Line Speed Calibration And Setup - DFE WebHandler 3 Instruction Manual

B. USING A REMOTE TENSION AMPLIFIER (RTA) SUCH AS THE DFE FIREGUARD INDICATOR.
1. Press both ! and " keys simultaneously to enter function group menus. Select the Set-up Menu and
press OK . Navigate to Tension Source. Press
right edge of the second line, then line 2 will blank out.
2. Press EXIT
and choose your full scale tension range from the list. If your desired tension range is not shown, choose
"NonStandard"
Full scale Tension Ranges for the Transducer input and for the External inputs are independent from each
other. The Tension Range which applies to your chosen setpoint source must be set (and if Transducers are
used, they must be calibrated), otherwise the controller will display the "Uncalibrated" message.

3.3 LINE SPEED CALIBRATION AND SETUP

Line Speed Calibration is required when you want to use the WebHandler in any of the following modes: Line
Speed Follower; Diameter Compensated Line Speed Follower; Taper by Diameter Calculation; or Soft Start by
Line Speed. There are three kinds of Line speed signals which can be used: a 0-10Vdc signal which may come
from a drive or interface card; a high voltage DC tachometer signal; or a Pulse tachometer or encoder signal.
Refer to step A, B, or C as appropriate for the type of Line Speed signal you have, then jump to step D.
A. CALIBRATION FOR 0-10V LINE SPEED SIGNAL
1. Verify that your 0 to 10V Line Speed signal actually produces 0V at zero speed, and 10V at full speed.
Verify that your Line speed signal is connected to Terminal Board at TB101 pins 8 (Signal +) and 9
(Signal Return).
2. If either Diameter Compensated Line Speed follower or Taper by Diameter Calculator modes are to be
used with a 0-10V roll speed signal, verify that your 0-10V Roll Speed signal actually produces 0V at
zero speed, and 10V at full speed. Also verify that your 0-10V Roll speed signal is connected at TB101
pins 10 (Signal +) and 11 (Signal Return).
3. Go to step D for setup.
