Ym calibration
This parameter is only possible for dosing output positioner with
feedback.
Adjust the positioner feedback signal to 0 % and 100 % dosing
rate. When automatic Ym calibration is started, the positioner
moves to positions 0 % and 100 % and calibrates both positions
with the MFC.
For manual calibration of the 0 % and 100 % positions, both
positions must be shifted to manually and saved in the menu using
the enter key (Ym calibration 0 %, Ym calibration 100 %).
Flow rate source
This parameter is only available during single feed forward control
of module 1.
This parameter switches off the flow input (off) and activates the
flow rate signal for the single feed forward control (factory setting
= flow measurement) as control variable.
The parameter must be set to "Flow Measurement" for quantity-
proportional dosing.
Flow direction
This parameter determines the direction of the flow rate signal
directly proportional to the actuator output:
Direct
= flow rate input signal directly proportional
to actuator output (factory setting)
inverse
= 1 flow rate input signal
Example:
0–100 % flow rate = 0–20 mA (direct)
0–100 % flow rate = 20–0 mA (inverse)
Control variable 2
This parameter activates and deactivates a second control
variable during the single feed forward control.
If "Control Variable 2" = measured value X is selected, this
influences the actuator output. The setting "Off“ indicates this
control variable is inactive (factory setting) (see 4.5.1 “Single Feed
Forward Control" on page 77).
X direction
Determines the direction of the second control variable during the
single feed forward control.
Direct
= measured value directly proportional to the
actuator output
inverse
= actuator output indirectly proportional to
measured value(factory setting = direct)
X factor
This parameter is only available during single feed forward control,
control variable 2 = measured value X.
Determines an adjustment factor, how strongly the measured
value influences the actuator output (factory setting 1.0).
