GA5000 gas analyser OMGA5KN4.4
Copyright Geotech Page 7 of 113
The equipment is only certified for use in ambient temperatures in the range -10ºC
to +50ºC and should not be used outside this range.
The equipment must not be used in an atmosphere of greater than 21% oxygen.
5) Repair of this equipment shall be carried out in accordance with the applicable
code of practice.
When used in a hazardous area only use GF5.2 temperature probe (SIRA
11ATEX2197X and IECEx SIR11.0089X). For connector C, the GF5.4 anemometer
(BVS 04ATEXE194) for use with ATEX only. The analyser should not be connected
to any other devices in the hazardous area including the GF-USB lead (connector A)
or GF3.9 battery charger (connector B) supplied with the analyser.
Do not charge, recharge or open in a potentially explosive atmosphere.
In hazardous area only use “Temperature Probe GF5.2” in Connector B.
Connector C (Uo=10V,lo=5mA,Po=50mW,Ci=0,Li=0,Co=100uF,Lo=1000mH),
Connector B (Uo=5V,lo=6mA,Po=7mW,Ci=0,Li=0,Co=100uF,Lo=1000mH)
MAXIMUM NON-HAZARDOUS SUPPLIES:
Connector A - Um=6V Connector B - Um=10.1V
The safe area apparatus that is to be connected to the USB Port shall be a Safety
Extra Low Voltage (SELV) or Protective Extra Low Voltage (PELV) circuit.
Only a Geotechnical Instrument battery pack part number 20087 or 2011113 is
permitted as a replacement. This battery pack shall only be changed in a safe area
by Geotech personnel or authorised distributors.
Only Battery Charger type GF3.9 shall be used to recharge the batteries via
Connector ‘B’.
If the equipment is likely to come into contact with aggressive substances, e.g.
acidic liquids or gases that may attack metals, or solvents that may affect
polymeric materials, then it is the responsibility of the user to take suitable
precautions, e.g. regular checks as part of routine inspections or establishing from
the material’s data sheet that it is resistant to specific chemicals that prevent it
from being adversely affected, thus ensuring that the type of protection is not
compromised.
The relative pressure range is +/-500 mbar. Note, however, that the input pressure
should not exceed +/- 500 mbar relative to atmospheric pressure and the output
pressure should not exceed +/- 100 mbar relative to atmospheric pressure.
