Device manual

3.12 Setpoint ramp SP.r

Defines the ramp of the setpoint SP via time (gradient)
Setting range: 0 to scope of the measuring range in
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.
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

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:

SP.r
PV/minutes or hours
(see below 3.13 rA.d); PV [phys. unit]
e.g. K/min or hour (at dP = 0)
rA.d
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.
