2.1.3. 19) 24V Auxiliary outputs
On the instrument main board there are four programmable electrical outputs (24V DC /
100 mA maximum, outputs).
Unlike the valve code outputs, the auxiliary outputs reserved for a pneumatic function
are identified by the name of the function: stamping, automatic connector, etc. When
they are free and available for the operator to use they are called: auxiliary and the
position number.
Associated parameters to be adjusted: Auxiliary 1, Auxiliary 2, Auxiliary 3, Auxiliary 4.

2.1.3. 20) Mini valve
This function is dedicated to applications for small volume parts (below 10 cm
3
), and
has a base time of 0.01 s instead of 0.1 s.
Programming for the ATEQ D520 mini valve is identical to that for the standard ATEQ
D520.
Associated parameters to be set: A-Z Diff (Differential Auto-zero). This time can be
reduced as long as the values obtained are stable and repeatable.
) Select the option and adjust settings if necessary.
2.1.3. 21) No negative
The "No negative" function allows to reset the display of the measurement when the
flow goes to the negative, in this case, the display of the flow comes to 0 (zero).
This function is useful in the case of we don't want to give the information of a negative
flow to the operator (display) or to a PLC connected to the instrument.
) Select the option and adjust settings if necessary.
