Timer Start Threshold
A single threshold value is available to provide a holdback on the entry to the dwell part of
the ramp/dwell pair. It holds back the dwell until the PV has reached the band defined by
+/- threshold around the PV. The timer starts timing when the temperature is within this
threshold of the setpoint. This provides a guaranteed soak temperature. The threshold
can be set to Off (0) in which the threshold is ignored and the timing starts immediately.
Note that if a ramp rate is set, the ramp completes before timing starts.
To set the threshold value, press SCROLL
button until ‘THRES’ is displayed.
(“THRES”
can be accessed from Level 1 and Level 2). Press UP
or DOWN
button to adjust the value (In the example given below, the dwell periods will not start until
the PV is within 5 units of the set point)
.
Timer as 8-Segment Programmer
A sample program profile of 3216c is shown in the diagram below. It is an 8 segment
programmer consisting of four ramp/dwell pairs. Each ramp consists of a controlled rate
of change of set point to a target level. Each ramp is followed by a dwell at that level. The
ramp rate, target level and dwell time are set by the user.
