7.2.6 Oil­level monitoring system
This monitoring is designed as a standstill monitoring (gear‐unit stop) and checks the
level of the oil before the unit is started up. 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 given.
During operation, any active signal should be bridged.
7.2.7 Bearing monitoring (vibration measurement)
If the necessary measures have been made for vibration measurement as
bearing monitoring (see item 5.14), vibration measurements must be taken in
order to obtain initial values and/or standard values for the diagnosis. These
measurements must be recorded and filed.
7.2.8 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 14 in item 5.11) on the outer surface of the heating element must not
be exceeded.
The correct setting of the switch points must be checked!
7.2.9 Checking procedure
The following visual checks must be conducted and recorded when starting up:
□
Oil level
□
Leaktightness of the oil­cooling or oil­supply lines
□
Opening condition of the shut­off valves
□
Effectiveness of the shaft seals
□
Freedom of the rotating parts from contact
The tension pressures and/or pretensioning forces in accordance with item 6.3.2.4 must also be recorded
in this document.
The document must be kept with the instructions.
7.3 Removal from service
• To take the gear unit out of service, first switch off the drive unit.
Secure the drive unit to prevent it from being started up unintentionally.
Attach a warning notice to the start switch!
• In the case of gear units fitted with cooling coil or water oil­coolers, close the stop valves on the water
in­ and outflow pipes. To prevent freezing, drain the water from the cooling coil or the water oil­cooler.
• Start the gear unit and allow it to run briefly (5 to 10 minutes) approx. every 3 weeks (during a shut­down
period no longer than 6 months).
• Treat the gear unit with preservative, see items 7.3.1 and 7.3.2 (before a shut­down period exceeding
6 months).
