Definitions
If not explicitly stated otherwise, decimal values are given as figures without an extension (e.
g. 1234), binary values are marked after the figure with a b (e. g. 1011b), hexadecimal values
with an h (e. g. 280h). Individual bits of larger logic units are named with their value after a
dot (e. g., CW.9; control word bit 9).
1.3
Intended use
For the further functional description, normal operation of the system with unchanged factory
setting is assumed unless otherwise described.
The present device is an absolute position indicator with integrated Industrial Ethernet
interface and a plug-in connection for MS500H magnetic sensor for direct linear distance
measurement (combined with MB500 magnetic tape) or a supported GS04 hollow shaft sensor
for direct shaft mounting. Indicators, control buttons and interface are only active with
external power supply. The sensor of measurement encoder works magnetically incrementally.
Without an external power supply, encoder changes are recorded with battery support. The
status of the replaceable battery is monitored. A volatile target value can be displayed below
the actual value via the backlit two-line LC display. A direction display (indicator) is displayed
if there is a deviation between the actual value and the target window (target value including
Target Window parameter). The indicator direction indicates in which direction the sensor
must be moved to reach the target window. In addition, the position status of two two-color
LEDs (green and red) is displayed. Device malfunctions or inadmissible operating states are
recorded in an error memory. Since both linear magnet sensors and rotary encoders are used
with the AP20S, a clockwise direction of rotation must be equated with a positive travel path.
The buttons can be used to select various functions and to adapt the device parameters stored
in a non-volatile memory to the application. The actual value can be queried via the interface,
the target value can be changed and all device parameters can be adjusted.
