Safeguards and Precautions 1. Read and follow all instructions in this manual carefully, and retain this manual for future reference. 2. Do not use this instrument in any manner inconsistent with these operating instructions or under any conditions that exceed the environmental specifications stated. 3. Be sure the power supplied to this instrument matches the specification indicated on the rear panel of the instrument. 4.
@CH_A/LOEND = 12 (or 1_SEC, HALF) Sets low end time. This allows a min reading of 5 RPM, 60 RPM, or 120 RPM. @CH_A/GATE Show Gate Speed. (Default is 12) @CH_A/GATE = STD (1/100 Second) or FAST (1/1000 second). Sets Gate Speed (Default is 1/100) @DECPT @DECPT = NONE, 1, 2, or 3 Shows the number of decimal places displayed Sets the maximum number of decimal places. @DAC1/ FSCAL @DAC1/FSCAL = xxx.
1.0 OVERVIEW The F2A1X Frequency to Analog Module converts frequency input into an analog voltage (0 to 5Vdc) or current (4 to 20mAdc) output. The output is electrically isolated from the rest of the unit. The input signal may be from an external sensor (measuring RPM for example) or any source of digital signal not exceeding 12 volts.
6.0 OPTIONS AND ACCESSORIES / SENSORS T-5 Reflective Tape - 5 foot (1.5 m) roll, 0.5 inch (10 mm) wide USB Programming Cable with PM Remote Software on CD: Enables the user to program the F2A1X using a PC with USB connection. The software also allows remote monitoring of the RPM using a graphic display or an ExcelTM spreadsheet.
NOTE: The Full scale output settings must have been specified when ordered or may be user programmed using the User Programming Cable. 0.1 to 10 KHz, 5 to 600,000 RPM Accuracy: 0.005% mA Option: 4 to 20 mA out, 16 bit resolution 10Vdc compliance voltage. Zero and full scale settings as specified when ordered or user programmable using USB Programming Cable and PM Remote Software Vdc Option: 0 to 5 Vdc out, 5 mA 16 bit resolution.
4.0 USER PROGRAMMABLE SOFTWARE SETTINGS All the operational settings of the F2A1X Frequency to Analog Module can be set remotely using the PM Remote PC Software and the optional User Programming Cable (UPC). This cable plugs into the unit via the phone jack socket below the SENSOR INPUT terminal block as shown here and into a USB port on the PC. Settings that can be programmed include input scaling, analog output full scale and offset, input pulse polarity and update rate.
There are three jumpers as shown in Figure 4. These are: 3.1 Sensor Power Voltage This jumper adjusts the supply voltage to the external sensor. Can be set as +5Vdc or +10Vdc depending on the sensor used. Factory Default is +5V. 3.2 Figure 3 Signal Source Connection Detail 3.0 USER PROGRAMMABLE HARDWARE SETTINGS There are several settings relating to the sensor input that can be set by the user. The settings are done by moving jumpers on the circuit board inside the housing.
