Introduction The FI-90, a full-function force indicator, is available in four versions: 1) 2) 3) 4) the standard AC powered version an AC lead-acid, rechargeable battery version an alkaline battery version a 12 volt DC version Operations mode provides gross force and peak force readings and allows viewing and configuration of one or more of these parameters: ID number up to two cutoff registers time date Keyboard The key board consists of six keys that control all gross and peak force measuring f

Peak Illuminates when the indicator is in peak-view mode. lb, kg, N Illuminates to show the active unit of measure. Battery Illuminates when the battery voltage is low. "D" cells should be replaced or a lead acid battery recharged. C/Zero Illuminates when the indicator is within ±1/4 division of zero or the force at which the indicator was zeroed.
Powering Up The method of powering up depends on the type of power supply your indicator uses. Look at the back panel of your indicator and the four back panel illustrations below and identify the one that matches your indicator. Then follow the appropriate power-up instructions on the next page.
For the standard AC version (See Figure 2): Plug the power cord into the back of the indicator and connect the cord with an external AC power source. The FI-90 indicator powers up in the same mode it was in when power was removed. For the AC / lead-acid battery version (See Figure 3): The power switch controls your choice of AC power or internal lead-acid battery power.
Measuring Gross Force 1. Power up the indicator. . . 2. Access the gross mode. If the gross annunciator is not illuminated, press GROSS / PEAK once. . . 3. Zero the FI-90 by pressing ZERO / CLEAR (Any stable applied force up to full-rated capacity may be zeroed off). . . 4. Select unit of measure by pressing UNITS. . . 5. Apply force . . . The FI-90 powers up in the same mode it was in when power was removed. The gross annunciator illuminates (See Figure 2). 0 is displayed.
4. View and, if necessary, record the retained peak value. Press PRINT / SELECT to transmit data to a peripheral deviceprinter, chart recorder, or computer or other programmable controllerif interfaced via the RS232 or 20mA option. 5. Clear the last retained peak value by pressing ZERO / CLEAR, and re-apply force. . . 6. You may view increasing force in the gross mode by pressing GROSS / PEAK. . . The retained peak value is released and 0 is momentarily displayed.
3. You now have two choices, A or B: A. Accept the displayed ID by pressing either GROSS / PEAK or PRINT / SELECT. . . GROSS / PEAK takes you directly out to the gross mode. PRINT / SELECT displays ID. Or B. Enter a new ID of up to seven digits. Use the data entry procedure shown in the section, Entering Data with Arrow Keys. Then press PRINT / SELECT. . . The new ID number is accepted and ID is displayed.
2. Start with the left-most digit (in our example, a 6 ). Pressing UP ARROW one depression for each whole number, increment the displayed number up to the desired value. . . 3. Then press LEFT ARROW to bump the 6 a single space to the left and display a 0 in the edit-character position. . . 4. The 0 in the edit-character position is acceptable for our example's second digit, so no depressions of UP ARROW are required for it.
Viewing and Entering Setpoints (Cutoffs) A setpoint cutoff is a force-load value at which an internal electrical connection is broken, causing an external relay to de-energize. Additional relay configurations can turn on or shut off another electrical device. You may configure the FI-90 to accept either one of two types of cutoff: (1) a gross-based setpoint or (2) an increment-based setpoint. A gross-based setpoint is called, simply, a setpoint.
2. Enter a new setpoint value in register #0, using the procedure presented in the section, Entering Data with Arrow Keys. Before you enter any numeric values, specify a negative setpoint, if appropriate for your application. To display a negative sign, "-", use UP ARROW to scroll through all digits and characters until the sign is displayed. Then press LEFT ARROW to place a new edit character in the edit position.
Cutoff Connections The cutoff connector located on the bottom of the indicator is a nine-pin female connector. Figure 7 shows the pin assignments. Signal Name +12v (on 12v units) + Relay voltage Cutoff 0 Cutoff 1 Logic ground Shield Remote input Pin Number #9 #6 #1 #2 #5 #7 #4 Figure 7 Cutoff Connection Pin Assignments Viewing and Setting Time 1. From gross or peak-view mode, press MENU repeatedly until Hour is displayed, then press PRINT / SELECT. . .
3. After the clock is set, you may press PRINT / SELECT to start the clock and return to operations mode menu,. . . or press GROSS / PEAK to return to gross or peak-view mode. . . Hour is displayed and the clock begins. The clock starts at the new time setting. Viewing and Setting the Date 1. From gross or peak-view mode, press MENU repeatedly until dAY is displayed, then press PRINT / SELECT. . . If you enter an incorrect digit, press ZERO / CLEAR key to clear the display one digit at a time.
Transmitting Data Your indicator requires an RS-232 / 20mA output for data transmission. The RS-232 / 20mA connector is located on the bottom of the indicator and is a 9pin male connector. Connect a printer following the pin assignments listed in Figure 8.
Analog Output Option An optional, isolated analog output provides dip-switch selectable output: 15mA, 4-20mA, 10-50mA, 0-5VDC, 0-10VDC. The analog output can be used with programmable controllers, chart recorders, etc. It uses a nine-pin female connector as shown in Figure 10.
Using Test Mode for Indicator Diagnostics Test mode allows you to test various functions of the FI-90. A flowchart of the test mode menu is shown in Figure 11, followed by instructions for getting around in the test mode and executing tests. Figure 11 Flowchart of the Test Mode Menu 1. Enter the test mode from gross or peak-view mode by pressing and holding MENU until tESt is displayed. SEAL or unSEAL is displayed briefly while you hold the key. 2.
Main Displays Viewed in the Test Mode Menu 22 VERSION version - Under version are the Weigh-Tronix part number for the FI-90 force indicator, and the revision number for the software found in your unit. Weigh-Tronix part numbers are divided into two parts: a five-digit prefix and a four-digit dash number. dISPLAY display - From this display: dISPLAY, press PRINT / SELECT and the top row of annunciators turns on. Press PRINT / SELECT again and a dynamic test is run.
