3-12 Finishing Setup: Setting Up Passwords
You can establish passwords for two levels of security: operators and supervisors. The
controller comes from the factory with neither password set. This allows every user access to
all functions.
If you choose to establish passwords store them in a secure
location because if they are forgotten there is no way to reset them
without a service call.
Operator Password. If you define a password for operators, then a password will be
required to carry out any function (other than reviewing the status screens). Entering the
operator’s password will give the user access to the setpoints for leaving temperature, high
temperature warning, high temperature fault.
If you choose to define an Operator Password you must also define a
Supervisor Password to complete the security setup.
Supervisor Password. If you define a password for supervisors (or setup personnel) then
most settings can be changed only after entering the password. The password will be
required to display the extended setpoints for operating parameters and alarms. Section 4-6
shows a table of setpoints and the restrictions between Operator and Supervisor.
