Troubleshooting - Siko MSA511 User Information

head stud (SW2,5) which must be screwed out
up to the stop and then, after approx. 1 second,
entirely screwed in to maintain tightness.
5.6 Measurement range
Band coding:
The absolute coding of MBA511 enables a max.
measurement range of 20480mm.
0
+20479999 +1
Position value (-480,00 ... +20.000mm)
In order to avoid leaps occurring around the maxi-
mum value at the 0 position, this maximum value
is limited to 20m. This enables recording of a ran-
ge of up to -480mm 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
connection 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).
