Programmer set-up:
For using the controller as a programmer, select parameter
SP.Fn = 1 in the
ConF menu (r page 21). The programmer is started via one of digital inputs
di1..3. Which input shall be used for starting the programmer is determined by
selecting parameter
P.run = 2 / 3 / 4 in the ConF menu accordingly.
(r page 23).
For assigning the program end as a digital signal to one of the relay outputs, para-
meter
P.End = 1 must be selected for the relevant output OUT.1...OUT.3 in the
ConF menu (r page 26, 27).
Programmer parameter setting:
A programmer with 4 segments is available to the user. Determine a segment du-
ration
Pt.01 .. Pt.04 (in minutes) and a segment target set-point SP.01 ..
SP.04 for each segment in the PArA menu (r page 38).
Starting/stopping the programmer:
Starting the programmer is done by a digital signal at input di1..3 selected by pa-
rameter
P.run (r page 23).
The programmer calculates a gradient from segment end setpoint and segment
time. This gradient is always valid. Normaly, the programmer starts the first seg-
ment at process value. Because of this the effective run-time of the first segment
may differ from the at
PArA level setted segment time (process value ¹ set-
point).
After program end, the controller continues controlling with the target set-point
set last.
If the program is stopped during execution (signal at digital input di1..3 is taken
away), the programmer returns to program start and waits for a new start signal.
