  • Page 3: General And Safety Instructions

    1. General and Safety Instructions 1.1 General This operation manual contains basic instructions to be followed during installation, operation and main- tenance. It is therefore essential for the assembler and the responsible personnel/operator to read this operation manual before installation and start-up, and it must remain available at the place of installation at all times.
  • Page 4 German Association for Electrical, Electronic & Information Technologies Separate regulations must be observed if the MEMDOS E is operated in areas with a potentially explosive atmosphere. The operating company must determine the explosion hazard (area classification) and select the appropriate equipment.
  • Page 5 CAUTION! Particular care must be taken when repairing the MEMDOS E if used in areas with a potentially explosive atmosphere. Due to the risk of sparking, care must be taken to prevent metal parts or tools knocking against one another. When repairing, it is better to move the dosing pump out of the area with a potentially explosive atmosphere.
  • Page 6 WARNING! Lethal voltage! Adjustment work inside the ATE servomotor (optional for MEMDOS E) must be carried out carefully. Connec- tions and internal limit switches might be live. Additional limit switches might be live even when the auxiliary voltage is switched off (ATE servomotor). After installation work on the ATE servomotor, or before start-up, re-attach the cover.

  • Page 8: Function

    MEMDOS E The MEMDOS E is used where no control is required for constant dosing. In this case, the power supply is connected directly to the motor terminal box. To adapt the dosing capacity, either the stroke length can be adjusted manually from 0 to 100%, or the motor speed can be controlled by means of a separate frequency converter.

  • Page 15: Performance Curves

    6. Performance curves The performance curves refer to water at 20 °C (68 °F) and a suction lift of 0.5 m. The medium (density and viscosity) and temperature cause the delivery rate to change. Dosing pumps must therefore be gauged in litres for the application.

    (e.g. pressure loss for pipe dimensions i.e. nominal diameter and length). ATTENTION! For the MEMDOS E/DX 75 and 76, pipe dimension must be at least DN 10. The DN 6 pipe dimension is permissible only for short lines (up to 2 m) and low-viscosity media (<50 mPa s) .

  • Page 18: Installation Location

    ATTENTION! Note that the ATE servomotor can only be actuated when the main drive motor of the dosing pump is run- ning. This means that the ATE servomotor must be locked electrically. Otherwise, the adjusting eccentric will suffer excessive wear, or be destroyed. 7.2 Installation location The installation location of the dosing pump must be easily accessible by operating and service personnel.

    7.6 Level control If a level control is connected, the jack plug has to be covered by a plastic sleeve in order to maintain the protection class. The required sleeve is part of the level control (also in combination with a suction line). With the level control connected, the dosing pump stops if the chemical level in the supply tank is low, in order to prevent air bubbles from entering the suction line and the dosing head.

    8. Operation 8.1. Stroke length adjustment ATTENTION! The stroke length should not be adjusted while the dosing pump is stopped! Proceed as follows to adjust the stroke length: Turn the mounting screw on the adjusting knob counterclockwise (to the left) to loosen it. Set the stroke length to the required value according to the performance curves (section 6).

    Fill the dosing pump with the oil supplied. For oil grade and quantity, see paragraph 11.1. The MEMDOS E dosing pump is switched on by a control to be installed externally. The MEMDOS DX has its own control unit. Electrical connection and the control types are explained in section 8, MEMDOS DX operating controls.

    2 years, whichever comes first. The filling capacity is about 0.25 l for gears of sizes up to MEMDOS E/DX 156 and about 0.7 l for gears of sizes up to MEMDOS E/DX 380. The actual quantity of gear oil required can be determined by checking the min./max.
  • Page 31 The diaphragm can be replaced as follows: The delivery rate of the dosing pump is set to zero while the motor is running. This moves the diaphragm to the front end position. Switch off the pump. The head is removed using an appropriate tool. (see Fig. 1) Grasp the edge of the diaphragm and turn it to the left.
