Introduction
1.0 Summary and Features
The Edmunds Gages Trendsetter II offers many sophisticated features and benefits for
durable and robust for shop floor operation.
The Trendsetter II is a microprocessor based gaging column that combines a 101 discrete
LED bargraph display for easy visual monitoring of dimensional measurement
characteristics, with an eight digit alpha numeric display for precise size readings and
operator prompting messages. Illuminated range indicators identify which of the eight
inch or eight millimeter ranges have been selected. The tri-color LED bargraph conveys
both measurement size and status. A single rotary entry switch and six dedicated mode
pushbuttons provide all of the operator control functions required.
The unit is housed in a heavy duty reinforced aluminum case with a module bay for
interchangeable plug in modules which will accommodate Edmunds LVDT type gaging
probes or Edmunds and nearly all major brands of air tooling. The rear panel of the
column contains two female DB25 connectors which provide 6 channels for input/output
bussing of analog signals. These connectors also provide various control/status signals
when the I/O accessory board is installed, Edmunds #5911013, sold separately. An RS232C connector allows output of gage results to a data collector. The Trendsetter II will
operate at any supply line voltage between 100 VAC to 240 VAC at either 50 or 60 HZ.
An additional receptacle is provided for power jumper cord connections for multiple
column applications. The serial number with revision letter is identified at the top of the
rear panel of the Trendsetter II. The Trendsetter II allows the user tremendous flexibility
in tailoring the column to match the gaging requirement.

2.7 E8302 (2) Channel LVDT Signal Conditioning Module
The E8302 module is a two-channel signal conditioning amplifier for inductive type
transducers such as LVDTs that converts the outputs of the transducers into a conditioned
signal for the main controller board. The module is mounted in the lower bay of the
Trendsetter II.
The polarity of inputs A and B must be setup using either switches on the original version
of the board or jumpers on the current version of the circuit board. The polarity setting
determines whether the input reads positive or negative when the LVDT tip is depressed.
The input magnification must also be set using jumpers allowing magnification reduction
to be set to 10x for long range transduc ers or 1x for standard transducers.
A jumper matrix on the board allows it to accept signals in or send signals out to the
analog output connector. By placing the jumper pin for the desired signal line on one of
the six buss lines, the signal can now be sent or received by any other units connected to
the buss.
The bussed in signals, C and D, can be added or subtracted using the "SUM/DIFF"
jumpers.
The LVDT module contains a INPUT selection knob. The INPUT selection knob can be
set to A, B, or AB. When set to A the reading of only input A will be displayed on the
bargraph and the alphanumeric display. When set to B the reading of only input B will
be displayed on the bargraph and the alphanumeric display. When set to AB the result of
input A + input B will be displayed. Note: When auxiliary inputs C and/or D utilized,
they will be "summed" together with LVDT inputs A and B.
The LVDT signal conditioning module also contains a ZERO adjustment knob for inputs
A and B, a MAG adjustment screw for the A and B inputs, and a MAG adjustment screw
for inputs C and D bussed in from a separate column or columns.
Power to the column must be turned off prior to installing or removing a signal
conditioning module.
Refer to the Advanced Operation, LVDT Module Setup section for additional
information on jumper settings and see Basic Operation, Setting LVDT Mag & Zero
for additional information on setting Mag and Zero for a particular application.

2.8 E8303 (1) Channel A/E Signal Conditioning Module
The E8303 module is a single channel air/electric amplifier which processes pneumatic
information from the air tooling and delivers a conditioned signal to the controller board
of the Trendsetter II. The module is mounted in the lower bay of the Trendsetter II.
The A/E module also contains a ZERO adjustment knob and a MAG adjustment knob for
initial input setup to accommodate the air tooling used..
The air tooling is connected to the air fitting on the front panel of the module. The
recommended length of air line from the module to the air tool is no more than six feet.
A minimum of 60 psi air must be supplied to the filter/regulator assembly on the rear of
the unit. The regulator is factory set to 44 psi.
The polarity of the input must be setup using jumpers on the circuit board. The polarity
setting determines whether the input reads positive or negative when the air nozzles are
closed off. The input gain must also be set to low, medium, or high use jumpers supplied
on the circuit board. A jumper strip labeled "A OUT" provides the option to select a pin,
1 -6, to output a high level (+/-1.84VDC) signal to the I/O connectors.
Power to the column must be turned off prior to installing or removing a signal
conditioning module.
Refer to the Advanced Operation, A/E Module Setup section for additional
information on jumper settings and see Basic Operation, Setting A/E Mag & Zero
for additional information on setting Mag and Zero for a particular application.
