6 Selecting the Appropriate BML and Controller System (cont.)
6.2 BML with predefined traverse speed (predecessor to the standard BML)
The requirements for your controller
(counting frequency) and for the
traverse speed of your system can
be determined from the BML model
used (see part numbering code).
Note the values from following table
6-2.
Example (see Table 6-2, column 4):
For a BML model with 5 µm
resolution (F-type) and a max.
speed of 1 m/s (type code 1) the
following apply:
- The smallest edge separation
which your controller must be
able to count is 3.0 µs.

Check connections

Caution! The connections have no
protection against polarity reversal
and overvoltage! Before turning on
power, check the connections
carefully to prevent components
from being destroyed by incorrect
connections or overvoltage.
7.2 Turn on system
Note that the system may perform
uncontrolled movements when it is
switched on, in particular when it is
switched on for the first time and if
the length measurement system in
part of a control system for which the
parameters have yet to be set.
Ensure that no hazards can arise
due to such movements.

Check system function

After installing the transducer
system or replacing the sensing
head, check all functions as follows:
1. Turn on power to the sensor
head.
2. Move the sensor head along the
entire measuring range.
3. Check that all signals are output:
for digital BML the LED must
not come on or flash. As soon as
the LED flashes, this means no
signals are being output (see
troubleshooting).
4. Check whether the count
direction agrees with the direction
of travel.
If not, reverse connections A and
/A.

7.4 Regular checking
The functionality of the transducer
system and all its associated
components should be checked
and logged at regular intervals.
7.5 Malfunction
If there is any indication that the
transducer system is not functioning
properly, remove it from service and
secure it against unauthorized use
(see also Troubleshooting).
