7.10 System parameters

These parameters can be used to test the MSL600 hardware.

Note: A full menu structure is shown in section 11.

7.10.1AUTO CYCLE function

The Auto Cycle or Self-Test function has the effect of automatically ramping up the sludge blanket level value between its minimum and maximum values so as to exercise the current output and relays without the actual blanket level changing.

With the unit On-line, this parameter is accessed via SETUP-SYSTEM-TEST-AUTOCYCLE. Once the menu item AUTOCYCLE is entered press ￿￿. The on screen display prompts you to press ￿ to start the AUTOCYCLE.

AUTOCYCLE is stopped by pressing ￿. Press ESC to return to main menu.

A complete cycle is executed in about 100 seconds. It may be paused and re-started using the ￿ arrow key. During Auto Cycle mode, the MSL600 system continues to measure the blanket level in the background.

On exiting the Auto Cycle mode the sludge blanket level immediately takes on the value based on the MSL600 sensor inputs.

7.10.2DISPLAY test

This function allows the user to test all the pixels in the MSL600 display.

The Display Test function displays the product name, full software version number, and exercises all pixels. The MSL600 remains in Display Test mode until the Esc key is pressed. The same data, excluding the test pattern, is displayed at power-up.

7.10.3Current Output test parameters P700 to P702

This function allows the user to test the current output on the MSL600.

7.10.3.14mA Out Adjust - P700

The current output is calibrated in the factory and should not require any adjustment. However, if required, it is possible to adjust the 4mA point using a calibrated meter (see section 5.5).

7.10.3.220mA Out adjust - P701

The current output is calibrated in the factory and should not require any adjustment. However, if required, it is possible to adjust the 20mA point using a calibrated meter (see section 5.5).

7.10.3.3Set Current - P702

It is possible to force the current output to a value to check loop equipment. Any value between 0 and 20mA can be programmed (see section 5.5). When the unit is returned to On Line mode the current output reverts to normal.

7.10.4LOAD DEFAULTS function

The unit can be reset to its factory-default configuration at any time by selecting the Load Defaults menu option. Pressing ￿ loads the default values when in this menu. This action does not change the language setting or the base units selected (metric or imperial).
