Alarm output can be configured as dwell timer by selecting TIMR
for ALFN . As the dwell timer is configured, the parameter SP3 is
used for dwell time adjustment. The dwell time is measured in
minutes, int the range of 0.1 to 4553.6. Once the process reaches
the set point the dwell timer starts to time down to zero (time
out). The alarm relay will remain off 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 during the manual control mode, failure mode,
