Mixer control

Mixer control
Standard diagram
Function description
This function allows a mixer to be constantly controlled to a set value. The function can control a
three-position actuator or an actuator with 0-10 V input (continuous analogue signal).
Input variables
Enable
General enabling of the function (digital value ON/OFF)
Actual value
Analogue input signal for the current actual value T.ctrl
Set value
Analogue value specifying the set value for control
Offset set value
Analogue value specifying an offset for the set value
Initialisation run
Digital input signal, ON/OFF, to start an initialisation run
➢ The set value and the offset value can be fixed values (source: user) or they can come from
another source as variable values.
➢ Initialisation run: If the "Actual value" input variable is unused, then the value of input
variables "Set value + Offset set value" is issued in % as the set value for control.
Output variable "mixer 0 - 100 %" is aligned with this value. This allows a precise set
position in % to be specified for a mixer with 0 - 10 V input. The mixer can be set to an end
position by a start pulse at the input variables.
Parameters
Mode
Available for selection: Standard or Inverse
Set val for ctrl
T.ctrl set
Display: Specified set value (+ offset value)
if enable = off
Mixer position
Mixer action when Enable mixer = Off:
Available for selection: Open, Close, Unchanged
Mixer
Control speed
(only visible if the "Actual
value" input variable is
used)
Matching the control speed to the control loop (setting range 20.0 % -
500.0 %)
Initialisation run
Mixer position
(only visible if the "Actual
value" input variable is
unused)
For the initialisation run, you can specify whether the mixer first runs
to the OPEN or CLOSED position, or regulates immediately (select
"Unchanged")
Selections: open, closed, unchanged
