Chapter 2: Installation and Removal Procedures and Notes • Tools Needed You will need the following tools to install your MPX level sensor: • Wrench sized appropriately for MPX mounting • Wrench sized appropriately for conduit connections • Flat-head screwdriver for wire terminals •...
Taper IMPORTANT: Floats must be oriented proper- ly on the stem, or sensor readings will be inac- curate and unreliable. Untapered floats will have a sticker indicating the top of the float. Remove sticker prior to use. Figure 2.1 IMPORTANT: MPX level sensor MUST be installed according to drawing 9003468 (Haz- ...
• Removal Instructions Removing your MPX level sensor from service should be done with care. • If the floats on your sensor fit through the mounting hole, carefully lift the entire sensor assembly out of and away from the vessel. •...
If your monitoring equipment (PLC, etc.) can be configured to interpret the 4-20 mA output(s) of the MPX as volume, then the MPX can be configured accordingly via APG Modbus. See MPX-E/R2 & MPX-E/R3 Modbus Register Lists on pages 19 and 20.

• MPX-E/R4 Modbus Sensor Parameters 40401 - Units Determines the units of measure for the calculated reading when Application Type is set to 0, 1, or 7. 1 = Feet 2 = Inches 3 = Meters 40402 - Application Type Determines the type of calculated reading performed by the sensor.
Page 20
40405 - Maximum Distance (Factory Calibrated) Sets the distance (beginning from the Zero Reference) to the point where the sensor will stop looking for float signals, usually the bottom of the stem. A float beyond the Maximum Distance value will not be detect- 40406 - Full Distance Sets the positive distance (beginning from the sensor Zero Reference) to the point where the monitored vessel is considered full.
Page 21
40413 - Filter Window (Factory Calibrated) Determines the physical range (0 - 10,364 mm) of qualified received signals, based on the current raw reading. Signals beyond the +/- Filter Window range of the current reading will not qualify unless the average moves.
Page 22
40417 - Offset (Factory Calibrated) Sets the Zero Reference of the sensor, the point from which the calculated distance is measured. 40418 - Pre filter Defines the physical range (0 - 10,364 mm) of the start up (pre-filter) window. Four sample readings must be found within the Pre filter window for the MPX sensor to successfully start up.
Used to calibrate bottom float reading (-10,364 - 10,364 mm). 40425 - Gain Offset (Factory Calibrated) Used to move the centerline of the float response signal to optimize signal strength (0 - 255). • APG Modbus Register Lists for MPX-E/R2 and MPX-E/R3 Input Registers (0x04) Register...

40404 - Decimal Place Determines the number of decimal places included in the Calculated Reading(s). For MPX-E/R2 and MPX-E/ R3, this is seen only when using APG Modbus to program the MPX. This setting does not affect the 4-20 mA output.
Page 26
40405 - Maximum Distance (Factory Calibrated) Sets the distance (beginning from the Zero Reference) to the point where the sensor will stop looking for float signals, usually the bottom of the stem. A float beyond the Maximum Distance value will not be detect- 40406 - Full Distance Sets the positive distance (beginning from the sensor Zero Reference) to the point where the monitored vessel is considered full.
Page 27
40412 - Averaging (Factory Calibrated) Sets the number of qualified received float signals to average for the raw reading. Qualified received signals are placed in a first-in, first-out buffer, the contents of which are averaged for the raw reading. The larger the number of qualified received signals being averaged, the smoother the reading will be, and the slower the reading will be to react to quickly changing targets.
Page 28
40416 - Multiplier (Factory Calibrated) Calibrates the distance reading span. The Multiplier is shown by the values 1 - 1999, but these values are understood to represent 0.001 - 1.999. The default of 1000 (i.e. 1.000) is used for most applications. 40417 - Offset (Factory Calibrated) Sets the Zero Reference of the sensor, the point from which the calculated distance is measured.

40423 - 1st Float Offset (Factory Calibrated) Used to calibrate top float reading (-10,364 - 10,364 mm). 40424 - 2nd Float Offset (Factory Calibrated) Used to calibrate bottom float reading (-10,364 - 10,364 mm). 40425 - Gain Offset (Factory Calibrated) Used to move the centerline of the float response signal to optimize signal strength (0 - 255).
