  ► Maintain the distances specified by the manufacturer of the pacemakers. – Pfeiffer Vacuum recommends a safety distance of at least 130 mm between the pacemaker and the product. ► Avoid the influence of strong magnetic fields by means of magnetic field shielding.
• Page 12
  ► Only operate the device in a dry environment. ► Operate the device away from fluids and humidity sources. ► Do not switch on the device if fluid has penetrated into it, instead contact Pfeiffer Vacuum Serv- ice. ► Always disconnect the current supply before cleaning the device.

• Page 13: Safety Precautions

  ► Operate the device away from fluids and humidity sources. ► Take special precautions if there is a risk of dripping water. ► Do not switch on the device if fluid has penetrated into it, instead contact the Pfeiffer Vacuum Service Center.

• Page 14: Proper Use

  The gauge can not be used for the measurement of highly flammable or combustible gases in the mix- ture with an oxidizing agent (e.g. atmospheric oxygen) within the explosion limits. The gauge can be operated with a Pfeiffer Vacuum total pressure measuring and control unit, or with an evaluation unit provided by the customer.

  Installation Fig. 2: Establishing the vacuum connection 1 Protective cap Tensioning piece Procedure 1. Ensure that the permissible operating temperature of the gauge is not exceeded. 2. Observe space required for the electrical connection (e.g. permissible bending radii for the ca- bles).

• Page 21: Establishing The Electrical Connection

  ► Only connect the product to devices which meet the following criteria: ● Requirements of the earthed protective extra-low voltage (PELV) ● Limited power source (LPS) Class 2 ► Secure the line to the product. – Pfeiffer Vacuum measuring and control equipment complies with this requirement. 21/52…

• Page 22: Measurement Cable And Hirschmann Cable Socket

  ► Always connect the supply earth (Pin 5) with the earth for the supply unit. ► Always connect the shielding (Pin 6) with the earth for the supply unit. To operate the gauge with a Pfeiffer Vacuum total pressure measuring and control unit, you will require a corresponding measurement cable from the ActiveLine Accessories.

• Page 23
  Installation Manufacturing a measurement cable 1. Observe the following steps to ensure optimum signal quality, whereby ground loops, differences in potential or EMC will influence the measuring signal. – Use a cable with braided shield and metallic connector housing. – Additional information regarding measurement cable type and conductor cross-sections can be obtained in the technical data.

• Page 24: Operation

  Operation 6 Operation Once the supply voltage has been established, the measuring signal is available at the electrical con- nection (Pins 2 and 3). Operating the gauge 1. Respect the stabilization period of at least 10 minutes. 2. Respect the relation between measuring signal and pressure. 3.

• Page 26: Gas Type Dependence

  The measuring signal is gas type dependent. The characteristics apply for nitrogen (N ), oxygen (O dry air and carbon monoxide (CO). When operating the gauge with a Pfeiffer Vacuum total pressure measuring and control unit (TPG), you can enter a calibration factor to adjust the displayed measured value.

• Page 32: Maintenance

  The dominant cold cathode measuring circuit for the low pressure range (< 1 × 10 hPa) has been cali- brated by Pfeiffer Vacuum to a fixed value at the factory. It is possible, however, to readjust the Pirani measuring circuit. Calibration has a negligible influence on the pressure range between approximately hPa and 10 hPa.
