Instructions for use
|
Dräger PointGard 2000 Series
1.2.1 PointGard 2200 CAT remote
The sensing heads can be operated in hazardous areas with
potentially explosive atmospheres of zones 1 and 2, zones 21
and 22 and Class I and II, Div 1 and 2.
Depending on the type of protection of the actually selected
sensing head.
CAUTION
Explosion hazard
The instrument itself is not suited for operation in hazardous
areas with potentially explosive atmospheres.
► Not to be used in potentially explosive atmospheres.
1.3
Mechanical installation
– Responsibility for correct placement of the instrument
rests with the end user. If in doubt about placement,
consult with application engineers.
– Strict compliance must be given to the local, state, national
codes and regulations that govern the installation of gas
monitoring equipment.
For correct placement the following should be considered:
– Physical properties of the gas or vapor to be detected (e.
g. density)
– Air flow patterns in the area
– Personnel considerations (e. g. breathing/working height)
– Degree of accessibility required for maintenance purposes
1.4
Electrical installation
– Strict compliance must be given to the electrical codes
that govern the routing and connection of electrical power
and signal cables to gas monitoring equipment.
– The electrical network in which the instrument is installed
must have a circuit breaker or fuse.
– The circuit breaker or fuse must be easily accessible, and
marked as corresponding to the instrument.
– Ferrules must be used.
– Wire insulation must be stripped by 5 to 7mm.
CAUTION
Explosion hazard
Not tested in oxygen enriched atmospheres (>21% O
off-scale readings may indicate a combustible concentration.
► Not to be used in oxygen enriched atmospheres.
Analog interface
– To ensure proper operation of the instrument, the
impedance of the 4 to 20 mA signal loop must not exceed
500 Ohms. Depending on the operating voltage and
according to the application , certain minimum
impedances must be observed .
