Alarm is occurring when it should
not.
Alarm output indication is incor-
rect.
Alarm is not occurring when it
should.
Output cycles (turns on and off)
too frequently.
Controller does not control close
enough to the set point.
Controller's process value reading
is decreasing but actual process is
increasing.
Parameter(s) do not appear.
Cannot access Operation Page.
Cannot change the set point.
Profile will not start or resume.
Lower display flashes between
static set point value and File
Number / Step Number. For
example, if File 1, Step 1 is not
valid, the display will flash 1.1.
Profile takes more time to com-
plete than what is programmed.

Troubleshooting
Probable Cause
The process value is beyond an alarm set
,
point.
Alarm settings are incorrect.
Input may be in an error condition.
Alarm may be latched.
Alarm settings are incorrect.
Alarm may be silenced.
Alarm settings are incorrect.
Wrong control mode. PID control selected in-
stead of On-Off control.
The cycle time is not set properly.
Wrong control mode. On-Off control selected
instead of PID.
PID is not tuned properly.
Thermocouple polarity is reversed.
Analog voltage or analog current input scal-
ing is reversed or incorrect.
Parameter is not active.
Parameter lockout is active.
Operations Page is not configured properly.
Parameter lockout is active.
Profile step has target set point or Wait-for
Process values that are outside of
values.

Jump Loop step is trying to jump to itself.
Guaranteed Soak Deviation is enabled. The
program will stop the count down time until
the process value returns to within the de-
viation window. The

Determine when alarms messages will dis-
play and the proper response to an alarm
message.
Adjust the alarm settings to be correct for
the application.
See error messages.
Press the Infinity Key
alarm.
Adjust the alarm settings to be correct for
the application.
See the Features chapter for information on
alarm silencing.
Adjust the alarm settings to be correct for
the application.
Select On-Off control mode (
[CL; m ]
hysteresis value.
Adjust the cycle time.
Select PID control and perform tuning.
Run autotune or perform manual tuning.
Check thermocouple connections. All thermo-
couple connections, including thermocouple
extension wire, must maintain the correct
polarity for proper operation.
Check the settings of the analog output scale
low and scale high parameter (Setup Page).
See Setup and Operation chapters to deter-
mine when parameters should appear.
Set the correct level of lockout for access
(Setup Page).
Select the desired parameters for the Pro-
gramming Page.
Set the correct level of lockout for access
(Setup Page).
Keep target set point or Wait-for Process val-
or
ues inside set point limits or adjust set point
[SP; l o]
limits.
Correct Jump Loop step (cannot jump to
itself).

required, set
If Guaranteed Soak Deviation function is

required, increase
amount of time the process is outside of the
