5.6 Measurement range
Band coding:
The absolute coding of MBA511 enables a max.
measurement range of 20480 mm.
Position value (-480.00 ... +20.000 mm)
In order to avoid leaps occurring around the maxi-
mum value at the 0 position, this maximum value is
limited to 20 m. This enables recording of a range of
up to -480 mm in negative travel direction.
6. Trouble shooting
Below there are some typical errors which may oc-
cur during installation and operation:
• Sensor not or incorrectly connected (for pin con-
nection see chapter 4).
• Tolerance for the gap between magnetic sensor and
magnetic strip not observed over the total travel
distance. Sensor touches strip (see chapter 7).
• Cable squeezed / interrupted / cut by sharp edges.
• Sensor's active side not mounted towards the
magnetic strip (see fig. 8).
• Sensor and magnetic strip have been incorrectly
aligned (see chapter 1).
• Magnetic fields near the measuring surface distort
the measuring values. If required, provide for
adequate screening.
• Wrong measuring values due to EMC interferences
(see chapter 4).
7. List of commands / service mode
Parameters: 19200 Baud, no parity, 8 bit, 1 stop
bit, no handshake
Data code: ASCII / Hexadecimal
Value range: 2/3 Byte: 0...65535 / 0...± 2
