1.4.1 Fitting the terminating resistor

Terminating
resistor
CP-DN8 9806NH
If the CPV valve terminal to be connected is at the end
of the field bus, a terminating resistor (120 Ohm, 0.25
Watt) must be fitted.
If you use a T-adapter, we recommend that the termi-
nating resistor be fitted on the unused output of the T-
adapter.
If you do not use a T-adapter, the terminating resistor
must be fitted in the field bus socket. To do this clamp
the wires of the resistor together with those of the field
bus cable between the cores Data + (pin 4) and Data -
(pin 5) of the bus cable socket.
PLEASE NOTE
In order to guarantee reliable contact, we recommend
that the wires of the resistor be clamped together with
those of the bus cable in common end sleeves.
