4.13 Entering a Security Code
The level of keyboard lockout may be changed in the Set Up mode. However,
knowledge of a security code number (0 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.
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 Appendix C so
you will have a permanent record.
