Table 9-2: Summary of status outputs
9.2.3 Analogue inputs
Four analogue inputs are provided, to enable customer input of setpoints. Depending on the
output mode selected by the operator, one or more of these setpoints may be used to control
the operation of the SFC. Alternatively, fixed setpoints as entered into the GDM may be used.
The source for each setpoint may be individually configured from the GDM.
Table 9-3 summarizes these analogue inputs. Two inputs are for +/-10V and the other two are
for 0-20mA or 4-20mA.
