12. Configuration input of the
AEA111/1
As soon as +24VDC are applied to the configura-
tion input, the SSI interface and the electronics
unit for sensing absolute information from the
sensor head are deactivated after a short deboun-
cing delay (~1sec.). This function can be used for
minimizing the unavoidable signal noise on the
sensor connection line and the associated ano-
log sin/cos outputs. This state is not evaluated
if +24VDC are already applied to the configurati-
on input when switching on the AEA111/1 since
otherwise it would not be possible to scan the
absolute position. Changes of the SW1 switches
and on the configuration input are only evaluated
after a startup delay of ~0.5s.
13. Trouble shooting
Below there are some typical errors which may oc-
cur during installation and operation:
The AEA111/1 is not or incorrectly connected
(pin connection see chapter 5).
Tolerance for the gap between magnetic sensor
and magnetic strip not opserved over the total
travel distance. Sensor touches strip.
Cable squeezed/ interrupted / cut by sharp
edges.
Sensor and strip are aligned incorrectly towards
each other.
Wrong measuring values due to EMC interferences
(see chapter 5)
The operating mode set does not correspond with
the hardware connected.
