4. CONFIGURATION
4.20.5. rES.t - Defining the timer reset command logic
Acronym Scrolling message Submenu Attributes
rES.t LOGIC TYPE OF TIMER RESET TIMER R W
The parameter shows and sets the type of logic used to command the timer reset.
With positive logic, the timer is reset with “object” active.
With negative logic, the timer is reset with “object” inactive.
Unit of measurement: -
Options: POSIT = Positive logic
NEGAT = Negative logic
4.20.6. BAND - Band for timer count
Acronym Scrolling message Submenu Attributes
BAND SYMM SP BAND WHERE TIMER IS ACTIVE TIMER R W
The parameter shows and sets the symmetrical band around the setpoint within which the timer count is on.
The parameter appears if the parameter F.tiM = STABL
If the parameter equals “0.0” the count is immediate as soon as the setpoint is reached for the first time.
Unit of measurement: % of full scale of main input
Options: 0.0...25.0
4.20.7. End - Selecting the function activated at end of count
Acronym Scrolling message Submenu Attributes
End FUNCTION WHERE TIMER IS OVER TIMER R W
The parameter shows and sets the function that is activated when the timer ends the count.
The parameter appears if the parameter F.tiM = ST.STP or STABL.
Unit of measurement: -
Options: NONE = None: control continues with actual setpoint
OFF = Software off
if the Multiset function is enabled:
SP1-2 = Change setpoint SP1/SP2
4.20.8. TIMER - Timer value
Acronym Scrolling message Submenu Attributes
TIMER ACTUAL TIME TIMER R W
The parameter shows and sets the timer value.
Unit of measurement: Minutes or Seconds according to the selection set in the MODE submenu, parameter tMEr
Options: 0...9999
