Gear unit with backstop

Observe details at item 5.9, "Backstop"!
Before start­up, check whether the backstop can be turned manually in the free­wheeling direction without
exerting undue force. Observe the direction­of­rotation arrows on the housing.
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.
If a backstop with release mechanism is used, the operating instructions for this
backstop must be followed.
Moreover, the dimension "x
that stated on the backstop rating plate.
Before connecting the motor, determine the direction of rotation of the three­phase current supply using
a phase­sequence indicator, and connect the motor in accordance with the pre­determined direction of
rotation.
The unit can be started up once the amount of oil indicated on the notice has been
poured in through the oil filler plug screw of the backstop. Always use oil of the same
type and viscosity as for the gear unit.
7.2.5

Gear unit with temperature measurement

During first start­up and after maintenance work, the oil sump temperature must be
measured during correct use (maximum machine performance) after appropriate
running in.
The difference in temperature from the maximum ambient temperature of + 40 °C must
not exceed 50 K. At higher temperatures the gear unit must be shut down immediately
and Siemens customer service consulted.
7.2.6 Gear unit with oil­level monitoring
When the signal "oil level too low" is given, it should be wired in such a way that the
drive motor cannot start and an alarm is triggered. During operation, any active signal
should be bridged.
7.2.7

Heating

Never switch the heating on, unless complete immersion of the rod heater in the oil
bath is ensured. Fire hazard!
If heating elements are installed afterwards the maximum heating capacity
(see Table 7 in item 6.16) on the outer surface of the heating element must not be
exceeded.
The correct setting of the switch points must be checked!
