Warnings
Fault detection signal:
Temperature at thermal switch > 100°C (± 5 K)
a)
¬ UaS = Low *
¬ Ausgangssignale weiterhin verfügbar
LED failure or contamination of the graduated disk
b)
¬ UaS = Low (min. 20 ms)
¬ Output signals at high impedance **
c)
d)
Attention: A temperature at the thermo switch of 110° C (± 5 K) switches off the supply voltage.**
* The fault-detection signal is not reset until after the rotary encoder has cooled.
** Operation with position feedback is then no longer possible.
