Manufacturer objects description
11.5.1.1.
2001h Pressure regulation check mode
Sets the type of event, warning or alarm, in case
the regulated pressure doesn’t reach the target
value.
See parameter “Pressure regulation check timeout”. In the event of a warning, pressure
regulation is not interrupted; on the other hand, in the event of an error, pressure regulation is
interrupted.
11.5.1.2.
2002h Enable pressure regulation check
Enables to control the regulated pressure. This control is similar to the "window" function of the
digital output (for more details regarding this function, refer to paragraph "Digital output"): the
regulator checks if the regulated pressure reaches the pressure target within a certain settable time
(Pressure regulation timeout). This control uses the values "Negative window level" and "Positive
window level" to determine the tolerance range on the regulated pressure.
11.5.1.3.
2003h Pressure regulation check timeout
Serves to set the timeout value for the pressure regulation check.
Refer to the “Enable pressure
regulation check” parameter
.
11.5.1.4.
2004h Pressure regulation protection timeout
Sets the inactivity time of the regulator when the target pressure is not reached before the
expiration of the Pressure regulation timeout. During the period of inactivity, the regulator
maintains the current pressure without trying to reach the target pressure. After this inactivity time
has expired, the regulator will try again to reach the target pressure. Use this parameter if you want
to avoid that the regulator keeps the internal valves activated for too long, reducing their expected
lifetime. If the parameter is 0, the function is disabled.
11.5.1.5.
2007h Fail safe
This object sets the behaviour of the pressure regulator in the event that the cyclic data are no
longer valid (can only be used in node guarding configuration).
Based on the value of this parameter, the pressure regulator can maintain the last valid target
received (0 - Maintenance) or adjust a zero pressure (1 - Discharge).
11.5.1.6.
2008h PID mode
Serves to set the PID gains according to the air volume used. The available values are:
•
0: SET1 (SLOW, suitable for small volumes).
•
1: SET2 (MEDIUM, suitable for medium volumes).
•
2: SET3 (FAST, suitable for big volumes).
•
3: SET4 (CUSTOM).
