Setup Loop
The Setup Loop is used to adjust the controller's PID parameters, select the
internal (1) or remote (2) sensor, and set the high/low temperature limits, and
to select RS232 operation.
Enter the Setup Loop from the Operator's Loop by pressing and holding the
NO key, then press the NEXT ENTER key. Use the YES/NO keys to adjust
the values. Press the NEXT ENTER key twice to accept the new value.
While in the Setup Loop, if any key is not pressed during a one minute time
span, the controller will automatically return to the Operator's Loop tempera-
ture display.
NOTE: If the unit exceeds either temperature limit, the appropriate error
message will flash, see page 15. The unit will not shut down (unless the
temperature exceeds the high temperature cutout setting, see page 17).
