Ramp function: automatic re-start of ramp
Programmer
Start: 24 V at
control input W/W2.
W2 is lit.
Cancellation: 0 V at
control input W/W2.
+After start, the actual process value is used as start value for program.
+The 1st program ramp follows the above given equation and start behaviour.
+With running program InL and InH cannot be changed.
+If SP2 is switched off (key D, display '----'), the programmer is off.

Ramp function, gradient and start-up circuit are shown on the following page.
Pressing keys I and D changes the value (the longer the faster).
When pressing M the change is effective and Con4 is displayed.

changes via keys are disabled
Process value X
X < SP2 The effective set-point runs from X to SP2 with positive ramp
X > SP2 Start at SP2
X < SP2 Start at SP2
X > SP2 The effective set-point runs from X to SP2 with negative ramp
