SETPOINT SOURCE
Select the tension setpoint source. The tension setpoint is either the tension input (Term.16) or the Ethernet. The
software is factory calibrated for using a 1K to 10K potentiometer on Term.15 through Term.17 with the wiper on
Term.16. When using an external 0-10 VDC voltage source see Section 9.3 for recalibrating the tension setpoint
input.
6.2.2.5
DIGITAL INPUT ACTIVE LEVEL
The digital control inputs may be either Active Low or Active High. The software is factory configured for Active
Low inputs. See Section 5.2 and Figure 4.
