*) The function of the calorific value conversion in the ERZ2104 (calculation of energy
and energy totalizers in each totalizer unit) is an integrated function in the sense of
MID, but is not subject to MID. However, it was tested in the scope of the national
approval process for the ERZ2104.
The applicable approval (approval symbol) is specified on the type plate (
chapter
"2.5.5 Functions" – "Type plate"
). The corresponding seal diagrams can be found in
this manual or the approval (
chapter 1.5.3 Seal diagram
).
If a temperature transmitter for the ERZ2004 or ERZ2104 types approved in accord-
ance with MID, it must be secured as follows:
− The main plate is provided with a sealing label.
− Access to the calibration switch, which is set to "write protect" during normal oper-
ation, is secured by connecting the removable cover of the electronic housing with
sealing marks with the stationary parts of the housing.
1.5.3 Seal diagram for devices with MID approval
Normally, the ERZ2XXX-NG leaves the factory with the setting agreed upon with the
customer, which is protected from "significant" changes by seals for custody transfer
applications.
