6.1 Password Protection
The TCM2 module features password protection for settings. The user has the
option to set a four-digit numerical password which must be entered in order to
authorize changes to any set-point or setting. Without the password, all setting
and set-points may be viewed, alarms/trips may be acknowledged and circuits
may be reset but no settings or set-points may be modified. When the correct
password is entered, the TCM2 enters Program Mode where changes are
authorized for 30 minutes. After the 30 minutes has passed, the password will
again be required. The default password is 0000.

PASSWORD SETTINGS. Change PASSWORD from OFF to ON and enter a
password using
