1 INTRODUCTION
This variant of the manual is specifically for the FGD14 fitted with a Premier Infrared
sensor.
The FGD14 is a self-contained unit designed to detect environmental conditions by
fitting suitable sensors. It also provides the user with local and remote indication of
alarm / fault conditions.
The FGD14 can be fitted with a display unit that allows non-intrusive calibration /
configuration via concealed push buttons and local readout of gas levels.
A remote keypad can be temporarily fitted to gain access to the calibration /
configuration data when the unit is supplied without a display.
The FGD14 is fitted with two relays, which are linked to user definable alarm set
points.
The FGD14 may be connected to an interface unit that will allow direct connection to
a PC.
1.1 Sensors
This variant is fitted with a CO2 Premier infrared sensor. The sensor has on board
linearization and temperature compensation over the range of -20 to +50 C.
The sensor can be calibrated via two push buttons, one for zero and one for span.

2 INSTALLATION
IMPORTANT
It is important that the instrument has been installed and powered for a minimum of 10
minutes before it is used to monitor the gases concentration in the environment.
2.1 Siting the ‘FGD14’
Mounting positions for detector heads need to be considered individually, some points
for consideration are:
•Sensors for detecting gases that are lighter than air should be positioned at a
high level.
•Sensors for detection of gases heavier than air should be located as low as
practically possible.
•Ensure all sensors are mounted to allow calibration and maintenance to be
carried out as required.
•Ensure the proposed site will not interfere with movement of existing
equipment, e.g. cranes, doors etc
•Install all cables neatly and securely.
•Avoid siting the sensors adjacent to potential sources of radio frequency
interference, e.g. radio transmitters, control switchgear, motors etc.
•Avoid mounting the instrument where it may be subjected to sudden
transients in ambient temperature (e.g. above a heater/radiator).
2.2 Power Supply Options
The FGD14 is available with one of two power supply options.
2.2.1 Mains Powered
A universal power supply is fitted that operates in the range of 85-265Vac, 47-400 Hz.
This allows worldwide use without the need to configure for location specific mains
voltage requirements.
2.2.2 DC Powered
Alternatively a DC power supply can be installed capable of accepting voltages in the
range of 8-30V DC.

2.3 Wire Termination
All connections should be made according to the diagram below. It is advised that
‘Bootlace Ferrules’ or ‘flat blade crimps’ be used for tidy and reliable connections of
wires into the Detector Head connectors.
Note: The yellow mains cover must be removed to gain access to the mains input
connector.
Isolate the mains supply before removing cover.
Ensure that the protective cover is securely replaced after terminating the mains input

3 MENU SYSTEM
Important
Whenever the menu system is entered the instrument will cease to measure
current gas levels. However normal operation is always returned following a
period of keypad inactivity (or when the menu system is exited).
3.1 Display Unit
In order to gain access to the calibration switches and test points, release the screw
situated between the letters A and T of the chrome STATUS label on the Detector
Head front panel. The screw does not need to be completely removed, only release it
far enough so that the STATUS label can rotate revealing the calibration switches.
The buttons are designated as follows:
UP DOWN ENTER MENU

3.2 Menu Mode Selection
Several calibration modes exist in the detector head and these are accessible via the
instruments simple menu system. To select a calibration mode follow this procedure:
•Press the MENU button and C: 1 appears on the display.
•Press UP or DOWN until the required calibration mode is displayed on the
screen.
•Press ENTER to select the calibration mode.
•To exit the calibration mode press MENU.
While the instrument is in a calibration mode –any data displayed on the screen will
alternate between the cal number and the reading.

3.3 Alarm Test
The FGD14 is equipped with an alarm test function. During alarm the relays, Leds and
sounder will operate, see section 3.5
In order to gain access to the alarm test switch see section 3.1.
When the FGD14 is operating normally press the UP button to activate the alarm
system. The alarm will continue to operate whilst the UP button is pressed and for a
further 5 seconds when it is released.
3.4 Calibration
The infrared sensors used within the Status Scientific Controls ‘FGD14’ Detector
Heads do not respond linearly with respect to gas levels to which they are exposed.
The FGD firmware contains complex mathematical formulae to allow a linear
response to be calculated and indicated on the instrument display.
Care should be taken to ensure that calibration procedures are followed and any
notes included are read and understood. Failure to adhere with the recommendations
within this manual may seriously impair the instruments ability to accurately indicate
the gas levels to which it is being exposed.
3.4.1 Calibration Gas Flow Rates
Most gas sensors including the infrared sensors are sensitive to pressure transients
and therefore it is important that the flow rate of gas into the sensor housing is not
excessive during calibrations. Care must also be taken to ensure the exhaust from the
sensor housing is not restricted. The recommended flow rate of calibration gases is
500 - 750cc/min.

3.4.2 Zero
There are two zero functions within the FGD14, the instrument zero and the sensor
zero. The sensor Zero can only be achieved internally.
3.4.2.1 Zero Instrument
This is a calibration feature. It allows the instrument to determine the sensor output
under zero gas conditions.
•Apply target free gas to the sensor inlet and allow enough time for the sensor
to respond and all gas to be purged (typically 2 minutes dependent upon flow
rate).
•Select calibration mode C: 1 (refer to section 3.2) and press ENTER.
•Press ENTER to perform the ZERO calibration. Pressing MENU instead of
ENTER aborts the calibration (the ZERO factor will still be displayed on exit).
•Press MENU –the display will show the ZERO factor for the instrument
before returning to its standard mode of operation.
The ZERO factor should be recorded on any calibration certificates.

3.4.2.2 Zero Sensor
Remove the 4 screws located at each corner of the instrument to gain access to the
sensor calibration buttons within the unit.
Zero calibration of the sensor can be carried out by using the button on the circuit
board as seen in Fig 1 below.
The Zero button only works when the FGD10B Infrared has been powered for a
minimum of 10 minutes.
Fig 1
Ensure the sensor is in a zero-gas environment.
Carbon Dioxide sensors cannot be zeroed in air due to the background levels of
CO2present. These sensors are best zeroed whilst being exposed to 100%
nitrogen.
Where a purging gas has to be applied, use a flow rate of between 300 and
500cc/min. Allow sufficient time for the sensor to respond.
Press the Zero button and hold for a minimum of 5 seconds to zero the sensor.
Note: the Instrument zero must be carried out after a sensor zero.

3.4.3 Span
There are two span functions within the FGD14, the instrument span and the sensor
span. The sensor Span can only be achieved internally.
3.4.3.1 Span Instrument
This is a calibration feature. It allows the instrument to determine the sensor output
when it is exposed to a know concentration of gas.
•Apply a known concentration of Hydrocarbon gas (typically 2.50% CO2) to the
sensor inlet and allow enough time for the sensor to respond. i.e. until the
reading remains constant.
•Select calibration mode C: 2 (refer to section 3.2) and press ENTER.
•Using the UP and DOWN buttons, adjust the displayed reading so that it
matches the calibration gas concentration.
•Press ENTER to perform the SPAN calibration. Pressing MENU instead of
ENTER aborts the calibration (the SPAN factor will still be displayed on exit).
•Press MENU –the display will show the SPAN factor for the instrument
before returning to its standard mode of operation.
The SPAN factor should be recorded on any calibration certificates.

Always zero the sensor prior to performing a span operation.
Fig 2
Apply a known concentration of gas (applicable to sensor type) at a flow
rate of between 200 and 500cc/min. Allow time for the sensor to respond.
Press the Span button and hold for a minimum of 5 seconds to span the
sensor.
Turn off and disconnect the calibration gas.
Note: The calibration gas level must match with the level stored in the sensor. If
the gas level is does not match then the sensor must be updated with
specialized equipment.
Note: the Instrument span must be carried out after a sensor span.
