    ELECTRICAL CONNECTIONS The pump must be connected to a power supply that is as indicate don the label on the side of the pump. Failure to respect the limits indicated may result in the pump being damaged. The MAXIMA range of pumps do not need to be earthed as they are made using components and technology that ensures that all electronic components are double insulated.

  • Page 22 3.1.1 Displaying the flow rate The flow rate can be displayed in three formats: Percentage (P), Frequency (F), ml/min. To switch from one format to another hold the Mode key down for three seconds, to move from one to another as per the block diagram below.

  • Page 24 3.1.5 Checking the level of the liquid to be dosed A level sensor can be used to check the level of the liquid to be dosed. Two operating modes are available: 14) Level alarm with pump cut-out: Level sensor connected to pins n° 8 and 9 (see CONNECTION LAYOUT).

  • Page 25: Operating Mode

    OPERATING MODE This paragraph describes the various operating modes available on the Maxima MPG. For changing from one mode to another, see the instructions in Paragraph 3.1. 3.2.1 Constant Mode In this mode the pump provides constant, continuous dosing at the flow rate set. During operation, to select CONSTANT mode, push the Prog key and hold it down.
  • Page 26 Displaying and Operation When operating in CONSTANT mode the display shows the flow rate set. This can be displayed in three ways (P, F, ml/min) as explained in Paragraph 3.1.1. icon is lit. When displayed as a percentage the icon is also lit. The STOP icon must be off while the pump is running.
  • Page 27 − Selecting Impulses (See Fig. 24) The number n displayed represents the number of external impulses required for the pump to dose one stroke. This value can be changed between 1 and 9999 using the ▲ or ▼ keys. For Example: If I have connected my pump to a CB1 series plunger impulse counter (1 imp/l) and have selected N=8, this means that every 8 impulses on the counter my pump will give one stroke, that is, for every 8 litres of water that pass the counter the pump will dose one stroke.
  • Page 28 Displaying and Operation On exiting programming the 100% default value will be displayed icon lit). The number displayed shows the percentage flow for each stroke dosed by the pump, for every n external signals received. icons are on and the STOP icon must be off while the pump is running.
  • Page 29 3.2.3 1:n proportional mode (Multiplication mode) In this mode the pump doses n strokes for every external impulse received, where n is a number that can be set by the operator. To select 1:n MULTIPLICATION mode, push the Prog key and hold it down. appears on the screen for a few ▲...
  • Page 30 − Memory Function (see Fig. 25) The software continually monitors incoming external signals. When the frequency of the impulses is high and the pump is not able to dose all the corresponding strokes, the outstanding impulses can be recorded, up to a maximum of 65,535, so as to dose these strokes as soon as possible.
  • Page 31 3.2.4 1:c Manual Mode In this Mode the pump does a settable number of strokes, C, on receiving an input impulse. This impulse may ▲ come from the outside (plunger impulse counter) or by pressing the key on the keyboard. To select 1:c MANUAL mode, push the Prog key and hold it down.
  • Page 32 − Memory Function (see Fig. 26) The software continually monitors incoming external signals. When the frequency of the impulses is high and the pump is not able to dose all the corresponding strokes, the outstanding impulses can be recorded, up to a maximum of 65,535, so as to dose these strokes as soon as possible (for example - there is a reduction in the flow of water through the counter).
  • Page 33 3.2.5 Direct Current Proportional Mode (0/4…20) In this mode the pump doses a proportional amount based on a 0/4—20 mA input signal, connected to PIN 11 (- pole) and PIN 13 (+ pole). the current at which the pump will dose can be set to its minimum (0 imp/min) and a current value that corresponds to the pump dosing the maximum flow rate, equal to a flow rate established in the factory.
  • Page 34 − Selecting the Upper Limit (see Fig. 27) Once this mode and the lower limit (L) have been selected, when the Prog key is pressed the lower limit is stored in memory and the letter H is displayed, followed by the upper limit (expressed in mA) for the current signal (default 20.0) at which the pump runs at the maximum frequency set.
  • Page 35 3.2.6 Inverse Current Proportional Mode (20…4/0) In this mode the pump doses a inverse amount based on a 0/4—20 mA input signal, connected to PIN 11 ( pole) and PIN 13 ( pole). The current at which the pump will dose can be set to its minimum (0 imp/min) and a current value that corresponds to the pump dosing the maximum flow rate, equal to a flow rate established in the factory.
  • Page 36 − Selecting the Lower Limit (see Fig. 28) Once this mode and the lower limit (L) have been selected, when the Prog key is pressed the lower limit is stored in memory and the letter H is displayed, followed by the lower limit (expressed in mA) for the current signal (default 4.0) at which the pump runs at the maximum frequency set.

  • Page 37: Calibration Procedure

    CALIBRATION PROCEDURE The flow rates on your pumps can be calibrated in situ in order to take the specific characteristics of the installation into account, such as the actual operating pressure, the product to be dosed, the stroke setting, etc. The cc stored in memory during calibration are used for displaying the ml/min.
  • Page 38 − Manual Mode (Man) (see Fig. 29) Having selected “Man” mode push the Cal key. No strokes will be made and cc value for the previous calibration or the default setting will be displayed. ▲ ▼ Use the keys to set the quantity of product expressed in cc. Values for the various pump models can be found in Table 1.
