During reference/calibration the counter is set to the programmed reference/calibration value (+
offset value when display mode modulo). The display can thus be zeroed, if
reference/calibration and offset value were previously programmed to 0.
8.1 Manual referencing / calibration
Manual reference/calibration can either be made by:

activating a reference/calibration switch according to its function, i. e. RFS/CAL to ground.
Menu item 'TRS:' must be programmed to "hand".

or by pressing key . Therefore menu item 'RESET:' must be programmed to "on", "del.1s"
or "del.3s".

During reference/calibration the counter is set to the programmed reference/calibration value
(+ offset value when display mode modulo) The display can thus be zeroed, if
reference/calibration and offset value were previously programmed to 0.
8.2 Automatic referencing
(Only incremental!)
Automatic referencing is always made via a reference point transmitter, which is automatically
approached at a defined position (reference value). Suitable reference point transmitters are:

mechanical cam switches.

proximity switches with NPN-output (connected to earth).
Referencing condition: (for opening/ closing contact)
Index "lang": Si si index reference switch
Index "kurz": Index reference switch
General information on automatic reference
Electronic linking of the signals from a reference point transmitter (e. g. cam switch or limit
switch) with the index pulse (index marker) of the connected encoder will calibrate the
measuring display, ie. a start position is defined. During mounting of the reference point
transmitter, please adjust the incremental encoder in such a way that the index pulse appears
when the reference point switch is activated.
The contact of the reference point transmitter must only be active for less than one revolution of
the encoder (see
Fig. 3 ).
