In addition, the following steps should be taken into account or checked or actually
taken before the actual start of the self-optimization:
• Has the matching controller type been configured?
• Check or respectively adjust the control direction of the controller
• Can the actual value be influenced in manual mode?
• Only for steady controllers:
The function of the output (OutP -> OutA) has to be configured as controller
outlet 1 and must be scaled to 0 ... 100 %.
This means: Function (FnCt) = controller output 1 (9) zero point (0Pnt) = 0 end
value (End) = 100
Depending on the type of controller and the parameter settings, the controller
structure and certain parameters will be optimized:
Controller Parameter setting
type
rt > 0
dt = 0
Two-point
Pb1 = random
controller
all other settings
Start of Self-Optimization
Press keys (B) and (C) simultaneously (> 2 [s]):
The lower display will show a blinking „tUnE".
The self-optimization will be finished when the display automatically returns to the
normal screen. The duration of the self-optimization depends upon the controlled
system.
Cancelling of the Self-Optimization
Press keys (B) and (C) simultaneously.
This cancellation will not change any parameters.
Maintenance
Cleaning the front of the device
Use standard detergents or cleaning agents for cleaning the front of the device.
It has limited resistance against organic solvents (e.g. methylated spirit, benzine, P1,
Xylol or other). Do not use a high-pressure cleaner.
