1 Introduction
1.1 About This Manual
This document will describe the recommended procedure for installing a FINCH II Display. A Titan Logix system
must be installed and operated in accordance with the details described in the Titan Logix manuals, application
notes and all other relevant publications.
- This Manual (TPM010) is specific to the FINCH II Installation and Operation.
- For complete information on the TD100, please refer the TD100 Product Manual, TPM 057.
- For complete information on the RCM, please refer to the RCM Product Manual, TPM 007.
1.2 Disclaimer
The information in this document is subject to change without notice. Titan Logix Corp. makes no
representations or warranties with respect to the contents hereof.
WARNING
Only qualified personnel familiar with the installation and operation of this equipment should
install, adjust operate, or service this equipment. Failure to observe these instructions and
applicable safety and electrical regulations could result in bodily injury or loss of life.
Only replace with sand filled fuses of same type and rating.
EXPLOSION HAZARD –Substitution of components may impair suitability for Class 1, Division 2.
EXPLOSION HAZARD –Do not connect or disconnect equipment or replace fuse unless power has
been switched off and / or the area is known to be non-hazardous.
EXPLOSION HAZARD –Batteries must only be changed in an area known to be non-hazardous.
To maintain a Class 1, Division 2 rating, each relay must only be supplied with
8-30VDC / 3.3A max transient protected power.
1.3 FINCH II
The FINCH II Display is weather-proof device for internal or external use.
It provides bright LED numeric display of volume information, alarms, and
system error codes from the TD80 and the TD100 transmitter. Various alarm
and error conditions are detected by the transmitter and display. These alarm
states control four internal relays for alarming, high level shutdown and low-
level prevention.
The FINCH II contains high power relays to directly control a bottom loading
solenoid valve or control of an onboard loading pump.
- FINCH II-W provides Rack control (RCM)support for 1 or 2 compartments.
- FINCH II-6W provides Rack control (RCM) support for up to 5 compartments.
2 Installation
2.1 Pre-Installation Requirements
1. When choosing a location to install the Titan Logix system, the following guidelines must be followed:
- Appropriate industry, national, provincial/state, and local codes.
- Fuses and components are appropriate for the area classification.
2. The tank is completely drained of liquid and vapour free.
3. No drilling or welding to the tank and frame without first consulting with the tank manufacturer.

The TD100 must be programmed before use. Programming may be done at the factory when
purchased, programmed by the customer prior to installation or after installation on the vehicle when
necessary.
The FINCH II display may need to be programmed. Alarms are assigned to internal relay actions for
flexible alarm annunciation and high-level shutdown. The factory settings are appropriate for most
applications. Programming may be done by prior to installation or after installation on the vehicle when
necessary.
2. Install the TD100 as indicated in the TD100 Installation and Operation manual. (TPM 057)
3. Mount the FINCH II display in a suitable location (preferably in a weatherproof enclosure)

6. Electrical Installation
- The TD100 transmitter is provided with a 50’/ 75’ cable kit. It is recommended to use the kit with
included sealing fitting for connection to the FINCH II display.
- All electrical grounding is to the vehicle or trailer electrical ground connection and not to the chassis.
- Wire splices should be made inside a weatherproof enclosure to prevent premature failure due to
corrosion.
•Probe and Transmitter location
•Probes (Dual Rod & Coaxial)
•FINCH II Display location.

Note 2-1: Electrical Installation
1. Vehicle manufacturers usually have specific locations for electrical power access. These
locations are fuse protected to limit short-circuit current. Refer to the vehicle
documentation or contact the manufacturer for the recommended locations prior to
the electrical installation.
2. For trailers, connect the TD100 system power and ground to the nose box electrical
connector. This will be a fused electrical power source from the truck. For trucks,
connect TD100 system power to a switched and fused accessory power connection
from the battery. A switched electrical power source is required to reduce battery drain
while not in operation.
3. When making connections to the vehicle electrical ground, ensure that the wiring is
terminated at a battery ground terminal. Some metal components are electrically
insulated from the battery ground or bolted with painted surfaces causing a poor
connection.
4. Wire splices should be made inside a weatherproof enclosure to prevent premature
failure due to corrosion.
5. Secure all wires and cabling with clips or cable ties.
6. Tighten all compression fittings.
7. Follow all federal, state/provincial, and local safety standards and industry
recommended practices for the vehicle.
2.5 Basic Single or Dual Compartment Installation (FINCH II-W)
Wiring steps for a basic single or dual TD100 transmitter and FINCH II-W installation.
Refer to Figure 2-4 through Figure 2-7 for the wiring diagrams and schematics. Observe the recommended cable
routing in Figure 2-5 and Figure 2-7 to minimize external wiring connections. All wiring interconnections should be
made inside a weatherproof enclosure.
Note 2-2: Electrical Installation
1. Terminals on the FINCH are identified by the name of the connector group: terminal
name (terminal number), for example PWR IN: GND IN (1) describes the power
ground terminal at the far-right hand side of the FINCH terminals.
2. The Power Switch, Remote Alarm Acknowledge push button and Horn are optional
accessories.

Observe the recommended cable routing in Figure 2-9 to minimize external wiring connections. All wiring
interconnections should be made inside a weatherproof enclosure.
The wiring steps described below and in Figure 2-8 and Figure 2-9 are the recommended TD100 Transmitter and
FINCH II Display installation for hazardous locations. The most common control devices for high level shutdown
are:
1. A normally closed (NC) bottom loading valve
OR
2. A normally open (NO) hydraulic motor bypass valve
Note 2-3 Electrical Installation for High Level Shutdown
•Terminals on the FINCH II are identified by the name of the connector group: terminal
name (terminal number), for example PWR IN: GND IN (1) describes the power ground
terminal at the far-right hand side of the FINCH terminals. See Figure 2-2
•The Horn, Remote Alarm Acknowledge, Power Switch, Red and Green lights are optional
accessories.
•The DISPLAY EN signal must be connected to a switch controlled by the Power Take-Off
(PTO), brake air pressure or some other device to indicate product loading will take place.
The terminal may be permanently connected to GND if this feature in not used.
•Power may be controlled by an optional brake air pressure switch when Anti-Lock Brake
(ABS) power is used for the TD100 system.

Electrical Wiring Instructions
1
Optional power control switch on ABS power (J560 socket, pin 7) using a brake air pressure switch.
Follow Step 1a and 1b for the optional power control or Step 1c for a dedicated TD100 system power.
a. ABS power wire from the nose box socket or junction box to the pressure
switch common (COM) terminal.
b. The pressure switch normally closed (NC) terminal to the FINCH PWR IN: PWR IN (1).
OR
c. Locate a switched and fuse protected source of electrical power. Wire from the nose box to FINCH
PWR IN: PWR IN (1). See Note 2-1.
2
Ground wire from the nose box socket or junction box to FINCH PWR IN: GND IN (2)
3
Optional PTO or brake air pressure switch. Follow the instructions in Steps 3a and 3b for the switch
installation. Follow Step 3c if the switch is not installed.
a. Wire the FINCH REMOTE IN: DISPLAY EN (3) to the normally open (NO) contact of the switch.
b. Wire the FINCH REMOTE IN: GND (2) to the common (COM) terminal of the switch.
