Output 2 can be configured as dwell timer by selecting TIMR for
OUT2. As the dwell timer is configured, the parameter SP2 is used
for dwell time adjustment. The dwell time is measured in minutes
ranging from 0.1 to 4553.6 minutes. Once the process reaches the
setpoint the dwell timer starts to time down to zero ( time out ).
The timer relay will remain unchanged until time out. The dwell
timer operation is shown in the following diagram.
After time out the dwell timer can be restarted by pressing the
RESET key.
The timer stops timing during the manual control mode, failure
mode, calibration period and auto-tuning period.
