Startup

5.1

Starting up the system

Uncontrolled system movement
When starting up, if the magnetic encoder system is part
of a closed loop system whose parameters have not yet
been set, the system may perform uncontrolled
movements. This could result in personal injury and
equipment damage.
► Persons must keep away from the system's
hazardous zones.
► Startup must be performed only by trained technical
personnel.
► Observe the safety instructions of the equipment or
system manufacturer.
1. Check connections for tightness and correct polarity.
Replace damaged connections or devices.
2. Turn on the system.
3. Set zero point (see Section 6.3).
4. Check function.

Status indication/error monitoring

During the measurement signal strength and plausibility of
the absolute position are continuously monitored.
The status of the sensor head is indicated either through
the interface (see Section 6) or the status LED. Depending
on the interface used the status is broken down more
precisely.
The LED indicates the status in three different levels:
LED color Status Description
Green Normal System working normally
Yellow Warning Measuring signal quality is low
Red Error System or measuring error
Warning (indicated by yellow LED)
– Signal quality monitoring: The signal quality drops
below a certain threshold as soon as the sensor head
leaves the recommended working range. The sensor
head is still fully functional, but the application should
still be checked to be on the safe side.
Error (indicated by red LED)
– Plausibility check: If the plausibility check finds an error
in the absolute position or if the signal quality of the
measuring signal is too low, the LED turns red. This
error is reversible and disappears as soon as the
plausibility check is correct again.
– Sensor head outside measuring range: the sensor
head is being operated outside the taught measuring
range limits or the active measuring surface has left the
tape in the direction of travel.
– System error: the sensor head is defective or was
incorrectly configured.
For more information about possible sources of
error, see Section 11.1 on page 26.
It is also possible to read the communication status from
the LED:
LED state Description
Static No communication
Flashing Communication present
