4050 Multi-Input Linear Flow Computer 1.INTRODUCTION TO THE LINEAR MULTI-FLOW COMPUTER (COX) MODEL 4050 Designed to meet the ever-changing requirements of flow metering, the Multi-flow computer can be tailored to virtually any flow application. It is designed to accept up to 3 meters and correct for temperature changes and produce a usable output in whatever flow units you require. The 4050 is designed to work with manifold systems and switches relays that are adjustable at which point they trigger.
050 Multi-Input Linear Flow Computer 2.SPECIFICATIONS Frequency: 32 point Linearization curve of frequency/viscosity versus counts per units measured (gallons, litres; etc) by interpolation between points and, by extrapolation, from the first and last two points of the curve. An engineering factor is included for the conversion of units. Frequency range: The default range is 0.5hertz to 65kHz with accuracy +/- 0.002Hz +/- least significant digit.
4050 Multi-Input Linear Flow Computer Working Displays (when COX 4050 is powered on) Refer to programming helper for additional assistance. When the unit is powered up the serial number is displayed for approximately 5 seconds then the first display or the right (Æ) can be used to toggle between the line is shown. The left direction key (Å) Primary Displays (see table below) and the Secondary Displays (see table below). A message is momentarily displayed indicating which section is selected.
4050 Multi-Input Linear Flow Computer 3. PROGRAMMING THE COX 4050 Entering The Programming Mode Press the right arrow key until Secondary is displayed. Press the alter key and.’CODE ****’ will be displayed. A four-digit code can now be entered (serial number). On each press of a key the ‘*’ will change to ‘+’ in sequence from left to right. When all four ‘*’ have been set the code is automatically checked.
4050 Multi-Input Linear Flow Computer 4. PROGRAMMING THE IDENTS AND UNIT LABELS (L/M, PPH, ETC) 1) When in any mode, select the display to be altered using the ÇÈ keys. Note if you are a curve menu you change the units only, this will change all points in that curve. 2) Press the SHIFT key followed by the EXP/UNIT key and the cursor will begin to flash at the far right hand side of the display.
4050 Multi-Input Linear Flow Computer CHn Setup To set up a frequency channel the following will apply, however some items are optional and may not appear in your specific application. Display shows CHn SETUP, pressing alter and using the ÇÈ will show options. Use ALTER to change the values. FRQ CUT OFF VOL CUT OFF MASS CUT OFF TIME BASE UP DATE TIME FRQ CONSTANT VOL FACTOR MASS FACTOR ALPHA CAL_TEMP When below this value of Frequency then FRQ = 0.0 When below this value of volume flow then Vol Flow = 0.

FRONT PANEL TEST MODE By pressing the ÅÆ at the same time the front panel set up and test mode are entered. The display will show the following options by pressing the ÇÈ.
4050 Multi-Input Linear Flow Computer 8. RS232 / RS485 Command Structure. Viewing data from the Multiflow; All data is sent and received as ASCII HEX pairs, the maths used in PIC Hex format, 2 example routines are included to convert this data into PC or ASCII strings. The PIC Hex format is always 4 bytes and represents a 32-bit floating-point number system. To read data use the following format. Description ID View Hub/Slot Reg/Mem Slot Address No.

4050 Multi-Input Linear Flow Computer 9. SPECIAL OPTIONS (Under Secondary) Setting RTC Setting the real time clock. When either the time or the date is viewed pressing ALTER will enable the user to set the time/date. Manifold ON/OFF When this display is showing, pressing ALTER on the IR keyboard will toggle this selection, ON or OFF. When off a manual option is enabled. This option allows the user to set the machine up for multiple meters and a relay state change at a particular set points.
