5.4.2 Initialization parameters 1 to 5 (PA and FF)
Introduction
Parameters 1 to 5 are the same for all versions of the positioner. These parameters are used to adjust the positioner to the
actuator. Normally, setting these parameters is sufficient to be able to operate the positioner on an actuator.
If you want to get to know the positioner in detail, gradually try out the effects of the remaining parameters by systematic
testing.
Note
Factory-set parameter values are printed in bold in the following table.
Overview
Parameter Function
1.YFCT Type of position actuator
2.YAGL Nominal angle of rotation of the feedback message
3.YWAY Range of stroke (optional setting)
2)
4.INITA Initialization (automatic)
5.INITM Initialization (manual)
Set the transmission ratio selector accordingly.
1)
Parameter only appears with "WAY", "-WAY", "ncSLL", and "-ncLL"
2)
If used, the value on the actuator must correspond to the set range of stroke on the lever arm.
3)
Carrier must be set to the value of the actuator travel or, if this value is not scaled, to the next larger scale value.
5.5 Purge air switching
When the enclosure is open, the purge air switch above the pneumatic terminal strip on the pneumatic block can be
accessed.
● In the IN position, the enclosure is flushed from inside with a small volume of clean and dry instrument air.
● In the OUT position, the purge air is directly directed towards outside.
