4.1 Initial Set-Up
Upon initial power-up, the CM-2201/CM-2202 display will
run self-check, display the software version and then start
the main program.
4.2 Display Modes
This feature
determines what messages and functions are
displayed during normal operations. If set to “normal user” only
basic information i
s displayed. If set to “advanced user” all
controller information is displayed. Each parameter shown in
this manual will list the Display Mode required to view
information and access each function duringprogramming.
4.3 Password Protection
The CM-2201/CM-2202 may have password protection enabled
to ensure that sensitive operating parameters are not
inadvertently adjusted. If password protection is enabled,
the user will be prompted to enter a valid value to access any
protected features. The user may also replace the default
password value (1234) with their own unique value for greater
protection of operational parameters.
4.4 Security Levels
CM-2201/CM-2202 has two levels of security. The high level
(Advanced Display) requires password protection. Disabling
the password from the Password Enable/Disable menu will keep
the password disabled indefinitely – any parameter can be
changed without the use of a password. At this level all the
functions and monitoring parameters are open. The low
level (Normal Level) does not give access to parameters
settings, but is open for few parameters monitoring like
temperature, current, GFI, etc.
If the password is “Enabled”, when going directly to the
parameter to be changed, after the ‘up’ or ‘down’ arrow is
pressed, the controller will ask for the password. Then the
parameter can be changed and saved. The password will stay
disabled for 15 min, then be automatically re-enabled. During
the 15 min period when the password is disabled, other
parameters can be changed and saved.
