Congratulations! You have purchased a precision vacuum positioning device from Nor-Cal Products. This unit is capable of many years of use with minimal care and maintenance. This manual is a tool to aid you in obtaining this service. We at Nor-Cal Products encourage your comments and suggestions on this manual. Product Description The EM 200 series precision manipulators are a family of aluminum units which offer exceptional value per dollar.
PAYLOAD CONSIDERATIONS The EMT Series instruments have a 20# equipment payload for standard vertical (NOT inverted) operation. This payload is based upon the total equipment load on the traveling flange with the base flange securely attached to the customers chamber, providing a strong and stable mounting. The payload center of gravity must be within the diameter of the traveling flange OD (Normally 2.75”) and within 8” of the flange face.
Lubrication *******THIS IS EXTREMELY IMPORTANT**********. All exterior bearings, micrometers, gears, gearboxes, and lead screws are lubricated with GHT-2 high temperature lubricant. The user may need to add more lubricant from time to time, depending on the frequency and temperature of bakeouts and operating environment. **************WARNING************ Additional lubricant must be added to the lead screw as the use and environment requires.
DO NOT RUN UNCONTROLLED BAKEOUTS OR BAKEOUTS OVER 200 C It is not necessary to remove the micrometers (on specials only,if any) prior to standard bakeout. For high temperature bake-out, or repeated bake- outs of long duration, we do recommend micrometer removal. All motors and limit switches/ position indicators must be removed during bakeout. We recommend limiting the temperature of the lubricant and the bakeout temperature to 200 C or less. See safety warnings under “Lubrication”.
Motorized operation All axis of your manipulator can be motorized. Retrofit kits are available for field installation. Please consult the factory for further information. All motors and limit switches/ position indicators must be removed before bakeout. REMOVE AND ADJUSTMENT PROCEDURES Z drive: The Z drive motor is removed by first releasing the clamp screw on the drive shaft. This screw is accessed through a hole in the aluminum spacer between the motor mounting flange and the gearbox.
