Electrical connections

Equipment variants
The assignment of the connection terminals of the ERZ2000-DI is essentially
specified by the compact configuration. However, there are reserves, because a
different definition of the terminal assignment is necessary depending on addition-
ally installed extension modules. The positions of the extension cards and assign-
ments 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
cards:
1. Ex isolation card
for volume (measurement and comparison), Vo, p and T
with 4..20mA or HART
2. HART card
for 3 transmitters
The modules that are used are recognized automatically by the ERZ2000-DI. The
menu
LB 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.
Figure 60: Menu LB
Module assembly
shows the equipment for the ERZ2000-DI that is in use. (This in-
cludes a COM 6 / COM 7 card for additional interfaces and a Hard card for digital
communication with pressure and temperature sensors.)
