The pump displays whichever of four auto running screens is appropriate according to the previously selected auto mode -
The auto running screens display four pieces of information: the speed at which the pump rotates after receiving a low signal on Analogue 1 (4mA or 0V); the speed at which the pump rotates after receiving a high signal on Analogue 1 (20mA or 10V); the set speed (that is: the speed at which the pump is current- ly rotating according to the analogue speed signal and the analogue scaling sig- nal if scaling is set); and the flowrate in the units selected (see 18.8 Flow units). The scaling percentage is also displayed if it is set.
If manual scaling is enabled using the Setup menu (see 18 Setup), the scaling percentage can be adjusted between 0% and 100% using the UP and DOWN keys.
The pump responds to remote digital inputs. If the run / stop input stops the pump, the bottom line of the auto running screen shows “Remote stop”. When it starts the pump again, this will disappear and the pump returns to normal running mode.
If the pump is stopped because a leak is detected, the screen displays “LEAK DETECTED. Check and reset, then press Stop”. See 25.1 Error codes.
The remote status outputs operate fully.
How to get out of auto operation
Pressing the AUTO/MAN key displays three options: Analogue, Manual and Network. Use the UP and DOWN keys to choose and press ENTER to con- firm.
Selecting Manual returns the pump to manual operation. Using this method of changing from AUTO/MAN, the pump retains the set speed from its pre- vious operation in manual mode in a stopped condition. See 14 Manual operation.
Selecting Network puts the pump into network (RS485) mode. See 24 Network control and operation.
Selecting Analogue returns the pump to analogue mode. It responds to the analogue signal as soon as this is done and shows the “AUTO” icon.
Alternatively, make the remote auto / manual input go low (0V). The pump returns to manual operation and retains the set speed and run status from its previous operation in analogue mode.
