Security Lockout

Introduction
The LOCKOUT feature in the 7866 Controller inhibits changes to certain functions or parameters by
unauthorized personnel. There are three different lockout levels:
NONE Allows changes to all functions and parameters.
CALIB Calibration group functions are hidden from view.
UNIT
VIEW All parameter values are read only and calibration is not permitted.
To set up a lockout level, refer to Table 5-9. In step 5 change to the desired Lockout phase.
Entering a Security Code
The level of keyboard lockout may be changed in the Set Up mode. However, knowledge of a four-
character security code number [0000 (no security) to 9999] may be required to change from one level of
lockout to another. When a controller leaves the factory it has a security code of 0, which permits changing
from one lockout level to another without entering any other code number.
If you require the use of a security code, select a number from 0001 to 9999 and enter it when the lockout
level is configured as NONE. Thereafter, you will need that selected number to change the lockout level
from something other than NONE.
