Table 21 Initial Settings 73,Safety Procedures and Precautions Introduction. Safety Procedures and Precautions, The following general safety precautions must be observed during all phases of operation of. this instrument Failure to comply with these precautions or with specific warnings. elsewhere in this manual violates safety standards of intended use of the instrument MKS. Instruments Inc assumes no liability for the customer s failure to comply with these. requirements,DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT.
Do not install substitute parts or perform any unauthorized modification to the instrument. Return the instrument to an MKS Calibration and Service Center for service and repair to. ensure that all safety features are maintained,SERVICE BY QUALIFIED PERSONNEL ONLY. Operating personnel must not remove instrument covers Component replacement and. internal adjustments must be made by qualified service personnel only. DO NOT SERVICE OR ADJUST ALONE, Do not attempt internal service or adjustment unless another person capable of rendering first. aid and resuscitation is present,GROUNDING THE PRODUCT. This product is grounded through the grounding conductor of the power cord To avoid. electrical shock plug the power cord into a properly wired receptacle before connecting it to. the product input or output terminals A protective ground connection by way of the. grounding conductor in the power cord is essential for safe operation. DANGER ARISING FROM LOSS OF GROUND, Upon loss of the protective ground connection all accessible conductive parts including. knobs and controls that may appear to be insulating can render an electrical shock. USE THE PROPER POWER CORD, Use only the power cord and connector specified for your product Use only a cord in good.
Introduction Safety Procedures and Precautions,USE THE PROPER POWER SOURCE. This product is intended to operate from a power source that does not apply more than 250. Volts RMS between the supply conductors or between either of the supply conductors and. ground A protective ground connection by way of the grounding conductor in the power cord. is essential for safe operation,USE THE PROPER FUSE. Use only a fuse of the correct type voltage rating and current rating as specified for your. KEEP AWAY FROM LIVE CIRCUITS, Do not replace components with power cable connected Under certain conditions dangerous. voltages may exist even with the power cable removed To avoid injuries always disconnect. power and discharge circuits before touching them, Definitions of WARNING CAUTION and NOTE messages used throughout the manual. Warning The WARNING sign denotes a hazard It calls attention to a. procedure practice condition or the like which if not. correctly performed or adhered to could result in injury to. Caution The CAUTION sign denotes a hazard It calls attention to an. operating procedure practice or the like which if not correctly. performed or adhered to could result in damage to or destruction of. all or part of the product, Note The NOTE sign denotes important information It calls attention to a.
procedure practice condition or the like which is essential to highlight. Chapter One Introduction,Chapter One,General Information. Introduction, The Type 655A instrument is a self tuning pressure controller for throttle valves It can. supply 15 Volts to power and provide a readout for an attached capacitance manometer The. self tuning feature of the Type 655 unit determines system characteristics necessary for. control This feature takes into account time constants transfer functions of the valve and. plumbing valve gain pump speed and many other important parameters when determining. the system characteristics The 655 unit also includes an adjustable softstart function to. minimize turbulence in the chamber and contamination of the process local remote. transducer zeroing capability and two process limit relays to indicate if the pressure deviates. from the desired trip points, Located on the front panel is a key lock switch used to select front panel or rear panel control. The switch can lock the front panel controls as a safety measure to prevent accidental. command entries The default window display on the front panel shows the pressure readout. and the valve position open The pressure readout can be displayed in units of Torr. mTorr mbar bar Pascal kPa cmH2O or inH2O Five reprogrammable setpoints are. provided each one having the option of being setup for pressure or position control Valve. open close and stop functions are also provided on the front panel for use in system setup and. diagnostics, The 655 instrument has a high powered driver to operate the MKS Type 654 throttle valve up. to 100 mm 4 with vacuum shut off capability giving the unit a control range from 10 4 to. 760 Torr with the appropriate pressure transducers Appendix B Product Compatibility. beginning on page 69 lists all MKS products that are compatible with the 655 All MKS. linear Baratron transducers are compatible with the 655 controller which is equipped with a. high capacity power supply The 655 unit contains a battery backed memory module which. stores configuration and learned system information while power is off There is also an. optional valve failsafe battery backup available The optional battery backup allows user. configuration of the 655 instrument to drive a valve open or closed upon an AC power failure. How This Manual is Organized General Information,How This Manual is Organized.

Chapter Three gives an Overview of the Type 655 Pressure Controller It describes the. components on both the front and rear panels and discusses local and remote operation It also. provides information about the electrical connections. Chapter Four Setup explains how to connect a valve and set up the 655 Pressure Controller. using the menu selection prompts displayed on the front panel. Chapter Five Local Operation describes how to operate the instrument from the front panel. and includes detailed instructions for using each of the functions available in local mode. Chapter Six Remote Operation describes RS 232 control and the digital logic operation. Chapter Seven Maintenance provides instructions on how to replace the battery backed. memory module as well as the optional valve failsafe battery. Appendix A lists Product Specifications for the Type 655 instrument. Appendix B supplies information about MKS Compatible Products. Appendix C describes the Displayless unit and how it differs from the standard 655 unit. Appendix D Initial Settings lists the initial settings of the controller. Customer Support, Standard maintenance and repair services are available at all of our regional MKS Calibration. and Service Centers in North America Europe Israel Japan Korea and Taiwan In addition. MKS accepts the instruments of other manufacturers for recalibration using the Primary and. Transfer Standard calibration equipment located at all of our regional service centers Should. any difficulties arise in the use of your Type 655 instrument or to obtain information about. companion products MKS offers contact any authorized MKS Calibration and Service Center. If it is necessary to return the instrument to MKS please obtain an ERA Number Equipment. Return Authorization Number from the MKS Calibration and Service Center before shipping. The ERA Number expedites handling and ensures proper servicing of your instrument. Please refer to the inside of the back cover of this manual for a list of MKS Calibration and. Service Centers, Warning All returns to MKS Instruments must be free of harmful. corrosive radioactive or toxic materials,Chapter Two Environmental Requirements.
