WebPro Unwind Brake Tension Controller
Before connecting the HCD to the mains supply, ensure that the mains voltage matches the HCD
requirements. Connect the HCD control input common to the WebPro controller “0V analog” mTB4 and
the HCD control + signal input to the WebPro controls “control out 0/+10V” or TB4.
Caution: The HCD controller signal input connections must be isolated from the mains supply
connections or damage to the WebPro and the HCD will occur.
PCB Link Positions
The links LK1 to LK5 MUST be in the proper positions for correct operation.
It may be found more convenient to position the links before connecting the Controller.
LK1 Excitation Voltage Position B
This gives 5.6V for Cleveland-Kidder transducers
LK1 Excitation Voltage Position A
This gives 10V for ACDF and foil transducers
LK2 and LK3
IN
For Cleveland-Kidder transducers to complete the bridge
LK2 and LK3
OUT
For full bridge transducers, the bridges are complete
LK4 and LK5 Gain
Position A
Normal gain for Cleveland-Kidder transducers
LK4 and LK5 Gain
Position B
High gain for Cleveland-Kidder transducers
LK4 and LK5 Gain
Position C
Normal gain for ACDF and foil transducers
LK4 and LK5 Gain
Position D
High gain for ACDF and foil transducers
The high gain positions providing three times the normal gain are used if the transducers are oversized
and there is insufficient signal level for accurate calibration.
Controller Connections
WARNING - Disconnect the Controller completely before any electric welding is undertaken on the
machine. Failure to carry out this precaution could damage the Controller and will invalidate the warranty.
WARNING - The PCB uses devices sensitive to electrostatic voltages. Do NOT touch any components
without first using proper electrostatic discharge ESD precautions.
The Controller uses Wago Cage Clamp terminals, it is recommended that the correct tool is used when
inserting the cables. Wago part number 210-120 is available from Wago or CMC Inc.
Do NOT strain the terminals or the PCB. The terminals are suitable for cable sizes 12-24 AWG, 0.1-
2.5sqmm. The cable ends should be terminated with ferrules or crimp tags.
It is necessary to remove the rear cover to connect the Controller, set the links and select the mains
supply voltage. Remove the rear cover and fit the cable gland (supplied loose) to the rear cover. Feed the
mains cable through the cable gland and connect to the two part connect as shown. Feed the transducer
