FREE PROGRAMMABLE INPUTS
Ø PROGR. INPUT
Ø ADDITIONAL INPUT 1
Ø ADDITIONAL INPUT 2
Ø ADDITIONAL INPUT 3
In the basic version 1 programmable input is available.
As an option with the "I / O expansion board" are another 3 Inputs available. Thus the
sampler can be controlled with a digital pulse (eg with external PLC).
Each INPUT (1-3) can be programmed out of the following list:
Ø NO FUNCTION
(turn off of the Input)
Ø PRG. START PULSE
(if selected, Program x will be started)
Ø PRG. STOP PULSE
(if selected, Program x will be stopped) (Back with ESC)
Ø PRG. RUN DURING PULSE
(During continuous signal, Program is running. If Signal drops down,
program stops.)
Ø DISTRIBUTOR PULSE
Pulse signal: <= 3sec means "next bottle"
>= 5 sec means "move to bottle 1"
Ø SAMPLE PULSE
Pulse means "take a sample"
Pulse signal must be > 50ms!
Remark: This feature is only available if no program is running. The unit is
in this case completely controlled externally (eg PLC)
