3.5.4 Connecting IQ sensors
Materials required  1 x SACIQ connection cable (see chapter 10 A
CCESSORIES AND
OPTIONS )
 1 x cable gland with seal
The module end of the connection cable already has the sheath
removed in the factory and all the wires are fitted with wire end sleeves.
Tools  Phillips screw driver
 Small screw driver.
Differentiating
IQ sensors of the same
type in the system
For the simpler correlation of measured value and measurement
location, the system provides the option of giving each IQ sensor a
user-defined name (see section 5.5.1). This name appears in the
measured value display.
When the IQ sensor is delivered, the name is identical with the serial
number. Therefore, after the initial commissioning, IQ sensors of the
same type can only be differentiated by the serial number that appears
on the measured value display. In order to prevent confusing the
IQ sensors when assigning the name, you can proceed according to
one of the two methods:
 Note the serial number of the IQ sensor at the respective
measurement location before installation. Then, install all
IQ sensors. After the commissioning, open the list of sensors on the
controller. Then assign a suitable sensor name using the sensor
type and the noted serial number.
 Disconnect the IQ sensors of the same type from the connection
cables before commissioning the system. Then, put the system into
operation. After the commissioning, connect the IQ sensors
individually to the SACIQ connection cable. To do so, proceed step-
by-step sensor for sensor. After each newly connected IQ sensor,
select the Edit list of sensors menu on the terminal and assign a
suitable sensor name to the sensor.
Note
The list of sensors and the assignment of sensor names is described in
section 5.5.1 on page 5-12.
Connecting the SACIQ
cable to the MIQ module
The connection of the SACIQ cable to the terminal strip of an
MIQ module is described in section 3.5.3 (see C
ONNECTING THE
CABLES , Seite 22).
Caution
The SACIQ sensor connection cable may only be connected to the
SENSORNET connections. No wire of the cable may be connected
with an external electrical potential. Otherwise, malfunctions
could occur.
