Volume Conversion Device EK260
66 Elster GmbH
SC.O1 ... SC.O4 Source for Outputs 1...4
These values are only of significance if the mode Md.A... of the same output is set
to "1" (volume pulse output), "3" (time -synchronised output) or "8" (HF output).
If the error message "12" appears when attempt ing to make an entry, the address
cannot be used with the set mode (
Md.A... , see above).
For further details on entering a source: See Chap. 2.3.2.
Depending on Md.A... , the following settings for SC.A are practicable:
- for mode "1" or "5" (volume pulse output)
SC.A... Meaning
0002:300_0 Vb Volume at base conditions, undisturbed
0002:301_0 VbD Volume at base conditions, disturbance quantity
0002:302_0 VbT Volume at base conditions, total quantity (undis
disturbed)
0004:300_0 Vm Actual volume, undisturbed
0004:301_0 VmD Actual volume, disturbed
0004:302_0 VmT Volume at base conditions, total quantity (undis
disturbed)
The period duration and pulse duration can be set individually for each output
via the serial interface under the addresses "1:617" to "4:617" (p eriod duration)
or "1:618" to "4:618" (pulse duration) as a multiple of 125 ms. The period
duration must always be greater than the pulse duration.
- for mode "3" or "7" (time-synchronised output)
By programming SC.A... according to the following table, you can set at which
time points a time-synchronised pulse is output:
SC.A... Pulse is output
0001:143_0 At the beginning of each month at 0 hrs.
0002:143_0 At the beginning of each month at 6 hrs

0001:142_0 At the beginning of each day at 0 hrs.
0002:142_0 At the beginning of each day at 6 hrs

0001:403_0 At the beginning of each hour
0001:402_0 At the beginning of each minute

The pulse duration can be set individually for each output via the serial
interfaces under the addresses "1:618" to "4:618" as a mu ltiple of 125 ms.

The day boundary "06:00 hrs." can be set via the serial interfaces (address 2:141).

The output of a time-synchronous pulse each minute is only possible if the operating cycle
OCyc (

slightly.
