5.9 TUMBLER (OPTION) SPEED CONTROL
The Amber/Orange pushbutton lets you check rotation prior to coating, making sure the tumbler can
rotate the load and that there are no obstructions to hinder rotation in the chamber.
The Amber/Orange light will illuminate when the tumbler is enabled through PLC logic.
NOTE: In order to enable rotation, the Vaporizer switch must be set to ENABLE.
The tumbler can only be activated by pressing the Amber/Orange pushbutton or through PLC logic.
PLC logic:
The tumbler will be enabled when the conditions below are satisfied in this sequence:
1. Vaporizer switch is set to the ENABLE position.
2. All process heaters are within limit (furnace and gauge tube heaters)
3. Chamber pressure has reached below the base pressure set point.
4. Chamber pressure then rises above the base pressure set point.
The tumbler will stop after the end of the run.
Adjustments:
1. Read “Installation and Operation Instructions for KBWS Whisper Drive” located in the Technical
Literature section.
2. Disconnect the main power from the PDS 2010.
3. The tumbler drive assembly uses a 130VDC motor. For the 130VDC motor, set Jumper J1 to the
“90V” position.
4. Reconnect the main power and power up the unit.
5. Set tumbler speed to 2 RPM at 0% and 10 RPM at 100% by adjusting the MIN and MAX trimpot.
a) Disconnect the tumbler motor cable from the connector located on the top of the 2010 unit.
b) Set the voltmeter to DC voltage and plug positive to pin #2 and negative to pin #4.
c) Set speed control trimpot to 0. Depress and hold the amber pushbutton. Adjust the MIN trimpot
until Voltmeter reads 18.5 VDC.
NOTE: You may not be able to reach the exact voltage.
d) Set speed control trimpot to 100. Depress and hold the amber pushbutton. Adjust the MAX
trimpot until Voltmeter reads 92.8 VDC.
NOTE: You may not be able to reach the exact voltage.
e) Release the amber pushbutton and reconnect the tumbler motor with the 2010 tumbler connector.
f) Verify tumbler operation and calibration.
For more adjustment information (Acceleration, Deceleration, etc.) see the operation instructions for the
KBWS Whisper Driver in the Technical Literature section.
