Rd4 Controller - Binder VDL Series Operating Manual

Locked operation
Provided that the user administration has been activated by the assignment of passwords for the different
authorization types, the controller operation is first locked after turning on the unit, recognizable by the
closed lock icon in the header.
In the locked view the controller provides all display functions. No setting functions are available.
The setpoints are shaded (light grey) in normal display. Changing them by direct entry in the fixed value
operating mode is not possible. The functional icons for setpoint entry and program start in the footer are
without function.
After turning on the unit, user log-in is required to operate the controller (chap. 12.1.2).
Operation without user log-in / without password-protection
If the password function has been deactivated, after turning on the unit without user log-in there are those
controller functions available, which correspond to the highest authorization level without a password
protection. There is no lock icon in the header.
