NO,
This dual purpose key is used to answer No to Y/N questions or to decrement
numerical values downward for setting numeric values.
Changing a Value
The YES key increments the value. The NO key decrements the value.
The display will flash as soon as either key is depressed, and will continue to
flash until the NEXT ENTER key is pressed twice to accept the new value.
The new value will not be used by the controller until the NEXT ENTER key is
depressed twice and the display stops flashing.
NOTE: If the ENTER key is not depressed twice within 10 seconds, the
controller will time out and the new value will not be accepted. The controller
will revert to the previous setpoint value.
The controller will not allow you to enter a value above the maximum
(+150°C) or below the minimum (-25°C).
Controller Displays
An alphanumeric display presents numeric readings of various operating
conditions within the bath. Display function is selected by pressing the appro-
priate keys to move through a menu of available information.
The controller has several loops. The Operator's Loop displays the bath
temperature and is used to change the setpoint, see page 12. The Setup Loop
is used to adjust the controller's PID parameters, select the internal or remote
sensor, and set the high/low temperature limits. It is also used to select RS232
operation. See page 13-14. The Setup Loop can be accessed from the
Operator's Loop by pressing and holding the key combinations shown on
Figure 1 on the next page.
When the controller is first powered up it enters the Operator's Loop. The
display will indicate the bath temperature.
NOTE: If altering any settings in the various loops, should you desire to return
to the temperature display and abort any changes, keep pressing the NEXT
ENTER until the display reads Stor, then press NO.
