HOW TO USE DIGITAL INPUT TO CHANGE THE SETPOINT VALUE

[Pixsys tecnico 1]

PIXSYS controllers ATR142, ATR243 and ATR401 are provided with a digital input, which might be used to change the setpoint value. This is useful whenever the same process/application requires different setpoint values.

After entering the Configuration level (as descrive in the User manual of each device) please proceed as follows:

-Scroll the listo f parameters until you reach parameter [dgt.i] (for ATR243 and ATR401) or [oPNo] (for ATR142)
-Choose option [2t.S] if you want to change the setpoint value according to the status of digital input (ex. setpoint 1 if digital input is open; setpoint 2 if digital input is closed)
-Choose [2t.Si], [3t.Si] or [4t.Si] if you want to recall 2, 3 or 4 different setpoints at each closing of the digital input

All the different setpoint values must be entered as usual by pressing the SET key during the operation.

N.B.
On ATR142 digital input is not available when using PT100, NI100, NTC, PTC, PT500, PT1000 and linear potentiometers

On ATR243-20ABC, digital input is not available when using PT100 and NI100.
