7.2.4 Wiring of Manifold Pressure Sensor, MAP Signal, Load Signal
All cables must be fed through a cable gland at a suitable position of the CAN bus module. Use
suitable wire end ferrules for each wire that you place on a terminal.
Depending on the intended NO
X
monitoring mode (see Preferences on page 112), connect a mani-
fold pressure sensor 4–20 mA, a MAP signal 4–20 mA or a load signal 4–20 mA to input 3. You
can optionally connect another 4–20 mA signal to input 4, whose current value is displayed in
the EasyNO
ₓ
in the NO
X
Monitoring view. Note that the large cable gland at the long side of the
CAN bus module on the right is not available for input 4 if you connect a second CAN bus module
to this module (see section
Wiring of Power Supply and CAN Bus on page 65).
Connect the shields of the wires with the cable glands. Do not lay the shields inside the CAN bus
module. No bridges may be set between the measurement inputs.
Connect a manifold pressure sensor as shown in the following illustration. The cable cross-sec-
tion of the power supply cable from the manifold pressure sensor should be at least 0.5 mm
2
. For
smaller cable cross-sections, ensure that the cable is suitably protected.
Connect active signal sources 4–20 mA (MAP signal, load signal) as shown in the following illus-
tration. Use shielded wires for connecting active signals 4–20 mA.
