D7.1 Monitor/Display Parameters – D**Access and programme structureThe Display Parameters (D***) are separated into several blocks according to the type of operator read onlyinformation. See menu structure in the main body of the manual.All the Display parameters can be accessed directly from the FUNCTION menu by selecting the appropriateidentification number, e.g. D240.ENTER PARAMETER NoD -The live data recalled on the displays are updated continuously by the SMART Communicator every 0.5seconds, and so represents the latest available information from the MSM400 control unit. When monitoringthese parameters the Psion Organiser is active and so will not switch itself off (the normal action after 5minutes without any keyboard input).Additional messages and codes are displayed in a priority order on the LCD when the Display parameters arein use, to indicate exceptional tank conditions or operational problems.D7.2 PROGRAM Parameters – P***Access and Programme StructureThe PROGRAM Parameters are separated into three blocks. These blocks are available for operator access toconfigure the MSM400 control unit as required for the particular application, or adjust the normal mode ofoperation of the unit. Access to all the PROGRAM parameters is made via the PROGRAM menu.The three blocks of PROGRAM parameters are as follows:MODE – The normal operator adjustments equivalent to desludge setup and current input configuration.Parameters P300 - L102.ENGINEER – The more technical operator parameters, establishing response time, alarm delay time and HMI(keypad sound). Parameters P400 - P562.OUTPUT – These allow Relay and current output configure.These PROGRAM parameters are read/write parameters, so that when a particular parameter is recalled itsvalue can be changed by one of three methods – either entering a new value on the blue numeral key pad, oron the alphabet keys for a text entry parameter, or by scrolling sideways. Each of the parameters uses only oneof these methods : sideways scrolling is prompted by the appearance of horizontal arrows on line 3 of theLCD. When the new value is on the display correctly, this is entered using the “EXE” key. The SMARTCommunicator immediately then transmits the change to the MSM400 control unit. If the value is incorrector the operator wants to revert to the original value, the CLEAR/ON key will reinstate the existing parametervalue on the display, without affecting the MSM400 control unit.Within the memory of the Psion Organiser there are four separate registers for each of the PROGRAMParameters. These registers are known as WORKING, SAFE, OFFLINE and DEFAULT, and are furtherdescribed in Section D13.0. All programme changes are made in the WORKING register, and these are thevalues sent to the MSM400 Control unit memory. The display can be cycled through the registers by usingthe MODE key, and the initial letter of the register currently displayed is shown at the right hand end of thesecond line – the same line as the parameter value. Individual parameters can be moved into the WORKINGregister from other registers, by pressing the EXE key whilst the required register value is displayed.49IP258
