Startup
After the first startup of the external oilsupply system check the oil level.
•
Check the oil level in the gear unit.
When the oil has cooled down, the oil level should be in the middle of the oilsight glass or of
the angular oillevel indicator.
When the oil is warm it may slightly exceed the upper mark. It must in no case be allowed to fall
below the lower mark; if necessary, top up to the correct level.
7.2.1
Oil level
•
Check the oil level in the gearunit housing. To do so, the gear unit must be shut down.
Depending on the type the following oil levels apply:
─ Middle of the oilsight glass.
─ Middle markings on the angular oillevel indicator.
When the oil has cooled down, the oil level must be in the middle of the oilsight glass or of the angular
oillevel indicator. When the oil is warm it may slightly exceed the upper mark.
It must in no case be allowed to fall below the lower mark; if necessary, top up to the
correct level.
7.2.2
Gear unit with auxiliary drive unit
Before startup, check whether the overrunning clutch can be turned manually in the
freewheeling direction without exerting undue force.
Observe the directionofrotation arrows on the housing.
The
overrunning clutch
is in freewheeling operation if the motor shaft of the auxiliary drive
is rotated in opposed operating direction of rotation.
When rotating in the operating direction of rotation, the blocking action of the overrunning
clutch (carrier operation) becomes effective. Coupling and, thus, rotation of the output shaft of
the main gear unit in operating direction of rotation takes place.
To avoid damaging the backstop or the gear unit, the motor must not be run adversely
to the stop direction of the gear unit.
Observe the notice fixed to the gear unit.
Before connecting the main and auxiliary gear motor, the respective rotating field of
the threephase supply network should be determined by means of a phasesequence
indicator and both motors should be connected according to the predetermined
direction of rotation.
The main motor and the motor of the auxiliary drive should be interlocked electrically in such
a manner that always only one of the two motors can be switched on at the same time.
Prior to startup, the disabling function of the speedmonitoring device of the auxiliary drive,
designed for maintenance drive, should be checked according to item 5.11.
Startup may take place, after the oil quantity specified on the instruction plate has
been filled in by the oilfiller screw at the lubricating point on the intermediate flange
(see the orderrelated specification on the dimensioned drawing).
Always use oil of the same type as that for the gear unit.
For details regarding the auxiliary gear unit please see the Special operating instructions.
((The auxiliary gear unit is delivered ex works with oil filling.)
