Protection against configuration changes
After configuration, the SIPART PS2 positioner must be switched to automatic operation.
You should then fit the housing cover so that the device is protected against unwanted and
unauthorized changes/operation.
The SIPART PS2 positioner is fitted with an additional protective function to prevent
configuration changes:
1. Configure the parameter 43.BIN1 = bLoc2.
2. Bridge terminals 9 and 10 of the binary input BE1.
In this condition, the "configuration" operating level using the keys and HART
communication and manual operation are blocked.
