Control error codes:
ATTENTION! If an error code is encountered, an audio warning
signal is generated and the red Off signal light goes on in the display
field. First, please try to continue operating by turning the device off
and back on again. If it is still not possible to eliminate an errorafter
an extended wait, please contact our service department. If you do so,
you should always tell us what error code has been encountered. This
simplifies the process of tracking down the error and makes it possible
to form a preliminary opinion.

Interface and outputs

(KS 130 control version only)
The KS 130 control is equipped with a 15-pin SUB-D connector on the rear side
of the device. The pins are assigned in operatin with analog and serial signals.
Analog autput
Voltage values for the speed measurement quantify
are present on the analog pins.
