Calibrate tension through the fieldbus procedure

The DLCA NET-S1 uses Precision calibration. Precision calibration
is used when applying a known weight with a rope in the web
path to the load cells for calibration. Typically this known weight
should be 10% of the load cell rating or greater.

The

Command Interface

is used to perform the calibrations.

A command request is entered in the

Command Request

. The

Command Response

will show the progress of the command and

when the command is complete. Errors will also be shown.

Parameters for Tension Zone 1 can be accessed in the group

Configuration Tension 1

and those for Tension Zone 2 can be

accessed in the group

Configuration Tension 2

LC1 - Roll Weight load cells on channel 1.

LC2 - Web Tension Load Cells on channel 2.

RW - Roll Weight

T - Web Tension
