6.1 Installation and function check
Installation check Monitor all connections making sure they are tight. In order to guarantee fault-free
operation, the terminal screws must be screwed tightly onto the connection cables.
Function check Measuring the analogue 4-20 mA output signal or following failure signals:
6.2 Commissioning
Commissioning Once the power supply has been connected the head transmitter is operational.
6.2.1 Quick Setup
Using the Quick Setup the operator is led through all the most important unit functions
that must be set up for standard measurement operation of the unit.
Using the HART
®
hand module a quick set-up of the black highlighted fields of the
HART
®
function matrix (s. fig. 6-2) is possible. Using the Commuwin II operating matrix
(s. fig. 6-3) a quick set-up is possible with the following fields:
• Type of sensor (V2H0)
• Unit meas. value (V2H2)
• Value for 4 mA (V2H4)
• Value for 20 mA (V2H5)
• Connection (V2H6).

Hint!
Selection of all head transmitter functions using the HART
®
hand module is done with
various menu levels with the help of the E+H function matrix (s. fig. 6-2). All head
transmitter functions are described in 6.2.3 "Description of unit functions".
What needs to be done:
1. Switch on hand module:
– Measurement unit is not yet connected. The HART
®
main menu appears. This
menu level appears for all HART
®
programming independent of the type of
instrumentation. Information to offline programming can be found in the
“Communicator DXR 275” operating manual.
– Measuring unit is connected. The menu level “Online” appears. In this “Online”
menu level the actual measured data such as measured value (PV) and output
current (AO) are continuously displayed. Entry into the TMT 182 operating matrix
is done using the line “Matrix Parameter”. This matrix systematically contains all
HART
®
accessible functions.
