4.3  Entering a Security Code 
Introduction 
The level of keyboard lockout may be changed in the Set Up mode. However, knowledge 
of a security code number (0 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. 
Procedure 
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, that selected number must be 
used to change the lockout level from something other than NONE. 
 ATTENTION   Write the number on the Configuration Record Sheet in the configuration 
section so you will have a permanent record.
