Mounting Hole Detail
Monitor Housing
The FloTech model FT208 CheckMate Retain
/ Overfill Monitor Housing is typically
mounted in the trailer fitting storage box or any
flat surface within easy view of the bottom
loading connections. Leave the top cover on
the monitor housing and hold it in the position you
wish to mount it. Using a black marker, transfer the
pattern of the four mounting holes to the
mounting surface. BEFORE drilling, check
to make sure you will not drill through or damage any existing trailer wiring or piping. Drill the holes through
and mount the monitor using four 5/16 inch nuts and bolts.

Cable Installation Instructions
FloTech recommends you use FT404 jacketed 11-conductor cable for up to 8 compartment systems. This cable
is specially designed to be oil, UV, and abrasion resistant. It incorporates a noble tin-plated stranded copper
wire which resists corrosion. When installed properly, this cable will provide years of reliable service. See the
Proper Wire Connections section for more detailed directions about stripping and terminating the cables.
Monitor Housing
After the monitor housing is mounted, install FloTech FT402 cable glands in the openings where needed.
These are, as illustrated in Fig.3: Power, Top Sensors, Bottom Sensors (if equipped) and Socket. Route the
lengths of FloTech FT404 cable through the conduit openings. Cut the cables to length leaving approximately 8
inches of extra length inside the monitor housing.
Unused conduit openings in the sensor housings must have a ½ inch NPT pipe plug installed. Note that when
using the FloTech FT390 Dual Socket Assembly, you only need to install one cable gland for the socket wiring.

Wiring Instructions
Proper Wire Connections
Please read this section of the manual before attempting to wire the FloTech FT208 Monitor. This section
recommends some ‘guidelines’ for installing the system wiring that, when done properly, will insure a long,
trouble free service life for your equipment.
CABLE STRIPPING
FloTech recommends using FT404 eleven conductor cable to wire the Onboard Monitor System for up to 8
compartment systems. When stripping the rubber jacket from the cable, FloTech recommends using the
FT9023 or equivalent Cable Stripper. This stripper has an adjustable cutting blade depth setting. The depth
should be set to only cut through one-half to two-thirds of the outer jacket thickness. This will insure that the
insulation on the inner conductors is not nicked. Any nicks or cuts in the wire insulation can, over time,
degrade the quality of the wire and lead to intermittent or total failure.
CAUTION: Razor Knifes Will Cut The Inside Wire Insulation
SPLICE END CONNECTIONS
FloTech recommends using the FT9024 or equivalent Crimp Tool for securing the splice end connections.
Follow this process to secure each connection:
FloTech Programmable CheckMate Retain / Overfill Monitor
8 10466 REV N FT208 CheckMate
1. Follow the Cable Stripping instructions in the previous paragraph to expose the individual conductors of
the wire.
2. Strip the insulation back on each conductor approximately ½ inch. Take care not to cut off any strands
of wire. If too many strands were accidentally cut off, cut the wires flush with the insulation and strip
again.
3. Hold the two wires to be connected together by the insulation. Tightly twist the bare wires together.
This insures a good electrical connection.
4. Fill a FloTech 10112 splice end with Silicone RTV compound. Insert the twisted wires into the filled
splice. Check to see that the bare wires are fully inserted into the splice and RTV. Make certain that
NO bare wire is protruding from the splice.
5. Securely crimp the wires into the splice end.
6. Give the splice and the wires a ‘tug’ to make sure you have a good mechanical connection.
TERMINAL BLOCK CONNECTIONS
Follow this process to secure each connection:
1. Strip approximately 3/8 inch of insulation back from the end of the wires.
2. Tightly twist the strands of wire together.
3. Rotate the terminal block screws counter-clockwise a few turns to relieve pressure on the wire retainer.
4. Insert the bare wire end into the terminal block.
5. While holding the wire in place, rotate the terminal screw clockwise to tighten the wire retainer.
6. Once fully tightened, give the wire a slight ‘tug’ to insure that a proper connection has been made.
Monitor Wiring Connections
Before attaching wires to the FT208 CheckMate Monitor, please read the following:
CAUTION: Turn off or disconnect power to the trailer before wiring the monitor.
CAUTION: Only use the conduit opening marked “POWER INPUT” as shown in Fig.3 to wire power to the
monitor.
CAUTION: The FloTech FT208 CheckMate Monitor will not work on POSITIVE GROUND electrical
systems. Any attempt to wire the monitor to a positive ground system will damage the monitor and void the
warranty.
TB1 POWER Connections
Refer to Fig. 4. FloTech recommends routing the trailer power through a weatherproof inline fuse holder
(supplied) containing a 1/2 amp fast blow fuse to the monitor. Optionally, a switch can be added in series with
the fuse to the TB1 input. Connect the positive power supply wire to the TB1 terminal marked “12/24 VDC”.
This is the upper screw on TB1. Be careful that no stray wires are touching the metal barrier or ground
terminal. The Ground wire connects to the TB1 terminal marked GND.

SENSOR Connections
FloTech FT208 can be wired to
work with 2 wire FT151 sensors or
API 5 wire FT101 sensors. FloTech recommends wiring the sensors to the FT208 Monitor using FT404 11

conductor cable for up to 8 compartment systems. FloTech FT404 cable is color coded to ease installation and
troubleshooting. A color coded wiring schematic is provided in the back of this manual.
