  • Page 6: Introduction

    INTRODUCTION The Jerome 631-X Hydrogen Sulfide Analyzer is an ambient air analyzer with a range of 0.003 ppm to 50 ppm (parts per million). The Jerome 631-X is for vapor use only. DO NOT allow the probe or the instrument's intake to be exposed to any liquid, dust or other foreign material.

  • Page 7: Principle Of Operation

    Applications • Ambient air analysis • Odor nuisance monitoring • Regulatory compliance • Control room corrosion monitoring • Quality control • Scrubber efficiency testing • Accuracy check for other hydrogen sulfide monitors and control systems • Hydrogen sulfide source detection •...

  • Page 8: Zero Air Filter

    Zero Air Filter The Zero Air Filter removes mercury vapor, mercaptans, and hydrogen sulfide from the air sample. Readings with the filter installed should be near zero. Because air that is cooler than the instrument will cause low readings and warmer air will cause higher readings, the Zero Air Filter should be used to equilibrate the unit to ambient air.

    Daily Operations Before each day's use of the Jerome 631-X, perform the following steps to verify proper instrument operation: • Press the power ON button. The digital meter displays 000. (Disregard the digital meter's initial momentary reading.) Recharge or replace the battery pack if the LO BAT indicator REMAINS ON. Refer to “Charging Batteries”...

  • Page 12: Sensor Regeneration

    Sensor Regeneration Sensor regeneration is needed to clear the 631-X sensor of any accumulated hydrogen sulfide. This simple procedure should be done: • At the beginning of the day on which the instrument is to be used. • During the day when the sensor becomes saturated. •...

  • Page 13: Zero Adjust

    Zero Adjust • To ensure air entering the instrument is clean, install the aero air filter in the instrument’s intake and sample until the readings stabilize. • While pressing the ZERO button, turn the ZERO ADJUST potentiometer (shown at right) using the trimmer tool until the digital meter reads 0.

  • Page 14: Sample Mode

    Sample Mode This is the standard operation mode and is used for optimum accuracy. • Press the power ON button. The LCD displays 000. Disregard the LCD's initial momentary readings. Recharge or replace the battery pack if the LO BAT indicator REMAINS ON, see page 17 and/or page 21 if necessary.

  • Page 15: Survey Mode

    Survey Mode The survey mode takes samples every 3 to 20 seconds automatically. The length of time varies with the hydrogen sulfide concentration. Use this mode to locate the source of hydrogen sulfide, such as a leak, a hot spot, or to assess areas of potentially high hydrogen sulfide concentrations. After the survey mode is activated, the 631-X samples continuously.

  • Page 16: Operating On Ac Power Or Generator

    Operating on AC Power or Generator • For stationary use, the 631-X may be operated on AC power. Operating the instrument on AC power at all times eliminates the need for the battery pack and its necessary maintenance. The battery may be unplugged or removed completely whenever the instrument is operating on AC power.

  • Page 17: Charging Batteries

    Charging Batteries • Press the power OFF button. • Connect the AC power cord between the 631-X power receptacle and an AC power source. Complete battery recharging takes 14 hours. The 631-X contains a trickle charger so it may be continually plugged into an AC power source without damaging the battery pack.

  • Page 18: Maintenance

    MAINTENANCE Preventive Maintenance Calendar To keep the Jerome 631-X operating at peak performance, follow the maintenance schedule below as a guide. Since maintenance is more a function of application and amount of use rather than time, your requirements may be different from the listed schedule. Call AZI Customer Service at 800-528-7411, 602-470-1414, or e-mail support@azic.com for additional guidance for your environment and operation.

  • Page 19: Flow System

    Flow System The Jerome 631-X's flow system is the crucial link between the sensor and the sample. For the instrument to perform correctly, the flow system must be properly maintained. The user maintainable components of this system are the intake filter (.25 inch fritware), two scrubber filters and connecting tubing.

  • Page 20: Internal Filters

    Internal Filters • Replace the internal filters after six (6) months of use, or as needed. • Press the power OFF button and unplug the power cord. • Remove the two (2) side screws from the intake end of the instrument and open the case. •...

    Replacing the Battery Pack • Press the power OFF button. • Unplug the power cord. • Remove the two (2) side screws from the intake end of the instrument and open the case lid. • Disconnect the battery connector from the board. •...

  • Page 22: Changing The Fuse

    Changing the Fuse If the instrument display reads .P.P.P when the instrument is connected to AC power or when REGEN is pressed, or if the battery will not charge, the fuse may need to be replaced. The AC line power could also be less than 100 VAC (220 VAC). Check the fuse with an ohmmeter and the AC line power with a voltage meter.

  • Page 40: Appendix D - Jerome 631-X Option Board

    APPENDIX D - JEROME 631-X OPTION BOARD Proper use of this board requires that the base instrument be fully functional and set correctly for the intended operation. Auto-Zero With the option board installed, the 631-X has a limited auto-zero function. This function cannot be disabled and is transparent to the user.

  • Page 41: Timed Regeneration

    • In some cases, the instrument cannot resume sampling after regeneration. .L.L.L appears on the display when the ZERO button is pressed and the error message “manual bridge adjust needed” is added to the notes column of the JCS text file when the JCS is used. If this problem persists, it may be necessary to re-set the auto-zero.

  • Page 42: Auto-Sample

    Auto-Sample If a data logger is connected and operating in the manual sampling mode or a data logger is not connected the following automatic sampling rates may be selected with SW100 dip switch settings: Dip switch settings This auto-sample function will not function if a data logger is connected and operating in automatic sampler mode programmed through the JCS.

  • Page 43: Connection And Setup

    Jerome 631-X instruments shipped after early 1995, are capable of providing 0-2 volts analog output. Instruments shipped before that time can be upgraded by a firmware update and adjustment. Instruments that are capable of 0-2 volt output can be upgraded to the 4-20 mA output with the addition of an option board upgrade.
  • Page 44 • The 4-20 mA passive receivers must not contain a voltage source to power the loop current. They do require the addition of a separate isolated power supply. Typically a supply that delivers 15 to 20 volts DC at 50 mA is sufficient. Wire these as in Figure 3.

  • Page 45: Fresh Air Solenoid

    Fresh Air Solenoid An external three-way solenoid can be used to provide fresh air or conditioned air during sensor regeneration. This may be necessary if the sample stream lacks molecular oxygen. A low current six volt DC solenoid, connected between pins 19 and 11 of the 25 pin rear panel connector, will be energized during the regeneration cycle if the option board SW100 switch 6 is placed in the OFF position.

  • Page 46: Dc Power Operation

    DC Power Operation Instruments with the 631-X option board modification can be used with any +12 VDC source for continuous operation, if the AZI Power Inverter Kit, P/N Y031 0902 is installed along with the option board. To preserve the life of the DC power source, usually a car or truck battery, the power inverter will switch on automatically to supply the AC necessary for regeneration only.
  • Page 47 Ensure that the inverter’s power switch is in the “OFF” position. LEAVE the power switch in the “OFF” position at all times. The interface board will activate the inverter when necessary. If the inverter power switch is placed in the “ON” position, it will cause a continuous drain on the external 12-volt power system.
