Esmach NSE 30 Notice D'utilisation Et De Maintenance page 13

To prevent the danger of faulty operation of the control circuit, one end of the transformer
secondary circuit is connected to earth; in addition, fuses are fitted both on the primary and
secondary circuits.
The controls and signalling devices together with the symbols indicating their functions are fit-
ted on a panel; IP 54 protection rating is guaranteed overall by the characteristics of the indi-
vidual electrical components and by the seal fitted between the housing and the cover.
The machine as a whole is protected to IP 44.
PREVENTIVE MEASURES TO GUARANTEE HYGIENE
The following should be noted in particular:
A. The elements or parts of the machine (bowl, tool, column and bowl protection) that come
into contact with the mixture ingredients or are in the FOOD AREA are made of
STAINLESS STEEL (the bowl protection can be made of thermoformed ABS suitable for
contact with food).
B. The elements or parts of the machine that may come into contact with the above food
products or are in the so-called DIRTYING OR SPLASH AREA are made of STAINLESS
STEEL or OVEN PAINTED STEEL.
Measures to protect against flour dust
If the machine is provided with bowl protection with stainless steel grille, in order to limit the
production of flour dust, the operating time at first speed cannot be set at a value below 120
seconds.
PREVENTIVE MEASURES AGAINST NOISE HAZARDS
When the machine is operating empty, which is considered the most unfavourable condition, it
emits a weighted equivalent continuous acoustic pressure level of 70 dB (A).
As it is not possible to establish a set work place for this machine, the measurement was taken
at the point shown in figure n° 8 at a height of 1.6 m from the ground and 1.00 m from the
surface of the machine, in the direction of maximum sound emission.
The measurements were taken with a QUEST MOD. 1800 class I instrument.
From these findings it can be affirmed that the machine does not produce irritating or harmful
noise or noise requiring the use of headsets or earplugs.
