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...

2.1 Connection input plug FC-slot A
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.

plug ➀ so that the cable outlet is at the right. Now
tighten with the fixing screw ➂.
5. Guide 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.
