Deleting TOT
Quantity (
TOT1 and TOT2
) summation is done in the flow-measuring transmitters. In the MultiCONT it is possible to transmit the
TOT2
in preset units in the form of
relay impulses. In order to do this, the relay has to be switched to ‘
Impulse F’
mode. In the ‘
RP3’
parameter (belonging to the relay), specify the volume that will
trigger 1 impulse (the length of 1 impulse is about 200 ms). There is a ‘
PULSE’
and a ‘
TOTAL’
variable for each relay programmed to work in ‘Impulse F’ mode. The
‘
TOTAL’
variable of the relay goes after the ‘
TOT2’
variable of the transmitter. The volume difference between the 2 variables, given in ‘
RP3’
is put into the ‘
PULSE’
variable. The value in the ‘
PULSE’
variable is transmitted to the output of the relay. The ‘
TOTAL’
and ‘
PULSE’
relay variables get into the “non-volatile” memory even
in the event of a power failure, as a result of the (automatic)
saving
done every 6 minutes.The relay impulses that occur in the time elapse between the last save and
the return of power get counted again after the power supply is turned on. In order to avoid repeated counting, use a UPS.
Example
: Let the TOT2 value of the transmitter be 1000m
3
. Let the TOTAL value of the relay also be 1000m
3
. Let the PULSE value of the relay be 0.
At the same time, assume the RP3 parameter of the relay to be 10m
3
. In this case, no impulses appear at the relay output, because the TOT2 value of the transmitter
is the same as the TOTAL value of the relay. Based on the measurement of the transmitter the TOT2 value changes from 1000m
3
to 1050m
3
, the change being 50m
3
.
Also, based on the RP3 parameter of the relay (10m
3
unit volume), 5 is added to the value of the PULSE variable, with the change being 5*10=50m
3
. The relay then
counts 5 impulses. After this, the value of the relay’s PULSE becomes 0, while that of TOTAL becomes 1050m

Once in this menu, pressing ’OK’ will delete the values of the relay’s
’TOTAL’
and
’PULSE’
variables. This results in the total volume in the transmitter’s
’TOT2’
variable to be counted to the output of the relay based on the unit set in the
’RP3’
.
The delete operation is followed by the window below.
