7.1 Auto-test
In the main page of the operator software OS3.x, several items are available in
the OUTPUTS box.
When the SELFTEST PASSED item lights red, this indicates that the unit has
initialized correctly and is ready to work. STATUS SSI-CLK and STATUS SSI-DATA
items indicate that the clock and data lines work correctly (red = status is ok)

.
It may happen that, because of the update cycle of your PC, indicators in the
OUTPUTS box blink. However, you should see “predominant red” items when the
lines operate properly.
7.2 OUTPUT VALUE box
When the encoder position is changing, the bar in the OUTPUT VALUE box must
show increasing or decreasing encoder values. Should the color bar or the
percentage display jump or hunt, please check once more for correct setting of
the DIL switch.
7.3 HOLD key
The HOLD key operates in parallel to the hardware input terminal 10 HOLD and
allows freezing the parallel output from the PC screen. Indicator in the RS field
of the INPUTS box indicates that the HOLD function is active, either by software
or by hardware command.
2 Testing the clock lines is primarily useful with Slave operation. Though the test works
also in Master mode, the result is only intended to show that the internal generation of the
clock works properly. However, in Master mode, this test cannot indicate faulty clock drivers or
bad wiring of the clock lines.
