MINITRAC 31 • 4 … 20 mA/HART - four-wire

Information:
In this operating instructions manual, the instrument-specific param-
eters are described. Further general parameters are described in the
operating instructions manual "Display and adjustment module".
Caution:
During the first setup or after an instrument reset the instrument starts
with preset standard values. These value are not suitable for your ap-
plication and must be replaced by real values.
Carry out a setup in the sequence described in the following.
With this menu item you safeguard the sensor parameters against
unauthorized or unintentional modifications.
To avoid possible errors during parameterization in a non-safe user
environment, a verification procedure is used that makes it possible
to detect parameterization errors reliably. For this, safety-relevant
parameters must be verified before they are stored in the device. In
normal operating condition, the instrument is also locked against
parameter changes through unauthorized access.
For this reason, the instrument is shipped in locked conditon. The PIN
in the delivery status is "0000".
After a change, all safety-relevant parameters must be verified. For
this purpose, a character string comparison must be carried out. This
is used to check the character respresentation and the communica-
tion channels.
Confirm if the two character strings are identical. The verification texts
are provided in German and with all other menu languages in English.
In a second step, all modified safety-relevant parameters are listed.
Confirm the modified values.
If the described process of parameter adjustment was run through
completely and correctly, the instrument will be locked and hence
ready for operation.
