6.7 Setting Masters
“Mastering” enables the measurement values at
the sensor output (analog/digital) to be compared
with a known measurement object (master).
This function is primarily used for comparison of
mounting tolerances. The value which is given
during measurement on the sensor output of the
“mastering object“ is the “master value”. This
involves the parallel displacement of the sensor´s
characteristic curve.
Storing of the master value in the sensor:
This master value has to be inserted and stored in
the sensor before mastering. Currently, there are
two possibilities:
1. In the configuration program “ILD1700 Tool“,
see Chap. 10..
2. Command „Set_LIMITS“, see Chap. 8.5.7, (Set
limit values) as digital value in the „master value“.
A detailed description of the calculation, see Chap.
7.3.
Therefore the master value is available even after
a restart of the sensor. Detailed information, see
Chap. 8.5.20 “Enable / Lock the Flash for Setting
Masters and the Mid-Point”. In the case that the
sensor conguration is set to „permanent in ash“,
the master value can permanently be solved in the
sensor in the ILD1700 tool.
The displacement of the characteristic curve
reduces the usable measurement range of the
sensor the further the master value is away from
the master position.
Advice:
In the case of a new ILD1700 sensor 0.5 x measuring
range is set as the master value. Resetting to factory
settings also includes that the master value is set to
0.5 x measuring range.
The action „mastering“ can be activated in three differ-
ent ways:
- Press the button zero/select on the sensor.
Afterwards the red LED flashes “Zero”. The initial
state is reached by a second press.
- External Low-Signal at the input “Zero”:
Connect GND 0.5 … 3 s: SET (mastering),
Connect GND 3 … 6 s: RESET (reset)
- At Firmeware version 6.000 using the command
“SETZero”, see Chap. 8.5.21.
using parameters x = 1 setting ;
using parameters x = 0 reset
IMPORTANT!
“Master“ is only
available in “Switch
mode“ and “Set mid-
point“ is only available
in “Error mode“, see
Chap. 6.5.
“Master“ or “Set mid-
point“ requires that an
object to be measured
is within the measure-
ment range.
„Master“ has an influ-
ence on the analog and
digital output.
