Status display/PV
: shows the value of PV (Process Variable). When
in programming mode, shows the parameter name.
Parameter display/SV
: shows the SV (

the value of other parameters of the controller.
COM Indicator
: Flashes when communication messages are sent by
the controller.
TUNE Indicator
: Lights during the execution of PID automatic
tunning.
MAN Indicator
: Lights when the controller is in manual.
RUN Indicator
: Lights when the controller is active, with control and
alarm outputs enabled.
OUT Indicator
: For relay or pulse control output, reflects the actual
state of the output. If an analog output is assigned for control, lights
continuously.
