1.3 About the Analyzer
The G36p Oxygen Analyzer continuously measures the content of oxygen with concen-
trations up to 21.0 %. The analyzer can be used to measure the content of oxygen in N2
or CO2 based inert gas, or in stack gas, or in connection with exhaust gas recirculation
(EGR). The G36p Oxygen Analyzer is designed for front panel mounting.
The G36p Oxygen Analyzer uses a zirconia sensor. The zirconium dioxide sensors have
long been established as industry standards. The G36p uses a new type of zirconia sensor,
which can be used in a wide range of applications.
The most important element of
the sensor is the zirco
nia cell.
At high temperatures, the oxy-
gen ions can diffuse through
the zirconium dioxide mem-
brane. When the membrane is
exposed to environment that
contains different amounts of
oxygen (e.g. the sensor inter-
nal reference gas on one side
and sample gas on
the other),
nature seeks to balance itself,
and the transportation of ions
through the mem
brane will
generate an electrical charge.

This charge depends on the amount of the passing oxygen ions i.e. the difference between
the oxygen levels in the sample gas and the reference gas. This voltage will be detected
and converted into a signal that is proportional to the oxygen concentration in the sample

sample gas will be shown in the display.
The G36p Oxygen Analyzer has CE and MED markings as well as DNV, Bureau Veritas
and Lloyd's Register Type Approvals.

3Analyzer Installation & Connections
Read this chapter in its entirety before installing the analyzer.
3.1 Control at Delivery
When you receive the G36p Oxygen Analyzer, please inspect, and confirm that the re-
ceived scope of supply is in accordance with the packing list and that nothing is dam-
aged. Any discrepancy should be reported to the supplier immediately. If any of the re-
ceived parts are damaged, the shipping company should be informed, and new parts
should be made available before completing the installation
3.2 Where to Install the Analyzer
The G36p is designed for front mounting in control panels. To obtain IP55 tightness, the
included gasket must be mounted between the hole that is cut in the panel and the display
front.
Satisfactory operation, faultless functions, and minimal maintenance of the G36p are
achieved by paying attention to the following notes:
The equipment should be installed in a clean area away from dust, oil mist, and
moisture. The analyzer should be installed at viewing level in an area with good ac-
cess for operating and servicing. The location and installation of the analyzer must
be chosen, so that the ambient temperature is below 70°C at any time.
The gasses supplied to the sensor must have a constant flow and pressure. This flow
and pressure control is achieved with the sampling system that is typically delivered
with the analyzer. Please consult the respective manual or contact Green Instruments
A/S.
The sensor houses for both SEN1 and SEN9 have 1/8” BSP connection. Sampling
tube and vent line should be arranged in the way which ensures the flow and pres-
sure at sensor house constant and within the required range.
The sensor can be installed up to 6 m from the analyzer. The sensor and the sensor
house shall be mounted horizontally (sensor pointing sideways) or downwards (sen-
sor pointing down) to prevent the water condensation collecting at the sensor house.

3.3 Safety Aspects
Warning
Follow the operating instructions!
Make sure that all power and signal cables are connected correctly before operating
the analyzer.
The sensor must not be exposed to strong mechanical shocks. Otherwise the sensor
element may crack without visible damage.
The sensor and sensor housing are hot and can cause severe burning of personnel if
not handled with care.
The G36p Oxygen Analyzer is only suitable for installation in a safe, non-hazardous
area and not suitable for use with flammable sample gases.
The installation and operation of the G36p
Oxygen Analyzer and associated equip-
ment must be carried out by skilled, trained, and certified personnel. Green Instru-
ments A/S does not take any responsibility for the operation of the analyzer and as-
sociated equipment whatsoever.
The analyzer must only be applied as described in this instruction manual. If the ana-
lyzer is used in a manner not specified by Green Instruments, the protection provid-
ed by the analyzer may be impaired.
Successful and safe operation of this equipment is dependent upon proper handling,
installation, operation, and maintenance.
Hazardous voltage!
Always disconnect the power before installing or servicing the analyzer. Ignoring this
warning can result in severe personal injury or material damage. Read the manual care-
fully to ensure that all power and signal leads are connected correctly.
Make sure that the analyzer is connected to the correct voltage (see rating marked on the
analyzer name plate).
Circuit breaker!
The installation must include a way to switch off the electrical power by a clearly marked
switch or circuit breaker external to the analyzer. The external switch or circuit breaker
shall be placed in close proximity to the analyzer and within easy reach of the operator.
Overload protection!
For compliance with the IEC 61010-1 (2003) safety requirements, the installation must
include a means of overcurrent protection to provide protection against excessive energy
being drawn from the power supply system in case of a fault in the analyzer.
