4.14.29. GRAD.D - Gradiente di setpoint in decremento
Acronym Scrolling message Submenu Attributes
GRAD.D PID.1 (or PID.2) SETPOINT GRADIENT IN DECREMENT PID R W
The parameter shows and sets the gradient used when the setpoint value is decreased.
If the parameter is “0.0” the gradient is disabled.
Unit of measurement: digit/second or digit/minute, depending on unit parameter setting
Options: 0.0...999.9
4.14.30. UNIT - Unit of measurement of gradient
Acronym Scrolling message Submenu Attributes
Unit PID.1 (or PID.2) GRADIENT UNIT OF MEASURE PID R W
The parameter shows and sets the unit of measurement of gradient GRAD.I and GRAD.D.
The parameter appears only if GRAD.I or GRAD.D are greater than “0.0”.
Unit of measurement: -
Options: DIG/S = Digit/second
DIG/M = Digit/minute
4.14.31. GRAD.O - Gradient of control output
Acronym Scrolling message Submenu Attributes
GRAD.O PID.1 (or PID.2) CONTROL OUTPUT GRADIENT PID R W
The parameter shows and sets the gradient used by the control output.
The gradient is used to limit rapid changes in the control output.
If the parameter is “0.0” the gradient is disabled.
Unit of measurement: % / second
Options: 0.0...100.0
4.14.32. LBA.TM - Tripping delay
Acronym Scrolling message Submenu Attributes
LBA.TM PID.1 (or PID.2) WAITING TIME FOR LBA ALARM TRIP PID R W
The parameter shows and sets the delay time for tripping of the LBA alarm.
If the parameter is “0.0” the LBA alarm is disabled.
When the LBA alarm is active, it is automatically cancelled if the PV rises (in heating) or lowers (in cooling), or by setting
the parameter AL.ACK = On on the user configuration menu or by switching to Manual mode.
This parameter will not appear in the presence of ON-OFF control (of heating, cooling and heating, and
heating/cooling).
Unit of measurement: Minutes
Options: 0.0...500.0
4.14.33. LBA.PW - Power delivered when LBA alarm trips
Acronym Scrolling message Submenu Attributes
LBA.PW PID.1 (or PID.2) POWER LIMITS BY LBA ALARM CONDITION PID R W
The parameter shows and sets the power value delivered when the LBA alarm trips.
This parameter will not appear in the presence of ON-OFF control (of heating, cooling and heating, and heating/cooling).
In the presence of PID control with ON-OFF heating or cooling, power . may be set for the PID part only
Unit of measurement: %
Options: -100.0...100.0
