il will settle around the correct oil level. Measure the oil sump temperature ( Page after the gear unit has run in. Check the tightness of the shaft seal on the gear unit ( Page . Check that all rotating parts are free to move. Check whether the shutoff valves are open. Check that all of the oil drain valves are closed. Ensure that all of the other shutoff valves are open. Check that the connecting pipes are firmly seated and tight. Gear unit with bearing monitoring based on vibration measurement: Measure the vibra- tion levels of the rolling-contact bearings ( Page to create initial and comparison val- ues. Record and archive these values. Bypass the pressure monitor signal for around 2seconds during commissioning. This is necessary as the pressure in the gear unit must first stabilise. Limit the period of no-load operation on the gear unit to minimum. If the gear unit does not heat up because the load applied is too low, throttle the cooling water supply. in or- der to reduce the formation of oil foam. Commissioning 6.2 Measures during commissioning A5-0 en Edition 0/2 6More information You can find additional information on the topic of oil in Instructions7, which are part of the complete documentation of the gear unit. More information about the oil supply system can be found in the oil supply system instruc- tions contained in the complete documentation for the gear unit. 6.2.1 Initial test run 6.2 Measures during commissioning Restrict the period of no-load operation of the gear unit to maximum of 1minutes. When the gear unit is put into operation for the first time, monitor it closely for the first two hours in operation under load so that you can shut down the main motor immediately if un- foreseeable complications develop. 6.2.2 Gear unit with heating 6.2 Measures during commissioning Please observe the following measures to commission the gear unit with heating: Ensure that the heating elements are not exposed. Check the switching points of the
