0 Safety regulations

1. Please read through the Operating Instructions carefully before placing the FC (Flow Controller) into operation. Please perform all steps precisely as instructed.

2. Please follow all the instructions and indications.

3. Always disconnect the electrical power supply before opening the housing.

4. The FC is protected under safety regulation IP44. This means that it is conditionally splashwater-proof; particles may get in the housing

5. Please ensure that the mains voltage used corresponds to the value specified on the name plate.

6. Interrupt the electrical power supply immediately and call a technician in the following cases:

Ø Water or other fluids have penetrated the FC. Ø The FC does not function correctly despite precisely following all instructions

in these Operating Instructions. On no account may you attempt to modify the unit yourself or remedy the problem by randomly pressing the entry keys.

Ø If the FC has been dropped and the housing is damaged.

1 Introduction

The FC has been developed for measuring and monitoring the consumption of fluids. For this purpose, it is connected to the DIGMESA measuring devices fitted in the pipes. The liquid-crystal display informs the consumer of the quantity which has flowed through.

The FC with limit value is used, amongst other things, to monitor water filters or water softeners etc.

For example:

Ø Activated-charcoal filter for cleaning and detoxifying the water. Ø Ion exchanger and filter cartridges for conditioning the water on coffee ma-

chines.

Ø Monitoring the ion exchangers on washing machines. Ø etc...

1. Remove the MSD with 4 contacts by pushing out the plug ➀ with the fixing screw ➂ on the rear side of the MSD.

2. Remove the plastic screw ➅, washer ➄ and rubber seal ➃. Pull the individual

parts in the order in which you removed them over the cable, followed, finally,

by the housing ➁. Expose the 3 wires of the cable (3-core, max 0.25 mm

section) by cutting back the cable sheath over a length of approx. 15 mm. Then strip the insulation from the individual wires over a length of approx. 5 mm.

3. Now screw the three wires into the corresponding terminals: Positive (Digmesa colour code: brown) into terminal 1. Negative (Digmesa colour code: green) into terminal 2. Connect the signal of the flowmeter (Digmesa colour code: white) to the terminal with the earthing symbol. Note down the colours of the cables so that you will be able to then correctly connect the measuring devise (colours of the wires may vary from country to country). Please note that terminal 3 is required only in conjunction with the FC programmer.

1. You will require an MSD with 3 contacts (Item No. 941-0002/3) in order to connect the measuring device to the FC. This MSD may need to be ordered additionally, depending on the particular measuring device.

2. Connect the MSD to the measuring device as specified in Point 2.1 (Page 4), Point 1 to Point 3.

3. Now plug the rubber seal ➆ and plug with 3 contacts onto the measuring

device, earthing symbol plug to (signal symbo measuring device). Guide the

housing ➁ over the plug. You yourself can determine in what direction the cable is pointing, dependent on local conditions. Now tighten with the fixing screw ➂.

4. Now guide the rubber seal ➃, washer ➄ and plastic screw ➅ over the cable into the housing ➁ and tighten them so that the cable is held firmly and tightly.

section) by cutting back the cable sheath over a length of approx. 15 mm. Then strip the insulation from the individual wires over a length of approx. 5 mm.

3. Now neatly twist the wires, insert them into the individual terminals and firmly tighten them. Insert phase (brown in Switzerland) into terminal 1, negative (blue in Switzerland) into terminal 2. The terminal with the earthing symbol is not used.

3 Commissioning

3.1.1 FC without limit

0.00 and Litres are displayed as soon as the FC is connected to the electrical power supply.

3.1.2 FC with limit

The programmed limit value in litres and PROG are displayed for approx. 4 seconds as soon as the FC is connected to the electrical power supply. The FC is then in Working mode, and 0.00 and Litres are shown on the display.

4 Working mode

The FC displays the number of litres which have flowed through the flowmeter. This device has an automatic range-selection facility: from 0 to 999.99 litres with two places after the decimal point. If the displayed value exceeds 999.99 litres, the FC changes the display mode and displays only one place after the decimal point up to 9999.9. Above this value, only litres are displayed (up to maximum 99999 litres). After this, it starts again at zero with two places after the decimal point.

4.1 Function of the LEDs

4.1.1 Without limit

1. The green LED lights for as long as the electrical power supply is connected.

4.1.2 With limit

The limit value is monitored by the indication of the two LEDs. There are the following four indications:

1. The green LED lights for as long as the electrical power supply is connected.

2. If the number of litres exceeds 90 % of the programmed limit value, the green LED starts to blink.

3. As soon as the limit value is reached, the green LED goes out and the red LED starts to blink.

4. As soon as the limit value exceeds 10%, the red LED lights steadily.

4.2 Reset to zero

If you wish to set the counter to zero, button on the underside of the housing using the tip of a ball-point pen.

Press the Reset button adequately long (approx. 4 seconds) until the display is cleared. The zero-reset function will only have been performed when the display is cleared. As soon as you release the button, value 0.00 and LITRES are shown on the display.

6 Programming pulse count/litre without limit

The pulse count/litre (calibration factor) can be programmed only with an FC programmer, available as an option, Item No. 925-0200. Proceed as follows in order to change these values:

1. Undo the fixing screw ➂ (Fig. 1) of the MSD

measuring device is connected to the FC and carefully pull the MSD off. The FC remains electrically live.

2. Connect the MSD of the FC programmer to the the MSD points towards the right. The (already set) pulse count per litre is now shown on the display: 4 digits, with the digit at the far right blinking. This pulse count must correspond to that of the connected measuring device. You can find this information on the relevant data sheet or on the Internet at www.digmesa.com. If the pulse value is incorrect, it can be changed as follows.

3. The value of the blinking digit can be change by pressing key
