A.2 Special case of revision with orifice flow meter
If the coordinate ED01 Revision mode is switched from "Operation" to "Revision"
in menu E Mode , submenu ED Access , it is possible to follow the measurement
values of the pressure cells during the check of the individual delta-p cells in
GZ Orifice function key . The corresponding current inputs of the cells are dis-
played in menu AP diff.pressure .
Therefore, during the check of a delta-p cell, the entire range can be monitored
from 0 to max. value.
There are 2 revision modes:
"Revision"
Standard function, activated by menu.
To be used for tests with series connection.
Totalizers run and are identified in the archive.
Output pulses are stopped
"Revision via contact" Standard function, activated by external contact.
To be used for tests with series connection.
Totalizers run and are identified in the archive.
Output pulses are stopped.
The contact input to be used can be selected as ac-
cess to the parameter in
ED12 Source revision ctc.
Coordinates
ED13 total. in revision , ED14 Temp. at revision and ED15 Pres-
sure at revision define the behavior of the ERZ2000-NG during the revision:
If the totalizers stop during the revision, "At rest" must be selected in
ED13 . If
pressure or temperature should remain at the last valid temperature during a revi-
sion, "retained value" must be selected in
ED14 and ED15 .
