3–7 Dwell Timer
Alarm 1 or alarm 2 can be configured as dwell timer by select-
ing TIMR for A1FN or A2FN, but not both, otherwise Er07
will appear. As the dwell timer is configured, the parameter TIME is used for dwell time
adjustment. The dwell time is measured in minute ranging from 0 to 6553.5 minutes.
Once the process reaches the set point the dwell timer starts to count from zero until time
out.The timer relay will remain unchanged until time out. The dwell timer operation is
shown as following diagram.
If alarm 1 is configured as dwell timer, A1SP, A1DV, A1HY and A1MD are hidden.
The case is the same for alarm 2.
Example:
Set A1FN=TIMR or A2FN=TIMR, but not both.
Adjust TIME in minutes
A1MD (if A1FN=TIMR) or A2MD (if A2FN=TIMR) is ignored in this case.
