Configuring the MCT-MC - 35 - FDC MCT-MC
4.3.30 Setpoint at End of Automatic Program
The Setpoint at End of Automatic Program entry is used to select the set point that will be used by the loop
control at the end of a program. The end set point selections are mutually exclusive, i.e., selecting one will turn
off the other. Once the desired end set point has been selected, press the “Done” button to return to the main
Loop Configuration screen.
IMPORTANT: If the MC control type is set for Dual Loop, Dual Loop + Cascade or Triple loop operation, both
loop 1 and loop 2 must be set to the same selection so that both loop controls end the program
in the same manner or a program run error will occur. When the final set point is used, the
program remains in operation on the end step with the final set point value while the program
ends and the unit returns to static set point operation. If one loop ends while the other remains
running in the end step, the automatic program run error will occur.
The
Final setpoint of automatic program selection will use the final set point value programmed on the end
step of the program as the control set point when the program reaches the end step. All events will be turned
off and the program will remain in this condition until stopped by the user. Once the program is stopped by the
user, the control set point and manual events will return to the previous static set point and event activation that
were used prior to the program being started.
The
Current control setpoint selection will return the control set point and event status to the previous static
set point and event selections that were used prior to program operation once the program reaches the end
step.
NOTE: The MC does not support the P41/B42 “all outputs off” end of program function”. This selection is not
available through the MC configuration.
4.3.31 Power Fail Recovery
The Power Fail Recovery entry is used to select the desired mode of operation of the loop control when power
is restored if an automatic ramp/soak program was running at the time power was lost. The recovery selections
are mutually exclusive, i.e., selecting one will turn off the others. Once the desired recovery mode has been
selected, press the “Done” button to set the power recovery mode for the loop control board and return to the
main Loop Configuration screen.
For additional information regarding the manner in which program recovery is achieved, see the Appendix
section A.3 Power Recovery Detail.
