7.11Readings and diagnostics parameters

The user can not alter the value of readings or diagnostics parameters within the MONITOR menu.

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

7.11.1 Readings parameters D800 to D834

7.11.1.1Sludge Level - D800

The main process variable, the sludge blanket level in metres (feet – imperial).

Note:

If P629 Level offset is being used, this value will be added or subtracted from the normal sludge blanket level and displayed as D800.

7.11.1.2Target Range - D801

The actual distance from the transducer to the sludge blanket interface in metres (feet – imperial).

7.11.1.3% Current Output - D805 Indicates % of current output

7.11.1.4Current Output - D806

The actual current output in mA.

7.11.1.5Relay Status - D820

This diagnostic parameter indicates the status of all the relays including relay three, the fault relay and relay four, the compressor relay.

The relay status is indicated by a 1 or a 0. A 1 indicates the relay is energised, a 0 indicates the relay is de- energised.

The display shows the state in the following format: 0000

Reading from left to right the first 0 is relay 1, the second 0 is relay 2, the third 0 is relay 3 and the fourth 0 is relay 4.

7.11.1.6RL * Runtime – (RL 1-D821, RL 2-D822, Cleaning time-824)

The total length of time in hours and minutes that a relay has been energised is monitored from this parameter. Entering zero for the hours and minutes will reset the parameter.

7.11.1.7Alarm Report - D830

When an alarm is detected then it can be viewed by accessing this parameter.

Press ￿￿to highlight the first alarm report item. The user can step through the current active alarms using the ￿ and ￿ keys.

7.11.1.8Fault Report - D831

When a fault is detected then it can be viewed by accessing this parameter. In normal operation, the highest priority active fault condition is also displayed in the lower display. Press ￿￿to highlight the first fault report item. The user can scroll through the current active faults using the ￿ and ￿ keys.
