User Access Codes
The relay includes three levels of access codes. De

pending on their assigned code, users have varying
levels of access to the installed functions.
1.
Level 1 Access
= Read setpoints, moni-
tor status, view status history.
2.
Level 2 Access
= All of level 1 privileges,
plus read & change setpoints, target
history, set time clock.
3.
Level 3 Access
= All of level 2 privileges,
plus access to all configuration functions
and settings.
Each access code is a user-defined one- to four-
digit number. Access codes can only be altered by
a level 3 user.
If the level 3 access code is set to 9999, the access
code feature is disabled. When access codes are
disabled, the access screens are bypassed, and all
users have full access to all the relay menus. The
device is shipped from the factory with the access
code feature disabled.
