The nature of the laser beam path and beam width further ensures that it should be
impossible to cause any eye damage. The analyzer has warning labels at appropriate
positions in accordance with USA 21 CFR 1040.10.
Conditions for safe use (Europe)
• The maximum sample gas temperature that the analyzer can operate with is 320 °F
(160 °C).
• The purge controller keypad mounted on the front of the equipment shall not be
exposed to direct UV light sources or direct sunlight. Example methods of protection
include, but are not limited to, indoor applications away from UV sources and outdoor
locations under shading. As part of regular inspections, if damage to or deterioration of
the membrane keypad is detected, take the unit out of service for repair or
replacement.
• The purge controller bypass function shall only be enabled during setup or
maintenance and only when the area is known to be non-hazardous.
• The equipment shall be installed in an area of not more than pollution degree 2 as
defined in IEC 60664-1.
• The cable glands used in the equipment are only suitable for use in areas with a low risk
of mechanical damage and must be suitably protected.
• The purge controller automatically monitors the internal pressure of the enclosure and
will output any fault conditions onto contact K2. It is the end user's responsibility to
connect this contact to a suitable facility such as an alarm or an automatic shutdown
system.
• For correct operation, the on-site pressurizing air supply must be capable of providing
at least 25 L/min for leakage compensation.
• When using the analyzer variant fitted with the Elmess gas cell heater certified as BVS
14ATEXE155U and IECEx BVS 14.0106U, the equipment top compartment should be
cooled with a source of compressed air at a minimum flow rate of 280 L/min.
• The Elmess gas cell heater, certified as BVS 14ATEXE155U and IECEx BVS 14.0106U,
may only be used in combination with the ESI Technology gas cell pressure transducer,
certified as TRAC12ATEX0060X and IECEx TRC 12.0025X.
Conditions for safe use (North America)
• The maximum sample gas temperature that the analyzer can operate with is 176 °F (80
°C).
• The purge controller keypad mounted on the front of the equipment shall not be
exposed to direct UV light sources or direct sunlight. Example methods of protection
include, but are not limited to, indoor applications away from UV sources and outdoor
locations under shading. As part of regular inspections, if damage to or deterioration of
the membrane keypad is detected, take the unit out of service for repair or
replacement.
• The purge controller bypass function shall only be enabled during setup or
