4.5 Initial operation
4.5.1 Setup procedure
To enable the valve for
pressure control
setup
steps 1 to 7
must
be performed
.
In case position control is required only it’s sufficient to perform steps 1 to 4.
Setup steps Description
1
Power up
Turn on external + 24VDC power supply of valve (and external ±15
VDC for sensor power supply if required).
Refer to chapter «Behavior during power up» for details.
2
Interface
configuration
Refer to chapter «Logic Interface configuration» for details.
3
Valve
configuration
Basic configurations of valve must be adapted according to
application needs. Refer to chapter «Valve configuration» for details.
4
Sensor
configuration
Basic configurations of sensor(s) must be adapted according to
application needs. Refer to chapter «Sensor configuration» for
details.
5
ZERO
Compensation of the sensor offset voltage.
Refer to chapter «ZERO» for details.
6
LEARN
Determination of the vacuum system characteristic to accommodate
the PID controller. Refer to chapter «LEARN adaptive» for details.
7
PRESSURE
CONTROL
COFIGURATION
Accommodation of PID controller to the vacuum system
characteristic.
Refer to chapter: «Pressure Control configuration» for details.
Without «LEARN adaptive» or «Pressure Control configuration» the valve is not able to
run pressure control.
For ease setup (in Local mode) of ‘Interface’, ‘Valve’, ‘Sensor’, ‘Senor ZERO’, ‘LEARN’
and ‘PRESSURE CONTROL COFIGURATION’ it is possible to use the CPA 3.0, The
