2. Feed the connection cable of the travel sensor into the M12 cable gland of the positioner and connect to the terminal board
as shown in the wiring diagram (see “Electrical connection with cable gland“, page24).
3. Feed the connection cable for the electrical supply and signal transmission into the M16 cable gland(s) of the positioner and
connect to the terminal board as shown in the wiring diagram (see “Electrical connection“, page23).
4. Connect the 24 V DC supply voltage and potential earth.
5. Connect analogue input 0-20 mA, 4-20 mA or 0-10 V to the appropriate terminals for the specification of set values.
6. Then tighten all cable glands.
ð The cables must be held firmly on all sides.
NOTICE
Malfunctions caused by differences in potential
▶ In order to compensate for differences in potential due to plant-specific malfunctions, a jumper can be placed between ter-
minals GND and Iw-.
12.2 Version with connector (optional)
NOTICE
▶ GEMÜ 4231 and 4232 travel sensors with the M12 plug connection can be used for this version.
1. Connect the connection cable with the appropriate travel sensor connector to the X3 M12 built-in socket on the side of the
positioner.
2. Connect the connection cable with the appropriate connector for electrical supply and signal transmission to the X1 and X2
M12 plugs of the positioner as shown in the layout (see “Electrical connection“, page23).
3. Connect the 24 V DC supply voltage and potential earth.
4. Connect analogue input 0-20 mA, 4-20 mA or 0-10 V* as appropriate for the specification of set values.
