H ERROR INDICATIONS

FOREWORD During the normal meter operation, unusual conditions may occur and

compromise its proper functioning. K900 electronics was designed to

recognize one of these conditions and inform the operator by means of a

display message. In these cases, an error indication will be displayed in-

stead of the total; the partial indication continues to increase while blinking.

The unusual working conditions recognized by the meter are the following:

Exceeding of the

maximum meter

ﬂow rate

he flow rate of the fluid dispensed may exceed the max. allowed flow rate,

thus damaging the meter gears. Should this condition occur, “HI FLO” will

be displayed:

From one of the mea-

surement chambers

no pulses are found

The meter consists of two adjacent measurement chambers, held

together by a manifold. The fluid, by flowing through the appliance, rotates

the gears in the two chambers which, during their rotation, transfer, “vol-

ume units” of fluid. The exact measurement of the dispensed fluid is done

by counting the number of rotations made by the gears in both chambers

and consequently counting the transferred “volume units”. Each chamber

is associated with a transmission channel of “volume units”.

- chamber 1 channel 1 (CH1 WHITE wire)

- chamber 2 channel 2 (CH2 YELLOW wire).

Should the gears of one of the two chambers block or the counting elec-

tronics of one of the two chambers break down, counting of the dispensed

quantity would not be correct.

To make the user aware of this fault, “E1” is displayed:

“E1 CH1” means that “channel 1 has stopped”: in chamber 1 no fluid is pass-

ing because the gears are blocked or the electronics is faulty;

“E1 CH2” means that “channel 2 has stopped”: in chamber 2 no fluid is

passing because the gears are blocked or the electronics is faulty.

In one measuring

chamber more ﬂuid

is passing than in the

other

If the gears of one chamber are slightly obstructed, they slow down the

transfer of fluid which, in the other chamber, will flow more quickly. In this

conditions it will be displayed:

“E2 CH1”: fluid in chamber 1 is slower than fluid in chamber 2 CHECK

GEARS OF CHAMBER 1.

“E2 CH2”: fluid in chamber 2 is slower than fluid in chamber 1 CHECK

GEARS OF CHAMBER 2.
