Overview Single button user operation Robust rubber overmould LCD with bi-colour backlight Up to 4-gases Audible/visual/vibrating alarms Integrated Bump-Test feature Datalogging included Optional integral pump
-20°C Ta 50 ° C ATEX: Sira 11ATEX2041X II2G Ex ia d IIC T4 Gb IECEx: SIR X UL*: 913 (7th Edition) MED*: => A.1 / 3.30 CSA*: C22.2 No 152 Certification *pending
Operating procedures Check the following before use: instrument is clean and in good condition hydrophobic and inlet filter are clean and in good condition sample line and probe, if used, are in good condition Switch ON in fresh air battery is fully charged instrument is within the calibration period all gas ranges are operational and the instrument is zeroed Perform leak check by blocking inlet of sample intake
Switching ON Press and Hold Right Hand Button for 1 second Instrument begins warm-up routine with the GMI and PS200 logo. During 30 second warm-up a countdown timer appears on the screen The instrument display identifies the serial number, software version, datalogging, battery status and flammable cal gas during warm-up.
Warm-up information The time and date from the instrument’s built-in clock is displayed The calibration due date is shown on the display If the calibration due date has expired, the audible and visual alarm activates Press RH Button once to acknowledge overdue calibration due date, cancel alarms and continue with warm-up
Warm-up information (2) If the calibration is overdue, and the instrument is configured to be switched off in that situation, the 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.
Viewing Max & Min values Start from normal operating screen. 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.
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 Attach tubing
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-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 Self-Test
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 –The display will be red, the audible alarm sounds continuously and the red LED’s remain on. –Check sample line / filters / and probe for blockage. –Clear the blockage and restart the pump by a press and hold of the RH Button
Switching off Press and hold the LH and RH button together to switch the instrument off. The instrument will start a countdown from three (3) to OFF. Both buttons must be pressed together until the display goes blank. While both buttons are pressed, the audible alarm sounds to alert the user that the instrument is switching OFF.
Recharge (Li-ion) Battery –Connect standard charger lead to battery pack –Switch on power supply to the charger –Leave up to 4 hours to recharge the discharged battery pack from depleted Charging
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:
Bump-Test mode: Quick Operates the same as the full bump-test, but does not have upper limits and uses alarm level as lower limit.
Datalogging The instrument comes by default with datalogging. Automatic logging is set for every minute; this can be changed. Manual logging is available by pressing the LH button. Briefly, the word ‘LOGGING’ is shown. A manual log is clearly identified in the datalogging software.
