➢ In addition to the Standard mixer mode, Inverse mode is also available. With Inverse the
mixer opens as the temperature rises.
➢ In inverse mode, the mixer also operates inversely when enable = off, i.e. the mixer opens
when close is selected.
➢ The set value for control is also issued if Enable = Off.
➢ Mixer 0 – 100 %: Scaling of the analogue output: 0 = 0.00 V / 1000 = 10.00 V
➢ If the "Actual value" input variable is unused, then the value of input variable "Set value +
Offset set value" is issued in % as the Set value for control.
During the initialisation run, 100 % is shown when "Open" is selected and 0 % when "Close"
is selected.
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 remaining runtime counts down from 20 minutes when a dual output (mixer drive) is
linked to the Open/close mixer output variable. If a dual output is not linked, the remaining
runtime counts down from 2 minutes.
➢ If the runtime limit was deactivated in the mixer output settings, the remaining runtime
only counts down to 10 seconds and output pair control is not terminated.
➢ The remaining runtime (20 minutes) is reloaded if the mixer output is in manual mode, is
switched by a message (to dominant ON or OFF), changes its direction of control from
OPEN to CLOSE or vice-versa, or if Enable is switched.
➢ Mixer open / closed: If the runtime limit was deactivated, the mixers are still displayed as
open or closed after the renaming runtime is complete.
➢ If inverse mode is selected, the output variables "Mixer open" and "Mixer closed" are also
reversed. This means that if the mixer is completely closed after the remaining runtime is
complete, then the status "Mixer open" changes to ON.
➢ During a controller start, an initialisation run is also started automatically in accordance
with the parameter settings.
