14.Use the Up and Down Arrow buttons to go to the next parameter to be modified. Repeat as required for any remaining parameters.

15.When all program modifications are completed, use the Up and Down Arrow buttons to go to parameter “0” then press the Enter button to return to run mode.

16.Remove the power source from the controller. Following the procedures in your facility, lockout or tagout the power source.

17.Remove the dust cover from the control enclosure.

18.At the connection end of the drive lift the black plastic cover up slightly then slide it out of the back of the drive.

19.Locate the jumper labeled “JP1”.

20.Move the JP1 jumper from the “ON” position to the “OFF” position.

21.Slide the black plastic cover back into position.

22.Install the enclosure cover.

23.Remove any lockout/tagout devices in use as per procedures in place at your facility, then connect the controller to the power source and power the unit up.

24.The drive is now ready to be used.

The required programming values for Extruder Tracking Control are located on drawing number A0541236, one of three drawings that are included with the additive feeder. If you do not have these drawings contact service to have them forwarded to you.

Parameter # 37 requires the installer to program the correct pulses per revolution from the extrusion machine.(See Chapter 5)

Extruder Tracking Control Application Notes

Input Pulse Signal Requirements

The drive uses a 5 volt DC square wave (TTL NPN type RPM signal) on its S2 input terminal as a reference signal from the extruder. Please contact us for application assistance if your extruder is not equipped with a method to provide this signal.

Minimum Input Pulse Rate

Extruder Tracking units are programmed to follow an extruder that provides eight pulses per revolution. Additive Feeders used in extruder tracking systems REQUIRE end user programming to match the master rate signal from the extruder’s screw if the signal does NOT provide eight pulses per revolution. The value programmed into parameter P37 must be set to match the number of pulses per revolution that the extruder generates.

In addition, the drive must be provided a MINIMUM of 240 pulses per minute to provide accurate results.
