14.7 Predefined fault inputs
Function block "Boiler" and the pump blocks provide predefined fault inputs.
For a description of these fault inputs, refer to the relevant function blocks. These fault
inputs are also parameterized at the relevant function blocks.
14.8 Fault inputs
14.8.1 Universal fault inputs
The RMH760B has 4 universal fault inputs. These can be activated via "Extra
configuration".
Either analog or digital inputs can be defined as fault inputs. If the input is not
assigned to an input that has already been configured, the input identifier and thus
the type of input or the unit can be freely selected.
