Menu “03” (Alarm, Timing and Limit Setup)
In this menu, alarms, cycle times, setpoint target time and
limits are established. After changing the access code to “03”,
press the Parameter/Access key to step through the vari-
ous parameters. To set or
change parameter values, follow the instructions given previ-
ously.
Menu “02” (Control Mode)
Gain, Rate and Reset parameters are automatically set during
autotuning. However, they can be manually adjusted by the
operator. To return the controller to the Run mode, change
the menu level access code back to “00” or “01” as previous-
ly shown.
Menu “01” (Run — Limited Access Mode)
The only parameter that can be changed at this menu level is
the Setpoint Value, using the appropriate Raise or Lower
key. To set or change other parameters, the operator
must access another menu level by pressing and holding the
Parameter/Access key for 4 seconds.
Menu “00” (Run — Key Lock Mode)
In this menu, both display windows are illuminated; however,
access is denied to all parameters. To set or change parame-
ters, the operator must access another menu level as
instructed previously.
Because the controller’s
initial configuration
affects other menu
levels, it is important
to set all required para-
meters in this menu first
before accessing other
menu levels.

Menu Level Descriptions
Menu “05” (Configuration Setup)
This is the menu level used for specifying initial configuration
parameters before the controller is placed in Run mode.
After changing the access code to “05” as instructed in the
previous paragraph, press the Parameter/Access key to
step through the various control parameters.
Available parameters will flash in the lower window display,
alternating with the current value for that parameter, each
time the key is pressed. To increase or decrease the
value, simply press the appropriate Raise
or Lower key, then press the key to step to the
next parameter. To exit the menu at
any time, press the Mode key. Note: When program-
ming in menu level “05”, all outputs are disabled; however,
any active alarms will remain active until the alarm condition
is removed. New alarm conditions will not be recognized.
Menu “04” (Communications and Calibration Setup)
This menu is used to set up the controller for digital
communications and for recalibrating the controller when
changing from thermocouple to RTD input, or vice versa. If
your controller was ordered with the digital communications
option, set these parameters next. To access this menu level,
follow the instructions previously given.
