The device can be restarted using one of the following methods:
• Disconnecting and reconnecting the terminal voltage.
• In the Device reset parameter, select the Restart device option.
Setup → Advanced setup → Administration
‣
Restart the device.
NOTICE
Wrong option selected in the "Reset device" parameter.
If the "To factory defaults" or "To delivery settings" option is selected, the device configuration is
reset and the device must be reconfigured!
‣
In the Device reset parameter, select only the Restart device option.
Evaluation of results: Device restart
‣
Test restart of device.
 After a successful startup, the local display switches automatically from the startup
display to the operational display. If the device restarts and no diagnostic message is
displayed, this step has been completed successfully.
If nothing appears on the local display or a diagnostic message is displayed, refer to
the "Diagnostics and troubleshooting" section of the "Operating Instructions" →  10
7.3.2 Test sequence: Testing of current output 1
The Simulation submenu (Diagnostics → Simulation) enables you to simulate, without a real
flow situation, various process variables in the process and the device alarm mode and to
verify downstream signal chains (switching valves or closed-control loops).
Performing the test
For proof testing, use only the Current output simulation parameter (→  34) and the
Value current output parameter (→  34), as these are the only parameters approved
for testing the safety-related characteristics.
1. In the Value current output parameter, select the defined default values one after the
other.
2. Compare current at output 1 with this default value.
Comparing the current values
The current values can be compared using one of the following methods:
• Measure the current of the DUT at the logic subsystem (process control system or safety-
related PLC).
• Measure the current at the DUT using an external, traceably-calibrated ammeter.
‣
Compare the current values.
