5.1
Installing the linear translator module
o
Carefully remove the protective cover over the beam input with a small screwdriver.
o
To install the subsystem, insert locating pins into the corresponding holes and attach the
subsystem to the prepared installation surface using screws.
Note:
The subsystem may only be installed using the pins and screws specified by
RAYLASE. Follow the installation drawing supplied.
Only for water cooled deflection units
5.2
Requirements to the cooling water
To avoid destruction of the aluminum housing by pitting, the cooling water must meet the
requirements listed in the following table.
Note regarding cooling circuit:
Avoid pure copper components in the cooling circuit (not
refrigerant cycle) of the cooler used. These lead without suitable additive to pitting in alumi-
num cooling channels.
Note:
Damage caused by pitting is excluded from the warranty.
