7.1 Conditions of use
The configuration is protected with a password. For more data on password protection and
device configuration, refer to the “Operation” chapter in the handbook (document [N1]).
7.2 Failure state
For any type of safe or dangerous detected failure, the device sets the current output to less than
3.6 mA. Although this value can also be set to a high error value (≥ 21 mA), some hardware
failures will always cause the device to give a low error value (≤ 3.6 mA). Thus, the output signal
for the fail-safe condition is less than 3.6 mA. For more data, refer to
Limits for supervisor menu
functions related to device configuration on page 17 (2.4.2 RANGE I).
WARNING!
Only approved personnel can change device settings. Keep a report of changes to the device
settings. These reports must include the date, the menu item (e.g. 2.3.1 TANK HEIGHT), the old
parameter and the new parameter.
