9. STARTUP
Before starting up the machine incorporating the gear reducers make sure that:
The machine is compliant with Machinery Directive 2006/42/EC, in addition to other safety regulations in force;
It is compliant with regulations EN60204-1 and EN 60079-0;
That all the supply voltages, motor and auxiliary services match the required ones for that component;
The facility complies with all applicable standards on safety and health of people at the workplace;
Moreover:
Remove all safety devices installed for the handling phase;
Go ahead with the filling stage according to the amount and type of oil reported on the relevant label on the gear
reducer. If lubricant top-ups are required, use the same brand and type of oil already in place. Use lubricants type-
approved by Motovario (see table). Check the correct amount of oil by using the relevant indicator or dipstick.
Make sure the breather plug is mounted and free from obstructions;
Check that all the devices and accessories installed parts operate efficiently;
Make sure the gear reducer is clean on the outside, especially the areas most involved in cooling;
For cleaning purposes, use materials that do not generate electrostatic charges;
Check for any lubricant leaks, especially in the sealing ring areas;
During start-up we recommend running the equipment with ‘no load’ for a few minutes to ensure the oil is distributed
and reaches an optimal temperature and viscosity. Some air pockets trapped between the gears and the case may be
released downstream of this operation, so check the lubricant level again and top up if necessary;
During the first hour of operation, check for any abnormal vibrations and noise or overheating. If necessary, stop the
motor immediately and contact MOTOVARIO’s TECHNICAL SERVICE.
After stopping the motor drive
, before proceeding with disassembly, wait until the temperature of the gear reducer
has dropped below 40 °C;
The equipment must be started gradually, without immediately applying the maximum load required by the machine,
in order to make sure there are no operating anomalies or residual application issues;
Carry out a run-in (at about 40% of the nominal limit of the gear reducer) for about 300 hours to reach the maximum
level of reliability of the gear reducer. During this period, monitor the gear reducer to promptly detect potential
problems as reported in the table in Paragraph 11. For category II equipment, perform this check every day for the first
week of service and then every week during the following month. Check all the tightening points after the first week
of operation.
During start-up at full machine load, monitor the gear reducer’s surface temperature according to the procedures
reported in the SURFACE TEMPERATURE paragraph. If the condition indicated in the paragraph is not observed, stop
the gear reducer immediately and contact Motovario’s Technical Service.
Do not use the unit:
In an environment with fumes or abrasive and/or corrosive dust;
In direct contact with food products in bulk.
Dangerous area
The dangerous area of the unit is the rotating shaft extension where any person could be subject to
mechanical risks from direct contact (cutting, dragging, crushing).
Make the machine compliant with DIRECTIVE 2006/42/EC providing a safety guard when the unit works in
accessible zones.
