3 DME Functions Functional description The electronically controlled variable-speed motor of the DME pump provides optimum control of the stroke speed. As shown in the figure below, the duration of each suction stroke is constant while the duration of each discharge stroke varies according to the capacity set, resulting in optimum discharge flow in any operating situation.

3 DME Functions Menu The DME dosing pumps feature a user-friendly menu. To activate the menu, press the button . During initial start-up, all menu texts appear in the English language. You can set the menu to display other languages, see page 14. TM04 8484 0612 mA Fig.
3 DME Operating modes The pump ensures constant dosing according to the quantity set in l/h or ml/h by means of the and buttons. The pump automatically changes between the measuring units. Applies to DME-AR and DME-AP The pump ensures dosing according to an external analog signal. The dosed capacity is proportional to the input value in mA. Setting Input signal Dosed quantity as a percentage of the max.
3 DME Pulse-based batch control Applies to DME-AR and DME-AP The set quantity is dosed in batches at maximum capacity or the set capacity limitation. The time until the first dosing (NX) and the following sequences (IN) can be set in minutes, hours and days. The maximum time limit is 9 days, 23 hours and 59 minutes (9:23:59). The lowest acceptable value is one minute. IN must be higher than the time required to perform one batch. If IN is lower than the time required, the next batch will be ignored.
Maximum capacity limitation makes it possible to reduce the maximum capacity (MAX. CAP). It influences the functions in which the pump normally operates at maximum capacity. Under normal operating conditions, the pump cannot operate at a capacity higher than the one stated in the display. When pushing the maximum capacity button, the pump operates at 100 %. With the maximum capacity limitation function, a large pump can be set to operate as a much smaller pump.
3 DME Functions Languages Bus communication The display text can be displayed in one of the following languages chosen in the set-up menu: • English, German, French, Italian, Spanish, Portuguese, Dutch, Swedish, Finnish, Danish, Czech, Slovak, Polish, Russian. The DME-AP is available with a built-in module for bus communication with PROFIBUS DP systems. This module enables remote monitoring and setting via the fieldbus system. All DME features are available via bus communication.
3 Definitions Units Correct dosing stroke: A pulse from the dosing monitor corresponds to the internal stroke signal within acceptable time. Incorrect dosing stroke: There is no pulse from the dosing monitor corresponding to the internal stroke signal within the acceptable time (the pump is not pumping). It is possible to select metric units (litre/millilitre) and US units (gallons/millilitre).

8 DME Pumped liquids 8. Pumped liquids The resistance table below is intended as a general guide for material resistance (at room temperature), and does not replace testing of the chemicals and pump materials under specific working conditions. The data shown are based on information from various sources available, but many factors (purity, temperature, abrasive particles, etc.) may affect the chemical resistance of a given material.
