PTR308 Automatic Recoater with Linear Proof Tester Chapter 8: Maintenance
Check Mold End Plates: System with LEDs
The mold end plates have fiber guides that
consist of a vertical and horizontal pin. If the
mold ends or pins collect dirt or recoat material
it could pinch or damage the fiber. These should
be checked prior to each shift for fouling, and, if
required, should be cleaned with a soft cotton
swab soaked in acetone or isopropyl alcohol.
(See Figure 15)
Check/Clean FHB Inserts
The fiber holding block inserts have a rubber
insert that grips the fiber for proof testing. These
should be checked for damage and cleanliness
prior to each shift. If the rubber insert is
damaged or dirty, the fiber may slip prior to
reaching the maximum proof test level. If
Figure 15 Fiber Guides for Systems with LEDs
required, clean the rubber insert with a cotton
swab or lens tissue soaked in isopropyl alcohol.
If rubber insert is damaged it should be replaced.
Note: Do not use acetone to clean the rubber inserts. Repeated cleaning with acetone will damage the rubber.
Note: Do not clean the insert with alcohol when the device is turned ON. The alcohol could be drawn into the
vacuum system, causing damage.
Recoat LEDs
If the recoat LEDs need to be replaced, contact Thorlabs for service.
8.3. Recoat System
Purge
The purge cycle is a process of emptying the recoat material of the Automatic Injector back into the recoat material
bottle and refilling the pump with fresh recoat material drawn from the bottom of the bottle.
If the recoater is not used in a high volume application (less than 200 recoats per month), it is recommended that
the system be purged monthly in order to circulate fresh recoat material into the pump. Running 5 purge cycles is
sufficient to entirely fill the pump with fresh recoat material.
