Security Codes and Levels
To limit access to the user configuration interface,
security codes are assigned to different menu levels.
Make security codes available to operators, mainte-
nance crew, supervisors, etc. according to what func-
tion level you want for each group. Security Level C
is not recommended for most users. Gain access to
configuration menus using the following codes.
Configuration Menus
The following configuration menus can be accessed through the user interface (see Configuration, page 12).

Process Variable Display Displays the actual
Proc
process temperature.
Process Set Point Adjust Adjusts the target
SP
process temperature.
Proportional Band Temperature range above/
below set point where proportional control
Pb
is active. Most applications require a band
between 10 to 200°F. This menu is active only
when the dip switch is set to "PI"
Automatic Reset Control feature that automati-
cally corrects for small temperature offsets that
occur in proportional control. The higher the
setting, the faster the correction occurs. A high
ArSt
setting could cause overshoot during start-up.
A low setting will not allow process temperature
to reach to set point quickly enough. A setting
of "0" turns off automatic reset. This menu is
active only when the dip switch is set to "PI".
Cycle Time The time for the output to com-
plete ON to OFF to ON cycle. Used only with
proportional control. A fast cycle time provides
better control, but can cause premature wear
CYCL
to contactor or other power switching devices.
Magnetic contactors should not be switched at
less than a 30 second cycle time. This menu is
active when the dip switch is set to "PI".
On/Off Dead Band The range above/below set
point in which no control action takes place.
Determines at what temperature the output
db
switches ON and OFF. For a 5°F dead band,
2.5°F is above and below the set point. This
menu is active when the dip switch is set to
"ONOF".
