- Page 2 I. Overview The PA2 pulse analyzer was designed to assist the service technician in troubleshooting pulser problems with consoles or card systems. The PA2 performs 3 basic functions: 1. Reads and displays pulse count directly from a contact closure type pulser, electronic open-collector pulser, or active pulser.
- Page 3 If the battery voltage is below 7 volts, replace the battery. After the power up sequence, the PA2 will display a menu depending on the position of the MODE switch. Each mode has different menu options. Rotate the selector knob to the right of the display to change menu options.
- Page 4 V. Operation The PA2 has 3 modes of operation which are selected with the MODE switch to the left of the display. These modes are: Contact Count Powered Count Pulse Output Note: To avoid damaging the PA2 circuitry, make sure that the leads are disconnected before changing the MODE switch position.
- Page 5 On the other hand, if the pulser output is closed when count mode begins, the PA2 will count “1” when the pulser output opens. In this way, the PA2 never triggers the first count when the leads are connected. The count is displayed on the PA2 as Count>00000000.
- Page 6 See the Begin Counting option above for the description. When counting pulses in the powered count mode, the PA2 will detect a change in the pulse input when the voltage between the red and black leads exceeds or falls below 1.5 volts.
- Page 7 When finished, press the selector knob again to return to the menu. Note: When the PA2 is in the contact count mode, the pulse analyzer sends 9 volts DC out on the red lead, and looks for the pulsed 9 volts DC on the black lead. A pulse is triggered if the voltage on the input wire rises above or falls below 1.5 volts DC.
- Page 8 Connect the PA2 red lead to the positive and the black lead to the negative terminal, or to the system’s DC ground. Use the selector knob to select “Begin Counting” and press the selector knob. The count display will appear.
- Page 9 When all pulses have been sent, the display will change to “Output Complete”. Compare the pulses sent by the PA2 with the number of pulses read by the console or card system.
- Page 10 4. Connect PA2 leads to console or card system 5. Select “Begin pulsing” 6. Compare PA2 count with console / card system count Pulse Analyzer Connection Chart The following chart show the correct connection of the pulse analyzer to commonly used pulsers.

- Page 13 On others, it will switch to +12vdc. The + terminal of the PA2 (red wire) should always be connected to the positive side of the inputs and the – terminal (black wire) should connect to the negative side. If you do not see any pulses while testing, try reversing the black and white PA2 wires on the fuel management terminals.
