1. By entering CODE 000100, AP20S is set to the alignment mode (see chapter 3.3.1 ).
Display: 1st line "
ADJUST
"
2nd line "
100
" this value may vary by ±1.
2. When connecting sensor MS500H, it must be moved by a few millimeters in the direction
of the cable outlet (speed <1 cm/s).
When connecting sensor GS04, the shaft must be rotated clockwise by a few millimeters
(speed <<1 U/min).
In the lower line, the value will change in positive direction up to "
103
".
3. The alignment process will be completed when this value is finally exceeded. AP20S has
returned to normal operation and shows the corresponding display. If values above
"
103
" are displayed during alignment, then travel speed must be slowed down during
alignment.
4. It is not unusual that the position value cannot be displayed immediately after alignment
travel and "
FULL
" is displayed instead of the value. The display should be calibrated in
this case (see chapter 3.6 ).
3.6 Calibration
Two steps are required for executing calibration:
1. Write calibration value (see parameter Calibration Value )
2. Execute calibration (reset) (via control keys see chapter 2.4 or control word Bit 0 = 1
see chapter 3.1.2 )
Since the measuring system is an absolute system, calibration is necessary only once with
commissioning. With calibration, the calibration value is adopted for calculation of the actual
value. In the case of calibration (time), the following applies:
Actual value = 0 + calibration value + offset value
Calibration value (see chapter 4.2.4 )
Offset value (see chapter 4.2.5 )
