WebPro Winder Tension Controller
Machine Sequence Logic and Connections
WARNING - Do NOT connect the digital inputs to a negative or AC supply, this will cause damage and
will invalidate the warranty.
The digital inputs are opto-isolated and overvoltage protected. The maximum input voltage is +24V DC.
The AUTO/OFF functions may be selected from the keypad if Enable MAN/AUTO/OFF keys is Enabled.
The full range of Machine Sequence Logic is selected externally, see Machine Parameters.
Disabled, the input is inactive.
0V=OFF, requires the input to be open to 0V with a volt free contact closure or logic switch - Option A,
or alternatively taken high ( +5 to +24V ) with a pull down resistor R< 1K
S to function - Option C.
0V=ON, requires the input to be taken to 0V with a volt free contact closure or logic switch - Option B,
or alternatively open to high ( +5 to +24V ) with a pull down resistor R< 1K
S to function - Option D.
Machine Start, this toggles between AUTO and tension OFF, "Soft Stop Time" will apply in clutch mode.
Select Auto, a pulse greater than 100mS will put the Controller into the Automatic control mode.
Select Manual, this feature does not operate in Winder Tension Controller.
Select Off, a pulse greater than 100mS will put the Controller into the tension OFF mode.
Diameter Hold, this will hold the current reel diameter value.
Diameter Reset, a pulse greater than 100mS will reset the held diameter value to the core value.
Batch Hold, this feature does not operate in Winder Tension Controller.
Enable Ext SP, this will allow an external tension set point to be used and will disable the keypad setting.
Select Auto; Select Off; the Controller will remain in the selected mode until an alternative input is
selected even after the primary contact closure or logic level is removed. However, if the contact is
maintained closed this will override any other contact or key.
Digital Output Connections
The digital outputs use open drain mosfets. The maximum that each output
can switch is +24V DC at 100mA. The output may be used as a TTL output
with a suitable pull up resistor. A freewheel diode should be connected
across any load inductance to prevent damage to the mosfet and to
suppress EMI.
When the low tension range is selected by pressing the LOW key the digital
output on TB4/11 will be switched OFF, switched ON in high tension range.
This may operate a relay to select the pads of a multipad clutch or the motor
torque range when in Torque control.
When mains powered, the total current that can be taken from the Controller 24V DC supply by the digital
outputs is 50mA maximum. When 24V DC powered this current will depend on the users supply.
The digital input is shown in the OFF position
