1 - STORAGE
Pjn servo gearboxes can be stored horizontally in a dry place
at a temperature between 0° and 30°C in their original
packaging (for a maximum of one year). (The threads and the
area below the screw heads of the locking clamps are
lubricated with molybdenum disulphide).
The service life of servo gearboxes increasingly depends on
how well they are maintained.
2 - INSTALLATION
RECOMMENDATIONS
Servo gearbox :
For the installation of Pjn servo gearbox, follow the
"Recommendations" chapter in the general manual (ref. 2557).
Servo motor :
For connection of the complete drive system (with brake),
follow the instructions of corresponding maintenance
delivered with the goods in the parcel.
3 - LUBRICATION
The Pjn servo gearbox is supplied as standard lubricated with
an oil with a viscosity of 150 mm
2
/S that is heavy pressure
wear-resistant against the risks of pitting, spalling and
abrasion with a very high natural viscosity index and complete
stability at shearing. (Klüber ref. GH6-150).
You must use an oil of the recommended type.
Please observe the oil quantities specified in the
table opposite.
(Magnetic plugs make filling,
pressure relieving and draining easier, and retain any metallic
particles).
POLYGLYCOL LUBRICANTS CANNOT BE MIXED WITH
MINERAL OR SYNTHETIC LUBRICANTS OF A
DIFFERENT TYPE.
3.1 - Maintenance, draining
It is advisable to carry out initial draining after between 100
and 500 operating hours in order to remove the initial residue
from operation. Subsequent draining should preferably be
carried out every 10,000 hours. For harsh applications,
please consult Leroy-Somer.
Observe the recommended
draining intervals and oil quantities.
3.2 - Plugs position
a - Servo gearboxes have an upper plug for
refilling
and a
lower plug for
draining
. The position of these plugs depends
on the operating position of the servo gearbox, which must be
specified at the time of ordering
.
b - For continuous operation at rated speed, the optional
breather plug must be installed.
After installing the servo gearbox on site, insert the breather
plug in the place of one of the standard plugs and observe the
orientation of the vent hole.
3.3 - Oil capacity (cm

For all other operating positions, follow the quantities
specified in column V3.
