5.0 PROGRAMMING5.1 The operation of the MSM400 is controlled by means of programmable parameters. These are stored inmemory and may be set by the user to define variables such as calibration scale factors, set points, and modes ofoperation. The parameters are accessed using the keypad, by means of a menu system as shown below. (Parametersmay also be edited remotely using the HART protocol. See Appendix N). For a full listing of the menu structure referto Appendix A1.5.2 Navigation in the menu systemFrom the main display, pressing any key except ESC will enter the menu system. The top level menu contains the listof available menu items:TOGGLE RUNCALIBRATIONSETUPMONITORTo move up and down the list, use the UP and DOWN arrows until the required menu item is highlighted, then usethe ENT or RIGHT arrow key to select it. The presence of additional menu items off the screen is indicated by upand down arrows on the right hand side of the displayThe next level of the menu is then displayed and the required option can again be selected as above.Continue until the required parameter is displayed and select it using the ENT key. (Note that menu groups are inupper case letters, parameters are in upper and lower case.)The parameter may now be modified. Numeric values are edited one digit at a time, the LEFT and RIGHT arrowsselect each digit by highlighting them and the UP and DOWN arrows increment and decrement each digit. Someparameters e.g. “PV Units” are in the form of a list. These are edited in a similar way, selecting with the RIGHT arrowand using the UP and DOWN arrows to scroll through the listWhen the displayed value is correct, press the ENT key to store it.ScrollingWhen a parameter is displayed but no digit is selected, the UP and DOWN arrow keys will scroll to the next parameterin numeric order. This provides an alternative method of accessing parameters without using the menu facility.Example: Relay 1 set point programming.To programme the relay, follow the simple steps shown below;1. To alter any menu option the padlock icon in the top left of the display must be open. This is done using theTOGGLE RUN menu.2. To access TOGGLE RUN from the normal display, press any key except ESC to display the main menu. Thedown arrow (↓) shown on the screen indicates that there are further options.
