5.3.3 Device restart and testing of current output 1
• Part 1 - Device restart
• Part 2 - Testing of current output 1
Preparation
Byassing of safety function of process control system, to prevent accidental activation of the
safety function.
‣
Deactivate the locked SIL mode →  25.
Test sequence - Part 1: Device restart
The device restart resets every parameter whose data are in the volatile memory (RAM) to the
factory setting (e.g. measured value data). The device configuration remains unchanged.
The device can be restarted using one of the following methods:
• Disconnecting and reconnecting the terminal voltage.
• Selecting the Restart device option in the Device reset parameter.
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.
Evaluating the results - Part 1: 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 if a diagnostic message is displayed, refer to
the section on "Diagnostics and troubleshooting" in the Operating Instructions for the
device.
Test step - Part 2 - Testing of current output 1
The Simulation submenu (→  29) (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 (→  31) and
the Value current output parameter (→  32), as these are the only parameters
approved for testing the safety-related characteristics.
1. In the Value current output parameter (→  32), select the defined default values
one after the other.
