19.PARAMETER TABLE
1.3.x.37
Analog output starting time:
It is the time that the analog output remains at the starting value. If the control calculates a demand greater than the starting value, the required value will
be applied.
1.3.x.38
Analog output validation time:
This time is a validation of the need to actuate or shutdown a next ventilation stage and avoid unnecessary fan actuation or shutdown. When reaching
the minimum or maximum value, where the control would immediately shut down or actuate a next fan, the control will wait for this time to validate the
transition and take the next action.
1.3.x.39
Integral time:
When configured, it enables the Proportional / Integral (PI) control of the fans. The value of this parameter corresponds to the time in which 100% of the
control error (hysteresis-setpoint) is accumulated. This value must be configured according to the characteristics of each system. The higher the value,
the slower and more stable the system’s behavior. The lower the configured value, the faster and more oscillatory the behavior is.
1.4
Alarms:
Parameters related to alarm settings.
1.4.1
Alarm settings:
1.4.1.1
Time to validate alarms:
It is the time between the moment when the controller identified and alarm condition and its indication.
1.4.1.2
Time to inhibit alarms:
It is the time when the alarm events are considered after the controller is energized.
1.4.2
Suction alarms:
Alarms are assigned separately for each suction pressure switch. In this list, select the suction to which you want to configure the alarms.
1.4.2.x
Suction alarms:
If configured with the OFF parameter, alarms are not enabled. The letter ‘’x’’ represents suctions 1, 2 and 3.
1.4.2.x.1
Low pressure:
Enables the alarm when the pressure is lower than the configured value.
1.4.2.x.2
High pressure:
Enables the alarm when the pressure is higher than the configured value.
1.4.2.x.3
Hysteresis of pressure alarms:
It is pressure difference to get out of the alarm situation.
1.4.2.x.4
Critical overheating:
Enables the alarm when the temperature is lower than the configured value. This value is usually lower than the low overheating value (
1.4.x.5
)
1.4.2.x.5
Low overheating:
Enables the alarm when the temperature is lower than the configured value.
1.4.2.x.6
High overheating:
Enables the alarm when the overheating is higher than the configured value.
