Totalizer pulse output

Each time the flow meter reaches a consistent flow, it can generate a totalizer pulse. The totalizer
pulse can be transmitted to a remote counter via OCT (Open Collector Transistor) or a relay.
Therefore, it is necessary to configure the OCT and relay accordingly (see windows M33 and
M34). For example, if it is necessary to transmit the positive totalizer pulse via a relay and each
pulse represents a flow of 10 m
•
Open M41 and select the totalizer flow unit "m
•
go to M41-MULT and select the scaling factor "e. x10";
•
in M34-Option, select "g. POS Total".
Attention!
Make sure to select a suitable totalizer pulse. If the totalizer pulse is too high, the
output cycle will be too long; if the totalizer pulse is too low, the relay will operate
too fast. You can shorten the life of the relay and skip some pulses. It is
recommended that the totalizer transmits within the range of 1 ... 3 pulses per
second.
