5.1.3. "Adjust control performance" menu

Select menu

indicates available submenu.

Preparing for external control:

Connect the Pt100 external sensor to the socket in the socket

panel. It is normally not necessary to calibrate the sensor.

In special situations, a three-point calibration, for example, can be

performed with the "Adjust sensors" function (see page 83).

The buttons will display the current
settings.
Select parameters

Set new

values.

Internal parameters

External parameters

Internal/external control parameters

In most cases, the factory-set control parameters will be

adequate for achieving an optimal temperature sequence in

the item being controlled.

Adjustable control parameters give you the ability to adapt to

unusual processes.

Setting range:
internal/external
0.1 ... 99.9 K

Proportional range >Xp<

The proportional range is the temperature range below the

setpoint in which the heating capacity is controlled from 100 %

to 0 %.

Setting range:
internal/external
0 ...10000 s

Reset time >Tn<

(integral proportion)

Compensation for the control deviation that remains due to the

proportional controller. Reset times that are too small may lead

to instability. Reset times that are too large will make

compensation of the control difference unnecessarily long.

Setting range:
internal/external
0 ... 1000 s

Rate time >Tv<

(differential proportion)

The differential proportion shortens the adjustment time.

If the rate time is too small, equalization of an interference

value will be extended and you will experience large

overshoots when approaching a setpoint. If the rate times are

too great, you may experience instability (oscillations).

Setting range:
0.1 ... 99.9 K

Proportional range >Xpu<

The Xpu proportional range of the underlying controller is

needed only for external control.
