1. Make sure that no undesired switching operations are triggered!
 The function test must take place when the device condition is OK: MAX safety
and sensor uncovered or MIN safety and sensor covered.
2. Press the operating key for the proof test on the electronic insert for at least 3 s.
 The device function check is performed.
The output changes from the OK state to the demand state.
3. Release the operating key.
 If the internal test is passed, the device switches back to normal operation.
Duration of the function check: at least 10 s or if the key is pressed for longer than 10 s,
the check lasts until the key is released.
If the housing may not be opened during operation due to explosion protection
requirements, e.g. Ex d /XP, the function test can also be started via the digital
communication interfaces (HART, CDI, Bluetooth) with the aid of the appropriate
operating tool (FieldCare, DeviceCare, SmartBlue, AMS, PDM, etc.).
7.4 Structure and function of the operating menu
The differences between the structure of the operating menus of the local display and the
Hauser FieldCare or DeviceCare operating tools can be summarized as follows:
The local display is suitable for configuring simple applications.
The operating tools (FieldCare, DeviceCare, SmartBlue, AMS, PDM, ...) can be used to
configure the parameters of wide-ranging applications.
Wizards help the user to commission the various applications. The user is guided through
the individual configuration steps.
7.4.1 User roles and related access authorization
The two user roles Operator and Maintenance (as-delivered state) have different write
access to the parameters if a device-specific access code has been defined. This access code
protects the device configuration from unauthorized access.
If an incorrect access code is entered, the user obtains the access rights of the
Operator
role.
