14.2. Additional recommendations for the - ATEX Version
valid for Ecocut 2406 - 2-stage and Ecocut 2406 - 2-stage in series
14.2.1.
Before the machine is installed, check that the flameproofing characteristics coded on the electric pump data
plate conform to the classification requirements of the installation area.
14.2.2.
Do not work on cable glands, connectors, or open the motor casing; these works are reserved to Häny au-
thorised workshops. The flameproof joints cannot be repaired. It is possible to shorten the electrical cables
while respecting a minimum length of 3000 mm (EN60079-14).
14.2.3.
The operating characteristics of these machines must comply with the characteristics specified in the name -
plate and in the attached EX certificate.
14.2.4.
The minimum head is at the top of the electric motor for machines operating in S1 service mode; instead, a
head over the motor in case of cooling system activation is not required (always check NPSH). It is located
over the pump casing for electric pumps operating with cooling system activated.
14.2.5.
It is obligatory to connect the thermal probes to the control equipment of the electric pump. The temperature
sensor tripping must cut the electric pump power supply. Reset must not be automatic, but should be pos-
sible only after inspection by qualified staff.
If the motor is equipped with PTC probes, read the manual for information on installation.
14.2.6.
No change to the machines or replacement of parts of the electric motors is allowed. It is allowed to only
replace wet end parts (numbered L1 to L19 of the Section in question) with identical genuine parts (same
part number or same code on the part) in case of normal wear and tear. Any service other than ordinary
maintenance can only be carried out by Häny AG. The class of screws used to assemble the flameproof
casing must be A2-70 ISO 3506-1.
14.2.7.
The optional use of the conductivity sensor is conditioned on the use of a control device installed in the con-
trol panel and compliant with potentially explosive environment requirements.
14.2.8.
The electric pump is supplied with the power cable permanently connected and without switch. The electric
cable must therefore be connected to the power supply in a safe area or using one of the protection methods
provided for in the EN 60079-0 standard with a switch off button. The cable cannot be reduced in length.
14.2.9.
Activate all possible measures to prevent the following malfunctions as they could cause and trigger an ex-
plosion:
- dry running of the pump or 0/Q capacity: foresee a pressure and/or capacity probe directly connected to
the control panel with manual restarting, as to avoid the electric pump operating in such conditions;
- pump shaft bearings damage: in case of increased vibrations and/or noise during operation, stop the pump
and send it to authorized Häny workshop.
