Manual setup of primary volume counter V

is not allowed at encoder input..
Installation and replacement of gasmeter
Actual counter of gasmeter is transferred into EVC after connection of encoder
and EVC possibly causing big difference at primary volume Vm. To prevent against
affection of base volume Vb (Vbs) it is necessary to keep following instruction:
1. In service SW 22 display device parameters, select subject „Encoder SCR“
and push button „Encoder exchange“. During encoder exchange will be
stopped processing of primary volume from gasmeter. (Further follow
instructions shown on PC display).
2. Connect physically encoder to EVC.
3. After connection of encoder finish installation/exchange with OK button.
During installation/exchange ( meant from point 1) no differences are added to
appropriate counters which are marked on display with exclamation mark. If point 3 is
not finished by one hour exchange procedure will be closed automatically at service
SW.
5.1.4 Binary inputs
These inputs monitor the input signals with the option of an evaluation of the
condition “connected” (i.e. log. 0) or “disconnected” (log. 1). The device allows the
evaluation of the binary inputs from the no-potential outputs (reed contact or open
collector – these signals are on DI1 and DI2 inputs connected to terminals LF+, LF-)
or from sensors of the type NAMUR (DI1 and DI2 inputs, terminals HF+, HF-) The
NAMUR sensors require an external supply voltage of the converter higher than 7 V
(e.g. from JBZ-02).
By setting the parameter, the user can choose the display of the instantaneous
values on the display, storing the changes of these inputs in the archive; display the
headline for condition log. 0 and log. 1, and active signal level.
