator key
>2 seconds.
