NOTE
The Rotomec couplings with conical bush are provided with keyholes
(optionals) for locking the shaft during keying.
4.2.6
Remove the sling and the hoisting device, then reinsert the screw and the nut
previously removed and screw it in tightly.
4.2.7
The transmission oil carries out an important lubrication function inside the
hydromechanics coupling; therefore the motor or the drive parts should
not be activated, if it is missing. Before starting the motor, complete the
operation described in section 4.6 STANDARD AND ATEX FLUID COUPLING
COMMISSIONING.
CAUTION
Do not start up the motor or the drive part without or with insufficient
oil filling. DANGER OF BEARING SEIZURE, OVERHEATING AND/OR FIRE
IGNITION.

4.6 ROTOMEC COUPLING COMMISSIONING STANDARD AND ATEX
MANUFACTURE
Upon completion of the mechanical assembly of the hydromechanic coupling on
the driven and drive end according to the instructions set out in the previous
sections, it is possible to complete the commissioning as follows:
CAUTION
Do not commission the ROTOMEC hydromechanic coupling before
the machine incorporating it has obtained the certificate of compliance
with the Machine Directive 2006/42/CE, the ATEX 94/9/CE Directive and
other specific applicable directives.
4.6.1 HYDROMECHANIC COUPLING WITH TF (Fusibile Plug)
To complete the installation of the hydromechanic coupling equipped with the
overheating control device TF, it is necessary to observe what follows:
- Set an automatic motor shutdown signal in case of device triggering, which
signals transmission/lubrication oil leakage.
DANGER OF OVERHEATING, SEIZURE AND FIRE.
- Set up suitable containment and containers to collect hot transmission oil.
DANGER OF HOT OIL SPLASHES, SCALDING AND SLIPPERY FLOOR.
- Isolate the hydromechanic coupling with suitable interlocked protections, which
prevent the personnel from interfering with the coupling moving components
and/or the live components of the drive end.
- When couplings are installed in an environment with explosive atmosphere ATEX,
some accident- prevention guards prevent any contact with the rotating components
and/or protect them from any metal object fall or ejection even from outside.
DANGER OF SPARKS AND FIRE IGNITION.
4.6.2 HYDROMECHANIC COUPLING WITH TE (Expandable Trip Plug)
To complete the installation of the hydromechanic couplings equipped with the
overheating control device TE with ET-A, observe what follows:
- Set an automatic motor shutdown in case of device triggering.
DANGER OF OVERHEATING.
- Isolate the hydromechanic coupling with suitable interlocked guards, which
prevent the personnel from interfering with the coupling moving components
and/or the live components of the drive end.
- When hydromechanic couplings are installed in a hazardous zone ATEX, the
guards must be designed so to prevent any contact with the rotating compo-
nents and/or to protect them against any fall or ejection of metal objects.
DANGER OF SPARKS AND FIRE IGNITION.
4.6.3 HYDROMECHANIC COUPLING WITH PM/T09 (Plug with Thermostat and rpm Controller)
To complete the installation of the hydromechanic couplings equipped with the
PM-T09 overheating control unit, observe what follows:
- Set an automatic motor shutdown in case of device triggering.
DANGER OF
OVERHEATING.
- Isolate the hydromechanic coupling with suitable interlocked protections, which
prevent the personnel from interfering with the coupling moving components
and/or the live components of the drive end.
- The installation of the coupling in the ATEX environment requires some guards
to prevent interference with rotating interferences are installed in a hazardous
zone, the guards must be designed so to prevent any contact with the rotating
components and/or the metal objects from interfering with operation, as a result
of fall or sudden ejection.
DANGER OF SPARKS AND FIRE IGNITION.
