Solartron Metrology.
2.0 Safety Information
502858 issue 1.1
2.0 Safety Information
Terms in this Manual:
WARNING statements identify conditions or practices that could result in personal injury or loss of life.
CAUTION statements identify conditions or practices that could result in damage to the equipment or other property.
Safety considerations
The SI7500 is completely enclosed and provides no potentially hazardous outputs. Safety considerations are related to power
connections and physical mounting.
WARNING
If the SI7500 falls from its mounting location, serious personal injury or damage to the equipment can result.
Power cord and plug
Do not locate the power cord where it can be walked on or will create a tripping hazard. Connect the 3-wire power plug to only a 3-wire grounded outlet.
Never connect 2-wire to 3-wire adapters to the power cord or remove the third ground wire to fit the plug into a 2-wire electrical outlet. Modifying or
overriding the third-wire ground creates a safety hazard and should not be permitted.

WARNING
Always disconnect the power cord from the source of AC power before unplugging it from the SI7500 power connector. The AC voltage available at
electrical outlets is extremely dangerous and can cause serious injury or death.
Electrical wiring and connections
Perform regular inspections of all connections to the SI7500. Keep connections clean and tight. Locate cables away from moving objects. Do not create
tripping hazards with power cords, input cables and other electrical wiring. Use shielded cables to connect to the parallel, serial RS-232 and RS-485 ports.
Make certain that cables are properly terminated and firmly connected on both ends.
Location and mounting
Mount the SI7500 on a stable surface.
Power surge suppressor
Connect the SI7500 to power through a high-quality power surge suppressor. Surge suppressors limit the amplitude of potentially damaging power line
transients caused by electrical machinery or lightning.
CAUTION
Industrial quality surge suppressors are recommended. Surge suppressors found in inexpensive power strips are insufficient to protect the SI7500 from
damage.

3.1 Functionality Of The SI7500
The SI7500 is a 16 channel advanced digital readout system for performing single or multipoint gauge measurements at very high levels of precision and
accuracy. Dimensional inspection of components can be made using a range of Orbit transducers, encoders and other sensors as part of in-line production
activities or final quality inspection. Measurements can be conducted completely under operator control, or can be semi-automated and conducted in
conjunction with a multipoint fixtured gauge system.
Up to 16 Orbit modules can be assigned
to as many SI7500 channel inputs.
Channel inputs can be algebraically
combined or processed by powerful user
programmed mathematics and control
formulas to display dimensions such as
flatness, volume and runout.
Channel inputs... are processed by formulas... to display dimensions

4.2 Connecting Orbit Hardware
The SI7500 can be connected to a network of up to 16 Orbit modules
via the Orbit RS-485 port on the rear of the instrument. There is no
requirement for an extra power supply or Orbit Interface module.
The Orbit network must be connected to the SI7500 with the 9-way
cable supplied to ensure proper function of the measuring system. If a
longer cable than that enclosed in the box is required, contact Solartron
Metrology for a suitable upgrade.

5.1 Accessing The Setup Menu
The SI7500's settings are modied in a setup menu. This is accessible from the default display screen (for factory settings, this is the DRO screen).
After connecting the SI7500 to Orbit modules, as above, apply power to the unit.
Once the DRO screen is displayed, navigate to the setup menu by pressing the
relevant softkeys for Menu>Setup.
The About screen of the setup menu is now displayed which contains details of the SI7500 unit including rmware
version and serial number.
To navigate the menu, use the cursor keys, as described in section 3.

5.3 Assigning Orbit Modules To Channel Inputs
The ow chart below outlines the procedure to follow in setting up & assigning Orbit modules to SI7500 channel inputs:
Firstly, scroll to the Channel screen from the setup menu.
Select the channel number of choice using the decrement & increment softkeys.
Move the cursor to the “Id” field. Select either a) Teach or b) Entry with the relevant softkey to register the Orbit module in
question. Either of these 2 options will associate a particular Orbit module with one of the SI7500’s input channels.

a) Selecting "Teach" will cause an on-screen message to appear, prompting you to press the OK softkey and then actuate
the relevant module (for a Digital Probe or Linear Encoder, move the probe tip).
If the module input has been successfully read, another on screen message will appear notifying you of the successful
“teaching” of the Orbit module.
b) Selecting "Entry" will bring up the Enter Id screen whereby you can input the Orbit module’s Id (as displayed above the
bar-code on the PIE case, connected to the T-CON).
To enter the Id code, select the desired characters with the cursor keys and use the Enter and Cancel keys to respectively
enter or delete a character. Numerals are written to the address directly from the Numeric keypad. The Id will be displayed
at the top of the screen (underlined in red) as it is written.
Once the complete module Id is displayed at the top of the screen, press the Finish softkey to store the Id and return to
the channel screen. If the module Id has been successfully read, an on-screen message will appear notifying you of the
successful reading of the Orbit module’s information.
Repeat this process until the Id’s of all Orbit modules on the network are assigned to a particular SI7500 input channels.

5.4 Parts, Dimensions, Formulas & Channels
The SI7500 allows for the storage of numerous gauging programs
and their use with common Orbit hardware. This enables one SI7500
and Orbit modules to be used to measure a range or family of similar
components with the same xture or even separate, un-related xtures
(Orbit module numbers permitting).
In the SI7500's terminology these programs are called "Parts" and
contain all the details required to gauge a component including probe
setup, tolerances, data handling details etc.
Each Part can contain up to 16 "Dimensions", these are the features
the xture measures and are what will be displayed by SI7500 as
measurement data.
Dimensions are in turn composed of programmable "Formulas" ranging
from direct channel inputs to complex mathematical formulae.
The diagram on the right demonstrates a simple Part, Dimension and
Formula structure. It also shows how channel inputs are referenced and
manipulated within formulae to generate the Dimension data.

5.6 Creating A Part And Dimensions
The SI7500's factory settings' default Part is 0. To add or change to a different Part, enter the Dimensions screen
of the Setup menu and highlight Part. With the Part eld highlighted, the softkeys can be used to cycle between
existing parts or to create new Parts.
NOTE: Dimensions are visible by default, displayed on the DRO and stored in the database. Dimensions can also
be defined as hidden, for use as variables in formulas and not displayed. Hidden dimensions are not printed on re-
ports or sent to computers as data files. Visible and hidden dimensions use the same naming convention. Pressing
the Visible or Hidden softkey will display either register of dimensions.
A maximum of 16 visible and hidden Dimensions can be created for each Part. To create a Dimension, a 3 character
alpha-numeric label must be entered.
To enter a Dimension label, select a Dimension and press the Label softkey. An Alpha entry screen will be displayed
where the 3 character alpha-numeric label can be entered, using the cursor keys to select alphabetic characters and
the keypad to enter numbers.
It is advisable to create Dimension labels that reect the measurement they correspond to.

5.7 Creating Formulas
Formulas dene SI7500 Dimension outputs using channel inputs from Orbit modules or probes. They can also be used to activate outputs, perform condi-
tional tests, control a sequence of events, semi-automate the measurement process and many other functions.
This section of the guide will demonstrate how to setup a Formula, for more detailed information and a list of Formulas available on the SI7500, please refer
to the SI7500 User Manual (document number 502823).
After creating the necessary Dimensions, navigate to the Formulas screen in the Setup menu.
Press the Right Cursor key to enter the Formula Setup screen and highlight the first dimension. The dimension can
be decremented or incremented by pressing the Dec or Inc Softkey.
