Dear K Pichan,
The encoder is no problem to work under raining condition just like others RTG….
But for the benefit of doubt and we do not want to further argue on this case. Please inform PAT we will send a new encoder to them as a goodwill.
For TCI, please submit a warranty claim form to us for documents purpose. (please advise can we send to your TCI office?)
Please note parts number of encoder is JP104231, QTY: 1pc.
Regards
