Measurem. 7-11
Measurements 7-11 are 0…10V transmitter measurements. They can be
connected to pressure transmitters, CO2 content transmitters, humidity
transmitters, and air flow transmitters. These measurement channels can also be
used to receive On/Off information (see On/Off input selections p. 44)

Press the
button to select the transmitter output message.
Press
. The
character indicates what has been
selected. Press the and
button to set the amount of
pressure (Pa) at which the transmitter gives a maximum
message (10V or 20mA). Attention! Each pressure
transmitter measurement has its own settings.
Set which ppm content gives a 0V transmitter message and
which gives a 10V transmitter message. The range is 0
…2000 ppm.
Press the
button to select the transmitter output message.
Press
. The
character indicates what has been
selected. Press the and
button to set the volume of air flow
(m/s) at which the transmitter gives a maximum message (10V
or 20mA). The range is 0.0 …10.0 m/s.

TAKING INTO USE AND REMOVING FROM USE:
Free transmitter measurement channels (7-11) can also be
used for receiving On/Off information. (Taking On/Off
information into use, see p. 44)

Attention! If an mA-transmitter is used, approx. a 500
parallel
resistance must be connected to the measurement input.
