L9100 includes a 100-segment bar display
consisting of rectangular high-intensity
tricolour LED's digitally
programmable as either red, green or
amber. The bar display also
includes 3 digitally programmable marker
LED's. An 8-digit 0.2" high
alpha-numeric display is also included,
and is used for both programming and
part dimension display.
total of 100 inch ranges are provided,
from 1 Thou to 100 Thou; 100
Metric Ranges are provided from 20 to
When engaged, a 5-digit Primary
Security Code prevents unauthorized
access to the programming menus; a
Secondary Security Code when engaged,
prevents access to both the Part
Selection and Automastering functions.
Part Operation: In
one simple step, the operator may select
from 1 of 2 available part
configurations. Each setup has
independent calibration settings,
ranges, and limit and mastering setups
which are stored in the column. No
re-mastering is required when changing
between setup fixtures.
Once Min and Max master values
have been programmed, the operator needs
only to press the <Enter> button
as prompted by the display readout.
The column will automatically
calibrate itself. If an error
occurs in this process (ie incorrect
masters etc.), then an error message
will be displayed and the column will
maintain its original calibration
settings. A master automaster
pushbutton connection (for multiple
columns) is also available on the column
rear. In addition to Min/Max
mastering, the column can also be
set up for Mean mastering.
Indicating Readout (TIR):
When TIR mode is selected, the
column will display the difference
between the maximum and minimum signals,
and will hold that position on the
display until the values are exceeded,
or a reset is performed. This
feature is often used when measuring a
parameter such as 'out-of-round' , when
a part is rotated in a fixture.
TIR may be set to ON either via
the programming menu, or an optional
front-panel mounted switch with reset
pushbutton. TIR may also be reset
via a remote pushbutton, connected to
the rear of the unit. The
Auto-Reset feature, when engaged, will
trigger a TIR reset each time a new part
is placed in the gaging fixture;
the reset is based on the display
position as a result of part replacment,
and incorporates a programmable time
L9100 columns can be programmed to
display measured values either as a
tolerance, or as actual part size, on
the digital display. To display
actual part size, the nominal value of
the part measurement is programmed into
the column, and it is digitally added to
the tolerance measurement before being
sent to the digital display.
L9100 Column Gages have a standard RS232
communications port for interface to
another device. The most common
application of this is for the transfer
and storage of data readings to a
computer. A 9-pin subminerature
'D' connector on the rear of the column
allows connection to a PC using a
standard serial cable.
a reading is taken, the column station
number, column number, and gaged reading
are sent to the serial port according to
an established protocol. A
connector on the rear of the column
provides the interface for connection to
either a 'Read' button, or to relay
contacts in an automated system.
When the contacts are closed, a
reading is transmitted from the serial
multiple columns are used at a gaging
station, they may be 'daisy-chained'
together for serial communications.
Short jumper cables interconnect
the columns at the rear. The
serial cable connects to only the first
column in the chain. When a
reading is taken, all of the columns
transmit their data, one after another
in sequence through the serial port,
thereby requiring only one cable from
the column gaging station to the PC.
software package is available which can
be installed on a PC and receives
incoming data from the columns (up to 4
stations, and 32 columns/station).
The gaged values are stored in a
database along with column and station
numbers and time and date of readings.
The package enables the user to
produce statistical graphs such as x-bar
& R plots and histograms, and has a
menu driven routine for doing
Repeatability & Reproducibility
L9100 column includes several options of
serial protocols which can be selected
to provide interface to other
Outputs: In the
standard configuration, 3 hard-wired
output connections are available on the
column rear for limit status, where the
output is normally 0 volts, and goes to
+5 volts when the status is reached.
Three programmable limit output
types are available for these outputs.
type 1 provides the normal spec limits
of HI, OK and LO through the three
output lines. Output type 2
provides Approach LO, OK, and Approach
HI through the same three output lines.
Output type 3 provides Approach HI
or LO, OK, and Spec Limit HI or LO.
These are all provided as standard
on the L9100.
an option & special order, all 5
status outputs can be brought
individually. These include spec
HI, Approach HI, OK, Approach LO, and
may optionally order L9100 Columns with
relay outputs. When relays are
included, the status connectors on the
rear of the column which are normally
used for the voltage outputs described
above, are instead used for the relay
contact outputs. Relays are
normally open/normally closed contact.
Contact ratings are 2 amps max @
30Vdc or 0.6 amps max @ 120 Vac.
Gaging: Step Gaging
may be performed with the L9100 columns
when data is being sent to a computer
(sing the L9100 Column Data Acquisition
Software, or other custom software).
Step gaging allows groups of
columns at a station to transmit their
data at different times during a gaging
cycle, and yet requires only one serial
connection to the computer from that
station. Each group of columns are
connected by the optional LC0710 Step
