Troubleshooting

Errors
The controller does not receive any
travel information.
The controller does not receive any
travel information at certain points or an
incorrect position is output when
switched on.
Non-linearity is outside the tolerance.
A position substantially larger than null
is output near the start of the magnetic
tape.
Position jump in the range of
movement around the magnetic tape
coding.
The position changes by ≥ 1 mm when
switched on and off.
Error bit = low
Warning bit = low
Data transmission not correct, no
meaningful data values

Possible causes
The required supply voltage is not
available.
The voltage drop is too high.
The sensor head is not properly
connected.
The orientation of the magnetic tape is
incorrect.
The distance between the sensor head
and magnetic tape is incorrect (in some
places).
Some of the magnetic poles of the
magnetic tape are damaged
(mechanically damaged or due to
strong magnets).
The sensor head is not moving parallel
to the magnetic tape (for tolerance, see
Figure 4-1 to Figure 4-6).
The distance/angle between the sensor
head and magnetic tape is too large.
Angle/distance/offset not correct
Angle/distance/offset not correct
Angle/distance/offset not correct
Data inconsistency in sensor head.
Temperature is too high.
No/incorrect terminating resistors on
the control inputs
U B = XX V DC

Troubleshooting/explanation
Check if there is any voltage and that
the BML is correctly connected.
The position measuring system must
have an operating voltage of 5 V ±5%.
Check the pin assignment using the
wiring diagrams.
Check the orientation of the magnetic
tape/sensor head and correct, if
necessary.
Adjust the height/angle of the sensor
head. To check, move the sensor head
by hand over the entire measuring
range.
Exchange the magnetic tape.
Correctly position/orient the sensor
head (see section 4).
Adjust the angle (particularly yaw).
Adjust the angle (particularly yaw).
Adjust the angle (particularly yaw,
check assembly tolerances).
Switch sensor head on/off, check
angle, offset, magnetic tape, for the
magnetic tape orientation, see sections
3 and 4.
Better thermal connection.
Equip controller with terminating
resistors
