The value saved is indicated on the fourth line of the local display.
Options:
• Valid: Select this option if the entered value or the desired value is displayed. The device
continues to interrogate the safety-related parameters.
• Not valid: Select this option if an incorrect value or a value that was not entered is
displayed. In this case, operation in the safe measuring mode is not possible. The
SAFETY LOCK parameter displays the status "Unlocked". The confirmation sequence is
cancelled.
15. Once the safety-related parameters have been successfully interrogated, the
password "7452" must be entered again via the CONF. PASSWORD parameter.
Afterwards, the device is locked for the safe measuring mode. The SAFETY LOCK
parameter displays the status "Locked". This locking has the highest priority and can
only be disabled via the SAFETY LOCK and SAFETY PASSWORD parameters.
16. Switch the device off and then on again. This ensures that the parameter settings for
the current output, alarm response and locking are saved. Read out the parameters
again and compare them to the data recorded in the "Device parameter configuration
report".
The "Offline" operating function is not permitted for the configuration of an
application with functional safety. Please ensure that no messages (e.g. Device
disconnected) are displayed during the parameter configuration.
Parameter configuration via FieldCare operating program
1. The connection can be established in the following two ways: 1) Select the "HART
Communication" connection wizard. The device will then be found automatically and
opened online. Ensure that the device bus address = 0. 2) In the tree structure, select
"Create projects" → "Add device" → "HART communication" and then select "Create
network". The device is opened online. Ensure that the device bus address = 0.
2. Ensure that the connection has been made with the correct device. This can be done
using the "Measuring point" parameter, the extended order number or the serial
number.
3. Reset parameters to factory setting: reset code "7864" (see the associated Operating
Instructions, "Resetting to factory setting (reset)" section). Check default values,
number formats and parameter descriptions with the "Device parameter
configuration report".
