9.9.6 Setpoint values
One of four (switchable) setpoint values is used a a controller setpoint value. For each of these setpoints, certain spe-
cifications can be made here that are of importance, for example, when entering the setpoint value. The setpoint itself
can also be set here.

9.9.7 Ramp function
The ramp function is used for a constant change of setpoint value w, starting from the current ramp value (= actual value
at time t
of the setpoint value change) up to the ramp end value SP (default setpoint value).
0
A tolerance band can be set around the setpoint value curve to monitor the actual value. If the actual value deviates
from the tolerance band, the tolerance band signal is activated.
NOTE!
If the device operates as a program controller, the ramp function is not active.
NOTE!
The ramp function is not active in manual mode. After switching from manual mode to automatic mode, the actual
value is applied as the current ramp value (ramp starts).
