SECURITY LEVELS
The security level feature allows you to limit access to the menus, setpoint, and operating mode selection
according to the needs of your application. The security levels provided are Key Lockout , Setpoint , Setpoint
plus Mode, User, Configuration , and Factory .
To view or change security level from the Process Variable display, press and hold the Menu Access
key for approximately 10 seconds. (Ignore the menu label that will appear in the upper display after
approximately three seconds.) The controller will display

(Access Level) and the current security level
label, e.g.,

. Use the Raise or Lower keys to index through the security levels.
Press the Mode/Enter key once to select the new security level desired and return to the Process Value
display.
The controller’s
initial security level,

When you have
completed configuring
the instrument, we
recommend the
security level be set
to the most restrictive
level suitable for your
application.
NOTE: Removing this jumper on the
microcontroller board disables the keypad,
thus preventing any operator access.
