Unpacking
Separate the MX 9000 Flow Monitor from packaging materials and check for any visual signs of damage. If you determine there are damages caused by shipping, file a claim with the shipping company. If the flow monitor appears to have been improperly assembled or does not operate properly, return it for replacement or repair (see Limited Warranty information at the end of this manual).
CAUTION: Before connecting, programming, or operating the MX 9000 Flow Monitor, read this manual.
Quick Guide
CAUTION: As with any precision-engineered device, always operate the MX 9000 in accordance with the manufacturer’s instructions.
Connect to Sensor
You will connect three wires from the sensor(s) to the back of the MX 9000: An electrical power wire a signal wire, and a ground wire.
NOTICE: Dual input models use two sensors (terminals for sensor 2). Insert the stripped end of the red wire into lower terminal #3 (6) and use a screwdriver to secure. Insert the stripped end of the white wire into lower terminal #4 (7) and the stripped end of the black wire into lower terminal #5 (8). Use a screwdriver (push / release) to secure these wires with the spring terminals.
Connect to Power
Insert the leads from the 120VAC adaptor into terminals 1 & 2 of the lower block. Plug the adaptor into a wall receptacle. If you are supplying power from a DC source, insert the positive lead into terminal #1 and the negative lead to terminal #2. DC input should be from 18 to 24 volts.
Basic Key Denitions
The MX 9000 has four keys for data input and programming:
• DOWN / NO
• UP / YES
• SELECT / RESET
• ENTER / EXIT
4
Use the SELECT key to move the cursor to the digit you would like to change or reset the total values, use the UP and DOWN keys to change between screens or increase or decrease the value as desired, and use the ENTER key to enter the information.
Programming and Data Entry
Upon power up, move to the screen that you wish to adjust. Hold the ENTER key in for 3 seconds and screen will change to programming mode. Follow screen prompts.
When in programming mode, numerical values are underlined or you are prompted to answer YES or NO. Use the SELECT key to move between characters then the DOWN / UP keys to change. Press ENTER to store the value. Use YES / NO to enter other setup functions and EXIT when completed. See Programming the MX 9000 beginning on page 21 for complete details.

Product Description
The MX 9000 Flow Monitor is a versatile, multi-functional device that helps you track rate, flow, limit, ratio, and other variables. The unit’s multicolor back-lighted LCD display is easy-to-read with up to 22 different display modes available, depending on model. The standard unit is one channel, but the optional two­channel version allows you to monitor dual flows and display them in a number of ways: separately, as a sum (for example in total material use), as a difference (as in fuel consumption), or as a ratio of product A/product B. You can also use the MX 9000 to detect bi-directional flow when A and B channel signals are available from a single flow meter. Other capabilities include the capacity to monitor data and program the unit remotely. Four model variations give the MX 9000 the capability of performing limit, warning and alarm duties and batching.
Principle of Operation
After first making connections to the power source and to flow transmitter input and output, you can choose up to 22 display modes. These include rates, totals, ratios, limits and others, based on the model purchased. Then input k­factor values, the required engineering units, gate times, limits, etc. A 20 point linearizer is built-in for added display accuracy. You may also program other values such as warning/alarm limits and ratios, depending on model.

Sensor / Pulse Inputs
Pulse inputs are opto isolated and come referenced to signal ground. Regulated +15 VDC at 50mA max is available for powering each sensor. Inputs can also be isolated from the control power by cutting CT1 or CT2 with a sharp knife but then the internal +15 VDC supply is not available. Minimum input voltage is 5 VDC peak for pulses.
Figure 2: Sensor/Pulse Inputs
Reset Input
Opto-isolated external reset input will trigger the MX 9000 to reset the totalizer(s) when the input sees a momentary transition from low (ground) to high (near supply). Reset input can be isolated from internal ground by cutting CT3 with a sharp knife.
Figure 3: Reset Input
10
Analog Output(s)
The isolated 16-bit 4-20mA output(s) can be wired for use with Loop powered inputs or for ground referenced inputs. The analog signal has an internal LED in series which varies in intensity as the mA signal varies. This can be used for troubleshooting purposes. When using the analog signal with inputs used with loop powered signals, it is important to note that the MX 9000 requires an external power supply to power the loop as shown below.
Figure 4: Analog Outputs
Frequency Output (option boards 1 and 2)
An opto-isolated NPN open-collector output can sink or source depending on connection. Attention must be paid to polarity of connections. Limit circuit current to 50 mA and 30 VDC for this circuit.
Figure 5: Frequency Output
Relay Outputs
Two form C relay outputs are available on option boards 1 and 2. They are programmed by the limit screens as to the function of each. See Relay Contact Ratings on page 10 for limits.
11
Figure 6: Relay Outputs
Analog Input (option board 1)
The analog input is available on option board 1. It can be configured for either a 4-20 mA input or a 0-5 or 0-10 VDC input. The input is referenced to the system common. Programming of the input is done using JP1. For 4-20 mA, use jumper pins 1&3 and 2&4. For 0-5 VDC, use jumper pins 3&5 and 4&6. For 0-10 VDC, use jumper pins 3&5 only. Pins are identified on the printed circuit board. Remove back cover to access.
Figure 7: Analog Input
120/240 VAC Input (option board 2)
The line voltage input is available on option board 2. It can be configured for 120 or 240 volt input using jumper pins 1. For 120 volt input jumper both sets of outside pins (see decal on board). For 240 volt input jumper only the center two pins (see decal). NOTE – board is factory set for 120 volt input.
12
Figure 8: 120/240 VAC Input
Batch Controller Inputs (option board 3)
Five inputs are available for remote control of the batch process. You must have ordered the batch model to access these inputs (MX9-B). A 15 VDC output is provided as a supply for the inputs. Program / Run uses a maintained contact (switch), and the other inputs require momentary signals.

2. Line 2 shows the unique serial number of the unit.
3. Line 3 shows the firmware version of the unit
Pushing the SELECT button on the LOGO screen will show the actual model number of the MX 9000. As the features vary with the model, please make a note of this while reading through this manual.
Rate Screens
RATE A (B)
600.00 GPM
The RATE screen displays the flow rate of A or B in the programmed engineering units. If the linearizer is active, ‘LN’ shows in lower left corner. If the Gate Time filter is active, ‘GT’ shows in lower right corner.
Total / Grand Total Screens
TOTAL A (B)
6000 GAL
15
The TOTAL screen displays the flow total of A or B in programmed engineering units. Pressing the RESET button resets the value back to zero (0). The Total can also be reset remotely by connecting a momentary voltage to the external RESET input.
GRAND TOTAL A (B)
6000 GAL
The GRAND TOTAL screen can be accessed using the ENTER button from the TOTAL screen. To reset this total pressing the RESET button will request the user to enter a password at this point. Use the UP – DOWN – SELECT buttons to enter the password code of “53126”. Then press the RESET button which will reset the grand total value back to zero (0).
Note that both grand totals must be reset independent of one another.
The STATUS screen is a raw data display of the current major properties of

the monitor. The rates are shown as Hz, total in pulses, limits as on or off and current loop output (main loop only) in programmed mA DC.
NOTE: The Gate Time lter and linearizer, if acve, do not aect the ow rate value in the STATUS
screen.
This is the raw incoming frequency. The mA shown is not a direct reading of the loop current if there are other problems outside of the controller such as a broken wire or defective loop power source.
NOTE: Because the mA value is an actual signal output, it is aected by the Gate Time and linearizer, if acvated.
