Absolute encoder
Attention!
"
Never touch the connection contacts on the position absolute encoder or on the cable! The electronics can be
destroyed by static electricity.
"
You must discharge your own body before touching. This can be done, for example, by touching a conductive,
earthed object (for example bare metal switch cabinet parts) immediately before.
"
Operation of the elevator machine without an absolute encoder is not permissible.
Note:
Removal of the absolute encoder is only possible from the rear. Due to the extremely low failure rate
of the absolute encoder, this does not represent a problem.
