PID control (only Output 1 at Ft = PID)
Pb Proportional range Preset possibility only for Set-value 1
(°C or °F) which affects the first control output.
This value determines the bandwidth
(on both sides of the set-value) that
exist within the proportional control.
int integral action time Determines the integral behaviour of the
(0...999 sec) controller. The greater the deviation,
the higher the effect.
dEt Derivative action time Determines the differential behaviour of
(0...999 sec) the controller. The greater the deviation,
the higher the effect.
Sr Measurement rate Time between 2 consecutive
(1...10 sec) following measurements for the
calculation of dt. A smaller value
increases the response time.
rS Manual Reset With this parameter, the proporti-
(°C or °F) onal control deviation can be moved up /
down.
The value will be defined as the
same amount, but in the opposite
direction to the deviation detected.
A r Integralband Range (on both sides of the set-value)
(°C oder °F) within which the integral action time is
effective. The higher the value,
the greater the effect.
Cyt Zykluszeit Minimum time during which the out-
(1...500 sec) put relay is switched on and off.
drb Soft-start band If the temperature is outside the band
(°C oder °F) (on both sides of the set-value), a new
Soft-Start will be initiated.
(0 = deactivated)
dSi Dynamic set-value This value determines the stepwise
control (°C or °F) set-value increase from SET1.
(0 = deactivated)
dSt Clock time for dynamic clock time for dynamic set-value-
set-value cpntrol control with regard to dSi (SOFT-Start).
