DFE WebHandler 3 Instruction Manual page 33

2 - If you are not connected correctly, after from 5 to 45 seconds, the program realizes that
you don't have a WebHandler connected and gives you the error message,
"COMMUNICATION ERROR: Please Check Cable Connection OR Heartbeat LED and restart
WH3 and PCWebLink.
Press "OK". You should then attempt to resolve the problem. However you can still view the
screens but you will not be communicating with the WebHandler, so the values will not be
correct.
(3) Using PCWebLink to operate the WebHandler controller
The Run screen is the standard status screen for operation. You can use it for operating the
controller and viewing tension, line speed (if calibrated), current controller output, and roll
diameter (if calibrated). You can also change Tension Mode (On or Off), Controller mode
(Manual or Auto), and Taper (on or Off). You can select Tension Display units and enter Auto
and Manual Setpoints, Taper Percent, and Web Width. Note that if you enter an erroneous value,
the WebHandler will reject it. NOTE: Always Store your changes before exiting program.
(4) Using PCWebLink to configure the controller
Other screens are available to assist in controller setup. To access these screens, go to the User
Screens menu on the tool bar. The following screens group similar parameters for easy setup:
