Fitting the terminating resistor

CAUTION
If a terminating resistor is used, one of the
field bus plugs on the last valve terminal/val-
ve sensor terminal of a field bus line is not
assigned. Protection in accordance with pro-
tection class IP65 as per DIN 40050 is the-
refore no longer guaranteed. For this reason
a protective cap must be fitted to the non-
used field bus plug.
If the valve terminal/valve sensor terminal to be
connected is at the end of a field bus line, a ter-
minating resistor (120 Ω/0.25 W) must be fitted
into the socket of the incoming field bus line
(adaption). The non-assigned field bus plug must
then be covered with a protective cap.
