Introduction
This manual provides general installation information for LOFA’s CP1000. This manual’s target audience
is professional installers for Engine Distributors and OEMs of engine-driven machines. The engine
manufacturer specific application information should be followed for any detailed or specific
requirements. LOFA sales and technical support are available to discuss specialized requirements or
custom applications.
Mechanical Mounting
The CP1000 control panel is adaptable to a wide variety of applications. The included engine
harness connector facilitates quick installation. The following is list of installation guidelines:
1. Panel mount shall be
a. Easily accessible by operator
b. Away from moving equipment
c. Stable during equipment operation and transportation
2. Vibration isolation mounts shall
a. be properly installed,
b. have normal movement, and
c. panel must not hit adjacent structure during operation
WARNING!
Correct any problem before proceeding to the next step! Continued testing may damage
the panel, harness or engine!
1. Turning key switch on initiates self-test, Check all connections and battery polarity on
failure
2. Test to verify over current protection, Identify and correct wiring fault on failure
3. Verify fuel run/stop solenoid or ECM energizes
4. Fuel solenoid should be powered for 10 to 30 seconds when key turned on
a. ECM should send CANbus data as soon as self-test completes
b. Verify engine cranks when key is turned to start Check all connections on failure
5. If engine does not start, Check fuel/bleed fuel lines
6. Verify gauges and indicators with engine running
a. See user manual for details
7. Test safety shutdowns
a. See user manual for details
8. Run engine for extended time to identify temperature or connection problems

AluFlex™ Panels
AluFlex panel enclosures are constructed from extruded aluminum and powder-coated for
durability. The faceplate is aluminum or powder-coated galvanized steel and the backplate is
powder-coated galvanized steel. The enclosure is splash proof and includes condensation drain
holes in the bottom. AluFlex panel isolation mounts are preinstalled to a heavy-duty mounting
bracket with mounting holes to accommodate various installations. Isolator mounts should not
be twisted when installed. Doing so will lead to premature failure.
Mounting Templates
The following two (2) pages have the one-to-one hole template for the CP1000 mounting bracket.

Typical Wiring
The following describes the typical engine interface wiring.
Power and Ground
The panel’s Power and Ground must connect directly to the battery posts and must not share its power
and ground wiring with any other devices, especially any high current loads. The Power line should have
over-current protection in the form of current limiting devices, fuses, circuit breakers or fusible links
protect harness wiring in the event of fault conditions.
ECU Power Out
The CP1000 can directly power the engine ECU

Starter Power Out
The Starter Power Out is intended to power the starter relay, which is required. When power is removed
from the relay coil, the collapsing magnetic field generates a negative voltage surge. Negative voltage
surges can damage components. The CP1000 has protection against these negative surges. However, it
is still required to have a protection/suppression diode as close to the relay as possible. LOFA
recommends the use of relays that have this protection/suppression diode built-in. The
protection/suppression diode must have sufficient voltage ratings to survive and sufficiently suppress
these negative voltage surges. LOFA recommends a 1N4001 diode. LOFA sales a spike suppressing diode
kit (630-4007-77).
Resistive Senders
The Resistive Sender connections send System Voltage out to the sender to obtain the current value. It
is required that the Sender Return connection be connected to a ground point (engine chassis as an
example) as close to the sender as possible in order to get an accurate measurement. If more than one
sender is used, each sender should have a sender return connected to a ground point near that
particular sender. All sender returns should then be connected together near the panel and the
combined returns connected to the panel’s sender return input.
CANBus Termination
CANBus requires two 120 Ω termination resistors each at the extreme ends of the wiring harness.
Typically, the engine ECU provides the termination resistor on its end (see engine documentation to
verify). The CP1000 has a termination resistor that can be turned off and on as needed. The CP1000’s
default configuration has this termination resistor turned on.
