Parameterization
Toggle key
(P key)
NOTE
8-8
As the PMU only has a four-digit seven-segment display, the 3
descriptive elements of a parameter
♦ Parameter number,
♦ Parameter index (if the parameter is indexed) and
♦ Parameter value
cannot be displayed at the same time. For this reason, you have to
switch between the individual descriptive elements by depressing the
toggle key. After the desired level has been selected, adjustment can
be made using the raise key or the lower key.
With the toggle key, you can change
over:
•
from the parameter number to the
parameter index
•
from the parameter index to the
parameter value
•
from the parameter value to the
parameter number
If the parameter is not indexed, you
can jump directly from the parameter
number to the parameter value.
If you change the value of a parameter, this change generally becomes
effective immediately. It is only in the case of acknowledgement
parameters (marked in the parameter list by an asterisk ' * ') that the
change does not become effective until you change over from the
parameter value to the parameter number.
Parameter changes made using the PMU are always safely stored in
the EEPROM (protected in case of power failure) once the toggle key
has been depressed.
