Headway 1-EC101D-R485 Photo-Resist Controller for a Spinner
Specifications are from Headway and may vary slightly due to upgrades, options or revisions this unit may or may not have.
The chuck and motor assembly are not included. There are many kinds and sizes of chucks and bowls available from the factory.
This controller was set up for a R485 Spinner which can still be gotten from the factory I believe.
The unit powers up but we do not have the expertise to test it after that.
Services: 3A, 115V, 50/60 Hz, Single Phase
The EC101D spinner series offers high acceleration, high torque, electronic speed regulation, automatic cycle control, and automatic braking.
The Motor Control Unit contains a full wave SCR motor drive circuitry. The unit includes a digital tachometer along with speed and timer potentiometers. The acceleration adjustment is accessible on the front panel. The digital tachometer on the front panel indicates spinner speed directly in thousands of RPM.
The EC101D spinners are supplied with a dual function footswitch. The front part of the footswitch initiates the spin cycle. The rear part stops the cycle if desired.
High Adjustable Acceleration: The acceleration is set at the factory at approximately 600 milliseconds to 10,000 rpm. Acceleration may be easily adjusted from 200 milliseconds to 1.2 seconds. This adjustment is accessible on the front panel.
Wide Adjustable Speed Range: Standard speed is variable from approximately 50 to 10,000 rpm.
Automatic Cycle Control: In the automatic mode, the footswitch initiates a complete spin cycle. Vacuum is automatically applied; spin started and timed, brakes applied at the present time, and the vacuum released. The timer resets for the next cycle. The standard timer range is 1 to 999 seconds.
Automatic Dynamic Braking: The automatic dynamic braking system quickly stops the spinner at the end of the spin cycle. In the event of a vacuum failure, the dynamic brake will normally stop the spinner before the substrate can be thrown.
Vacuum Interlock Protection: Adjustable vacuum interlock circuit protects the operator and the substrate. If the substrate is not properly seated or if the vacuum source is inadequate, the spinner will not operate. If the vacuum drops during a spin cycle, the machine will stop. A warning buzzer indicates vacuum difficulties when the start switch is pressed.
Headway R485 Bowl Assembly Description:
The R485 Bowl Assembly is capable of spinning up to 3.5" diameter substrates. The bowl arrangement is designed for minimum space requirements. The spinner has a rectangular box with a stainless bowl and fume exhaust port.
Speed Range: 50 to 10,000 rpm (All Series)
Adjustable Acceleration: 200 milliseconds to 1.2 seconds
Utility Requirements: 115 VAC 50/60 Hz
Vacuum Requirements: 23" HG (separate vacuum source required)
