LS22 Controller Options

For the needs of different processes, LS22 spinners come with three pulse-width modulated (PWM) controller options.

The programmable MP100 controller supports highly complex processes, with memory for a variety of event recipes that can be called by number. The software that comes with the MP100 handles as many as four fluids in up to 10 recipes with variable accelerations and speeds for coating, developing and cleaning processes. More extensive programming is also possible. A key panel and large alphanumeric display simplify operation and programming. The MP100 is compatible with a large number of simple and complex dispensers.

The PWM202 controller supports one-fluid coating or two-fluid developing processes with three independently controlled times/speeds. Three independent manually set digital timers support spin time settings of 0.1 to 99.9 and 1 to 999 seconds, minutes or hours. An LCD bar graph on each timer, dynamically displays the percentage of the remaining time, while the timer is active. A digital LED meter displays the motor rpm when the motor is running. The PWM202 is compatible with several simple dispensers.

The PWM202 and the MP100 controllers operate at 115 volts ac, 50/60 Hz. The controllers supply all power to the system, including 24 volts for dc circuit control. Transformers are available for 220 volt ac operation.

The PWM32 controller has a digital readout tachometer and a keypad entry for programming. The unit has multiple recipe memory (program sequences) and can store up to 10 separate recipes with up to 9 separate program steps per recipe. The liquid-crystal display (LCD) displays rpm, process times, programming prompts and input and system status information. The speed and acceleration can be set uniquely in every program step and the speed can be manually adjusted while the process is running.

The PWM32 controller has an internal transformer for 110/220 volt ac 50/60 Hz operation.

LS22 System Components
