Attix7_ver.1.0_140105 6/59 Nilfisk ALTO In this manual you will find the essentials you need to know when repairing wet and dry cleaners of the Attix 7 and 19 Gallon series. When carrying out repairs, make sure you have a suitable workbench or the like with the necessary power supply available. If you determine an error in operation, be sure to refer the customer to the user manual. Preface A fault in the equipment can have a number of causes. Chapter E Troubleshooting will help you here. Use the illustrated spare parts lists for your repairs. These show you the location of the individual parts and the sequence in which they are assembled. Read the technical information sheets. These will tell you about any technical modifications made after publication of this repair manual. Technical information sheets are a supplement to the spare parts list until a follow-on publication. Repair manuals and technical information sheets should be available at the site where repairs are carried out. Further repair manuals of the Attix series may be necessary for repairs to the equipment. It is not permitted to give them to third parties. Use original Nilfisk ALTO spare parts only!

If the turbine reaches a temperature of more than 85°C, motor speed is reduced. Electronic level control (Attix 751-61/-71, 19 Gallon AE) Alto no.: 302001712 (200–230 Vac/50–60 Hz) Alto no.: 302001711 (100–120 Vac/50–60 Hz) Several functions are integrated on this circuit board: - Main switch Pump Auto - 0 - Man - Speed control in manu al - Soft start - Level control - Turbine temperaturemonitoring Main switch: this allows selection of three modes. LED functions: Green LED (D2) on: operating voltage applied Pump: momentary contact for emptying the container. One-time operation causes the pump to run for 30 s. Green LED (D6) on: pump on Man: the turbine immediately starts. Auto: the turbine and pump are controlled as a function of the level. Speed control: the integrated speed control only works in Man mode. The control range is 90° to 130°. Advantages: - Optimal matching of suction capacity to the application - Prolonged turbine service life - Reduced noise emission - Power savings Green LED (D7) on: motor on Red LED (D3) flashes: microprocessor working Red LED (D5) on: level - turn off motor Yellow LED (D4) on: level - turn on pump Operating data: saved operating data can be read out on the Alto terminal (no. 301 000 383 for operating data retrieval). Continued on page 20 Attix7_ver.1.0_140105 19/59 Operation 14 Nilfisk ALTO Operation D Level control: Level control by means of a pressure sensor is implemented to optimize working with the equipment. The level in the container is metered in a rubber baffle pipe.The pressure sensor measures the difference in pressure between the container and the baffle pipe. Rising water level increases the pressure in the pipe. The pressure in the baffle pipe increases linearly with water level. Man mode: The electronic circuitry cuts out the turbine upwards of a defined pressure (water level), and remains in this status until the cleaner is turned off and the container emptied. The pump cannot be started in manual mode. The power of the turbine can be altered by speed control. Pump mode: The Pump switch setting is a momentary contact (automatic reset). One-time actuation causes the pump to work for 30 s. This function can be used to completely empty the container. At the same time this is a safeguard against the pump running when it is dry. Attix7_ver.1.0_140105 20/59 Operation Auto mode: Only the suction turbine runs when there is no water in the container. When the container fills with water, the pump is turned on. If more water flows into the container than the pump can convey out of the container, the level continues to rise. To prevent overfilling, the suction turbine is cut out at maximum level. As soon as the water level is significantly reduced by the pump, the suction motor is cut in again. Upon total emptying of the container, the pump is cut out with a time delay.
