10.2.7 Automatic control / speed manual internal (Menu Speed maunal) Function 7D
Switch over between automatic control to set target value (depending on the activation: Setpoint 1, Setpoint 2, Setpoint
external) and the default for manual operation set at the device.
Contact at digital input e. g. Digital IN 1 = D1-D1
Automatic control at opened contact ↔ manual operation at closed
contact D1 Inverting OFF
Automatic control at closed contact ↔ manual operation at opened contact D1 Invertierung ON
10.2.8 Reverse action of control function actual value>Set = n+ or actual value>Set = n- Function 8D
Switchover between: Increasing modulation during increasing actual-value and increasing modulation during sinking
actual-value.
The factory presets for the “Control function“ are dependent on the selected mode of operation (
F Controller Setup →
reverse operation of the control function.)
When switching over via a digital input, the device works with the opposite function than the one set there!
Example: Actual value>Set = n+ (increasing modulation during increasingg actual value)
contakt at digital input e. g. Digital IN 1 = D1-D1
Setting in Controller Setup
contakt at digital input e. g. Digital IN 1 = D1-D1
actual Value>Set = n+ at opened contact ↔ actual > Set = n- at closed
contakt D1 Inverting OFF
actual Value>Set = n+ at closed contact ↔ actual > Setl = n- at opened contact D1 Inverting ON
