WARNING
To ensure safety and functionality, the person speci-
fied by the operator is required to inspect certain
areas of the centralized lubrication system prior to
initial commissioning. Any detected deficiencies must
be reported immediately to the supervisor and rem-
edied prior to initial commissioning.
The correction of deficiencies must be done exclu-
sively by a specialist in maintenance/servicing in po-
tentially explosive atmospheres.
No potentially explosive atmosphere may be present
during initial commissioning.
7.1 Commissioning
IMPORTANT NOTE
Different lubricants must not be mixed together. Doing so can
cause damage and require costly and complicated cleaning of the
gerotor pump unit/the lubrication system.
It is recommended that an indication of the lubricant in use be at-
tached to the lubricant reservoir (provided by customer) in order
to prevent accidental mixing of lubricants.
WARNING
Hazard due to excessively low or no lubricant
The gerotor pump unit may only be commissioned
and operated with an oil supply; the gerotor pump must
not run dry.
The lubricant fill level in the lubricant reservoir should be
subjected to visual inspection on a regular basis.
Inspect all electrical and hydraulic connections before initial com-
missioning of the gerotor pump unit.
The intake and return lines in the lubricant reservoir must be below
the minimum lubricant level in all operating states.
• Place an oil tray under the gerotor pump unit.
• -See operating instructions from system manufacturer, Chapter
“System ventilation”
• Prefill the pump unit with filtered lubricant via the suction or
pressure port.
•
Vent the pump unit according to the operating instructions from
the system manufacturer.
If switchable or automatic venting is not available, the gerotor pump
unit must be manually vented as described below.
• Switch the centralized lubrication system to pressureless circula-
tion mode according to the operating instructions from the sys-
tem manufacturer.
• Disconnect the pressure port.
• Prefill the gerotor pump unit with oil via the pressure port and
briefly switch the unit on and off in jogging mode.
• Repeat the procedure until bubble-free lubricant discharges.
• Firmly reconnect the pressure port.
The process of venting the centralized lubrication system can be
facilitated by filling long pipe sections before connecting to the lubri-
cation point.
•
Allowing the gerotor pump unit to run until bubble-free and
foam-free lubricant discharges at the end of the lubricant lines.
Ensure that the pump does not run dry in the process.
•
Turn off the gerotor pump unit.
WARNING
Explosion hazard
The lubricant’s ignition temperature has to be at least
50 kelvin above the maximum permissible surface
temperature.
