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, maintenance crew, supervisors, etc. according to what func-
tion level you want for each group. Security Level C is not recom-
mended for most users. Gain access to configuration menus using the
following codes.

temperature.
Proportional Band
Temperature range above/below
set point where proportional
control 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
automatically corrects for small
temperature offsets that occur in
proportional control. The higher
the setting, the faster the
correction occurs. A high 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”.
