Figure 3.6 Dwell Timer Function

If alarm is configured as dwell timer, ALHY and ALMD are
hidden.

The a

larm 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 minute

s

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

in the

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 mode,
calibration period and auto-tuning period.
