7.2.2 Adjusting the control range via potentiometer “Pband” 

The control response can be adjusted to the system conditions with this setting 
- small control range = greater amplification and shorter control times 
- big control range = longer control times and higher controller stability 
 

♦

  At active sensors with 0-10 V or 4-20 mA (factory setting) 

5-30 % ^ 5-30 % of measuring range of the sensor 
Setting range: 
E.g., pressure control with PKDM: 

 

Pressure sensor, type MBG-30I (0-30 bar, measuring range 30 bar) 
Setting 10 % ^ 3 bar 

 

♦

  At passive temperature sensor TF.. (KTY10-6) 

 

- PKDT5  

5-30 % ^ 4 ... 24 K (5-30 % of device´s measuring range 0-80° C)  

 
- PKDM  

5-30 % ^ 5 ... 30 K (5-30 % of device´s measuring range -25 ... +75° C) 

 

7.2.3 Min. speed „n-min“ (minimum output voltage or basic speed)  

If required setting of a minimum output voltage, e. g. basic speed (minimum airflow rate) of connected fans. 
Setting range:  
From the counter-clockwise limit = “0“ (no “n-min“) to 15-100 % (^ approximately the mains voltage applied). 

 
 

7.2.4 Max. speed „n-max“ (derating) and Cos 

φ

-adjustment 

If required setting of a maximum output voltage, e. g. speed limiter.  
Setting range: 
From the clockwise limit (100 %) to 20 % (^ approx. 100 % -20 % of the applied mains voltage). 
For a given minimum output voltage to the setting “n-min“. For cos 

ϕ

 adjustment, turn “n-max“ counter-

clockwise such that the maximum output voltage will just be measured (with TRUE-RMS multimeter). This 
adjustment must be made for maximum output from the fans. All flaps must be opened when using 
centrifugal fans. 
 
 
 

Cos 

ϕ

 adjustment  

The output voltage from the unit depends on the inductance of the motor (cos 

ϕ

). By this, the 

maximum output voltage can already be reached below the maximum input signal  
(<10 V / 20 mA). A correction is possible by setting “n-max" (cos 

ϕ

 adjustment).
