SMAX - SSI and analogue
5.2.5 STOP

input
It is used to execute the TEACH-IN procedure. It is active at HIGH logic level
(voltage greater than 10V must be applied). For any further information on
using the
START
 and
STOP

inputs refer to the “5.3 TEACH-IN procedure”
section on page 24.
5.2.6 Fault output
The Fault output is only available for AI1 current analogue output and is
intended to signal an error condition such as a circuit break.
To connect the Fault signal please refer to the examples in the sections
hereafter: “5.2.6.1 Fault output connected to a PLC input“ and “5.2.6.2 Fault
output connected to a relay“.
Please pay attention to the value of the R2 resistor (Figure 3 and Figure 4).
