1.1 How to use this component operating manual
Structure of the
IQ SENSOR NET
operating manual
Fig. 1-1 Structure of the IQ SENSOR NET operating manual.
The IQ SENSOR NET operating manual has a modular structure like the
IQ SENSOR NET itself. It consists of a system operating manual and the
operating manuals of all the components used.
Please file this component operating manual in the ring binder of the
system operating manual.
1.2 Features of the MIQ/T2020 terminal
The MIQ/T2020 terminal is an extension component for the
IQ SENSOR NET system. It can be docked on – and removed again from
– any free lid front of an MIQ module as a mobile control unit. The
docking is performed by a simple manual action without the need for
any tools.

Information that describes the behavior of the terminal after the docking
maneuver can be stored in each MIQ module. This information inclu-
des:
lThe name of the respective measurement location
lA selection of measured values that should be displayed at this
measurement location.
This function (local identity function) can be used, e.g. for sensors to
quickly find the calibration on site. The information is transmitted by the
two upper contacts on the back of the terminal.

nal safety The failure-free function and operational safety of the MIQ/T2020 is only guaranteed if the generally applicable safety measures and the
special safety instructions in this operating manual are followed during
its use.
The failure-free function and operational safety of the MIQ/T2020 is
only guaranteed under the environmental conditions that are specified
in chapter 7 TECHNICAL DATA.
Safe operation If safe operation is no longer possible, the MIQ/T2020 must be taken
out of operation and secured against inadvertent operation.
Safe operation is no longer possible if the MIQ/T2020:
lhas been damaged in transport
lhas been stored under adverse conditions for a lengthy period of
time
lis visibly damaged
lno longer operates as described in this manual.
If you are in any doubt, contact the supplier of your MIQ/T2020.

Note
Follow the installation instructions in the INSTALLATION chapter of the
system operating manual.
Up to three terminal components can be docked on an IQ SENSOR NET
system.
3.2.1 Docking and removing a terminal
The mobile MIQ/T2020 terminal is docked on the lid of any free
MIQ module. The terminal can be docked while the system is running
without the measurement being interrupted.
Docking the terminal
Fig. 3-1 Preparing the MIQ module for docking
1Pull the cover off the contacts (pos. 1 in Fig. 3-1) on the lid of
the MIQ module.

Note
For the temporary docking of a mobile terminal, do not remove the
whole contact cover. Leave it hanging on the side of the MIQ module.
After removing the terminal, replace the cover again to protect the
contacts.
Fig. 3-2 Docking the terminal
Removing the terminal To remove the terminal, press the locking lever and pull the terminal
forwards.
2Place the terminal on the module lid. To do so, insert the flap
on the back of the terminal into the slot on the door hinge of the
module. Then, pull back the interlocking lever (pos. 2 in Fig. 3-
2), place the terminal completely on the module and release
the interlocking lever.

3.2.2 Docking the terminal on the IQ SENSOR NET S184 system
A free module is required to dock a mobile MIQ/T2020 terminal. With
the IQ SENSOR NET S184 system, there are the following options to
gain a free module:
lExpanding the system by an MIQ module, e.g. MIQ/IF232
lRemoving the MIQ/CR3 module from the preassembled MIQ/S184
module stack and mounting it separately (distributed mounting).
Materials required l1 x SNCIQ or SNCIQ/UG connecting cable
lWire end sleeves for 0.75 mm2wire cross-section with matching
crimping tool
l1 x cable gland with seal (scope of delivery of MIQ module).
Tools lCable stripping knife
lWire stripper
lPhillips screw driver
lSmall screw driver.
Note
General instructions concerning the system expansion and mounting
are given in the system operating manual.
Removing the MIQ/CR3
from the MIQ/S184
module stack and
mounting it separately
1In the case of process control via
lthe MIQ/CR3 module
lthe MIQ/IF232 module (with data server),
bring all instruments used for process control into a secure
condition (e.g. activate manual control).
2 Disassemble the MIQ/CR3 module from the IQ SENSOR NET
S184 system.
3Disassemble the contact carriers on the back of the MIQ/CR3
module.
4 Mount the MIQ/CR3 separately (distributed mounting).
5Mount the MIQ/C184 module on the MIQ/PS module.

3.2.3 Initialization
When the system is running, the terminal automatically starts to
operate as soon as contact is established to the IQ SENSOR NET. In the
first phase, the background illumination of the display switches on and
the terminal is initialized. This process can take several seconds. The
following display appears (Fig. 3-3):
Fig. 3-3 Display during the initialization process
The terminal then switches to the measured value display.

4.1 Introduction
The MIQ/T2020 terminal is a control unit for the IQ SENSOR NET.
The terminal can be used to:
lDisplay measured values
lStart calibration
lPerform system and terminal settings
lDisplay messages.
Note
To guarantee data security within the IQ SENSOR NET, access to the
following functions is only possible from one terminal at the same time:
lOpening the Settings/Einstellungen menu
lStarting the calibration
lAssigning sensors or output modules as substitutes.
If one of these functions is active at another terminal, a note appears
on the display.
