conveyor where it is held by the conveyor board stop.
Three Stage Fast In three stage fast mode, the operation is the same as three stage normal mode
with one exception. The second board is transported on to the print station
when the trailing edge of the first board passes the board at right opto situated
at the end of the print station conveyor. This is achieved by the downline
conveyor returning a ‘Busy’ signal back to the centre as soon as it detects that
its ‘Board Available’ input has gone ‘low’, which completes a downline transfer
as far as the print station is concerned.

Rail Width Home
Sensor
The rail width home sensor is used to find the home position of the moving rail
and is described in detail in the Sequences section (Homing Sequence) of this
chapter.
The sensor is mounted on an adjustable bracket which enables the position
between the front and rear rails to be set at 508.5mm - 508.7mm, (measured
between the inside edges of both rails, when the moving rail is in the home
position).
A fine adjustment can be made to the set rail dimension by slackening the
sensor forward securing screw and turning the home sensor adjustment screw
(Rail Home Setting figure refers) in accordance with the table below.
NOTE
Rail width home sensor checks are also required if rail parallelism adjustments
are carried out.
