Once the error has been corrected,• press the "Start/Stop" button to restart the pump.– The pump returns to the state it was in beforethe error occurred.NoteIf the cable is broken, the dosingcontroller and pressure control/pressure display functions are notactive. When the "Menu/Info" button ispressed twice to display the chamberpressure, only "— — —" is displayed.9.10.6 Changing the number of permissible error strokesTo change the number of permissible error strokesduring the start-up operation and during normaldosing operation.NoteIf the sensor fault cannot be correctedimmediately and if the pump is tocontinue to run without a sensor,switch off the dosing controller(flow:OFF) and pressure controlfunction (P:OFF).MenuInfoService levelPermissible error strokesduring start-up operationNumber of error strokesuntil the error message istriggeredSt:60ERRORStopStartFE: 7ERRORUpDownUpDownUse the "Up" and "Down" buttons to set thenumber of permissible error strokes duringthe start-up operation in the range between1 and 99.Use the "Up" and "Down" buttons to set thenumber of error strokes until the errormessage is triggered during normal dosingoperation in the range between 3 and 99.StopStartTM03 6575 4506Fig. 63 Permissible error strokes1.
