4.8.6. RAMP.T - Step time ramp
Acronym Scrolling message Submenu Attributes
RAMP.T PR.STP.1 (o PR.STP.2…PR.STP.192) RAMP TIME se modalità“Programmatore
semplificato”disattiva; o PR.STP.1…PR.STP.16 RAMP TIME se modalità“Prog-
rammatore semplificato”attiva.
PR.STP R W
The parameter shows and sets the time taken to go from the previous setpoint to the setpoint of the current programming
step.
Unit of measurement: hh.mm or mm.ss (hours.minutes or minutes.seconds). Depends on time base set with
submenu MODE, parameter t.Pro
Options: 00.00...99.59
4.8.7. HOLD.T - Hold time in step
Acronym Scrolling message Submenu Attributes
HOLD.T PR.STP.1 (o PR.STP.2…PR.STP.192) HOLD TIME se modalità“Programmatore
semplificato”disattiva; o PR.STP.1…PR.STP.16 HOLD TIME se modalità“Prog-
rammatore semplificato”attiva.
PR.STP R W
The parameter shows and sets the time the program waits before going to the next step.
Unit of measurement: hh.mm or mm.ss (ore.minuti o minuti.secondi). Depends on time base set with submenu MODE,
parameter t.Pro
Options: 00.00...99.59
4.8.8. HBB - Enable Hold Back Band function
Acronym Scrolling message Submenu Attributes
HBB PR.STP.1 (o PR.STP.2…PR.STP.192) HOLD BACK BAND FUNCTION se mo-
dalità“Programmatore semplificato”disattiva; o PR.STP.1…PR.STP.16 HOLD
BACK BAND FUNCTION se modalità“Programmatore semplificato”attiva.
PR.STP R W
The parameter enables and disables the Hold Back Band function
The HBB function checks that the variable remains in the required tolerance interval. If the maximum deviation is excee-
ded, the program time base is stopped. The function is settable independently for each programming step. In addition, it
can be enabled for the time ramp only, for the hold time only, or for both.
Unit of measurement: -
Options: OFF = Disables HBB function
On = Enables HBB function (band symmetrical to SP)
On.P = Enables HBB function (band positive only with respect to SP)
On.n = Enables HBB function (band negative only with respect to SP)
4.8.9. BAND - Maximum deviation for HBB
Acronym Scrolling message Submenu Attributes
BAND PR.STP.1 (o PR.STP.2…PR.STP.192) HOLD BACK BAND VALUE se moda-
lità“Programmatore semplificato”disattiva; o PR.STP.1…PR.STP.16 HOLD
BACK BAND VALUE se modalità“Programmatore semplificato”attiva.
PR.STP R W
If the HBB function is enabled, the parameter shows and sets the maximum deviation allowed for PV compared to SV.
Unit of measurement: °C, °F, % based on chosen scale
Options: 0...999
