12.9.1 Function and hysteresis
For the AF1 to AF6 alarm functions, the final limit value depends on the setpoint value – the
entered limit value is added to or subtracted from the setpoint value. The AF7 and AF8 alarm
functions work with a fixed limit value which corresponds to the limit value entered. Shown with
the associated hysteresis functions (non-standard left, symmetrically, non-standard right)
