DispPass provides the
ability to make changes to program parameters (i.e. the SetPeriod parameter of the
SpeedDetect FB). A non-authorized user will be able to navigate the display screen from field
to field, but will not be able to make changes without, first, entering the appropriate password.
There are three passwords that can be set from the front panel or the VLS software. Each
password can control access to many different displayed parameters.
The security level for a displayed parameter must be assigned with the VLS software but, the
actual password can be set, changed or removed with the front panel keys. The following is the
step-by-step process for modifying password settings.

1 ) From the TopMenu, scroll to "Others..." and press the "OK" key.
2 ) From the options that appear, scroll to "DispPass" and press the "OK" key.

4 ) Enter the Password with the +, - and directional buttons.
