(1) Field Change before Aligning [Dip switch 1 Bit 1]
OFF: If gap set starts in X field, the splicer checks cleaved angle only in the X
field, and starts alignment in the X field. Then field changes form X to Y,
and cleaved angle in the Y field is checked. Cleaved angle of the Y field is
checked after alignment in the X field is done.
If gap set starts in Y field, the cleaved angle in both Y and X field before
alignment.
ON: If gap set starts in X field, the splicer checks cleaved angle both X and Y
field. Then alignment starts.
If gap set starts in Y field, procedure is the same as “OFF”.
(2) Discharge in X Field View [Dip Switch 1 Bit 2]
OFF: The splicer discharges in the field which alignment is finished.
ON: The splicer discharges in X field always so that discharge is visible.
(When discharge is done in Y field, discharge is not visible.)
(3) ECF Aligning [Dip Switch 1 Bit 4]
OFF: Not ECF Aligning
ON: ECF Aligning in the case of SM, P2-
∗∗
and P3 mode
Refer to Section 7.4.
