3.2.3 Ramp function/firing curve (rAFC)
The device can be operated as a fixed value controller with and without ramp function. In addi-
tion, a firing curve is supported.

3.2.4 Limit value monitoring (Li1, Li2)
The device is equipped with two functions for limit value monitoring (Li 1, Li 2) each with eight
different alarm functions (AF1 to AF8). The two output signals are available for binary functions.

1 AF1: Limit value above and below the setpoint (monitoring
range); symmetric or asymmetric
2 AF2: As AF1, output signal inverted
3 AF3: Limit value below the setpoint
4 AF4: As AF3, output signal inverted
5 AF5: Limit value above the setpoint
6 AF6: As AF5, output signal inverted
7 AF7: Fixed limit value (setpoint independent)
8 AF8: As AF7, output signal inverted
