Table 2: Troubleshooting
With the read heads CES, CEM and CET, two processors each read the transponder in the actuator.
Fastening the actuator in the actuating range with small hysteresis can lead to even slight vibrations
causing the transponder to be read by only one processor (half-reading). This causes the yellow flashing
state to be indicated.
It is recommended to fasten the actuator in the actuating range so that the hysteresis is adequately large
(Fig. 3). If this cannot be implemented, the dual‑channel dependent with filtering module can be used in
the ASIMON software. More detailed information about this can be found in the ASIMON software manual,
which can be opened via the Help function of the ASIMON software.
