8.3.2 Alignment Procedure during Installation after Transportation
Misalignment can occur due to transportation or storage state (as in
the case where a clamp is not removed). Be sure to make an alignment
according to the procedure described in this subsection at the first
installation.
8.3.2.1 Preparation
(1) Record the adjustment screw readings of the output coupler
(O.C.), rear mirror (R.M.), and folding mirrors (F.M.).
(2) Collect a burn pattern, and use it as the start state for mode
adjustment. If the mode is good, end the adjustment.
Near (3m) :
Cold mode or Hot mode (Internal discharge for three minutes)
Far :
Cold mode or Hot mode (Internal discharge for three minutes)
8.3.2.2 Adjustment method
(1) For 1000-E
(a) Obtain a maximum power based on FM1.
(b) Obtain a maximum power based on FM3 by using O.C. as
the reference.
(c) Obtain a maximum power based on FM3 by using R.M. as
the reference.
(d) Collect a burn pattern. If the mode is good, end this
procedure. If not, start all over again from step (b). At this
time, collect a burn pattern in each step. If the mode is
finally good, end this procedure.
(2) For C2000-E
(a) Obtain a maximum power based on FM1.
(b) Obtain a maximum power based on FM1 by using O.C. as
the reference.
(c) Obtain a maximum power based on FM1 by using R.M. as
the reference.
(d) Collect a burn pattern. If the mode is good, end this
procedure. If not, start all over again from step (b). At this
time, collect a burn pattern in each step. If the mode is
finally good, end this procedure.
