Exposing the sensor to high concentrations of flammable gas above the LEL can cause damage to the sensor and inhibit its proper operation. The PS 200 has an in-built safety alarm feature to prevent this.6
7Press and Hold Right Hand Button for 1 second Switching ONPress and Hold Right Hand Button for 1 secondInstrument begins warm-up routine with the GMI and PS200 logo.During 30 second warm-up a countdown timer appears on the screenThe instrument display identifies the serial number, software version, datalogging, battery status and flammable cal gas during warm-up.NOTE: The display back-light illuminates and remains on during warm-up. When warm-up is completed, the screen light automatically switches off.Battery StatusThe battery status displayed during warm-up indicates battery condition with a bar graph showing Full, 75%, 50% and 25% capacity.7
8The time and date from the instrument’s built-in clock is displayed Warm-up informationThe time and date from the instrument’s built-in clock is displayedThe calibration due date is shown on the displayIf the calibration due date has expired, the audible and visual alarm activatesPress RH Button once to acknowledge overdue calibration due date, cancel alarms and continue with warm-upFor datalogging, the time and date is set from this clock. This will be important when viewing the logged data.Calibration Due DateThe calibration due date appears on the screen.A configurable option is available not to display this screen.If the calibration due date has expired, an audible and visual alarm is activated.To acknowledge the calibration due date is overdue, press the RH button. This cancels the alarms and continues to the next screen.Configurable options exist to either:not to display the calibration overdue screenautomatically proceed to next screen when overdueprompts user to switch-off the instrument when overdue8
9Warm-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.9
10When sensors are zeroed correctly a tick appears next to each sensor Sensor checkA diamond symbol appears next to each sensor to confirm that the sensoris working correctlyis being zeroedWhen sensors are zeroed correctly a tick appears next to each sensor10
11Zero faultIf 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.Sensor Check FailureThe instrument display will show a spanner symbol against a sensor which fails the zero check during warm-up. The warm-up routine will pause until the user has accepted the condition by acknowledging the alarm. This clears the audible / visual alarm and allows the warm-up to continue.When a zero check failure has been acknowledged the display will show a flashing spanner alternating with faulty sensor zero reading.A configurable option is available to force the user to switch the instrument off if a zero fault is detected.NOTE: If a sensor fault is detected during normal operation of the instrument, an audible / visual alarm is activated immediately and the spanner symbol is shown adjacent to the faulty sensor type in the display.11
12Normal operating display When warm-up is completed successfully, back-light switches off and normal operating screen is shown as followsEach gas range is displayedDisplay back-light can be manually switched on with a single press of the RH button. It remains on for 20 seconds and then switches offThe normal operating display is shown after the instrument has successfully completed the warm-up. Each gas the instrument is configured to measure is shown (in this example LEL, O2, H2S and CO) along with battery status.The instrument can be set up to display a simple ‘OK’ message.The display light automatically switches off after warm-up. It can be manually switched on when surveying in poor lighting conditions with a single press of the RH button. It remains on for 20 seconds and then automatically switches off.12
13Normal 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.13
14Viewing 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 secondsThe instrument records the maximum and minimum gas values for each sensor, since switch-on.To view max / min values, proceed as follows:start from normal operating display, press the RH button once to switch the screen light onpress the RH button again, while the screen light is on, to view the maximum gas values stored in the instrument. The example shows maximum values in a 4 gas instrument: LEL, O2, CO and H2Spress the RH button again to view the minimum values stored in the instrument.After these readings have been noted, they can be removed from the memory by pressing and holding the RH button for 2 seconds. This will return the instrument to the normal operating screen. The display returns to the normal operating display if no button is pressed.14
15Remote sampling / pre-entry check Remote sampling is carried out with the in-built electric pump or by the hand aspiratorPress 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 is carried out with the in-built electric diaphragm pump option, or by the hand aspirator for non-reactive gases.On pumped models the pump is off after start-up.NOTE: It is only possible to turn the pump ON / OFF when no alarms are present on the instrument.Warning (Hand aspirator) : The PS 200 is primarily designed to be used with a built-in pump for remote sampling. The aspirator can be used for indicative sampling but it mist be noted that a reading error of +/- 20% is possible. In addition, whereas the pump can sample quickly and accurately with up to 30m of sample line, the aspirator must only be used with up to 10m and the sample time extended.15
16Push quick connector on to the inlet nozzle Attach tubingRemote samplingTygon tubing with ID of 4mm is used in combination with the bayonet connectorPush quick connector on to the inlet nozzleTurn clockwise until locked in placeIt is important that the instrument is switched off when charging a battery.The battery can be recharged using the standard battery charger as shown, or using the vehicle charger.NOTE 1: The battery should only be recharged using GMI parts.NOTE 2: When the battery is recharging, the screen will indicate ‘charging’. Once the battery is full, the screen will indicate ‘charged’.the outer 2 red LED’s illuminate for a period of 14 hours, after which are replaced by green LED’s. This is a timer function only, not an indication of the charged condition of a battery.16
17AlarmsAll gas ranges have alarm limits that trigger an alarm when the measured value exceeds the set levelThe audible alarm sounds, LEDs flash red, the instrument vibrates and the gas range in alarm flashes on the displayFlammable LEL Alarm Limits - Up to 2 alarm levels are programmableOver-Range Flammable Gas Alarm - If the flammable gas readings exceed 120% LEL, a safety alarm is activatedOxygen Alarm Limits - Up to 1 upper and 2 lower alarm limits are programmableToxic Alarm Limits - Up to 2 instantaneous and 2 Time Weighted Average (TWA) alarms are programmable for each toxic rangeNOTE: A Time Weighted Average value is the mean average gas level over a specific period. The STEL is 15 minutes and LTEL is 8 hours. UK legislation requires the TWAs to be averaged over a 24 hour period whether the instrument is On or Off. Such averaging essentially makes the instrument single user applicable. An option is to restart the averaging at each switch-off, allowing for multiple user application.17
18The instrument display will signal the range in alarm. Alarms (2)The instrument display will signal the range in alarm.Example of Lo Lo Oxygen Alarm DisplayExample of HiHi LEL Alarm DisplayIn the 1st example the Lo Lo Oxygen Alarm is activated. 2 lower alarm limits are programmable in the oxygen range, these could be 19% and 18%. This display shows the instrument having measured an oxygen level below the 2nd of the low alarm limits.In the 2nd example the HI HI LEL Alarm is activated. Typically, the HI HI LEL would be set at 20%, a 2nd higher limit can be set if required.18
19Alarms 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 limitsNon-Latching - the audible and visual alarm will reset automatically when the reading returns to within the pre-set alarm limits19
20Acknowledging 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 disabledOnce in a gas free area, or the gas reading has returned to within pre-set limits, a press and hold of the RH button will silence / mute the sounder and extinguish the LED’s.Mute Enabled in set-up - silences alarm for 60 secondsMute Disabled in set-up - cannot silence alarm until gas falls below alarm levelAcknowledging Gas Alarms depends on the set up configuration of these alarms. PS 200 has a totally flexible set-up to conform to the user required for latching, non-latching, mute enabled, disabled. Please refer to your individual company guidelines regarding gas alarms.20
21Alarms (5) Muting Gas Alarms Alarms can have the mute function enabled or disabledThis 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).Once in a gas free area, or the gas reading has returned to within pre-set limits, a press and hold of the RH button will silence / mute the sounder and extinguish the LED’s.Mute Enabled in set-up - silences alarm for 60 secondsMute Disabled in set-up - cannot silence alarm until gas falls below alarm levelAcknowledging Gas Alarms depends on the set up configuration of these alarms. PS 200 has a totally flexible set-up to conform to the user required for latching, non-latching, mute enabled, disabled. Please refer to your individual company guidelines regarding gas alarms.21
22High 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 gasWhen 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 shownThe 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 alternatingThe high flammable gas over-range alarm is designed to protect the user from danger. It is also worth noting that exposing the LEL sensor to concentrations of flammable gas above 100% LEL can damage the sensor.NOTE: To avoid accidental switch off in a dangerous state, the off cycle is increased to 10 seconds22
23Default Alarm Settings (Table 1) Table (1) details the default setting for each alarm when configured initially.Each alarm has a default setting when configured initially. These are outlined in the table.EH40 regulations are shown.An option is to change these settings where required.23
24Man Down Alarm (Motion sensor) - October onwards Alarms (8)Man Down Alarm (Motion sensor) - October onwardsProtects 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 flashThe Man Down Alarm is latching and can only be acknowledged after the instrument has moved.The Man Down Alarm, governed by the motion sensor, is not normally on, but can be configured to be on always, or select at every start-up.This alarm is not triggered by any gas level, but rather the lack of movement of the instrument, and thus the user it pertains to.24
25Confidence signalDuring 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.The confidence beep and / or LEDs can be disabled if required.25
26Press & hold the LH button Self-TestSelf-Testing the PS200Press & hold the LH buttonThe following screens will be shown successivelyThe alarms will be activated for a brief periodFollowed by the flammable cal gas being shownIt is important that the instrument is switched off when charging a battery.The battery can be recharged using the standard battery charger as shown, or using the vehicle charger.NOTE 1: The battery should only be recharged using GMI parts.NOTE 2: When the battery is recharging, the screen will indicate ‘charging’. Once the battery is full, the screen will indicate ‘charged’.the outer 2 red LED’s illuminate for a period of 14 hours, after which are replaced by green LED’s. This is a timer function only, not an indication of the charged condition of a battery.26
27Fault 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.NOTE: Both audible and visual gas alarms continue to operate after the low battery warning message appears.27

29Fault 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.A Zero Error is caused by switching the instrument on in the presence of gas or if the instrument has been unable to zero all the sensors correctly.It is strongly recommended that the instrument is returned to a gas free area. Switch the instrument off and then switch on again in clean air. If the fault persists, return the instrument for service.The instrument can still be used to detect and alarm on the other sensors fitted. At the screen prompt a press of the RH button will allow the warm-up to continue.The faulty sensor will cause the instrument to display a flashing spanner symbol, alternating with the faulty sensor reading (only in LEL range), to warn the user that this sensor is not working correctly.A configurable option exists to force the users to switch off, if this is detected.29
30There are 3 types of sensor fault Fault warnings (3)There are 3 types of sensor faultIf 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.30
