Changing A Value; Controller Displays - Thermo Scientific ULT-80 Installation & Operation Manual

The REMOTE indicator illuminates whenever the circulator is configured to
accept a remote setpoint. The controller's SENSOR indicator illuminates
whenever the external sensor is selected. See Controller Displays on the next
page.
NEXT ENTER
Use this key to scroll forward through the menus and also to accept and save
changes.
YES,
This dual purpose key is used to answer yes to YES/NO questions or to
increment numerical values upward for setting numeric values.
NO,
This dual purpose key is used to answer no to YES/NO 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.

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.
When the controller is first powered up it performs a quick self-test then
enters the Operator's Loop. The Operator's Loop displays the bath tempera-
ture and is used to change the setpoint, see Figure 1 on next page. The Setup
Loop can be accessed from the Operator's Loop by pressing and holding the
key combinations shown on Figure 1. The Setup Loop is used to adjust the
controller's PID parameters, select the internal or external sensor, select a
remote setpoint source, and set the high/low temperature limits. It is also used
to select and configure RS-232 operation. See Figure 2 on pages 13-14.
