The Factory 1 Electromagnetic RF fields EN 61000-4-3 2 Level 3; 10 V/m and Field E PROM locations contain the same calibration values when the 80 MHz - 1 GHz IAMA is received from the factory. Therefore, until the IAMA is field scaled, 2 Fast transients (burst) EN 61000-4-4 Level 4; 2 Kv I/O factory and field modes perform identically. See SCALING PROCEDURE for 2 Level 3; 2 Kv power detailed instructions on field programming the IAMA. RF conducted interference EN 61000-4-6 Level 3; 10 V/rms The units can be scaled to any minimum scale and full scale values within the 150 KHz - 80 MHz extent of the selected range. The closer together the minimum and full scale Simulation of cordless telephone ENV 50204 Level 3; 10 V/m values are to each other, the less accurate the signal will be. For example, if the 0 to 1 V input range is selected, and the unit is scaled for 0 to 0.5 V, the signal 900 MHz ± 5 MHz has the same resolution as the 0 to 1 V range. Since this resolution will be two 200 Hz, 50% duty cycle times the percentage of span for 0.5 V, more accuracy can be achieved by using Emissions to EN 50081-2 the 0 to 0.5 V range.

As with the input choices, the process signal output of the modules is DIP 19. WEIGHT: 4.5 oz. (127.57 g) switch selectable. A 1 position DIP switch is used to select between the 1 mA/20 mA output ranges. The maximum output current signal is 22 mA with ≤600 Ω output resistance and the maximum output voltage signal is 11 V with ≥1 KΩ BLOCK DIAGRAM output resistance. ZERO AND SPAN The input zero and span are set by first applying the minimum value then transitioning S1-2 to store that value. Next, the full scale value is applied and the DIP switch transition stores the value. The output scaling is performed in a similar manner but the output is driven to the desired minimum and full scale values by the calibration source applied to the input. S1-1 is used to store the minimum and full scale output values. The span is defined by: span = (full scale - minimum scale). ILLEGAL RANGE SELECTIONS AND CHANGES The ranges should only be selected before power is applied. If an invalid input * Terminal number is dependent on max. input voltage. or output range is selected when power is applied the output is set to approximately 0 VDC and the red LED indicates the error according to Table 1. Power must be removed and valid ranges selected for the IAMA to operate properly.

The 3-Way isolation is a LED indicates a range change according to Table 1, LED Indications and the combination of optical and transformer isolation.

Wiring for a voltage output is connected to terminals 5 (VOUT-) and 6 Terminal 7: 1 VDC max. (VOUT+). Terminal 8: 10 VDC max. Terminal 9: 100 VDC max. Note: Although signals are present at voltage and current outputs at the same time, only the selected range is in calibration at any one time. Example: A 0 to 10 VDC output is selected. The voltage level present at the voltage output terminals is in calibration, but the signal appearing at the current output terminals does not conform to any of the current output ranges. SCALING PROCEDURE The accuracy of the IAMA is dependent on the accuracy of the calibration source and the voltage or current meter used in the scaling process. If an out of range (see Table 1 for LED indications) or illegal (full scale less than minimum scale) scaling is attempted, the factory calibration values will be stored in place of the field values. This will prohibit erroneous operation of the IAMA. The scaling procedure will have to be repeated. 2 The final storage of the zero and full scale values to E PROM is not done until the last transition of the mode/calibration DIP switches (S1-1 or S1-2). Therefore, the scaling can be aborted any time before the full scale value is saved. This is accomplished by cycling power to the IAMA. The IAMA will restore the factory or previous field scaling values at power up depending on the setting of the DIP switches. See Mode Selection for more detailed instructions for selecting factory and field modes at power up. See Table 2 and 3 for the input and output range DIP switch settings. 1.0 INPUT SET-UP USING FACTORY CONFIGURATION 1.1 Remove power. 1.2 Connect signal wires to the correct input terminals based on the maximum signal input.

Select the lowest possible range that will support the desired Step 2.3 maximum signal. Example: if the desired span is 20 mV to 85 mV, the best range selection is 0 to 100 mV. The 0 to 200 mV will also suffice, but the accuracy will be reduced. (0 to 10 VDC range shown). 2.4 Set Input Field/Fact. switch (S1 switch 2) to the off position.

Terminal 6: + Voltage Terminal 5: - Voltage Terminal 4: + Current Terminal 1: - Current 4.7 An input signal is required to complete output scaling. If previous scaled input is used (completed in Step 2.0), Input Field/Fact. switch (S1 switch 2) and Input Range switches (S1 switches 6 through 10) must remain in the same positions. If another signal source is used, set Input Field/Fact. switch (S1 switch 2) to off position and Input Range switches (S1 switches 6 through 10) to the desired input range (See Table 3). 4.8 Connect input signal source to the correct input terminals based on the maximum signal input.

Step 4.12 If the signal is equal to or below the minimum limit of the selected range, the Red LED blinks slowly and the Green LED turns off. Removing power aborts scaling. Start over at Step 4.1. 4.13 Adjust the input signal until the desired * maximum output level is displayed on the volt or current meter. 4.14 Set Output Field/Fact. switch (S1 switch 1) to the on position. Red LED extinguishes and Green LED becomes solid. Your scaled values are now Step 4.14 saved and will be recalled if the Output Field/Fact. switch (S1 switch 1) is in the on position when power is applied. 4.15 Output scaling is complete. * If the minimum output is higher than the maximum output the module reverses its output behaviour accordingly. 6 RECALIBRATING FACTORY STORED VALUES INPUT RECALIBRATION WARNING: Read the complete procedure at least 1.

INSTALLATION The unit is equipped with a universal mounting foot for attachment to standard DIN style mounting rails, including G profile rail according to EN50035 - G32 , and top hat (T) profile rail according to EN50022 - 35 x 7.5 and 35 x 15. The unit should be installed in a location that does not exceed the maximum operating temperature and provides good air circulation. Placing the unit near devices that generate excessive heat should be avoided. T Rail Installation G Rail Installation To install the IAMA on a “T” To install the IAMA on a “G” style rail, angle the module so style DIN rail, angle the module that the top groove of the “foot” so that the upper groove of the is located over the lip of the top “foot” catches under the lip of the rail. Push the module toward the top rail. Push the module toward rail until it snaps into place. To the rail until it snaps into place. remove a module from the rail, To remove a module from the insert a screwdriver into the slot rail, push up on the bottom of the on the bottom of the “foot”, and module while pulling out and pry upwards on the module until away from the rail. it releases from the rail. 7 APPLICATION Cost efficiency measurements of a printing company included the reduction of bulk stock of the various inks used in their printing processes. The company currently had various ink flow and level devices with different current and voltage outputs and wanted to record these measurements into a control room PC. Several IAMA Universal Signal Conditioning Modules were the answer. The IAMA’s universal input allowed for easy signal conditioning of the various output signals to the required PC’s Bus Board 0 to 10 VDC input signal. The factory calibration settings of the IAMA could be used with the devices in which the flow and level pressure was linear to the signal. The IAMA could also be scaled utilizing the field calibration method with the devices where pressure affected the signal slope specifications. In this case, the IAMA’s re-transmitted 0 to 10 VDC output was field calibrated, negating the expense and time required to rewrite the PC’s software parameters. In addition to accepting multiple signal types and field calibration features, the IAMA also provides the necessary electrical isolation between the control room PC and the hazards of the printing floor electrical noise.
