1. INTRODUCTION

The TQ4400 Pump room sampling system is a multipoint, sequential, aspirated, gas

sampling system. The System is designed to meet with IMO / SOLAS requirements,

and comply with classification rules for monitoring Void Spaces on board Gas

Carriers and Oil & Gas Tankers, in areas adjacent to the cargo areas.

The TQ4400 Pump room sampling system extracts a gas sample from a desired

location, via transport lines to an analysing unit where the sample is monitored for

Flammable, Toxic and Oxygen gases. The TQ4400 in its usual form uses fixed

gas sensor heads to constantly monitor gases in conjunction with solenoids and a

pump to make this into a cost effective sampling system.

** The TQ4400 Pump room sampling system should not be regarded as a primary

unit for the safety of the personnel within the Pump room. Portable personal hand

held devices are recommended as primary protection for personnel in confined spaces.

**

The number of locations for a TQ4400 is restricted to 8. Any more, then the TQ 4400

Ballast tank monitoring system should be used

Typical explosive and toxic gas sensors, which can be installed within the TQ4400,

can be seen in table 1, (other gases are available on request.)

Explosive Toxic

Methane 0-100% LEL H2S Various ranges

2. SYSTEM DESCRIPTION

The TQ4400 Pump room sampling system standard Analysing Unit is housed in a

wall-mounted enclosure complete with front panel Display Unit. The enclosure

contains all electrical, electronic and pneumatic equipment required to monitor,

display, control and provide alarm outputs for the relevant locations.

The TQ4400 Pump room sampling systemis divided into the following main

components:

Pneumatics

Sensors

Control & Display Unit

Power Supply Change Over Unit

Sample Line Accessories

Outputs

Technical Specification

2.1 Pneumatics

Every Sample Line from the relevant location is firstly connected to its

respective external Shut-off Valve to provide sample line isolation. The

sample then passes through a flame arrestor mounted externally on the bottom

of the cabinet, and into the Analyser Unit.

The typical Analysing Unit contains the following pneumatic devices:

Solenoid Valves

Particulate Filter Pump

Flow Detector

Leak Detection

2.1.1 The Solenoid Valves are mounted singularly on the back panel of the

cabinet. Each solenoid is then individually plumbed to the gland plate

where they are fitted with a deflagration flame arrestor from which the

sample line can be connected.

Connected to each solenoid is a timer relay the time set on this relaygoverns the sample time. Each timer will then trigger the subsequent timer

on completion of sample, therefore resulting in a sequential sample

Each valve is complete with a 24V D.C. coil, and connection to each coil

is via a 3 pole connector containing an LED and snubbing diode.

2.1.2 The Particulate Filter is fitted with a micro-fibre filter element, which

cannot be cleaned and therefore must be replaced when it is suspected of

reducing air flow. This unit is also fitted with a poly-carbonate bowl to

allow visual inspection of the filter element. Spare filter elements can be

supplied, refer to Section 8 for Part numbers.


56/99


2.1.3 The Pump is an Industrial type to ensure adequate flow rates for the

larger installations. As an example on transport tube dimensions of

4.0mm I/D, flow rates in excess of 4 litres/min. are achievable for sample

line lengths up to 300 metres. Based on these figures, sample times for a

300 metre sample line will be in the order of 1 minute, providing sharp

bends and fittings are kept to a minimum. A Pump Service Kit can be

supplied refer to Section 8 for Part numbers

2.1.4 The Flow Meter is fitted in the sample flow line to indicate airflow to the

sensors and works in conjunction with the Sample by-pass needle valve.

The steel float, sensing ring and control relay, are all part of the flow fail

device. If the float passes down through the sensor a Low Flow signal is

sent to its control relay. When flow returns the float will raise back

through the sensor and the signal to its control relay will revert to normal.

2.1.5 A Leak Detection System is incorporated within the TQ4400 Analyser

enclosure and monitors for any accumulation of flammable gases within

the enclosure. This system utilises a TQ122 catalytic flammable gasdetector fitted in the top of the enclosure, which is connected to a

TQ126Fcontroller fitted in the Power Supply Change-over Unit.

If the gas concentration within the enclosure exceeds 30% LEL the Power

Supply Change-over Unit will disconnect the power supply to the

TQ4400Analysing Unit. The power supply cannot be re-connected until

the gas concentration has fallen below the alarm level and a manual reset

at the Power Supply Change-over Unit has been carried out.

2.1.6 Sample Line Equipment is optionally available in several forms to suitthe sample location.

End of Line filters for Dry areas,

In-line filter (where an End of line filter is not practical)

There are two types of End of Line Filters. See section 5.4 & 5.5

A fibre element type where the filter element has to be replaced

periodically.

A stainless steel type where the filter element can be cleaned.

Both of the above filters are supplied with dual compression fittings tosuit pipe sizes 6 or 8mm O/D, in either brass or stainless steel. It is

advisable to protect the Filter when installed in a location where damage

may occur.

The In-Line Filteris a stainless steel unit that is suitable for attaching to

a stop-valve when fitted in a stop valve box or can be fitted to the line in a

serviceable location. It is advisable to remove the In-Line Filter complete

for cleaning, as splitting the filter in situ may damage the threads.


57/99



2.2. Sensors

There are two type of sensors, the infrared type, for flammable gases, or the

electro-chemical type for Toxic and Oxygen gases. When a system comprises

of more than one sensor, they are connected in series in the sample line which

then is vented out from the enclosure through a flame arrestor.

2.2.1 Infrared Sensor (GD 129NI)

The operation of the infrared sensor within the TQ4400 Pump room

sampling system is to measure the absorption of infra red light by a target

hydrocarbon gas and converting that absorption to an electronic signal.

The infrared sensor is now packaged as a GD-129 stand-alone unit within

the TQ4400 and provides a 4-20mA signal for their respective target gas

concentrations.

Part Number for the GD129 for 0-100%LEL METHANE is 340-020

2.2.2 Electro-chemical Type.

These sensors typically monitor for Oxygen and Toxic gases and because

of their properties have a life span of approximately 1-2 years depending

on conditions.

The Electrochemical types, as with the Infrared sensor, provide a 4-20mA

signal for their respective gas concentrations.

Part Number for the TQ123 for 0-25%VOL OXYGEN is 123-531

Part Number for the TQ123 for 0-50PPM H2S is 123-251


58/99


2.3 Control and Display Electronics.

The settings for the TQ4400 Pump room sampling system is divided into two

Parts, a) the TQ4400 display and b) the TQ 4400 Set Up/ Control

The TQ4400 Set up/ Control monitors the signal the signal from each gas

detector in the sample system and controls the solenoids sequentially.

The TQ4400 Set up/ Control analyses the gas and transmits back to the TQ4400

display card concentrations and any alarm associated with the recent analysis of

the gas sample

down the relevant push button, and are discussed further below:

3.3.1 GOTO Channel

The user may press down and hold theRESETandHOLDbutton until thedisplay reads GOTO, the user must then release the RESETand HOLD

button. You can then select which sample location to GOTO by using

ACK to go up and RESET to go down through the sample locations.

PressingHoldselects the desired channel.

Once the unit is sampling from the desired location you can then either

HOLD, SKIP or Reverse Purge the location.

3.3.2 Hold Channel

The user may press down and hold the HOLD button until the display

readsHOLD CHANNEL, the user must then release theHOLDbutton.

CHAN 1

HOLD CHANNEL

This will invoke the Hold Channel function. The current Channel location

will be continuously sampled for a maximum period of 20 minutes after

which time the system will revert to sequential sampling. At any time the

user may release the channel and enable the system to revert back to

sequential sampling.

This is achieved by pressing down and holding theHOLDbutton until the

display readsRELEASE CHANNEL, the user must then release theHOLD

button.

FLOW FAIL

To clear the Fault condition press clear blockage or SKIP the channel,

then hold the RESETbutton until the display reads RESET ALARM. At

the same time, the System Healthy led will illuminate and the Fault relay

will be de-activated. The alarm will not clear until the system has flow

again, it may require re-booting to allow user to SKIP the problem

channel.

RESET ALARMS

3.4.1.3 Communications Failure

A Comms Failure will initiate when communications are interrupted for

more than 2 minutes between the Display BTC PCB and the Control BTC

PCB.

COMMS FAILURE

This cannot be reset by theRESETbutton; the panel has to be opened and

powered down and back up again. However it is preferred to do this from

the power supply changeover unit.

3.4.2 Concentration Alarms

There are two alarms on the system, a low level alarm, ALARM 1, and a

high level alarm,ALARM 2. When the gas concentration exceeds the set

levels, the appropriate alarms will be activated, and operate the

appropriate LEDs and alarm relays. The LCD will display the first

channel to be in alarm, together with the sensor gas type and relevant

alarm condition. The system will continue to sample the channels

sequentially.

ii) Turn on the gas bottle. Gas should be regulated to between 1 and 2 LPM.

iii)Turn the 3 way Valve handle 180o.

The gas concentration on the LCD will start to change after a few seconds.

If the concentration does not move then the sensor may need replacement.

Test electrically by placing voltmeter positive probe on clear (GD129) or

yellow (TQ122) wire from sensor and negative probe on Zero volts any

black wire. 0.88-0.91VDC will be a zero reading for the sensor and this willrise up to 4.8volts for the full range of the sensor, typically with respect to

4-20mA.

When gas concentration reading stops changing e.g. when the gas

concentration reading has settled, accept the reading by pressing the

SELECTbutton.

* NOTE When calibrating oxygen at 21% and a normal sample is used

for calibration please wait at least 60 seconds, as the sensor will usually

initially show over 25% and will take time to adjust for pressure differences

when the 1stsample solenoid opens.

When SELECT VALUE is displayed the user should use the UP / DOWNkeys to adjust the output reading displayed when the current gas

concentration is present at the sensor and press the SELECT button to

accept the value. These values will then be scaled and stored in the

NVRAM for future reference.

* - NOTE - If the user enters the Calibrate Sensor Menu again for the same

sensor then the system will always display its original default calibration

setting, not the new value recently adjusted. - *

H2S sensors can take a very long time to return to zero, this is due to the

gas sticking to the lining of the system pipe work. If system shows 1 2

PPM please allow a few days for it to fully return to zero.

4.6.7 Technician Sub Menu - Clear Calibration

This option allows the user to clear all calibration data from the NVRAM

and in doing so sets all sensors to default calibration.

Press SELECTto clear calibration.
