Pre-installation Checklist
CAUTION
Accurately and thoroughly document the Control Module port connections and dispense areas. If the Software
Map does not exactly match the way the cables are connected, the system will not operate properly . Errors that
could occur include: inability to turn on a fluid at a given dispense area; the wrong fluid or dispense point is acti -
vated; or a fluid dispense point is properly activated, but the wrong meter is monitored so the dispense job will not
shut of f properly .
This process is not difficult, but it is detailed and precise. Follow all steps and document them according to this
manual to ensure a successful installation.
Follow these steps before beginning to install the Horizon system.
n
Pre-installation Steps Reference
1. Locate the Floor Plan, System Map (diagram of component locations), and all
other documentation used to specify the system prior to ordering it.
If this information cannot be located, recreate it from the packing slip that
came with the system.
Packing slip and
Appendix, pages
51–69
2. V erify that all the parts on the Floor Plan match the parts shipped to you. Floor Plan, purchase
order , and packing
slip
3. V erify that all Horizon system components are marked in their proper loca -
tions on the Floor Plan. Floor Plan
4. Assign a name and number to all the control modules in the system. Record
the control module numbers on the Floor Plan.
D The Master Control Module (which the Administrative Keypad and printer
or computer connect to) is always assigned number 1.
D Additional Slave Control Modules are numbered in sequence as 2, 3, etc.
D The control modules do not have to be in numerical order along the
network cable.
Floor Plan
5. Assign a name and number to each dispense area. Record the names and
numbers on the Floor Plan.
D The dispense area usually consists of banks of hose reels, but may also
consist of oil bars or individual hoses.
D The names should make sense to the shop personnel who will use the
system. For example: Fast Lube, Service Bay 3, etc .

Hardware Installation
CAUTION
It is important to follow the floor plan or note any
deviations as the software addresses will be setup
according to what the floor plan shows. If addresses
and physical connections do not match, the system
will not operate properly .
1. Flush the System
Flush the fluid and air lines thoroughly to remove any
particles that could clog the meters.
2. Install Solenoids and Meters
WARNING
A Pressure Relief Kit is required in the
Horizon system to reduce the risk of
serious injury , caused by splashing fluid
in the eyes or on the skin resulting from component
rupture from over-pressurization. See Fig. 18,
page 67. See page 50 to order the kit.
Install the fluid system with the meters and solenoids in
their designated locations. Install pressure relief kits,
check valves, ball valves, fluid filters and other acces -
sories that are shown in the floor plan. Refer to Appen -
dix, pages 67 to 69.
3. Set Control Module Addresses and
Label the Boxes
Each control module is numbered. The Master Control
Module is always number 1. The Standard Control
Modules can have an address number from 2 to 40.
Set the control module addresses with the DIP
switches as shown in the chart on page 9. Refer to
the Detail drawing of the DIP switches in Fig. 1. See
page 43 for the location of the DIP switches in the
control module.
Label the control module boxes with their designated
number.
NOTE:

The Slave Control Modules are shipped with their
address set to 0.
 The addresses are binary numbers.
 It is imperative that each control module has a
unique address, set by the DIP switches. Each
packet of information sent through the network
contains the unique address of the control module
the information is intended for . If the DIP switches
are not set to the correct address, the control
module will not receive its information. If two control
modules have the same address, both of them will
receive the information and try to act on it, resulting
in system errors and incorrectly dispensed jobs.
 DIP switch 7 is used to tell the control module
whether a basic keypad or enhanced or administra -
tive keypad is connected to it. The OFF position
indicates a basic keypad is connected. The ON
position indicates an enhanced or administrative
keypad is connected.
 DIP switch 8 should be in the ON position for
normal system operation. The OFF position turns
on all six solenoid drivers in the control module.
This option can be used when there is a system
failure and fluids need to be dispensed. The moni -
toring and controlling of dispensed fluids is disabled
when the switch is in the OFF position.

WARNING
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
T o reduce the risk of fire, explosion, and
electric shock:
D All wiring must be done by a qualified electri -
cian.
D
Ground the Horizon system by connecting the
electrical power cable to a true earth ground.
Wire the control module(s) into the facility’ s electrical
system. It is recommended that the system be wired to
a separate circuit breaker . This will help prevent acci -
dental shutdown of the system and make it easier to
power of f the system when necessary . The system is
designed to remain powered-up continuously during
normal operation.
T o ease system maintenance, install a switch for
turning of f the power at each control module. Locate
the switches near each control module, but out of
reach from the floor to prevent accidental shutof f of
power to the control module.

Cable Routing and Connection
9. Connect the Control Modules to the
CAN (Controller Area Network)
WARNING
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
T o reduce the risk of fire, explosion, and
electric shock all wiring must be done by
a qualified electrician.
The cables are connected at each control module by
stripping the wires and connecting the wires as shown
in Fig. 10. Refer to Fig. 9 for the placement of the
control module connectors.
Each control module ships with a terminating resistor
on the connector for the CAN network. When the cable
is connected to the control module, the resistor must
be removed from the control modules located in the
middle of the network chain, leaving only the resistors
at each end of the network. The end resistors are
necessary for the control modules to be able to com -
municate properly with each other across the network.
 Connect the control module(s) in the middle of the
network chain as shown in Fig. 10, with the termi -
nating resistor removed.
 Connect the control modules at the end of the
network chain as shown in Fig. 10, with the termi -
nating resistor in place.
