Vo
Original encoder counter reading or total volume on Input 1
Vo is the "origin counter" of the EK260, i.e. all the increments in the actual and
volume at base conditionss are derived from this.
In principle Vo cannot be changed by entry.
Vo is formed differently depending on the setting of Md.I1 (see above).
Md.I1 = 1 (Input I1 is the pulse input):
The pulses arriving on Input 1 (terminal "DE1") are converted into volumes with
the cp value cp.I1 and summed in Vo.
Md.I1 = 5 (Input I1 is the encoder input):
Vo is a copy of the gas meter reading (original cou nter). The EK260 interrogates
the counter reading from the encoder counter each measurement period. An
encoder should be connected just like a pulse transmitter on Input 1 (terminal
"DE1") of the EK260.
cp.I1
cp value Input 1
Pulse constant (parameter of the connected gas meter) for c onversion of the
pulses counted on Input 1 into the volume counters
Vo
and
V1
(see below); the
increase in volume is directly accepted into the total actual volume
VmT
(
→
3.2).
cp.I1
indicates how many pulses correspond to the volume of 1 m
3
.
If Input 1 is set as an encoder input (Md.I1
= 5, see below), cp.I1 has no
significance.
