• OU : output 1 switches irrespective of a fault as defined by parameters SP1, rP1
und OU1.
4. Select FOU2 from the extended functions menu.
5. Press and hold Set to modify the parameter value.
6. Set the value for output 2.
• On : output 2 switches on in case of a fault, the analog signal goes to the upper
