Description of 7-segment display (normal operation "." flashes):
▪ After switch ON the machine " 0 " appears on the display
▪ Display "b" --> BIOS was started.
▪ Display flashes alternatively between "b" and "." --> no application available or unable to start appli-
cation.
▪ Display " -I " and " I- " application was loaded.
▪ "." flashes on the display --> ready for operation.

The Vision processor board is mounted on the gantry
head distributor board. This PCB is used for all four gan-
tries.
The 16 BIT CAN processor is used for various different
functions in the following units:
(see Chapter Communication and Control)
▪ Vision board, communication and control via the CAN
Bus to the Vision computer.
▪ Gantry head distributor, control of head processes
and vacuum

Mechanical Adjustment of the Incremental Encoder
The incremental encoders (read units) at the X and Y axes are mechanically set to a distance of 0.4 mm
+/- 0.1 mm and at the marked height to the incremental scale.
See also "4.2.8 Replacing the X-Axis Incremental Encoder (Read Head) [03047215S-xx]" [➙75] for the
diagram "casting marks on the incremental encoder".

Checking the Zero Pulse Signal
The following description is only needed to check the electrical functions of the incremental encoder.
However, if the incremental encoder has been correctly fitted (mechanically), the unit should work with-
out errors.

NOTICE
► To set this distance, use one or more small plastic disks with a total thickness of 0.4 mm.
► After setting the incremental scale, check the zero pulse and the track signals along the en-
tire travel range.
NOTICE
From 2007, machines will be equipped with a new incremental encoder (read head) (as in
SIPLACE D4). A larger measuring window allows you to compensate contaminants on the in-
cremental scale (up to approx. 3.5 mm).

6.3.1.1 Measuring the Analog Zero Pulse Signal
Measuring the Analog Zero Pulse Signal
Measurement procedure for checking the analog zero pulse and the analog track signals
Measurement Procedure
Measuring the initial zero pulse position
► Oscilloscope settings:
CH1: Analog zero pulse
500 mV / 10 ms
CH2: Digital zero pulse
2 V / 10 ms
This should be triggered at CH1 with a trigger thresh-
old of approx. 2.5 V.
► Connect the measurement tester to the incremental
encoder.
► Main switch ON
► Connect the oscilloscope to the measurement tester.
► Set the measurement adapter to Calibrate oscillo-
scope and position the signal at the top, center of the
screen.
► Set the switch to "Measure".
► Manually move the gantry over the first zero pulse.
► The following picture should appear on the oscillo-
scope.
