Instruction Manual
This manual contains important Health & Safety information
SAFETY and EMC INFORMATION
Please read this section carefully before installing the instrument.
This instrument meets the requirements of the European directives specified below. However it is the responsibility of
the installer to ensure the safety and EMC compliance of any particular installation
Equipment:
The G1010 range of gas analysers.
Safety:
These instruments comply with the European Low Voltage Directive 73/23/EEC, amended by 93/68/EEC by
the application of the safety standard EN61010(93)
Installation and servicing should only be carried out by suitably qualified personnel.
Electromagnetic Compatibility:
These instruments comply with the EMC directive 89/336/EMC amended by
93/68/EEC, by the application of the following standards:
EN50081 Part1: 1993 (Generic Emission Standard)
EN50082 Part1: 1995 (Generic Immunity Standard)
Installation Requirements for EMC:
To ensure compliance with the European EMC directive certain installation
precautions are necessary as follows:
Instrument Rear Panel Rating
The G1010 instrument is designed as a panel mounted instrument and for this reason the back panel is rated as service
only. All service personnel should take electrostatic precautions before work is carried out at the rear of the instrument.
Radiated Emissions
In light industrial/domestic applications it may be necessary to suppress emissions from the power cable by fitting a
ferrite choke to the mains supply lead. The mains cable should be wound twice through the choke. (This choke is
available on request by quoting: Part No: 418-0045).
Routing of wires
To minimise the pick-up of electrical noise all signal wiring should be shielded and routed away from power cables.

Speed of response 3.0 INSTALLATION T90 - variable depending on sensor and concentration. Approximately 3s at % levels and 20s at ppm levels. The ppm 3.1 Unpacking and visual checking figure assumes that the sensor is purged down. Take all standard precautions when opening packages. In Analogue outputs particular avoid the use of long bladed cutters. - Page 4 Page 4 of 18 3.4 Connections Page 5 of 18 The sensor, output signals and the supply should be connected as Sample outlet shown below. See section 3.8 for details of optional remote sensor version. Sample Flow ML/MIN The flow meter and pump can be placed on the inlet if it is more Terminal Sensor +ve (red wire) convenient and both are adequately leak tight etc.
- Page 5 This is particularly important for instruments fitted with L sensors, irrespective of the positioning of flow meters etc. Page 7 of 18 Page 6 of 18 It is important to fit a pipe of at least 300mm length to the WARNING - Do not leave an L sensor exposed to oxygen sample vent/outlet connection to prevent back diffusion of air.

Once the required value is displayed, press the 4.1 Switching on Edit button once to store the value in the analyser’s memory. When the analyser is fully connected, it may be switched on.
- Page 8 varies according to how far the oxygen concentration in the sample 5.0 MAINTENANCE AND CALIBRATION is from the gas in contact with the sensor at start up (usually air). CHECKS Figs 4 & 5 show the typical response time from an air condition for N and L type sensors.
- Page 9 5.1.1 Sensor failure modes All known sensor failure modes result in a loss or lowering of output. Thus applications that look for oxygen depletion are automatically fail safe and vice-versa. 5.2 Calibration interval It is recommended that the calibration is verified every month. This Response of an N type sensor from an air saturated condition when zero grade nitrogen is applied.
- Page 10 Isolate the analyser from the process gas and pass the calibration concentrations up to 5% oxygen in nitrogen. Beyond 5% the sensor gas through it. A full calibration requires two calibration points begins to deviate from its standard output equation. N.B. Air may referred to as upper and lower, although the lower point can be be used for convenience if nothing else is available.
