USER HANDBOOK

2.3 Operating Modes

Conned Space Monitor (CSM) Operation

In this mode the instrument operates as a safety monitor
for use when entering confined spaces which may

contain hazardous gas mixtures (ammable, toxic and/or

asphyxiant). The instrument continually samples the ambient
atmosphere to which the operator is exposed and generates

alarms for low oxygen, high oxygen, high ammable gas,

high toxic gas, Short Term TWA (STEL) and Long Term
TWA (LTEL).

During normal operation in CSM mode, the instrument

emits a condence beep and illuminates a pair of red LED’s
briey every 8 seconds. This function is programmable in

the instrument setup software.

The condence signal function makes the user aware that

the instrument is sensing for gas without the need for the
operator to constantly view the display:

The condence beep and / or LED indication can be disabled.

Combustible Gas Indicator (CGI) Operation

In this mode the instrument operates as a gas indicator
drawing a sample via a probe from points where gas is
suspected to be present. Alarms are disabled in CGI mode
as the instrument is generally used for measuring gas levels
rather than monitoring for the presence of gas.

2-6

GENERAL INFORMATION

2.4 Alarms

The SHIPSURVEYOR alarms are disabled in Combustible

Gas Indicator (CGI) mode. When operating in Conned

Space Monitor (CSM) mode, both audible and visual alarms

are active, (refer to Conned Space Monitor Operation in

Chapter 3). The audible alarm is rated at 85 dB(A). The

visual alarm consists of two (2) pairs of red LED’s ashing

alternately in the display panel.

The instrument, by default, will have alarm levels pre-set,

(refer to ‘Default Alarms’ table in Chapter 4).

It is the responsibility of the user to ensure that the alarm
levels, where set in the instrument, are appropriate for

the safe operation and legal requirements for the country
/ industry in which the unit is being used.

Latching alarms can only be cleared manually after the
detected gas level has fallen below the alarm limit.

An option allows the alarms to be non-latching. These clear
automatically when the gas levels fall below the alarm limit.
Another option allows the audible alarm to be muted.

TWA alarms, by default, are non-latching.

2.5 Datalogging

The SHIPSURVEYOR memory can store over 1000 logged
entries in date order. The memory will overwrite entries in

the event of an overow.

The instrument, by default, has automatic and manual
datalogging enabled when operating in CSM mode. Manual
datalogging allows the user to store a snapshot of the gas
readings at any time.

When the instrument is operating in CGI mode, only manual
datalogging is enabled. There is no automatic datalogging
available in this mode.

USER HANDBOOK

Alarm levels 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 are user congurable.

All gas ranges can have alarm limits that trigger the alarm if
the measured gas reading exceeds the set level. If a preset
alarm level is exceeded, the audible alarm sounds, the LED’s
ash, and the gas range name alternates with the alarm type.

Note: Alarms are disabled in Combustible Gas Indicator

(CGI) mode.

4.1.1 FLAMMABLE (LEL) ALARMS

Note: A congurable option allows the instrument to display
this range type as LFL (Lower Flammable Limit).

Two (2) instantaneous alarm levels (Hi and HiHi) are
congurable, each with different alarm indications, refer
to Fig. 4-1. Both are rising alarms, i.e. if the detected gas
concentration rises above the specic alarm level, the alarm
is triggered. All alarms are user congurable to meet the
needs of different companies.

4.1.2 OXYGEN (O2) ALARMS

Three (3) instantaneous alarm levels (HiHi, Lo and LoLo) are
congurable, each with different alarm indications, refer to
Fig. 4-1. These consist of one rising, and two falling alarms
(necessary to trigger alarms in oxygen decient scenarios).
All alarms are user congurable to meet the needs of different
companies.

to Fig. 4-1. Both are rising alarms, i.e. if the detected gas
concentration rises above the specic alarm level, the alarm
is triggered. All alarms are user congurable to meet the
needs of different companies.

Additionally, two (2) Time Weighted Average (TWA) alarm
levels (STEL and LTEL) are configurable with alarm
indications, refer to Fig. 4-1.

Two (2) TWA alarms are congurable for each toxic range

within the instrument.

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

average gas level over a specic period. The Short
Term Exposure Limit (STEL) is 15 minutes and the
Long Term Exposure Limit (LTEL) is 8 hours. The time
weighted averages are averaged over a full 24 hour
period whether the instrument is ON or OFF. Such

averaging essentially makes the instrument single

user applicable.

The option is available to restart the averaging after

each instrument switch-off, thus allowing for multiple

user application.

USER HANDBOOK

4.2 Alarm Types

4.2.1 LATCHING / NON-LATCHING

Each alarm can be latching or non-latching.

Latching alarms can only be cleared by the user when the
gas level returns to within the alarm limits. A latching alarm
cannot be muted.

Non-latching alarms clear automatically when the gas level
returns to within the alarm limits. A non-latching alarm can

be muted.

4.2.2 MUTING / ACKNOWLEDGING

Muting of an alarm is achieved by a press and hold of the
Bottom Button. Muting means that the audible alarm is
cancelled. The audible alarm is reactivated if a new alarm
occurs.

Acknowledging is only applicable to latching alarms and
allows audible / visual alarms to be cancelled after the gas
readings have returned to safe concentrations.

4.3 Default Alarm Settings

CALIBRATION

The instrument has been calibrated for a particular ammable

gas mixture. Where any doubt exists, the instrument should
be returned to GMI or an authorised distributor for calibration.

Three methods of calibration are possible:

• Field Calibration.

• Manual or Automatic Calibration using exiCal Plus
software CD-ROM (GMI Part No. 99553). CD-ROM

includes user instructions.

• The GMI Instrument Management System (IMS)
provides all the facilities of Automatic Calibration
with the added feature of instrument database
management.

Note: The calibration systems above (hardware and

software) are manufactured by GMI. For more details

contact GMI or an authorised distributor.

6-1

USER HANDBOOK

6.1 Calibration Validity

Calibration validity is 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 may dictate shorter periods.

Regular checking establishes a pattern of reliability and

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

with operational experience. The higher the risk, the more
frequently calibration should be checked.
