3.14 TUNING
A series of tuning displays can be accessed directly from the runtime displays. These
displays provide for tuning of both alarm and control parameters. Progression through the
tuning displays, and tuning of parameter values is done using the front panel keys. Specific
parameters available for tuning depend on the configuration of the template identified by the
loop tag. Access to tuning adjustments can be password protected.
3.14.1 Password
When a tune password is configured, the assigned password number must be entered in
order to make tuning adjustments. A single password permits access to both alarm and
control tuning adjustments. If the requested password is not entered or the entered password
is not correct, the tuning parameters and their current values can be viewed but the values
cannot be changed.
The password access can be configured to timeout after an elapsed time of 1 to 54 minute s.
After initial entry of the password, you can exit the tune sequence and reenter without using
the password until the end of the timeout period. If the timeout occurs during a tuning
operation, the sequence can be completed. Reentry will again require the password. If the
timeout is set to 0, the timeout period is infinite. In this case the password is required for initial
entry to the tune sequence and is never used again.
