To access or modify the security parameters through the front panel display, a password
always needs to be entered before a lock can be enabled or disabled or the password
modified. Note, that as the password can be read over the network, any security password
can always be over written if the local operator enters an incorrect password.
The changes to the calibration and read only security features are updated when you exit
the security submenu and return to the configuration menu; while changes to the display,
keypad, or configuration security settings are updated when the operator exits the
configuration menu.
The factory default for the security menu is to disable all lock modes and to preset each of
the security passwords to 1234.
The Display Lock
This security setting blanks the front screen so the current weight reading on the scale
cannot be observed; and while the display is locked the Mode, Zero, Tare, and
Configuration buttons are disabled regardless of the keypad lock or configuration lock
settings; as enabling these buttons without the operator being able to read the front panel
display would lead to process errors.
If the ENTER button is pressed the “Enter Password” page will appear on the display. At
this level of security the operator can enter one of three possible passwords for the display
lock, the keypad lock, or the configuration lock.
The display lock flowchart below shows the options and features when the display lock is
enabled.
