Using Figure 3-7 as a reference, make relay
output connections as follows:
1) Strip wire insulation back approximately
0.250" (seven millimeters) to ensure the bare
wire will make good contact with the Insulated
Pin Lug terminals and will not be exposed
beyond the pin insulator.
2) Crimp Pin Lug terminals to the wire using
Panaduit CT 570 or equivalent.
3) Connect the wiring to the appropriate
relay output terminals.
Advantage Series (TBX5) Sensor Wiring
Instrument connections for the sensor wiring
are located next to the signal connections.
Sensor wiring should be run in shielded
conduit, or similar, for protection from
environmental influences. Do not allow the
wires to become wet. The wiring should not
lay on the ground or over any other equipment.
Ensure cables are not abraded, pinched or bent
during the installation process or during
normal operation.
The sensor cable has seven leads with pin
terminals that must be connected to the
terminal block in the rear cavity of the
TB84PH Advantage Series analyzer. The seven
leads are color coded and have the following
functions and connections:
Terminal Block Sensor Color Function
Location Code
TB2-1 Blue Sense
TB2-2 Yellow Guard
TB2-3 Black Reference
TB2-4 Green Solution Ground
TB2-5 Red RTD
TB2-6 White RTD
TB2-7 Hvy Grn Shield
TB2-8 N/A N/A
Remove the protective insulator from the Black
lead before installing it into the analyzer’s
terminal block. The insulator has been
provided to prevent shorting of the sensor
half-cell. Shorting of this conductor will
