The assignment of the connection terminals of the ERZ2000-NG is essentially speci-
fied by the compact configuration. However, there are reserves, because a different
definition of the terminal assignment is necessary depending on additionally installed
extension modules. The positions of the extension boards and assignments for the
plug strips are specified in the additional data sheet for the device. The unoccupied
slots can be optionally equipped with the following extension boards:
1. DSfG board for flow corrector and registration instance and DSfG
control station
2. Ex isolation board for volume (measurement and comparison), Vc, p and
T with 4..20mA or HART
3. HART board for 3 transmitters or as a double circuit board with up
to 6 transmitters
4. Frequency meas-
urement board 5..8
for density transmitters with a density conversion
The modules that are used are recognized automatically by the ERZ2000-NG. The
menu
EH Module assembly shows the modules recognized by the system and in-
serted. Therefore, the menu is provided as information for automatic recognition or
troubleshooting. This information is important for the assembly of device combina-
tions in the factory or for equipping modules at a later time.
