6.1
ALTERNATE TENSION INPUTS
100 mv/v TENSION SENSORS
On the main PCB cut jumpers JP11 and JP12.
Connect wires to TB2 and TB3 as shown using shielded
wiring. Only one full bridge can be used.
10 vdc TENSION SIGNAL
On main PCB cut jumpers JP10, JP11, JP12 and JP13.
Connect signal between terminals TB2.1(+) and TB2.2(-)
using shielded wiring. TB2.2(-) should also be connected to
TB3.1 (GND).
6.2 DIAMETER
INPUT
The DIGITRAC 2 uses the diameter of the roll on unwinds and rewinds for inertia compensated stopping and on
rewinds for providing taper tension. When no diameter input is provided the DIGITRAC 2 estimates diameter.
Using a diameter input gives more accurate results.
Select the DIAMETER INPUT TYPE under PROGRAM-CONFIGURE. Connect a diameter sensor between
TB3.7(+) and TB3.6(-) using shielded wiring.
VOLTAGE (0 to 10 vdc) Voltage must be proportional to diameter (i.e. the output at core cannot be 0 vdc).
Select
)VOLTAGE( on JP15 on the main PCB.
