Control Terminal Types - Trane TR200 Operating Instructions Manual

Installation
50/60 Hz earth (ground) loops
With very long control cables, earth loops (ground loops)
may occur. To eliminate earth (ground) loops, connect one
end of the screen-to-earth (ground) with a 100 nF
capacitor (keeping leads short).
Illustration 2.26
Avoid EMC noise on serial communication
This terminal is connected to earth (ground) via an internal
RC link. Use twisted-pair cables to reduce interference
between conductors. The recommended method is shown
below:

Connector 1 provides four programmable digital
input terminals, two additional digital terminals
programmable as either input or output, a 24 V
DC terminal supply voltage, and a common for
optional customer supplied 24 V DC voltage
Connector 2 terminals (+)68 and (-)69 are for an
RS-485 serial communications connection
Connector 3 provides two analog inputs, one
analog output, 10 V DC supply voltage, and
commons for the inputs and output
Connector 4 is a USB port available for use with
the Trane Drive Utility (TDU)
Also provided are two Form C relay outputs that
are in various locations depending upon the
frequency converter configuration and size
Some options available for ordering with the unit
may provide additional terminals. See the manual
provided with the equipment option
