3BFP 000 050 R0101 REV E
The machine parameter values for relay settings are informed in the document “Performance
data of machine” which is included in the documentation provided with the machine.
NOTE: The machine manufacturer is not responsible for the adjusting the protection
equipment at the site.
5.6 First test start
5.6.1 General
The first test start is a standard procedure after the installation and alignment procedure is
finished, the mechanical and electrical connections are made, the commissioning procedure is
gone through and the protective devices are active.
NOTE: If possible, the first start is made with uncoupled coupling between the driving and
driven machine. The load on the machine must in any case be as small as possible.
5.6.2 Precautions before first test start
A visual inspection of the machine and its equipment is made before the first test start. It is
verified that all necessary tasks, checking and adjustments have been performed.
Before the test start, the following checks and measures must be made:
• If the coupling half is not assembled, the shaft extension key is either locked or removed
***Following bullet for bearing type: Sleeve bearing
• The sleeve bearing oil reservoirs and possible oil supply systems are filled with
recommended oil to the correct level. The oil supply system is turned on
***Following bullet for bearing type: Rolling bearing
• The rotor is turned by hand, and it is verified that no abnormal noises are heard from the
bearings. To turn a rotor with sleeve bearings, a simple lever arm is needed
***Following bullet for cooling method: Air-to-water
• In case of water-cooled machines, the cooling water is turned on. The tightness of the
flanges and the cooling unit is checked
• The cabling, cables and bus bar connections are verified to be according to the connection
diagram
• The earth connections and earthing devices are verified
• The starting, control, protection, and alarm relays of each device are inspected
• The insulation resistance of the windings and other equipment verified
• The machine covers are assembled, and the shaft seals are tightly fitted in
• The machine and the environment are cleaned
***Following bullet for protection type: Ex p
• Ex machine enclosure has been purged and it is pressurized. Refer to the purging and
pressurizing system instructions.
