close. The operation of this relay can be changed to be opposite of
that described above (failsafe) through the software configuration.
mA Output
A milliamp output current loop is available at TB1-7(+) & 8(-) that provides a
current proportional to the highest temperature.
RS-232 Link
An RS-232 data link is provided for setting up the 118 ETM. TB1-9(RCV) is the
data going to the ETM. TB1-10(XMIT) is the data coming from the ETM. TB1-
11(GND) is the ground connection for the data link. Refer to the Setup Software
section of this manual for more detailed information.
NOTE:
Wires should be connected to the RS-232 terminals only during
parameter setup. No permanent field wires should be connected to these
terminals.
