Connection example 2 (for I/O1 and I/O2):
An analog input can be connected to a tachometer generator. The
maximum output voltage of the tachometer should be + 35.0 V (see
illustrated example in figure below).
Both circuit examples (the NTC diagram above and the Tachometer below) are only
illustrations to show the aim of the analog inputs.

How to use these pins as digital inputs (Pin 4, 5, 6)
These pins are high active when used as digital inputs, so you can set V
IN(LOW)
and
V
IN(HIGH)
to any levels within the range from +0 to +35.0 VDC. The High and Low
levels can be set by using the PFAL command (e.g.
PFAL,IO
0[1,2]
.Config=DI,5,10
)
-
where 0, 1 and 2 are indexes corresponding to IO1 (pin 4), IO2 (pin 5) and IO3 (pin 6)
respectively. While the value 5 and 10 are min. and max. voltages that will be used to
generate Low and High events respectively.
generate Low and High events respectively.
Detailed information can be found in
software manual “steppIII_fox_bolero_lt_PFAL_Configuration_Command_Set.pdf“.
The figure below illustrates how these inputs can be used in practice. When the
running firmware detects input changes from High to Low or vice versa, it
generates a Falling or Rising edge Event respectively, therefore depending on the
alarm type, the FOX can react to the input changes and release different alarms
such as sending out an SMS, email message, TCP packet, opening a CSD
connection or activating an output port. The alarm type is user-dependant.
