Reassembly
1.) Rethread the roller screw into the internally threaded cylinder (ITC). It is a
multiple start screw, and this is not always easy. DO NOT FORCE THE ROLLER
SCREW INTO THE CYLINDER. It is best to have the actuator vertical with the
open end of the roller screw cylinder facing up. Position the roller screw above
the cylinder so that it is aligned axially with the ITC. Slowly turn the roller screw
1/4 to 1/2 a turn counterclockwise with it in contact with the ITC. This will help to
align the threads on the roller screw with the threads in the ITC. Rotate the roller
screw clockwise and it should begin to thread into the cylinder. If it does not turn
freely, remove it and begin again. When threading the screw into the cylinder, it
will roll freely into the actuator. When it reaches the portion of the cylinder that
contains the motor magnets, the roller screw will be more difficult to turn because
of the magnetic field of the magnets. THIS IS NORMAL. Continue to thread the
roller screw into the cylinder. When it reaches the bottom, it will become difficult
to turn and the motor and bearings will begin to rotate with it. The roller screw is
now fully inserted into the cylinder.
2.) Place a small amount of seal lubricant on the inside surface of the seal/bushing
assembly.
3.) Carefully slide the bushing/seal assembly over the actuator rod end. The seal is
a tight fit on the rod end. Take care not to damage the seal on the threads of the
rod. Rods have a chamfer to provide a lead in for replacement of the seal. The
mounting screws should have a low or medium strength thread locker added,
such as Loctite 222MS.
English
Take caution when installing the gland over the rod and into the actuator
housing. These joints compromise flame paths on the actuator. If parts
become damaged consult Exlar prior to re-installing.
Bulgarian
Обърнете внимание, когато извършвате монтажа на муфата върху оста и в картера
на изпълнителния механизъм. Тези съединения компрометират безопасността от
взрив и запалване на изпълнителния механизъм. Ако се повредят някои части, преди
ремонта се посъветвайте с Exlar.
Croatian
Budite pažljivi pri instalaciji uvodnice preko šipke i u kućište aktuatora. Ti spojevi mogu
ugroziti protupožarne putove unutar aktuatora. U slučaju oštećenja dijelova prije ponovne
instalacije obratite se tvrtki Exlar.
Czech
Věnujte pozornost montáži ucpávky na táhlo a do skříně aktuátoru. Tyto spoje narušují
cesty plamene aktuátoru. Dojde-
li k poškození dílů, před opětovnou montáží to konzultujte
se společností Exlar.
Danish
Vær forsigtig, når pakningen installeres over stangen og i aktivatorhuset. Disse led
kompromitterer flammestier på aktivatoren. Hvis dele bliver beskadigede, skal Exlar
kontaktes inden geninstallering.
