3.9 Digital Input: Standard Functions
1/3/02 45
3.9.4 Manual (DI1) (TERMINAL 31)
When activated by a 24 VDC input, the controller switches to manual mode.
Regulated output is set by the potentiometer marked MANUAL. When deactivated,
the controller regulates from the manual value.
3.9.5 Tension Off (DI3) (TERMINAL 32)
When activated by a 24 VDC input, the output goes to zero and the regulator is reset.
This function is used at roll change. When input goes low, the regulator is set to the
new roll parameter. (Start Out)
3.9.6 Second Calibration (DI4) (TERMINAL 3) (Option)
When activated by a 24 VDC input, the second tension calibration range must be
used. Potentiometer R3 adjusts calibration for this range. Use this feature either for
operation over a wide tension range or for two different web paths.
