Using the BT200
IMPORTANT
• Analog output may change temporally in
connecting with BRAIN terminal due to
aninitialcurrentowedtoit.Toprevent
communication signal affecting the upper
system, it is recommended to install a low-
passlter(approximately0.1s).
• Communication signal is superimposed on
analog output signal. It is recommended
tosetalow-passlter(approximately
0.1s) to the receiver in order to reduce the
output effect from communication signal.
Beforeonline-communication,conrmthat
communication signal does not give effect on
the upper system.
• If the wiring system is faulty, ‘communication
error’ appears on the display.
• If the transmitter is faulty, ‘SELF CHECK
ERROR’ appears on the display.
