5. Operations
Cattron Patriot Wireless Control Systems are designed for control of industrial machinery. These rugged controls
are built to survive the wear and tear of life in factories, mills and foundries.
These systems comply with requirements for operation under Part 15 of the FCC Rules and Regulations. This
means that neither the operator nor the company need apply or register for a license to operate this equipment.
The basic system consists of a transmitter and a receiver. The transmitter sends commands to the receiver by
means of radio waves in the 900 MHz band. Receivers operate at 120 VAC 50/60 Hz power.
5.1 How the System Works
5.1.1 Frequency
Cattron Patriot equipment operates in the 902 to 928 Megahertz (MHz) frequency band. A wavelength at our
frequency is 12.9 inches.
Like light, 900 MHz radio signals pass through glass and plastics, and will reflect off of walls, buildings, and metal
structures. Unlike light, 900 MHz radio signals penetrate all plastics, including those that you cannot see through,
as well as thin-gauge steel, dry wood, dry concrete, plasterboard, fog and rain.
However, trees, earth, water, people, aluminum, copper and some window tints will not readily pass our signals.
5.1.2 Range and Antenna Coverage
Antennas convert radio signals into radio waves and convert radio waves back into radio signals. They can send
and receive in all directions or in a single direction, depending on their design.
An omnidirectional antenna is like a light bulb, and a directional antenna is like a flashlight. Metal objects reflect
radio waves, just as a mirror next to a light bulb will reflect light. Metal objects near an antenna alter the intended
pattern of an antenna by either shading or reflecting signals.
Our standard antennas are omnidirectional; they ‘see’ equally well in all directions. We have other antennas that
will ‘see’ further in one direction for special applications.
5.1.3 License-Free Channels
The 902 to 928 MHz spectrum is set aside by the FCC as an ISM Band (Industrial, Scientific and Medical), and
this spectrum accommodates many license-free users. We have the ability to change frequencies in this band,
and we have 81 different channels that we can assign to our transmitters and receivers. The actual frequency is
coded into the receiver and transmitter at the factory, but it can be changed to one of the other 80 channels in the
field.
Other devices in this band include wireless phones, computer data links and inventory equipment. As a condition
of using this band, our products must accept and handle interference from other users.
The 900 MHz band has worked well for most users, and not being burdened with licensing regulations is often
desirable. The FCC has allowed 50,000 microvolts per meter field strength on this band, which is 250 times
higher than other unlicensed frequencies below this band. This allows our systems to operate very reliably in the
presence of other signals.

5.1.4 Command Format
We use packet-mode, Frequency Modulation (FM) to carry commands in a packet form from our transmitter to our
receiver.
To reduce battery drain, our transmitter transmits for a hundredth of a second, which is long enough to send one
packet to our receiver at a repetition rate of either 16 times per second or four times per second.
The rate varies: 16 times per second for three times when sending a command and four times per second when
there is no change in commands and the transmitter is still on. Any time a lever or switch is activated, we send all
control settings three times at the 16-per-second rate and then return to the slower rate of four times per second.
Our receiver uses the slower rate for maintaining transmitter timing and provides for a maintained link where one
is used. The only exception to this is the ‘STOP’ switch, which transmits at 16 times per second as long as it is
depressed. In addition to lever and switch positions, each packet contains a unique address and CRC check sum
(described in the next section).
5.1.5 Safety
Safety and preventing loss of control are very important issues at Cattron. We use a unique identification (ID)
code for each user. There are provisions in the system for 65,535 individual codes.
Each transmission includes a CRC check sum, which is a polynomial created by factoring all of the previous bits
transmitted. Once the receiver receives a valid start command from the transmitter, the receiver tracks the time of
the transmitter and ignores all other transmissions that do not fall within the expected time frame of the
transmitter.
Maintained link systems must receive at least one valid transmission each second in order to allow the remote-
controlled equipment to function. The receiver provides a loss-of-signal control output that safely shuts down the
equipment if a loss of signal occurs.
The receiver will not allow restart of equipment under its control after a loss of signal until a valid system start
command is received from the transmitter. This prevents an unintended start-up from occurring if the transmitter
returns within range of the receiver and is still operating.
The transmitters also check the position of all controls upon start-up. The transmitter will not issue a start
command if any of the controls are pressed at the time the start command is invoked.
5.2 Transmitter Operation and Features
WARNING
Do not operate the system until you are familiar with radio-controlled operation. If you are not
familiar with radio-controlled operation, contact your supervisor before attempting to use the radio
control system.

IMPORTANT
To stop the system in an emergency, press and hold the OFF/STOP button. Pressing and holding
this button down stops all functions.
5.3 Operation
1. Press and release the ON/ALARM button. Verify that the status LED starts flashing at a low rate. If
equipped, the Alarm function should sound.
2. Press the required switches to operate the desired function. Note that more than one function can be
controlled at any time.
3. To stop sending any command, release the switch.
4. To switch the transmitter off, press the OFF/STOP button. (Note that the transmitter will switch itself off if
no commands are sent for a predetermined time if Auto Off is enabled).
5.4 Commands
5.4.1 Command Switches
The command switches are labeled according to their function.
•If opposing commands are attempted, that is, two commands that conflict with each other, in most cases
no function will result. In the case of ON/OFF functions, OFF will predominate
•If more than one speed command is sent for the same function, the lower speed will predominate
ON/ALARM
This button turns on the transmitter and puts the system in the active mode. It sends an ALARM command to the
receiver while the switch is depressed. The transmitter will remain active until the OFF/STOP button is pressed or
the transmitter switches itself off (see Auto Off).
OFF/STOP
While depressed, this button sends a STOP command to the receiver. The transmitter does not need to be
switched ‘ON’ to send this command. When this switch is released, the transmitter will be switched off.
A–B SWITCH
(25T15A only) A Selector switch is provided to control more than one similar function with the same controls (that
is, controlling hoist/trolley A, hoist/trolley B, or both A and B simultaneously). A single button will cycle between A,
B, BOTH, and OFF each time the button is pressed. LED indicators show the control status.
AUTO OFF
The transmitter will switch itself off if no commands have been sent for a predetermined time. This time is
normally set to 15 minutes but can be reset to 0–60 minutes (or disabled) using a RAC16A Series Programmer
(01 to 60 = minutes, 00 = disabled).
5.5 Status Indicators
5.5.1 Status LED
The status LED provides an indication of the transmitter operation. When the transmitter is operating normally, the
LED indicator will emit short flashes at a low rate when no commands are activated and at a higher rate when a

6. Installation
6.1 General
Check all of the components to confirm that they are the components you ordered for your system and that they
are in good condition. If any components are missing, or if any are not in good condition, contact Cattron at
www.cattron.com/contact .
WARNING
READ ALL INSTRUCTIONS. Failure to follow the SAFETY RULES can result in serious personal
injury. Before starting this installation, ensure that the crane power has been disconnected and
that all applicable safety precautions are followed.
Figure 5 in Section 6.6 shows a typical Patriot receiver. See this figure for mounting dimensions and antenna
connector location.
6.2 Locating the Equipment
6.2.1 Antenna Location
The antenna is one of the most important components of a radio receiving system. Proper placement of the
receiver antenna ensures reliable operation under the most severe conditions. A direct ‘line-of-sight’ path between
the transmitter and receiver antenna provides best performance (refer to Figure 3).
Figure 3: Transmitter/Receiver Communication
In most cases, the antenna may be mounted directly on the receiver cabinet. In determining the mounting
location, consider the following items:
•Mount the antenna vertically
•For optimum performance, give the antenna itself a minimum of 8 inches clearance in all directions,
excluding the wall or plate to which the receiver cabinet is mounted (refer to Figure 4)
•If the receiver cabinet location cannot provide this clearance and the antenna must be mounted at a
remote location, the Cattron Remote Antenna Mounting Kit should be used. See Receiver Spare Parts
List or contact Cattron at www.cattron.com/contact for more information

Figure 4: Antenna Clearance
6.2.2 Receiver Location
To ensure safe and reliable system operation, the following items must be considered when selecting a location
for mounting the receiver:
•Install the receiver in an environment where the ambient temperature during operation does not drop
below -20º F (-28º C) or rise above +160º F (+71º C)
•To ensure that the receiver enclosure is electrically at earth ground, connect the green wire in the
interface cable to earth ground
•Mount the receiver enclosure securely using appropriate locking-type hardware
6.3 Installation Wiring
WARNING
Before starting this installation, ensure that the crane power has been disconnected and that all
applicable safety precautions are followed.
CAUTION
Connection to equipment or contactors with higher voltage or current requirements requires
intermediate relays.
6.4 Output Snubbers
Snubbers are recommended for the suppression of noise generated from arcing relay contacts. When a contactor
opens, the contactor coil produces a large voltage potential, much like automotive ignition systems. When the
points open on automotive ignition systems, the coil sends a large voltage to the distributor. This voltage jumps
across the spark plug (called arcing). The result is a large amount of noise generated in the system.
A snubber is a device designed to reduce arcing (noise). To increase relay life, it is recommended that all
contactors have snubbers installed directly across the coils. If more snubbers are needed, see the Receiver
Spare Parts List or contact Cattron at www.cattron.com/contact .

6.5 Power/Control Wiring
See Figure 6 in Section 6.6 for Patriot receiver wiring diagrams.
Patriot receivers are prewired according to the wiring label on the face of the receiver. Limit the load current
applied to the output relay bank ‘common’ to 5 A maximum.
Use the following steps to install the wiring to the receiver.
1. Connect the ‘hot’ input wire for the bridge (X1A) to the black wire of the interface cable. This provides
power for the bridge and alarm functions as well as power for the receiver.
2. Connect the neutral (X2) wire for the bridge to the white wire of the interface cable. This provides power
return for the receiver.
3. Connect the ‘hot’ input wire for the trolley and hoist (X1B) to the black/white wire of the interface cable. If
only one power source (phase) is used, this will be the same as Step 1 above.
4. Connect the red wire to the coil of the main line (ML) contactor. This wire will provide a continuous
voltage to the ML Coil when the transmitter is active. If a pendant is also connected to the controls, we
recommend the addition of a transfer switch to select either pendant or radio control.
5. Connect the remainder of the wires to the control relays as required.
Note: The standard Patriot receiver can interface to either 3- or 4-wire hoist controls. When installing the
Patriot on standard 3-wire hoist controls, the two wires for hoist second speed (GRN/WHT and
RED/WHT) need to be joined and wired into the appropriate location for hoist second speed.
Review the steps above to ensure the accuracy of the wiring before applying power to the installation.
6.6 Installation Testing
Before putting the system into service, the following testing procedure must be performed:
1. Apply power to the receiver.
2. Verify that PWR indicator turns on. See Figure 5.
3. Turn on the transmitter.
4. Verify that the SIGNAL indicator flashes.
5. Verify that voltage is present at the receiver output to the Main Line Contactor (MLC).
6. Verify that no voltage is present at any of the relay output terminals that are used for your application.
7. Recheck the system wiring if voltage is present at any output terminal that is used.
