P
P
P
[
P
] key must be briefly pressed. Once the highest digit has been set and confirmed with [
P
],
the lowest digit will begin to flash again.
Example:
The 4 is flashing; this is the lowest value digit and, by
flashing, it is asking for a figure to be entered. In our
example, the value is to be changed from 75.64 to
75.00. You can change the value by changing the figure
from 4 to 0 using the [
S
] or [
T
] key. To move to the
next digit, the [
P
] key must be briefly pressed. The 6 begins flashing. Change the value
from 6 to 0 using the [
S
] or [
T
] key. The 5 and the 7 need no change.
Saving parameters
All parameters must be acknowledged by the user by pressing the [
P
] key for one second.
The changed parameters are then taken over as the current operating parameters and
saved in the EEPROM. This is confirmed by horizontal bars lighting up in the display.
Example:
Save the parameters by pressing [
P
] for one
second.
All the newly entered data are confirmed by the unit.
If no confirmation is received, the relevant parameters have not been saved.
Example:
You receive confirmation from the unit that the
changes have been saved through the appearance
of horizontal bars in the middle segments.

Change to the operating mode
If no key is pressed in programming mode for approx. 7 seconds, the unit automatically
returns to operating mode.

Measuring input
The
IAKV
-2VR4C
is equipped with a measuring input for standard signals that
enables standardised signals (e.g. 4 … 20 mA) from all kinds of different measuring
transmitters on the market to be measured directly.
6.2.1.
Factory calibration
For this, various sensor values for 0 … 10 V, 0 … 5 V, 0 … 20 mA and 4 … 20 mA are
stored in the unit and can be called up via the parameter PN0. They are called
factory
calibrations
because the data were established during production and are saved
