UDC100 PID OPTION MANUAL
1 - CONFIGURATION OF THE CONTROL ALGORITHM
Parameter
Action:
Direction of the control, direct or reverse acting.
Typically, reverse control is used for heating and direct control for cooling applications.
Proportional band:
Proportional action is used to achieve stable control and is expressed as the percentage of the input span
over which the output power level is directly proportional to the percentage of error between the PV and
setpoint.
Configurable from 0.0% (ON/OFF control) to 999.9%.
WARNING: The 0.0% value sets the UDC100 to ON/OFF control irrespective of the other parameter settings
e.g. integration and derivative times.
Integration time:
Integral action is used to eliminate any offset between the PV and SP due to proportional action.
Integral time constant configurable from 0 second (OFF) to 5999 seconds.
Setting the integral time to 0 will switch off the integral action.
This parameter is ignored if the proportional band is set to 0.0% (ON/OFF control).
Derivative time:
Derivative action is used to return the PV back to the SP in a quicker time period after a process disturbance.
The function is also utilized to limit the amount of overshoot of the PV during initial start up of a process.
The operation of the derivative action is based on the rate of change of the PV with reference to the SP.
Derivative time constant is configurable from 0 second to 5999 seconds.
Setting the derivative time to 0 will switch off the derivative action.
This parameter is ignored if the proportional band is set to 0.0% (ON/OFF control).
Cycle time:
Configurable up to 256s. WARNING : It is strongly recommended to avoid using cycle times below
5 seconds, otherwise the precision of the output activation timing is not guaranteed.
Max. rate:
Maximum output increase between two consecutive input/output updates configured from 0% to 100%.
Setpoint low limit:
Configurable minimum setpoint value.
Setpoint high limit:
Configurable maximum setpoint value.
Setpoint:
Setpoint value used for control.
Output power high limit:
Power output high limit configurable from 0 to 100% output.
Output power low limit:
Power output low limit configurable from 0 to 100% output.
2 - SETTING THE PID PARAMETERS VIA THE UDC100 MMI
In normal operating conditions, the upper display shows the process variable [PV], (i.e. : 100°C).
When push button 1 is pressed, the setpoint value (flashing) is displayed, (i.e. : 300 °C).
When push button 1 is pressed while the SP is flashing, the display shows «Cod». After 2 seconds, the current value is flashing to indicate that
the user must enter a security code by means of the setpoint knob, to enable access to the PID parameters.
The code is factory set and cannot be changed in the field. The default value is 10.
If the code is entered correctly, the next message is displayed.
If the UDC100 is a two loops model, it is possible to toggle between CH1 and CH2 by pressing push button 1.
When the proportional band menu appears, this parameter can be modified by waiting until the value flashes, the value can then be altered via
the setpoint knob.
Pressing push button 1 while message "Pb" is displayed gives direct access to the next parameter (the integral time constant), and the same
procedure above applies if the value needs to be modified.
Repeat the steps detailed above to modify the derivative time constant.
Used to set the output bias (manual reset) when the integral time constant parameter is set to 0.
Cycle time parameter is used to adjust the time proportional output to achieve optimum control.
Press push button 1 to return to the normal operating mode or wait for message "no" to appear, after a short time the UDC100 will return to
normal PID mode.
It is possible to toggle between "yes" and "no" by pressing push button 1.
Note: If "yes" is selected the UDC100 will enter into manual mode just after leaving configuration mode.
The UDC100 will remain in manual mode until "no" is reselected in configuration mode.

Resumen de contenidos para Honeywell UDC100

  • Página 1 Cycle time parameter is used to adjust the time proportional output to achieve optimum control. Press push button 1 to return to the normal operating mode or wait for message "no" to appear, after a short time the UDC100 will return to normal PID mode.
  • Página 2 The output bias parameter can be used to eliminate the offset between the PV and SP when the controller is in proportional and derivative mode. NB: The output bias (manual res et) parameter is accessible via the UDC100 MMI only when the integral time constant is set to 0.
  • Página 3 Configurable de 0.0% (régulation ON/OFF) à 999.9%. ATTENTION : La valeur 0.0% positionne l'UDC100 en régulation ON/OFF sans tenir compte du réglage des autres paramètres tels que les temps d'intégration et de dérivation.
  • Página 4 Si le code est correctement entré, le message suivant est affiché. Si l'UDC100 est un modèle 2 boucles, il est possible de passer de la voie 1 à la voie 2 en appuyant sur le bouton 1. Lorsque le menu de la bande proportionnelle apparaît, ce paramètre peut être modifié. Lorsque que la valeur clignote, elle peut alors être changée avec le bouton central.
  • Página 5 Le paramètre de décalage de sortie (bias) peut être utilisé pour éliminer le décalage permanent entre la valeur de procédé et le point de consigne quand le régulateur est en mode PD. Le paramètre de décalage de sortie (décalage manuel) est accessible par l'interface Homme-Machine de l'UDC100 uniquement quand la NB : constante de temps d'intégration est réglée sur 0.

  • Página 7 Während der Meldung "no" kann mit Taste 1 auf " yes" und wieder zurück geschaltet werden. Hinweis : Wird "yes" gewählt, geht der UDC100 nach dem Verlassen des Konfigurations-Modus in die manuelle Betriebsart. Er bleibt in der manuellen Betriebsart, bis im Konfigurationsmodus "no" gewählt wird.
