- Page 2 Agenda • General items to check before trying to determine if there is something defective in the FMS, IS barrier, meter, or wiring. – DIP Switch Settings in FMS – Voltage from FMS – Voltages on IS Barrier • Specific Troubleshooting steps for the: – ...
- Page 3 DIP Switch Settings in FMS • If there are DIP switches in the FMS that set the pulser type as active or passive, set the switches for passive. – Active pulsers supply a voltage to the FMS. – Passive pulsers switch the voltage that is provided by the FMS. • ...
- Page 4 Voltage from FMS • The FMS must provide a voltage to the 900CDP IS barrier. The barrier simply acts as a contact closure type pulser. • The barrier can handle 5 to 170 VAC or VDC. The FMS typically provides around 12 VDC. • ...
- Page 5 Voltage from FMS • If there is no voltage available, double check your DIP switch settings. • Some FMS units do not provide the voltage. In this case, you will need to use a pull-up resistor to supply the voltage as shown in this FuelMaster pulser wiring diagram.
- Page 6 Voltage from FMS • The voltage from the FMS is connected to J4 on the IS barrier as shown below. J4 Connections • Be sure that the pulser common and the voltage wires are connected to the IS barrier as shown. If they are reversed, there will be no pulse.
- Page 7 Voltages on IS Barrier • The IS barrier can be powered by either AC or DC power. – AC power is connected to terminal J3 as shown on the barrier. While the max voltage is 240 VAC, the barrier must have a neutral wire connected.
- Page 8 Voltages on IS Barrier • Voltages on terminal J1 (output to the 900CDP) should be as shown in the table below. S -‐ + J1 Connections Voltage Measured Between Barrier (+) and (-) (S) and (-)

Troubleshooting • Place the FMS in manual mode and leave it in manual mode until you have determined which component or wiring is creating the issue. - Page 10 Step 1 Troubleshooting - FMS • To check the FMS hardware, disconnect the FMS to barrier wires inside the FMS. Be sure you note where the wires were connected! • Take a short wire and strip both ends. Connect one end to the Pulser Common terminal in the FMS.
- Page 11 Step 2 Troubleshooting – FMS to Barrier Wiring • To check the FMS to barrier wiring, disconnect the wires at terminal J4 on the barrier, again taking note of which wire was on which connector. • Manually tap the ends of the two wires together. • ...
- Page 12 Step Troubleshooting – IS Barrier 3 • To check the barrier, disconnect the barrier to meter wiring at terminal J1 on the barrier. Note where the wires are terminated on • Using the short wire with the ends stripped, secure one end to the (-) connection on terminal J1.
- Page 13 Step 4 Troubleshooting – Barrier to Meter Wiring • To check the barrier to meter wiring, disconnect the (S) and (-) wires at the meter (under the faceplate of the meter), again taking note of which wire was on which connector. • ...
- Page 14 Step 5 Troubleshooting – 900CDP Meter • On the 900CDP meter, be aware that if you have the units set to pints, ounces, or user defined, there will be no pulse output. • If everything from the FMS through the barrier to meter wiring checks ok, replace the meter.
