Check system function

Check all functions as follows after assembling the
magnetic encoder system or exchanging the sensor head
or magnetic tape:
1. Switch on the sensor head supply voltage.
2. Check that the count direction of all interfaces
corresponds with the direction of travel, and correct
the controller parameterization if necessary.
3. Move the sensor head along the entire measuring
length and check whether the measurement value
within the range is plausible. No error is allowed to
occur in the data set or to be indicated by the LED.
Troubleshooting steps are described in Section 10.1 on
page 25.

Operating notes

– Check and record the function of the magnetic
encoder system and all associated components on a
regular basis.
– If there are malfunctions in the magnetic encoder
system, take it out of service and secure it against
unauthorized operation (see also Troubleshooting on
page 25).
– Secure the system against unauthorized use.
The BML is an absolute measuring system.
When the operating voltage is switched on, the
absolute position is immediately available
without the need for a reference run. The sensor
head may not be removed in direction Z or Y
from and replaced on the magnetic tape during
operation. An error message is output
immediately if lifted. If the sensor head is
returned, a valid signal is not output until a
movement of approx. 30 mm in direction X has
occurred or after 2 seconds. Leaving and
approaching the magnetic tape in the direction
of travel with a speed from 1 mm/s...5 m/s is
however permitted. After the active surface is
placed above the magnetic tape the error signal
disappears and a valid position value is output.
In the document Interfaces for Magnetic
Encoder System BML there is a checklist for all
relevant actions related to installation and
service.
