OPERATION VIA BRAIN TERMINAL
Products with optional code / BR (BRAIN communication function) come equipped
with a BRAIN communication function which allows them to communicate with
dedicated BRAIN terminals (BT) or CENTUM systems. In the BRAIN series communi-
cations system, a
±
2 mA, 2.4 kHz modulated signal is superimposed onto the 4 to 20
mA DC analog signal for data transmission. Since the modulated wave is an AC signal
superimposed on the analog signal will cause no error in the DC component of the
analog signal. Thus, monitoring can be performed via communications while the
ADMAG AE is online.
A BRAIN terminal can be connected to the terminals shown in Figure 7.1 on products
that are not provided with / BR (BRAIN communication function).
7.1 Operation Via the BT200
This section describes the operation procedures using a BRAIN terminal. For details on
the functions of the ADMAG AE, see Chapter 6, "Function and Data Settings." And
also, see the "BT200 Instruction Manual" (IM 1C0A11-01E) for more detailed informa-
tion.
7.1.1
BT200 Connections
(1) Connecting BT200 to Converter
-CoCA-(Communication) is displayed
during communication.
Use these
terminals when
the product does
not have a display.
Figure 7.1 Connection of BRAIN terminal to Converter
For products not provided with / BR (BRAIN communication function), the terminals
for BRAIN communication are provided on the circuit board. Please connect BT200 to
the terminals on the circuit board directly.
(2) Connecting the BT200 to a 4 to 20 mA DC Transfer Line
The communication signal of the ADMAG AE with / BR is superimposed onto the 4 to
20 mA DC analog signal to be transferred.
