14 Troubleshooting

A control unit to which the sensor is connected can often detect errors by
means of the sensor signal. What type of errors are detected depends on the
hardware of the control unit used and the software running on the controller.
The indication or display of an error, e.g. via a display or a diagnostic tool,
depends on the machine concept. If necessary, observe the instruction manual
of the control unit manufacturer.

14.1 Malfunction table for DSA/12 and DSA/20

The Table 8 is intended to support troubleshooting. This table is not exhaustive.
Issues may occur in practice that are not listed here.
Possible cause
Mixing up the connection lines
when connecting the sensor to the
superior control system.
x Sensor was mechanically damaged
from the outside during operation.
x Incorrect or faulty voltage supply:
- Sensor supply voltage is missing.
- Sensor supply voltage is too low.
Remedy
Check the wiring and/or the wiring harness both at
the sensor connector and at the superior control.
Check the sensor for obvious damage:
Cracks in the housing, cracks in the connector
chamber, damage due to external mechanical
influence.
Measure the supply voltage at the contacts of the
sensor and make sure that all contacts in the mating
connector are correctly fitted and latched.
Make sure that the mating connector is connected to
the sensor until latching.
