Motorized Linear Actuator baelz 373-E07
DIP10:
An actuator characteristic can be used indirectly to change a valve characteristic. If, for
example,thevalvehasanequalpercentagecharacteristic,aninverseequalpercentage
actuator characteristic can be used to generate a resulting linear characteristic, see illustration
below.
The actuator characteristic (DIP 10) can also be combined with the characteristics which
canbeselectedusingDIPs7,8and9(e.g.splitrange).Themicrocontrollerrstprocesses
thecharacteristicdenedbyDIPs7,8and9andsubsequentlythecharacteristicdenedby
DIP 10.
InModbusmode,twofurtheractuatorcharacteristicscanbeselected:equalpercentageand
quadraticinverseequalpercentage.
DIP11:
DIPswitch11denesthemodeofoperation:1=Modbusmode,0=standardmode.
Standardmodeisusedtoapplypredenednormalsettings.
DIP12:
Starts an initialization run when switched from 0 to 1. If DIP 12 is left in position 1 when the
7020 positioner is switched on, an initialization run will not be startet.
As long as DIP 12 is set to 1, errors and alarms occurring during normal positioner operation
will not be shown. This enables errors occurring during initialization to be distinguished from
errors during normal positioner operation. Switch DIP 12 back to 0 after the initialization run
(after having analysed possible error codes) to show any errors occurring in normal positioner
operationontheredLED.Seealsosection7.5.2"Initializationrun".
