How to use CTA correctly…
To avoid misaction caused by interference, please make sure if you isolate the I/O wiring when I/O
wiring and power cable or high-voltage cable in the same wiring tube. If possible, use a separate tube
for the I/O wiring.
Make sure that you place the sensor, other input devices, signal cables and CTA away from the
interference source.
It will require 200ms after CTA is switched on for the activation of the internal power and default
value reset. CTA may not operate normally during this period of time.
