Page 6: Product Description
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 two- channel 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.

Page 10: Sensor / Pulse Inputs
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.
Page 11: Analog Output(S)
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.
Page 12: Analog Input (Option Board 1)
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.
Page 13: Batch Controller Inputs (Option Board 3)
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.

Max Total mA Enter the mA to represent the above entered maximum totalizer value. 20mA is the maximum allowable value. LIMIT/ Pulse Output programming Figure 17: Limit/Pulse Output Programming Two relay outputs and an opto coupler frequency output are available on option cards 1 and 2.
Page 30 Cycle Output (pulsed output) Figure 18: Cycle Output The CYCLE OUT limit function provides an incremental output signal for a remote totalizer, typically at a lower resolution and frequency. Assigning a limit to the CYCLE OUT function toggles the state of the limit output whenever the TOTAL increments by the programmed cycle amount.
Page 31: Rate Value
Each Limit can be set to trigger its output based on a certain flow rate or total set point. This is often used to indicate if a flow rate is outside its intended limits or if a certain total value has been reached in a batch application. Rate Value The limit output will be off if the incoming flow rate is below the programed Rate Value and the output will be on if the incoming flow rate is equal to or above the...

WARNING / ALARM AB / BA Value The Warning or Alarm AB / BA limit will activate the selected relay when the respective limit is reached in the Ratio AB and BA menus. Select the Warning or Alarm trigger desired and set the values in the Ratio menus starting on page 35. Frequency Output Programming Figure 22.
Page 33: Linearizer Programming
Linearizer Programming Figure 24. Linearizer Programming The MX 9000 has a 10-point linearizer which can be used to increase the linearity of the flow rate reading. When entering the Linearizer programming mode, the first question asked is if the Linearizer should be activated. If the linearizer has already been programmed, de-activating the linearizer does not erase any previously programmed table values.
Page 34: Quadrature Signal Programming
To clear a previously programmed linearizer table, enter the linearizer table and change Point 1 Freq. to zero (0). After pressing the ENTER button, the MX 9000 will display a warning that all table values will be cleared. If this is correct, press the YES button.
Page 35: System Settings Programming
NOTE: Enabling the quadrature signal display will automatically disable all screens associated with channel B as it is required that when using quadrature signals it can only be with one flow meter. System Settings Programming Figure 26. System Settings Programming The system settings menu allows for the customization of the decimal places and background color of the LCD display during limit operation.
Page 36 Before starting the calibration routine, make sure the analog output is connected to the intended readout equipment.

Page 44: Delay
DELAY This variable sets the delay time for Limit 1 relay (high flow solenoid output) relative to the START input. Typical delays are from 0.00 to 4.00 seconds. This function is used in slow start applications where Limit 2 relay (low flow solenoid output) is energized immediately at a START input and Limit 1 relay (high flow solenoid output) is turned on after the DELAY time.
Page 45: Operation
OPERATION To run a batch, select one of the pre-programmed ones using the batch select switch, then press the start / stop switch. Note that any of the 20 presets that are programmed with 0 for both limits will be skipped. Immediately the low flow output (relay 2) will energize and the display will indicate “RUN”.
