USER HANDBOOK

2.3 Operating Modes

Confined 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 (flammable, 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 flammable gas, high toxic gas, Short Term TWA (STEL) and Long Term

TWA (LTEL).

During normal operation in CSM mode, the instrument emits a confidence beep and illuminates a pair of red LED’s briefly every 8 seconds. This function is programmable in the instrument setup software.

The confidence 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 confidence 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 Confined

Space Monitor (CSM) mode, both audible and visual alarms are active, (refer to Confined 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 flashing 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 thesafeoperationandlegalrequirementsforthecountry / 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 overflow.

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.

2-7

USER HANDBOOK

2.5.1 Location (LOC) Selector

The SHIPSURVEYOR instrument features a ‘LOC’ location selector, allowing the user to allocate datalogged readings to a location (LOC) of a vessel. Refer to Chapter 3.18 for more details.

2.6 Max / Min Values

The SHIPSURVEYOR instrument records the maximum / minimum gas values for each sensor, since switch-on.

2.7 Construction

The instrument is housed in a tough, impact resistant, moulded case made of polypropylene.

The top panel features a carbon loaded polycarbonate LCD cover.

The battery cover is attached to the main instrument body by means of two stainless steel hexagonal screws.

The instrument is sealed against dust and water to IP54 standard. The instrument sensors are protected from dust and water by an integral hydrophobic filter.
