Manual Input Procedure
The PM 5191 can be controlled either via the keyboard or via the IEEE/IEC bus. The keyboard is inhib-
ited when controlling via the bus and the REMOTE LED lights. .
In
LOCAL
mode, the maximum
number of digits that can be entered is identical with the number
legal input or values are shown by flashing of key LEDs and display. The PM 5191 does not accept
illegal inputs so that no damage can be caused by such wrong operations.
The parameters can be entered in any sequence. Previously entered values that remain unchanged do not
need to be entered again. (See chapter 3.5.4.).
