Wait in a Guaranteed Soak
During a guaranteed soak in a recipe the timer will continue to count down while the PV value is within the
wait limit band. If the value of the PV moves outside of this range, the timer will pause until the PV value
falls back within the wait limit band.
If the PV value moves outside of the wait limit band, the recipe will pause and a new timer will begin. This
timer is called the Default Hold Time and can be found and adjusted in the Menu under Furnace Setup.
This timer will keep track of the amount of time the PV value has been outside of the wait limit. If the PV
value fails to move back into the wait limit band within the Default Hold Time, the programmer alarm will
be activated. Once the PV value moves back within the wait limit band, the soak timer will resume.
For example, if the PV is temperature with a set point of 1500° and the wait limit is 15°, the recipe timer will
run only while the temperature is 1485°-1515°. If the PV moves outside of this range, the recipe timer will
pause and the Default Hold Time countdown will begin. The recipe timer will resume once the PV moves
back into the range of 1485°-1515°.
