3–7 Dwell Timer
Alarm 1 or alarm 2 can be configured as dwell timer by selecting 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 hid-
den.
The case is the same for alarm 2.
If alarm 1 is configured as dwell timer, A1SP, A1DV, A1HY and A1MD are hidden.
