4 Operation
The measuring instrument displays the current measurement value. The display blinks if values fall
below, or exceed the measuring range. Zeros which precede the decimal point are not displayed.
Depending upon instrument configuration, one or another of the parameters is removed. The follow-
ing are a few of the important instrument configurations:
• Limit value relays: 2 or 4 relays, each with min-min, max-max or min-max contacts
• Minimum value panel meter
• Maximum value Panel meter
• Min. max. value storage
• Alarm storage
4.1 Limit Values (Option)
The instrument can be used as a CONTACTING INSTRUMENT , if limit value relays are used (option).
For programming of parameters see table on page 12.
P
Read-out of selected limit values and minimum and maximum measurement values
Depending on the model, either 2 or 4 limit values can be digitally selected. The limit values LOL1,
LOL2 and HIL1, and HIL2 function either as min-max, min-min or max-max contacts, depending
upon the selected function.
Depending upon the selected function, the relays work either according to the principle of bias cur-
rent or load current. If no special particulars are included concerning the type of contacts, and if
these are not indicated on the serial plate, the measuring instrument has been laid out at the factory
with min-max contacts for load current. Instrument settings cannot be changed when it is installed.
Corresponding instructions are described in programming for cod2 (see table on page 13).
