Set SIL2 Settings
Advanced Setup
Set SIL2 Settings
Use this screen to set SIL2 settings, which include:
SIL2 Configuration - Use the pulldown to select whether the device is a SIL2 device or
not.
Fault Timeout - There are three SIL2-related faults:
Output is out of range - output exceeds -200% to 105%.
Position out of Range - level sensor fault.
Loop Current Error - mismatch between commanded and read loop output.
Diagnosed only in Normal mode.
Each of these are a failsafe producing fault. To avoid a false failsafe, you can use the Fault
Timeout field to enter a time (in 10 second increments) during which a fault is not reported.
For example, a setting of two sets a timeout of 20 seconds.
NOTE The SIL2 feature (see fields in red box) is available using
firmware 1.1.2 or later.
