TEMP Scrollback Display Items
The TEMP scrollback display contains a lot of information
that may appear confusing at first. After entering the TEMP
display (“001RT 43.8F” appears in display), imagine that the
data is stored in a table. The first column identifies the number
of the Log entry (001, 002, etc.) and the return temperature
entry. Each additional column identifies information about
another sensor or the time of the event.
The TEMP scrollback display shows the following
acronyms and information:
RT Return Air Sensor Temperature
ST Supply Air Sensor Temperature
SP Setpoint Temperature
AT Ambient Sensor Temperature
U1 Spare 1 (USDA 1) Sensor Temperature
U2 Spare 2 (USDA 2) Sensor Temperature
U3 Spare 3 (USDA 3) Sensor Temperature
HM Humidity (%)
PP Pulp Probe Sensor Temperature
YR Year
MO Month
DY Day
TI Time
When viewing information in the TEMP or PTI scrollback
display, the status indicator LEDs on the controller show the
unit operating states that were active (ON) when the data or
event was recorded. If the Alarm LED is ON, press the
ALARM key to view alarm and/or event information in the
right display (e.g. “03.204”).
If more than one alarm/event is recorded, press the
DOWN key to scroll to the next alarm/event code. Alarms are
identified by the 2 digits furthest to the right of the decimal
point and are always preceded by a “0” (see the Alarm Code
list on page 4-7). Events (e.g. Power Up) are identified by a 3
digit number that always begins with a “2”.
NOTE; The scrollback alarm/event screen display
does NOT identify which alarms are pretrip alarms.
The 3 digit event codes that may appear in the scrollback
alarm/event screen display includes:
