    A separate low voltage power supply connects to the HPQ2-IP control unit. The HPQ2-IP is designed to be operated from an IBM compatible PC running either Process Eye Professional or Easyview software. Communication between the PC and the HPQ2-IP is via an Ethernet link.
  • Page 13: Control Unit Overview

    3. Control Unit Overview The HPQ2-IP control unit is a single unit incorporating all the necessary power supply and data acquisition electronics for the residual gas analyser. Power is derived from a dedicated low voltage power supply which is supplied as part of the standard package.

    The indicator is lit when power is supplied to the HPQ2 unit. Comms This indicator will flash to show a comms event to the HPQ2-IP unit. If there are no active communications with the HPQ2-IP, this indicator will pulse at approximately 2Hz, depending on the RGA software version used.
  • Page 16: Audio Output

    The Analog Input / Output connector is a 15 way D-Type socket mounted on the rear panel of the HPQ2-IP unit and labelled ANALOG I/O. It consists of; one analog output 0 to +10V and four quasi-differential analog inputs 0 to ±...

    It allows an independent total pressure gauge or a signal from a vacuum control system to be connected to the HPQ2-IP. It is the most effective of the trips available and we would always recommend its use. The external trip input can be driven in three ways.

    4.1 Unpacking When you receive the HPQ2-IP carefully check each item before removing the foam packaging and plastic wrapping, to ensure that no physical damage has occurred during shipment. Also, make sure all items have been received correctly by checking each item against the enclosed packing slip.

    HPQ2-IP control unit. It is permissible to expose the analyser to high pressure, even above atmosphere, but the filament must be switched off.
  • Page 21 The HPQ2-IP will be more susceptible to drift in the location and height of peaks if it is mounted in a different orientation to that described above and it may not meet its published specification.
  • Page 22: Control Unit Installation

    Rotate the clamping ring on the RF/analyser connector so that the slot (which will be directly below the threads of the M5 socket set screw) lines up with the keyway on the connector tube. Hold the HPQ2-IP control unit so that the keyway lines up with the locating key on the analyser flange.
  • Page 23: Electrical Connections

    Attach the line cord to the power supply. The power supply will automatically set itself to operate with the local line voltage. When power is applied, the LED on the rear of the HPQ2-IP will illuminate. In the case of an Ethernet connection, connect a cat5 patch lead to the socket marked “ETHERNET”.
  • Page 24: Baking

    6. Baking The HPQ2-IP control unit should not be exposed to temperatures above 40 C so it should be removed from the analyser during baking. The analyser may be baked up to 250 C but care should be taken to avoid exposing the ceramic feedthrough to sudden changes in temperature.

    The serial number is engraved on the analyser flange and will begin with the letters “LM”. The HPQ2-IP analyser can be broken down into four separate areas by virtue of their function.
  • Page 26: Maintenance Of Your Analyser

    These, being insulators, have a far more noticeable effect upon the performance of the source and therefore a more frequent cleaning program should be undertaken. HPQ2-IP SP101009.102 – 10 October 2012 MKS Instruments, Spectra Products...
  • Page 27: Failed Filaments

    In the remainder of this section we describe how to replace filaments, replace the ion source and clean the ion source as an assembly. The HPQ2-IP analyser has been designed to allow these jobs to be carried out with minimal training and specialised equipment.

    Now attach the first meter lead to pin 3 and check to pins 4 to 12. Proceed around the feedthrough until all possible connections have been checked. HPQ2-IP SP101009.102 – 10 October 2012 MKS Instruments, Spectra Products...
  • Page 29: Checking Filaments

    If the meter reading suggests that the filament is good but the control unit shows a filament fail the most likely cause would be a break down in electrical continuity. Examine the RF/analyser connector on the front of the HPQ2-IP control unit, check that none of the gold sockets are pushed out of place.

    4. Repeat step 3 for the other filament connection. 5. Check with your Ohmmeter for shorts. 6. Replace the analyser into your vacuum housing and again check for shorts or grounding to the outer vacuum housing. HPQ2-IP SP101009.102 – 10 October 2012 MKS Instruments, Spectra Products...
  • Page 32: Ion Source, Replacing And Cleaning

    7.10 Ion source, replacing and cleaning The HPQ2-IP analyser design permits the removal of the ion source as one complete assembly which can be replaced or cleaned as an assembly. The ion source automatically aligns on the main analyser assembly allowing it to be easily replaced without the need for any special jigs.
