3.12 Setpoint ramp SP.r
SP.r
Defines the ramp of the setpoint SP via time
(gradient)
Setting range: 0 to scope of the measuring range in
PV/minutes or hours
(see below 3.13 rA.d); PV [phys. unit]
e.g. K/min or hour (at dP = 0)
Setting SP.r = 0: no setpoint ramp.
Start value of the setpoint ramp is always the current
value of the process variable PV (a).
The current setpoint is displayed.
3.12 Setpoint ramp SP.r
The setpoint ramp is triggered after:
- switching on the device or after a power failure
- sensor failure
- any setpoint change
- switching over to the second setpoint SP.2
- a control function STOP, CLOSE, OPEN (via digital input)
- switching from manual mode to automatic mode
3.13 Ramp direction
rA.d
Setting the direction of effect and time behaviour of the setpoint ramp SP.r (if SP.r > 0, see also 3.12 SP.r)
Selection:
0 Ramp with SP.r as *physical unit/min, at falling and rising setpoint changes.
1 Ramp with SP.r as *physical unit/min, only at rising setpoint changes.
2 Ramp with SP.r as *physical unit/min, only at falling setpoint changes.
3 Ramp is deactivated (similar to setting SP.r = 0 ).
4 Ramp with SP.r as *physical unit/hour, at falling and rising setpoint changes.
5 Ramp with SP.r as *physical unit/hour, only at rising setpoint changes.
6 Ramp with SP.r as *physical unit/hour, only at falling setpoint changes.
* physical unit see 3.9 adjusting dI.L, dI.H
