7.6 Errors

7.6.1 Errors after an initialization run

Following a successful initialization run, only the green LED is lit.
If the red LED is flashing, this indicates an error following an unsuccessful initialization run.
The first error to occur during initialization is shown. If the green LED is lit, the unit had already
been initialized before the current initialization run. If the green LED is flashing, the unit had not
been successfully initialized previously.
The red LED shows errors occuring during initialization as follows:
Error code 1: interval
Error code 2:
etc. up to ...
Error code 8:
etc..
Error code Error
Invalid status of initialization run. Possible
1 → 1 x
cause: EMI (electromagnetic interference).
Sensor malfunction at analogue input AI1:
2 → 2 x
No signal from potentiometer.
3 → 3 x Potentiometer value at AI1 too small.
Possible cause: EMI.
Potentiometer value at AI1 too large.
4 → 4 x
Possible cause: EMI.
Wrong direction of travel
5 → 5 x
Obstruction: potentiometer or motor not moving. Check connections, set N↔S switch to "N",
6 → 6 x
7 → 7 x Stroke too long.
Stroke too short.
8 → 8 x
Following an initialization run, the red LED shows only initialization errors as long as DIP switch
12 is set to 1. This enables a clear differentiation between errors occuring during initialization
and those occuring during normal positioner operation. Setting DIP switch 12 from 1 back to 0
permits the red LED to show any normal operational errors instead of initialization errors which
may have occured.
