Startup
5.1 Starting up the system
DANGER
Uncontrolled system movement
When starting up, if the position measuring 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.
Do not check system without assistance!
1. Check connections for tightness and correct polarity.
Replace damaged connections or devices.
2. Turn on the system.
3. Check measured values in the controller and reset if
necessary.
SSI-/BiSS-C interface
Only send clock impulses if there is power in the
position measuring system.
5.2 BAE PD-ML-010-02
(Configuration Tool incl. programming
adapter), accessories
Using the Configuration Tool is strongly recommended to
ensure the correct functioning of the measuring system.
Using the tool is mandatory for BML-S1H_-_6_C-M3FA. If
the sensor head was configured with this tool, the full
working range (see section 4.1) will be available.
For configuration using the Configuration Tool, see
configuration guide.

5.3 Check system function
Check all functions as follows after assembling the position
measuring system or exchanging the sensor head:
1. Switch on the sensor supply voltage.
2. Move the sensor head along the entire measuring
range and check that all signals are output. To do this,
mark the start position, move slowly forward, and then
move back quickly into the start position. Evaluate the
analog and serial output signals with the controller. The
system has been set correctly if the controller shows
the same value as the start value.
3. Switch the system on and off at several positions. The
measured position may only change slightly (< < 1 mm).
4. Check that the count direction corresponds with the
direction of travel.
5.4 Operating notes
– Check and record the function of the position
measuring system and all associated components on a
regular basis.
– If there are malfunctions in the position measuring
system, take it out of service and secure it against
unauthorized operation (see also Troubleshooting on
page 22).
– Secure the system against unauthorized use.
The BML is an absolute measuring system.
When the supply voltage is switched on, the
absolute position is immediately available
without the need for a reference run. The sensor
head may not be removed from and replaced
on the magnetic tape during operation, because
otherwise an error will be transmitted. This error
will only be deleted after the system is switched
on again.
