may be entered via the keypad. The microprocessor al-
ways retains the last entered set points in memory. The
set points will change 1
°
(one full degree)
OR
0.1
°
(one
tenth of a degree - if configured to do so) for each press
and release of the UP ARROW or DOWN ARROW key.
NOTES
The microprocessor may be configured with a
minimum and/or maximum set point other than
the default values listed above. “MAX SET-
POINT HAS BEEN REACHED” or “MIN SET-
POINT HAS BEEN REACHED” will display in
the MessageCenter when either of these condi-
tions is reached.
Set point may be changed any time the Main Power
switch is not in the OFF position, or when the unit is in
PC Mode EXCEPT when:
•
Viewing the Alarm List, Data List or Functional Para-
meters
OR
•
When the unit is in Pretrip
OR
•
When the unit is in Sleep Mode.
Pressing the = key will cause the new displayed set
point value to become active and “SETPOINT
CHANGED” will be displayed. If the new value is not en-
tered, after 5 seconds of no keypad activity, the entire
display and Light Bar will flash and the buzzer will be en-
ergized for 15 seconds (with “SETPOINT NOT
CHANGED” displayed) and then revert back to the last
entered set point. All other keys are active at this time
and if pressed while the display is flashing, will stop the
flashing, and perform the requested function.
TIP
The set point may be changed quickly by press-
ing and holding the UP ARROW or DOWN AR-
ROW key. The longer the key is held, the faster
the setting will change.
