MSL600

4. Programming

The following sections introduce the main display and use of the keypad (MSL600 only) for programming the MSL600. Password protection to prevent unauthorized access is also discussed.

4.1 Display

The display is a 240 x 128 dot matrix LCD module with full graphics capability and LED back light. The LCD is split into four parts, see Figure (8).

Figure (8): The LCD display layout

•

Upper left

–

In the upper left of the display is an icon representing the transducer and the unit tag

 

 

 

number. The tag number is user programmable via the HMI.

•

Upper right

–

The HMI information is displayed in the upper right of the display. The HMI uses 4 lines

 

 

 

x 20 characters with each character 7 x 5 dots. In normal operation, the actual blanket

 

 

 

level is displayed here.

•

Lower left

–

The lower left of the display shows the sonar echo profile from which the blanket position

 

 

 

is determined.

•

Lower right

–

The lower right of the display shows the blanket level trend at minute intervals over the

 

 

 

last hour.

When the display is in the normal mode, trending is active and the ￿ and ￿ keys enable the user to view the last 12 hours of data, an hour at a time backwards and forwards respectively. The views are labelled with their start and finish times. The sonar echo profile recorded at the corresponding start time is also displayed.

After reaching the oldest data the ￿ key is inoperative. Where no data has been recorded there is a gap in the trend line. A zero value is represented by a line a single-pixel thick. Pressing Esc returns to the real time normal display.

Note: Do not confuse this trending with data logging which is discussed in more detail later.

The LCD has a back light for operator convenience. This has one of 3 modes selectable using the HMI:

•On permanently unless internal temperature too high, in which case automatically off.

•Off permanently unless internal temperature is too low, in which case automatically on.

•Auto - i.e. off until keypad is actuated, in which case on and stay on for, typically, 5 minutes - on for only 10 seconds if internal temperature too high.

The LCD on the MSL600 is supplemented by a single red LED which indicates the health of the unit. The LED flashes every 2 seconds (½Hz) to indicate normal operation, whilst a steady illumination or no illumination indicates a problem.
