7.9.6 Setpoint values
One of four (switchable) setpoint values is used a a controller setpoint value. For each of these setpoints,
certain specifications can be made here that are of importance, for example, when entering the setpoint
value. The setpoint itself can also be set here.
7.9.7 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
0
of the setpoint value change) up to the ramp end value SP (default setpoint
value).
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).
Parameter Selection/text/value Description
Min. limit -1999 to 9999 (0) Minimum admissible setpoint value (lower input
limit)
Max. limit -1999 to 9999 (400) Maximum admissible setpoint value (upper input
limit)
Setpoint value -1999 to 9999 (0) Fixed setpoint value (input limits dependent on
min. limit and max. limit)
Parameter Selection/text/value Description
Function Off Ramp function is not active.
Per minute Ramp function is active.
Unit of ramp slope: Kelvin per minute
Per hour Kelvin per hour
Per day Kelvin per day
Pos. gradient 0 to 999 Value for positive ramp slope
Neg. gradient 0 to 999 Value for negative ramp slope
Tolerance band 0 to 9999 Amount of admissible upward and downward devi-
ation of the actual value (standard tolerance band
around setpoint value)
Stop signal Digital selector
No selection
Signal (high active) for stopping the ramp (setpoint
value remains constant at the current value)
