Electrical Voltage; Explosion Hazard - Bühler technologies P2.2 Atex Notice De Montage

P2.x ATEX
DANGER

Electrical voltage

Electrocution hazard.
a) Disconnect the device from power supply.
b) Make sure that the equipment cannot be reconnected to
mains unintentionally.
c) The device must be opened by trained staff only.
d) Regard correct mains voltage.
DANGER
Danger of explosions, danger of poisoning from poison-
ous corrosive gases
During maintenance work, depending on the medium used,
explosive and/or poisonous corrosive gases could escape, and
this could lead to a danger of explosion or could be hazardous
to health.
a) Inspect the leak tightness of your sampling system before
putting the device into operation.
b) Ensure that gases that are hazardous to health are dis-
charged safely.
c) Turn off the gas supply before beginning any mainten-
ance or repair work and flush the gas lines with inert gas
or air. Secure the gas supply so that it cannot be turned
on unintentionally.
d) Protect yourself during maintenance from poisonous /
corrosive gases. Wear appropriate protective equipment.
DANGER

Explosion hazard

Life and explosion risk may result from gas leakage due to im-
proper use.
a) Use the devices only as described in this manual.
b) Regard the process conditions.
c) Check tubes and hoses for leakage.
DANGER
Adiabatic compression (explosion hazard)!
In case of adiabatic compression, high gas temperatures may
occur. The operator is responsible to consider this situation.
Make sure to obey the allowed technical specifications and
ambient conditions (see data sheet), take special attention to
the media temperature with respect to temperature class T3
or T4. These vary in addition to gas composition and ambient
conditions. Where necessary, the operator must install tem-
perature sensors for monitoring and must automatically shut
down the sample gas pump should the temperature exceed
the limits.

DANGER
DANGER - Explosion danger in case of high temperat-
ures
Temperature of the device depends on the medium temper-
ature. Correlation between medium temperature and tem-
perature classes is given in the data sheets.
Observe maximum temperature classes T3 or T4 for the
pumps and the allowed ambient temperatures and medium
temperatures.
CAUTION
Tilting risk
Damage of the device
Secure the device against any sudden translocation during
maintenance.
CAUTION
Hot surface
Burning hazard
According to the product type and operation conditions, the
temperature of the housing may exceed 50 °C during opera-
tion.
Depending on the conditions at the installation site it may be
necessary to provide these areas with appropriate warning
signs.
3 Transport and storage
Only transport the product inside the original packaging or a
suitable alternative.
The equipment must be protected from moisture and heat
when not in use. They must be stored in a covered, dry and
dust-free room at a temperature between -20 °C to +40 °C
(-4 °F to 104 °F). To avoid bearing damage, ensure a vibration-
free environment (v eff<0.2 mm/s).
Outdoor storage is prohibited. On principle the operator must
meet all applicable standards with respect to preventing dam-
age due to lightning, which could result in sample gas pump
damage.
Storage areas must not contain any equipment generating
ozone, e.g. fluorescent lighting, mercury vapour lamps, high
voltage electrical equipment.
After prolonged storage or downtimes test the insulation res-
istance of the winding, phase against phase and phase
against mass, prior to initial operation. Moist windings can
cause current leaks, flashovers and breakdown. The insulation
resistance of the stator winding must be at least 1.5 MΩ meas-
ured at a winding temperature of 20 °C (68 °F). Values below
this require drying the winding.
The motor shaft should be turned occasionally to ensure the
entire bearing remains lubricated. To do so, remove the three
cross-tip screws (9) of the console cover (8) and remove. This
exposes the crank gear (10). You can now turn the motor shaft
on it.
