Availability of the SIL mode function
NOTICE
The SIL confirmation sequence is only visible on the local display and in the operating
tools for devices with the order code for "Additional approval", option LA "SIL".
‣
For this reason, the SIL mode can also only be activated on these measuring devices.
‣
If the LA "SIL" option was ordered for the flowmeter ex works, this option is available when
the measuring device is delivered to the customer. Access is via the operating interfaces of
the measuring device.
‣
If the order option cannot be accessed in the measuring device, the function cannot be
retrofitted during the life cycle of the device. If you have any questions please contact your
Hauser service or sales organization.
Ways to check function availability in the measuring device:

Overview of the SIL mode
The SIL mode enables the following steps:
1. Makes sure that the preconditions are met.
 The measuring device checks whether the user has correctly configured a
predefined set of parameters for the safety function.
If the result is positive, the device continues with the activation of the SIL mode.
If the result is negative, the sequence is not permitted or is aborted, and the device
does not continue with the activation of the SIL mode.
2. Automatically switches a predefined set of parameters to the default values specified by
the manufacturer.
 This parameter set ensures that the flowmeter works in the safety mode.
3. Guides the user through the preconfigured parameters for checking.
 This ensures that the user actively checks all the important pre-settings.
4. Activates write protection for all the relevant parameters in the SIL mode.
All this ensures that the parameter settings that are required for the safety function are
configured correctly. (These settings cannot be circumvented either deliberately or by
accident.)
6.2.2 Locking a SIL device
When locking a SIL device, all safety-related parameter settings are shown to the operator
individually and must be confirmed explicitly. Parameter settings not permitted in the locked
SIL mode are reset to their default values where necessary. A SIL locking code is then entered
