  display below appears (audible / visual alarms are
  also activated). It must be switched off.
Sensor check

• A diamond symbol appears next to each sensor to
  confirm that the sensor
        – is working correctly
        – is being zeroed


• When sensors are zeroed correctly a tick appears
  next to each sensor
Zero fault

• If sensor(s) fail the zero check
  at the end of warm-up,
  the alarms activate.
  The display will show a spanner.
• To acknowledge the alarm, press the RH button
  once.The instrument continues to show a flashing
  spanner symbol alternating with the faulty sensor
  zero reading.
Normal operating display

• When warm-up is completed successfully, back-light
  switches off and normal operating screen is shown
  as follows




• Each gas range is displayed
• Display back-light can be manually switched on with
  a single press of the RH button. It remains on for 20
  seconds and then switches off
Normal operating display (2)

• During normal operation where the calibration date
  has expired, a warning flag will flash on the display
  every 30 seconds to warn the user that the expiry
  date has been exceeded.

  Press the RH button to switch screen
  light on. Press RH button again
  while light is on to view maximum
  values for each gas.

• Press RH button again to view the
  minimum gas values for each range.

• Stored readings can be removed from memory by
  pressing holding the RH button for 2 seconds
Remote sampling / pre-entry check

• Remote sampling is carried out with the in-built
  electric pump or by the hand aspirator
  – Press and hold the RH button and the pump (if fitted) will run at normal
    speed for remote sampling.
  – When the pump is running at normal speed, a pump symbol rotates
    in the display.
Attach tubing
• Remote sampling
  – Tygon tubing with ID of 4mm is used in combination
    with the bayonet connector
  – Push quick connector
    on to the inlet nozzle
  – Turn clockwise until
    locked in place
Alarms

• All gas ranges have alarm limits that trigger an alarm
  when the measured value exceeds the set level
• The audible alarm sounds, LEDs flash red, the
  instrument vibrates and the gas range in alarm
  flashes on the display
  – Flammable LEL Alarm Limits - Up to 2 alarm levels are programmable
  – Over-Range Flammable Gas Alarm - If the flammable gas readings
    exceed 120% LEL, a safety alarm is activated
  – Oxygen Alarm Limits - Up to 1 upper and 2 lower alarm limits are
    programmable
  – Toxic Alarm Limits - Up to 2 instantaneous and 2 Time Weighted
    Average (TWA) alarms are programmable for each toxic range
Alarms (2)

• The instrument display will signal the range in alarm.
  – Example of Lo Lo Oxygen Alarm Display




  – Example of HiHi LEL Alarm Display
Alarms (3)

• Alarms can be latching or non-latching
  – Latching - alarm will stay on until the user resets by a press and hold
    of the RH button when the gas level return to within the pre-set alarm
    limits

  – Non-Latching - the audible and visual alarm will reset automatically
    when the reading returns to within the pre-set alarm limits
Alarms (4)

• Acknowledging Gas Alarms
  – Once in a safe gas free area, or the gas reading has returned to within
    pre-set limits, press and hold the RH button to acknowledge/clear the
    alarm sounder and extinguish the red LED’s.

  – Alarms can have the mute function enabled or disabled
Alarms (5)

• Muting Gas Alarms
  – Alarms can have the mute function enabled or disabled
  – This means the audible alarm can be silenced for 60s.
  – If the alarm is non-latching, after 60s it will operate according to the
    gas concentration at that moment. I.e. if safe, it will remain silent, if
    above alarm level it will start sounding again.
  – If the alarm is latching, after 60s the audible alarm sounds again,
    regardless of the concentration. The user can then mute it again (if the
    concentration is above the alarm level, or acknowledge it if it is below).
Alarms (6)

• High Flammable Gas Over-Range Alarms
  – Protects the user from danger in event of the LEL sensor being over
    exposed to a high concentration of flammable gas
  – When over 120% LEL has been detected,
    the displayed value will change to
    four rising arrows, tone of audible alarm will change
    and a flashing message will be shown
  – The instrument must be returned to a gas free area
    and switched off by a press of both buttons together. A timer from 10
    to zero will appear with the messages below alternating
Alarms (7)

• Default Alarm Settings (Table 1)
Alarms (8)

• Man Down Alarm (Motion sensor) - October onwards
  – Protects the user from danger in event of becoming unconscious or
    unable to move.
  – When the instrument has not detected a movement for a pre-set period
    of time, the displayed back-light will flash red, the audible alarm will
    sound every two seconds and the red LED’s will flash




  – The Man Down Alarm is latching and can only be acknowledged after
    the instrument has moved.
Confidence signal

• During normal operation, the instrument sounds a
  confidence beep and illuminates the green LEDs
  briefly every 15 seconds.

• This function makes the user
  aware that the instrument is
  working correctly and alarms
  are functioning.
Self-Test
• Self-Testing the PS200
  – Press & hold the LH button
  – The following screens will be shown successively




  – The alarms will be activated for a brief period
  – Followed by the flammable cal gas being shown
Fault warnings

• Low Battery
  – ‘LOW BATTERY’ flashes approximately 30 minutes
    operating time remains. The display flashes red,
    the audible alarm sounds once every 2 seconds and
    the red LED’s flash.

  – ‘BAT FAULT’ flashes when approximately 3 minutes operating time
    remains. The display will be red, the audible alarm sounds
    continuously and the red LED’s remain on. After approximately 3
    minutes the instrument automatically switches off.
Battery life

• Battery life varies depending on instrument
  configuration
   – Electrochemical sensors only
   – LEL sensor included
   – Pump included
Fault warnings (2)

• ZERO FAULT
  – Appears after warm-up if the instrument is switched on in gas or the
    instrument has been unable to zero all sensors. The display will be
    red, the audible alarm sounds once every 2 seconds, and the red
    LED’s flash (start-up only).
  – The instrument can still be used to detect and alarm on the other
    sensor(s) fitted.
  – Press the RH button, as per the screen prompt, to continue. A flashing
    spanner symbol will be displayed against the faulty sensor.
  – To clear, the instrument should be taken into a gas free area, switched
    off and then back on.
Fault warnings (3)

• There are 3 types of sensor fault
  – If a flashing    symbol is alternating with a gas value,
    leave instrument on for 30 minutes.
    Switch instrument Off and On again in fresh air.
    If the fault remains, return instrument to a
    GMI approved Service/Repair facility.
  – If a     symbol is displayed constantly,
    then the sensor may require replacement.
    Return instrument to a
    GMI approved Service/Repair facility.
Fault warnings (4)

• FLOW FAULT (pumped instruments only)
  – The pump symbol on the display will change and FLOW FAULT
    flashes to indicate a sample fault

        MANUAL BUMP-TEST MODE
               Objectives



• Convey a clear understanding of the
  bump-test features of the instrument
• Teach users how to test their
  instrument and know it is safe
• Train trainees to become trainers
Bump-Test mode:Switching On

• Hold the LH button to switch the instrument on in
  Bump-Test mode
• The display will flash Bump Test
  along the top of the screen




• Wait for the warm-up to complete
• Accept any messages
  during warm-up
Bump-Test mode: Apply gas

• After completion of warm-up, the screen will prompt
  the user to start applying gas.
Bump-Test mode: Gas application (LEL)

• If the LEL being applied peaks within the pre-set
  limits, within the given time period, a check mark will
  appear in front of the range, intermittent with the
  actual value.




• If the pre-set higher limit is overshot, the bump-test
  will fail.
Bump-Test mode: Gas application (O2)

• If the O2 test-gas being applied causes the oxygen
  reading to dip within the pre-set limits, within the
  given time period, a check mark will appear in front
  of the range, intermittent with the actual value.




• If the pre-set lower limit is not reached, the bump-
  test will fail.
• The back-light turns red and a cross is shown in front
  of the range.
Bump-Test mode: Gas application (toxic)

• It is possible that this was done in combination with
  the LEL, in form of a combi-gas (or mixed gas).
• If the toxic gases being applied peak within the pre-
  set limits, within the given time period, a check mark
  will appear in front of the range, intermittent with the
  actual value.



• If the pre-set higher limit is overshot,
  the bump-test will fail.
Bump-Test mode: Timed out

• If the gas application is not completed within a pre-
  set time, the instrument will time out.
• The screen shows all ranges that were not bumped
  with a spanner and the back-light turns red.
Bump-Test mode: Confirm Alarms

• After the gas application is completed, gas is
  disconnected and switched off, the user is asked to
  confirm that both audible and visual alarms were
  activated and detectable.



• Press the LH button for NO
• Press the RH button for YES
Bump-Test mode: Confirm Alarms

• After the alarms are confirmed (or not), the overall
  result for the Bump-Test will be shown.




• After, the instrument proceeds to
  normal operation:
