Programmer set-up:

For using the controller as a programmer, select parameter Cntr /SP.Fn = 1 in

the ConF menu. The programmer is started via one of digital inputs di1..3 or the

è key. Which input shall be used for starting the programmer is determined by

selecting parameter LOGI/P.run = 2 / 3 / 4 / 5 in the ConF menu according

ly. For assigning the program end as a digital signal to one of the relay outputs,

parameter P.End = 1 must be selected for the relevant output OUT.1...OUT.3 in

the ConF menu.

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.

Starting/stopping the programmer:

Starting the programmer is done by a digital signal at input di1..3 or the è key

selected by parameter P.run. The programmer calculates a gradient from seg-

ment end setpoint and segment time.

This gradient is always valid. Normally, the programmer starts the first segment

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 setpoint).

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

or the è key is taken away), the programmer returns to program start and waits

for a new start signal.

Program parameter changing while the program is running is possible.

Changing the segment time:

Changing the segment time leads to re-calculation of the required gradient. When

the segment time has already elapsed, starting with the new segment is done di

rectly, where the set-point changes stepwisely.

Changing the segment end setpoint:

Changing the set-point leads to re-calculation of the required gradient, in order to

reach the new set-point during the segment rest time, whereby the required gra

dient polarity sign can change.
