Note
The serial COM1
interface of 07KT9x is
no longer available.
The serial diagnosis
interface DIAG has a
reduced range of
functions and is not
electrically isolated
from the supply
voltage L+/M.
Additional information
upon request.
Caution: Terminal
"Shield" is internally
connected to FE
(functional earth).
At the counting input,
an external resistor of
470 Ω / 1 W must
always be connected
upstream. For further
information on high-
speed counters,
please refer to the
AC500 documenta-
tion.
