Page 27: Chapter Two: Installation
Chapter Two: Installation How To Unpack the Type 1249 Unit MKS has carefully packed the Type 1249 unit so that it will reach you in perfect operating order. Upon receiving the unit, however, you should check for defects, cracks, broken connectors, etc., to be certain that damage has not occurred during shipment. -
Page 28: Interface Cables
January 1, 1997, some products shipped to the European Community must also comply with the Product Safety Directive 92/59/EEC and Low Voltage Directive 73/23/EEC, which cover general safety practices for design and workmanship. MKS products that meet these requirements are identified by application of the CE Mark. -
Page 29: Generic Shielded Cable Guidelines
Chapter Two: Installation Interface Cables Generic Shielded Cable Guidelines Should you choose to manufacture your own cables, follow the guidelines listed below: 1. The cable must have an overall metal braided shield, covering all wires. Neither aluminum foil nor spiral shielding will be as effective; using either may nullify regulatory compliance. 2. -

Page 39: Bias Adjust Potentiometer
Chapter Three: Overview Instrument Components Bias Adjust Potentiometer The bias adjust potentiometer establishes a valve position offset. Since each valve requires a slightly different voltage level to move from the fully closed to slightly open position, the bias adjust allows the 1249 unit to compensate for the difference. Use the bas adjust pot to determine the minimum voltage required to move your valve from the fully closed to the slightly open position. -
