150 UDC 3300 Controller Product Manual 4/00
5.3 Entering a Security Code
Introduction
The LOCKOUT feature in the UDC 3300 is used to inhibit changes (via
keyboard) of certain functions or parameters by unauthorized personnel.
There are different levels of LOCKOUT depending on the level of
security required. These levels are:
NONE
CALIB
+CONF
+VIEW
MAX
See Section 4 - Configuration Definitions for details.
Security code numbers
The level of keyboard lockout may be changed in the Set Up mode.
However, knowledge of a security code number (1 to 4095) 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.
Procedure
If you require the use of a security code, select a number from 0001 to
4095 and enter it when the lockout level is configured as NONE.
Thereafter, that selected number must be used to change the lockout level
from something other than NONE.
CAUTION
Write the number on the Configuration Record Sheet in the
configuration section so you will have a permanent record.
Use the procedure in Table 5-3 to enter a security code.
