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 Shows 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 @DAC1/ FSCAL @DAC1/FSCAL = xxx.xx @DAC1/0SCAL @DAC1/0SCAL = xxx.xx @OUTPT @OUTPT = POS or NEG 11 OVERVIEW ..................................................................................... 1 INSTALLATION and POWER .............
OVERVIEW Appendix A - Serial Programming Commands The ACT-1B is an economical and easy to use digital tachometer that displays rotational speed directly in RPM or RPS on a 5-digit red 0.56” high LED display using a speed sensor providing a single (or multiple) pulse(s) per revolution. The number of pulses per rev is factory set at time of ordering and can be user programmed from 1 to 999 using the optional USB Programming Cable and PM Remote Software.
ACCESSORIES / SENSORS Installation T-5 Remove the mounting clips, if fitted, and install the unit into the panel from the front. From the rear of the unit, install the mounting clips on each side and tighten the mounting screws against the rear of the panel. 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 ACT-1B using a PC with USB connection.
USB Programming Cable and Software The 3.5 mm connection “hole” in the center bottom of the rear panel is for the optional USB Programming Cable (p/n 6180-031), which comes with Windows ™ compatible PM (Panel Meter) Remote Software on CD. The cable and software combination allows the user to configure: operation mode, analog output scaling, decimal places, display update rate and pulses per input. The user can also view real time data in digital format and/or through Microsoft® Excel.

Current Output Option (IO) Analog Output Option (AO) The current output is 4 to 20 mA. This output is a current source and has a 12 Vdc internal compliance voltage. (Optional 24 Vdc may be ordered). The analog output is 0 to 5 Vdc. Typical connections are as follows: (See Figure 4.) Connect the Positive side of the signal to the terminal marked OUT, and the Return side of the signal to the terminal marked COM.
