￿MAX: while pressed, MAX operates the pump at the maximum allowed speed and in the direction shown on the display. When released, the pump returns to its previous status.

Note: Priming can be achieved by pressing the MAX key until fluid flows through the pump and reaches the point of discharge, and then releasing the MAX key.

￿AUTO/MAN: displays a screen offering three choices: manual control, ana- logue control or network (RS485) control. Use the UP and DOWN keys to make a choice. Press the ENTER key to confirm your decision. When started under analogue or network control, the pump runs at the speed set by any analogue or RS485 signal applied to the pump, and in the direction shown in the display.

￿STOP: has no effect if the pump is not running. If the pump is running, press- ing STOP stops the pump. The display will continue to show the previous speed and direction. The pump will return to this speed and direction when the START key is pressed again.

￿UP: increases the speed shown on the display in minimum steps of 0.1 rpm (unless the speed displayed is already the maximum allowed speed). If the pump is then started by pressing the START key, it will operate at the new speed. If the pump is running when UP in pressed, the change takes effect immediately.

Note: After a speed change, a screen showing the new rpm figure and the new flowrate is displayed for four seconds before returning the user to the pre- viously set manual mode main screen: rpm or flowrate.

￿DOWN: decreases the speed shown on the display in minimum steps of 0.1 rpm. If the pump is then started by pressing the START key, it operates at the new speed. The minimum speed possible is 0.1 rpm. If the pump is running when DOWN is pressed, the change takes effect immediately.

Note: After a speed change, a screen showing the new rpm figure and the new flowrate is displayed for four seconds before returning the user to the pre- viously set manual mode main screen: rpm or flowrate.

Note: You can reduce the pump speed from 0.1 rpm to 0 rpm by a further press on the DOWN key. The pump is still in the running state and the rotation symbol will continue to move. Press the UP key to return the pump to the min- imum speed.

￿DIRECTION: toggles the direction of rotation shown on the display. If the pump is then started by pressing the START key, it rotates in the new direc- tion. If the pump is running when DIRECTION is pressed, the change takes effect immediately.
