LS22 Controller Options

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

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 controller operates 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.
