for dwell time adjustment. The dwell time is measured in minute
ranging from 0.1 to 4553.6 minutes. Once the process reaches the set
point the dwell timer starts to count down until zero ( time out ). The
timer relay will remain unchanged until time out. The dwell timer
operation is shown as following diagram.
After time out the dwell timer will be restarted by pressing the RESET
key.
The timer stops to count during the manual control mode, failure
