Displays
This section discusses the controller’s main displays: bar
graph, single loop and job.
Bar Graph Display
On power up, the controller displays general symbolic in-
formation for up to eight loops. This screen is called the bar
graph display. The diagram below shows the symbols used
in the bar graph display.
Figure 3.3 Bar Graph Display
Table 3.1 explains the symbols you see on the top line of
the bar graph display. These symbols appear when the con-
troller is in dual output mode (heat and cool outputs en-
abled) and single output mode (heat or cool outputs
enabled, but not both).

Symbol Description
<
Loop is in low process or low deviation alarm.
>
Loop is in high process or high deviation alarm.
Loop is above setpoint. If you enable the high
or low deviation alarm, this symbol is scaled to
it. If you do not enable these alarms, these
symbols are scaled to the setpoint +5% of the
sensor’s range.
Loop is at setpoint. If you enable the high or
low deviation alarm, this symbol is scaled to it.
If you do not enable these alarms, these sym-
bols are scaled to the setpoint +5% of the sen-
sor’s range.
Loop is below setpoint. If you enable the high
or low deviation alarm, this symbol is scaled to
it. If you do not enable these alarms, these
symbols are scaled to the setpoint +5% of the
sensor’s range.
(blank)
Loop’s input type is set to SKIP.
F
Open thermocouple (T/C), shorted T/C,
reversed T/C, open RTD or shorted RTD.
