4.11 Electrical installation of the incremental encoder (optional)
This option is (can be) used for measuring the accurate car position. The incremental encoder is mounted
on the shaft and is synchron with the rope pulley.
This encoder is delivered with cable but without plug.
This encoder should only be used as a redundant positioning sensor in combination with a leading
encoder placed e.g. on the elevator drive.
This encoder kann be ordered with a power supply of 5 VDC (not short-circuit protected) or 10-30 VDC
(short-circuit protected).
