12.2 Logging On and
Access Levels
An E2 may be programmed with up to 25 different
users. A user basically consists of a username, a password,
and an access level. Whenever a username and password
are entered during login, the E2 searches the user records
for the username and password. If found, the E2 will log
the user in at the access level configured for the user in the
user records.
The access level determines how many of the E2’s fea-
tures the user may use. The E2 uses four access levels, one
being the lowest, and four being the highest. Table 12-1
gives a description of each level and the capabilities they
have access to.
