P-TYPE SEPARATION SYSTEM PARAMETER LIST 1 PARAMETER SETTING

1 Parameter Setting

The parameters are set in the operator panel for the different separator systems, and for different conditions within the systems.

There are three parameter types: Installation, Process, and Factory Set parameters.

The parameters are initially set at installation. The process parameters can also be set as required during operation.

Parameters not in use are not displayed.

The parameter list in this booklet is valid for PA and PU systems.

General principle

The ‘ENTER’ button is used to:

– enter into a parameter list

– enter into a parameter

– accept/store a new parameter value.

The ‘+’ or the ‘–’ buttons are used to change the value flashing in the display window.

To change parameters, proceed as follows:

1 Push the ‘ENTER’ button.

‘Time to discharge P1 60’ is shown. ‘P1 is the parameter, and ‘60’ is the set value.

The ‘1’ of the ‘P1’ is flashing.

2 Push the ‘+’ button until the number of the parameter you wish to program appears in the display window.

The chosen parameter number is now flashing.

3 Push the ‘ENTER’ button.

The chosen parameter number is now shown on the left side in the display. The parameter value is shown flashing on the right side of the display.

4 Push the ‘+’ or ‘–’ button to change the parameter value.

5 Push the ‘ENTER’ button. The new value is stored.

The parameter number is now flashing.

6 Push the ‘+’ or ‘–’ button to go to the next parameter to be changed.

7 To leave the list, push the ‘+’ and the ‘–’ buttons at the same time. The display shows ‘Standst.’ or, when in operation, the trigger value to the left, and time remaining to discharge on the right.

The installation parameters must be set before the initial start-up and before process parameters are set. These parameters rarely need to be adjusted again. If a new parameter value is to be stored, it is necessary to go through the whole list, and confirm at the end.

Action is to be taken when the timer reaches 0.

The process parameters can be adjusted easily and as often as required, even during operation, to meet changes in the operating conditions, e.g. time between sludge discharges, oil temperature, alarm points.

NOTE

Regularly check the condition of the bowl. If there is no noticeable amount of hard sludge in the sludge space, the discharge interval may be increased by 30 minutes at a time. The total discharge interval must not exceed three times the factory set value in order to avoid an uneven build-up of sludge.
