CPX error group 108 (CPX−MMI: [Encoder error])
No. Message Cause/description Error handling Type
1)
80 Communication with
measuring system/sen
sor interface is disturbed
or measuring system/
sensor interface not
Position measuring system
/ sensor interface was not
detected at switch−on.
·
Exchange the position
measuring system /
sensor interface. Check
cables.
Error level: F2
Reset: N
sensor interface not
available
Communication between
the CMAX and position
measuring system / sensor
interface disturbed.
·
Check the lines of the
axis string, valve and dis
placement encoder/
sensor interface step−by−
step and exchange, if
necessary.
81 Hardware of measuring
system / sensor inter
face is defective Hardware of displacement
encoder / sensor interface
is defective.
·
Replace the displace
ment encoder/sensor
interface. Error level: F2
Reset: N
Error while initialising the
displacement encoder /
sensor interface.
·
Exchange the displace
ment encoder/sensor
interface, check the
firmware version of the
CMAX.
82 Invalid position values or
measuring system error DGCI: No magnet present.
·
Check the magnet on
the displacement en
coder. Exchange the
magnet holder, if
necessary. Error level: F2
Reset: F
DGCI: Several magnets
present.
·
Make sure of the follow
ing: No external magnets
are allowed in the direct
proximity of the dis
placement encoder.
DGCI: Multiple pulses (e.g.
due to vibrations).
·
Check the structure.
·
Avoid vibrations.
DNCI: Sensor error.
·
Exchange the sensor
head in the DNCI, if
necessary.
Potentiometer: Operating
voltage drops under 12 V.
·
Check the operating
voltage, check cables
for short circuit and
corrosion.
