ADDITIONAL SAFETY DETAILS - CSA ONLY

CAUTION: Before each days Usage, test on a known concentration of methane,

equivalent to 25 - 50% of full scale concentration. Accuracy must be within
0 to +20% of actual. Accuracy may be corrected by calibration. (Refer to
Chapter 7 : ‘CALIBRATION’).

ATTENTION: Avant chaque utilisation journalière, testez la réaction de l’appareil
en utilisant une concentration connue en méthane, correspondant à 25-50%
de la lecture à fond d’échelle. La précision doit se situer entre 0 et +20% de la
valeur réelle. La précision peut se corriger en étalonnant l’appareil (voir Chapitre
7 : CALIBRATION).

CAUTION: Any rapid up-scale readings followed by a declining or erratic reading
may indicate a gas concentration beyond the upper scale limit, which may be
hazardous.

ATTENTION: Toute lecture dépassant rapidement le maximum de l’échelle et
suivie par une diminution ou une lecture erronée, indique une concentration de
gaz supérieure à la valeur maximale de cette échelle. Cette lecture n’est pas

signicative.

CAUTION: Substitution of components may impair intrinsic safety.
ATTENTION: le remplacement d’un composant peut porter atteinte à la sécurité

intrinsèque du produit.

CAUTION: Do not charge in a hazardous area. Um = 6V.

COPYRIGHT

NOTE : CSA a seulement évalué la partie LIE pour la mesure des performances

en détection de gaz inammables.

NOTE: The instrument contains internal checking of sensor sensitivity, which during
calibration will prevent the sensor being calibrated if it has been contaminated
or reached its end of life. In addition to this the Instrument Management System
(IMS) can be used to track the condition of sensors from stored calibration results.

AREAS OF USE

Exposure to certain chemicals can result in a loss of sensitivity of the ammable

sensor. Where such environments are known or suspected it is recommended that
more frequent response checks are carried out. (Refer to Chapter 3: ‘MANUAL
BUMP TEST’). Chemical compounds that can cause loss of sensitivity include
Silicones, Lead, Halogens and Sulphur.

Do not use instrument in potentially hazardous atmospheres containing greater

than 21% Oxygen.

SPECIAL CONDITIONS OF USE

No precautions against electrostatic discharge are necessary for portable
equipment that has an enclosure made of plastic, metal or a combination of the

two, except where a signicant static generating mechanism has been identied.

Activities such as placing the item in a pocket or on a belt, operating a keypad

or cleaning with a damp cloth, do not present a signicant electrostatic risk.
However, where a static-generating mechanism is identied, such as repeated

brushing against clothing, then suitable precautions shall be taken, e.g. the use
of anti-static footwear.

STORAGE, HANDLING AND TRANSIT

The instrument is designed to handle harsh environments. The instrument is
sealed to IP67 and, if not subjected to misuse or malicious damage, will provide
many years of reliable service.

INTRODUCTION

1.1 GENERAL DESCRIPTION

The GMI PS200 series combines quality, ruggedness and
advanced technology in a user friendly, portable gas detector.
It is compact, lightweight, water resistant, extremely robust

and is suitably certied to recognised International Standards.

The PS200 is designed for conned space monitoring, for

example, in sewers, underground piping, or within tanks and
other personal monitoring applications. With audible, visual
and vibrating alarms, it provides early warning of dangerous
gas levels.

The instrument is available as either a pumped or diffusion
model and is powered by an internal Li-ion (lithium ion)
rechargeable battery with an operating time of up to 80 hours
for non-pumped operation (20 hours for pumped operation).
Operating time is sensor dependent. Maximum recharge
time is 4 hours.

Operated via two push buttons, this instrument provides the
user with a simple to use, yet state-of-the-art, gas detector.
(Fig. 1-1).

The PS200 series features high visibility LED’s, a display that
changes colour from green to red when an alarm is present,
a sounder with a 90dB minimum output and a vibrating

alarm. Users can be condent that, should gas levels exceed
congured threshold limits or a sensor / ow / battery fault

exists, a clear and unmistakeable indication is evident.

Latching, (i.e. alarm will stay on until the user resets by a

press and hold of the Right Hand (RH) button when
the gas reading has returned within the preset alarm limits),

or Non-Latching (i.e. the audible and visual alarm will reset
automatically when the reading returns within the preset alarm
limits). Refer to Alarms Table, Chapter 4, for individual alarms.

Note: Default alarms are set in accordance with current
international standards.

The audible alarm on each pre-set alarm can be muted for a
period of 60 seconds by a press and hold of the Right Hand

(RH) button . After this period, should the gas value
remain outwith the pre-set alarm limit, the non-latching audible

alarm will become active again. If latching, the audible alarm
will become active again regardless of gas value.

2.7 REMOTE SAMPLING (with pump option)

Remote sensing is possible with the internal electric pump
option, or by using a hand aspirator. Connect the sample
line to the sample connector at the bottom of the instrument.

On pumped models, the pump is OFF after start-up.

Warning (Hand Aspirator): The PS200 Series is designed
to be used with a built-in pump for remote sampling. A
hand aspirator can be used for indicative sampling, but it
must be noted that when using a hand aspirator, a reading
error in the region of + 20% is possible. In addition,
whereas the pump can sample quickly and accurately with
up to 30 metres of sample line, the hand aspirator must
only be used with up to 10 metres of sample line and the
sample time is extended. The sample line must be intact
and the proper ow established.

2.7.1 Pump Operation:

Press and hold the Right Hand (RH) button to start or
stop the pump.

MANUAL BUMP TEST OPTIONS

3.1 BACKGROUND

A bump test veries sensor response and alarm operation
by exposing the instrument to a known concentration of gas.
The PS200 series of instruments can be bump tested either
manually or automatically (using the Auto Bump / Calibration
Station).

This chapter describes the manual bump test options that
validate either the alarm operation (quick bump), or both alarm
operation and sensor response (full bump). By default, both
of these options are disabled.

To facilitate manual bump testing, a test kit (Part No. 64051)
is available and contains the necessary test gas, regulator
and Tygon® tubing to ensure a proper bump test is performed.

CAUTION: When performing a bump test, the

test gas concentration should be high
enough to trigger the instrument’s
alarms. Should any instrument fail a
bump test, then a full calibration must
be performed.
A Quick bump test only checks the
operation of the audible and visual
alarms and does not validate sensor
accuracy or response time.

3-1

USER HANDBOOK

3.2 MANUAL BUMP OPTIONS

The PS200 series provides two bump test options, QUICK
and FULL.

The QUICK bump test validates that the alarm threshold has
been exceeded for each range.

The FULL bump test checks the response of all ranges against
set limits.

By default, both of these options are disabled.

3.3 INITIATING A MANUAL BUMP TEST

ALARMS

4.1.1 Flammable LEL Alarm Limit

Two alarm levels, ‘HI’ and ‘HIHI’, are available, each with

different pitch and tone. All alarms are user congurable to
meet the specic needs of different companies.

4.1.2 Over-Range Flammable Gas Alarm Function

The ammable sensor is designed for use in the LEL range
only. Exposure to high concentrations of ammable gas,
such as lighter fuel, can damage the ammable sensor. If the
ammable gas readings exceed 100% LEL, a safety alarm

will be activated. The instrument should then be switched OFF
and returned to fresh air.

4.1.3 Oxygen (O2) Alarm Limits

Three alarm levels, ‘HIHI’, ‘LO’ and ‘LOLO’ are available, each

with different pitch and tone. All alarms are user congurable
to meet the specic needs of the end user.

4.1.4 Toxic Alarm Limits

When operating normally, the instrument calculates the Short
Term Exposure Limit (STEL) and Long Term Exposure Limit
(LTEL), known as Time Weighted Average (TWA) readings, for
each toxic gas range alarm. TWA alarms are programmable

for each toxic range tted to the instrument. Additionally, two

alarm levels ‘HI’ and ‘HIHI’ are available.

Note: A Time Weighted Average (TWA) value is the mean

average gas level over a specic period. The STEL is 15

minutes and the LTEL is 8 hours. Typically, TWA alarms make
the instrument single user applicable. An option is available

to restart the averaging after each instrument switch-off, thus
allowing for multiple user application.

4-3

USER HANDBOOK

Note: The toxic gas alarm levels – instantaneous, STEL
and LTEL are set at the time of instrument manufacture.
It is important that the user ensures that the levels are in
accordance with their company’s alarm levels and with health
and safety legislation. The alarm levels may be changed, if
required, via the instrument set up menu.

In the following examples, Fig. 4-1 illustrates a 4-gas
instrument signalling a ‘LOLO’ Oxygen alarm and Fig. 4.2
shows a 4-gas instrument signalling a ‘HIHI’ LEL alarm. If more

than one gas alarm level is exceeded, the gas value will ash

for each gas type in alarm.

the alarm level.

If alarm conguration allows muting of audible alarm, the
following applies:

Non-latching: Once alarm has been muted, the audible

alarm is cancelled for a period of 60 seconds, and if gas

concentration during that time falls below alarm set point, the
visual alarm clears automatically.

Latching: If audible alarm has been muted and if gas
concentration during that time falls below alarm set point,
visual alarm requires to be acknowledged to clear.

4.4 HIGH FLAMMABLE GAS OVER-RANGE ALARM

Caution: Exposing the LEL sensor to concentrations of

ammable gas above 100% LEL can damage

the sensor.

In order to protect the user from danger in the event of the

ammable gas (LEL) sensor being over exposed to a high
concentration of ammable gas, the instrument has an over-

range alarm.

bays, it is recommended that the instrument is switched OFF,
the ‘alligator clip’ is in the closed position and the ‘belt hook’
is upright.

Install the instrument in one of the vacant charging bays
making sure that the locating tongue engages in corresponding

slot in the base of the instrument and ensuring that the

instrument is rmly seated in charging unit.

Charging is fully automated.

Instrument(s) can remain installed in the charger after charging
is complete.

The 12V to 24V DC USB In-Vehicle Charging Adaptor (Part
No. 64248), as illustrated in Fig. 6-3, is designed to provide
the GMI PS200 series instrument with corrected power for
battery charging. The power transformer is a switch mode dc
transformer operating from a 12 to 24 volt dc supply.

Fig. 6-3 In-Vehicle Charging Adaptor

The Charging / Comms clip (Part No. 64260), supplied with
the instrument, is connected to the base of the instrument as
illustrated in Fig. 6-4. The mini-USB plug from the charging
cable (supplied with Part No. 64247 Mains Adaptor) is then
connected to the clip. The standard USB plug can now be
connected directly into the USB socket on the USB Charging
Adaptor. With all connections in place, insert the adaptor into
the vehicle accessory socket. A red LED on the front of the
USB Charging Adaptor indicates ‘power ON’.

Note:

1. The charging adaptor is designed to fit a standard

accessory socket that may vary in size in certain vehicle
types. Always ensure that you use a proper tting socket.

2. Some vehicle types and models do not provide power to

the accessory socket when the vehicle ignition is switched
off. Charging will only take place when the accessory
socket is powered. A red LED on the charging adaptor
indicates that power is ON.

3. Care should be taken not to leave the instrument on
charge for excessive periods when the vehicle ignition
is switched off as this will reduce the battery power of
the vehicle.

CALIBRATION

7.1 GENERAL DESCRIPTION

The instrument has been calibrated for particular gases.
Where any doubt exists the product should be returned to
GMI or an authorised distributor for calibration.

WARNING: The instrument must be calibrated and

congured by authorised personnel only.

Three methods of calibration are possible:

• Field Calibration.

• Manual Calibration using flexiCal Plus software
CD-ROM (Part No. 99553). CD-ROM includes user
instructions.

• Automatic Calibration. The GMI Automatic Bump /
Calibration Station (Part No. 64052 / 64052Q), shown in
Fig. 7.1, provides controlled delivery of gases permitting
users to bump test and calibrate the instrument in
a controlled manner whilst maintaining a record of
calibration results on a PC.

Note: The detailed calibration methods, consisting of
both hardware and software, are manufactured by GMI.
For further details contact GMI or an authorised distributor.

USER HANDBOOK

Fig. 7-1 PS200 Auto / Bump Calibration Station

7.2 CALIBRATION VALIDITY

Calibration validity remains the responsibility of the user.
Under normal operating conditions a 12 month period can
be expected. This is no guarantee, however, as the precise
application of the product is unknown to GMI. Individual codes
of practice will dictate shorter periods.

Regular calibration establishes a pattern of reliability and

enables the calibration check period to be modied in line with

operational experience. As a guide, the higher the risk, the
more frequently calibration should be checked.
