Thank you and congratulations on purchasing the most professional vehicle detection system
available! It has been manufactured to give years of trouble-free service. However, if it should need
servicing, please consult the dealer/installer who installed your system.
Read these instructions completely. Each system should be bench-tested by the dealer/installer
before installation. The installer should become acquainted with the CF-2C control unit and sensor
probe in the shop; make all adjustments and settings; and study all system functions. If there are
any questions or problems that need to be discussed, contact the technical staff by calling our 800
number.
SPECIAL NOTE:
Look for information gleaned from the field contained under the heading “SPECIAL
NOTE” throughout this manual (see “Field Troubleshooting” on page 11 for a complete list of them).

Attached to the relay on the circuit board is a sticker with a set of
numbers and letters. This series of numbers and letters reveals the
specific unit, its year of manufacture, its issue number, and ends with
the serial number (see illustration).
When calling Cartell for technical help, please have these numbers handy so your call may be
handled in a timely manner.

Install the control unit in a dry, weatherproof building away from heavy electrical motors, radio
transmitters, main power service, or any equipment that may introduce electrical or R. F. noise.
Install control unit in a sealed box when used in a corrosive atmosphere such as an animal barn or
chemical plant.
Install in a sealed, weather-proof box when installed outside. The weatherproof box must have a
thermostatically controlled light bulb or heater to maintain temperatures above freezing. Drastic
changes in temperature cause condensation on the board and will make the unit malfunction.

On the CF-2C circuit board is a floodlight relay (normally open, dry contact) rated 15 amps at 115
VAC. Two 12 gauge, black wires connected to this relay exit out the back of the CF-2C case. This
floodlight relay can be used to operate three types of systems:
1. The relay can be used to operate up to 1800 watts directly (see Figures 1A, 1B, and 1C and
“Installing Control Unit” next page).
2. The relay can be used to operate the coil of an auxiliary relay or contactor to power banks of
lights (see “Installing Control Unit” below).
3. The relay can be used to activate low voltage lighting up to 15 amps maximum.

See Figure 1, top of next page. Install a single-gang electrical box in the wall behind the control unit
so that the black wires from the unit go directly into the electrical box.
With the power to the floodlight switching system off, run a 14-gauge, two-wire Romex cable from
the new single-gang electrical box to the existing floodlight switching system as shown in Figure 1A.
Connect the Romex cable across the switch of a single-switch system as shown in Figure 1B.
