5 OPERATIONS

Laird Command Pro Wireless Control Systems are designed to control industrial machinery. These rugged
controls are built to survive the wear and tear of life in factories, mills, and foundries.

These systems comply with operation requirements 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
through radio waves in the 900 MHz band. Receivers operate at 120 VAC 50/60 Hz power. Operation from
other power sources is also available.

5.1 How the System Works

5.1.1 Frequency

Laird Command Pro 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 reflect off of walls, buildings, and metal
structures. Unlike light, 900 MHz radio signals penetrate all plastics including those opaque in color, as well
as thin-gauge steel, dry wood, dry concrete, plasterboard, fog, and rain. However, the signal will not readily
pass through trees, earth, water, people, aluminium, copper, and some window tints.

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 accommodates many license-free users and is set aside by the FCC as an ISM
Band (Industrial, Scientific, and Medical). We have the ability to change frequencies in this band and have 81
different channels that we can assign to the transmitter and receiver. The actual frequency is coded into the
receiver and transmitter at the factory but may be changed to one of the other 80 channels in the field if
desired.

Other devices in this band include wireless phones, computer data links, and inventory equipment. As a
condition of using this band, products must accept and handle interference from other users.

The 900 MHz band works well for most users, and not being burdened with licensing regulations is 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 the band. This allows our systems to operate very reliably in the presence
of other signals.

10 142134

Command Pro Engineered Systems
User Manual

5.1.4 Command Format

This device uses packet-mode, Frequency Modulation (FM) to carry commands in packet form from our
transmitter to our receiver.

To reduce battery drain, the transmitter transmits for a hundredth of a second, which is long enough to send
one packet to our receiver at a repetition rate of 16 or 4 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 activates, we
send all control settings three times at the 16-per-second rate and then return to the slower rate of 4 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 loss of control prevention are very important issues at Laird. We use a unique identification (ID)
code for each user. There are provisions in our 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 equipment restart 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 does not issue a start
command if any of the controls are pressed at the time the start command begins. Exceptions for lights,
horn, bell, or other user functions that do not place machinery in motion can be mapped into our control
logic upon request.

FM systems also have a capture effect, where the strongest signal captures the receiver, which rejects the
weaker signal. The operator is seldom more than 300 feet from the controlled machine. Therefore, the
transmitter is the strongest signal present unless other equipment on this band is allowed to operate within
1000 feet of the location of the receiver.

5.1.6 Carrying Strap for ‘Belly Box’ Controllers

A Shoulder Carrying Strap (Part # 600057) is supplied with the 21T34A, 21T44A, 21T54A, and 21T74A ‘Belly
Box’-style controllers which greatly enhances operator comfort. Operators of these ‘Belly Box’-style

controllers are required to use this approved carrying strap with the controller attached at all times.

are not familiar with radio-controlled operation, contact your supervisor before
attempting to use the radio control system.

User Manual

5.2 Transmitter Operation and Features

IMPORTANT: To stop the system in an emergency, press and hold the OFF/STOP button.
Pressing and holding this button stops all functions.

5.3 Wireless Operation

1. If the transmitter the ‘belly box’ type, operators are required to use the supplied Shoulder Carrying

Strap with the controller attached at all times.

2. If the transmitter is equipped with pendant capability, verify that the pendant cable is not attached

before switching on the transmitter.

3. Press and release the ON/ALARM button. Verify that the Status LED starts flashing at a low rate. If

equipped, the Alarm function sounds.

4. Press the required switches to operate the desired function. Note that more than one function may

be controlled at any time.

5. To stop sending any command, release the switch.

6. To switch the transmitter off, press the OFF/STOP button. (Note that the transmitter switches itself

off if no commands send for a predetermined time and if Auto Off is enabled).

7. If equipped with a maintained OFF/STOP switch, the transmitter continues transmitting the

OFF/STOP signal for a preset time after the OFF/STOP switch is pressed to the maintained position.
Resetting the switch immediately switches the transmitter off.

5.4 Pendant Operation

1. Connect the pendant cable to the transmitter and receiver. If the transmitter was ON in the normal

mode, it will stop RF transmissions and send commands only through the pendant cable. The
transmitter will not resume RF transmissions until the pendant cable is removed and the
transmitter is momentarily switched off.

2. The remainder of the operation is the same as the wireless operation described above.

5.5 Commands

5.5.1 Command Switches

The command switches are labeled according to their function.

 If two commands that conflict with each other are attempted, in most cases no function results. In the

case of ON/OFF functions, OFF predominates.

 If more than one speed command is sent for the same function, the lower speed predominates.
 Maintained On or Off functions require separate commands for ON and OFF.

ON/ALARM: This button switches the transmitter on and puts the system in the active mode. It also sends
an ALARM command to the receiver while the switch is depressed. The transmitter remains active until the
OFF/STOP button is pressed or the transmitter switches itself off (see Auto Off).

12 142134

Command Pro Engineered Systems
User Manual

OFF/STOP: While depressed, this button sends a STOP command to the receiver. The transmitter does
not need to be actively ‘ON’ to send this command. When this switch is released, the transmitter switches
off.

AUTO OFF: The transmitter switches itself off if no commands are sent for a predetermined time.
Normally this time is set to 15 minutes, but it may be programmed from 0 to 60 minutes, or disabled using a
RAC16 Series Programmer (01 to 60 = minutes, 00 = disabled).

Levers (21T34A/44A/74A) / Joysticks (21T54A): When in the neutral (center) position, no commands send.
When a paddle moves from the neutral position, a command generates proportional to the amount of
movement (the further the lever is pushed, the faster the movement is commanded).

Push-to-Operate (PTO) Switch (Optional): The PTO or ‘Dead Man Switch’ is a safety device. The
transmitters are normally programmed so that the switch that activates this function must be depressed
before any motor or other critical function can operate (consult the Configuration Sheet if this switch has an
alternate use in your system).

First-Come First-Serve (FCFS) (Optional): The First-Come First-Serve option allows use of multiple
transmitters with one receiver, one at a time. The receiver scans a preset list of ID Codes. When a valid signal

is received, the receiver stops scanning and responds only to that transmitter’s signal. When the signal is no

longer being received (that is, the transmitter has been switched off or is out of range), the receiver again
scans until another valid signal is received.

Pitch-and-Catch (Optional): Pitch-and-Catch is similar to First-Come First-Serve but adds the safety
requirement that the operator in control must release or ‘pitch’ the control before another operator may
assume control. It also allows control transfer from one operator to another without pausing operation. Once
the transmitter has taken control of the receiver, the pitch button is the only way to release control of the
receiver so that other transmitters can take control. Once the receiver receives a valid pitch command, the
receiver then looks for the next programmed ID code. A Catch is made when the ID code from the next
transmitter is recognized. If a catch is not made within a pre-set time period, the receiver will revert to First­Come First-Serve until a valid ID code is recognized. Any switch can be programmed as the pitch button.

Note: If a transmitter malfunctions after the receiver has taken control, the only way to release the

receiver is to cycle power to the receiver.

A- B Switch (Optional): Selector switches can be provided to control more than one similar function with
the same controls (i.e. controlling trolley/hoist A, trolley/hoist B, or both A and B simultaneously). On the
handheld transmitters, a single pushbutton cycles between A, B, Both, and OFF each time the button is
pressed. LED indicators show the control status.

Key Switch (Optional): The key switch option can prevent the use of the transmitter by unauthorized
personnel. The key switch is electrically connected between the battery and the electronics so that all power
is removed when the switch is in the OFF position.

Note: Once power is applied, the red LED illuminates and the transmitter performs a self-test procedure

lasting approximately three seconds. The transmitter may be switched to ‘ON’. Under standard
operating conditions, the LED flashes green once when the transmitter switches to ‘ON’.

Magnet Control (Optional): An additional safety feature is built into systems that use a lifting magnet.
The two-button design uses one button labeled MAG LIFT (or LIFT) and one button labeled MAG DROP (or
DROP). Pressing the LIFT button energizes the magnet. Pressing LIFT and DROP at the same time de­energizes the magnet and drops the load.

A time-delay is built into the circuit, so the buttons must be held for nearly one second before the magnetic
controls activate. An additional switch may be provided for fanning or dribbling the load. Pressing the button
labeled FAN or MAG FAN while pressing MAG LIFT activates the fan drop function. Again, a time-delay is
built into the circuit, so these buttons must be held down for nearly one second before the magnetic controls
activate.

User Manual

Multiple Receivers Controlled by Multiple Transmitters Option: One transmitter can control a maximum
of six receivers with a rotary selector switch. A rotary switch is often used to select a particular hoist/trolley
A/both/B. It can also be used for crane select, i.e. East/West.

5.6 Status Indicators

5.6.1 Status LED

The status LED indicates the transmitter operation. When the transmitter is operating normally, the LED
indicator emits short flashes at a low rate when no commands activate, and at a higher rate when a
command activates. Some transmitters use a red LED only. Others use a multicolored LED that flashes GREEN
when no problems are present and changes to RED when problems are encountered. See Status Chart
below.

Table 1: Transmitter Status Chart

5.6.2 Function Select LEDs

Two LEDs are used on some transmitters to indicate which control functions are active (such as hoist trolley A
or hoist trolley B. These are commonly used with pilot relays). When both are illuminated, both controls are
active. When both LEDs go out, neither control is active.

User Manual

6 INSTALLATION

6.1 General

Check all 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 Laird.

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).

Controlled range systems require a special flat panel antenna. Refer to Installation Procedure - SAFE-T-

RANGE (21R22CR) for special considerations for the antenna used with that system.

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 eight (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 Laird Remote Antenna Mounting Kit should be used. See Receiver Spare Parts List
or call Laird for more information.

15 142134

Command Pro Engineered Systems
User Manual

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).

 All connections to the receiver enclosure must be watertight.
 Avoid mounting the receiver enclosure on a surface where excessive vibration or shock is present.
 For easy access to wiring and for service, provide sufficient room to open the enclosure door.
 To ensure that the receiver enclosure is electrically at earth ground, remove all paint from the

mounting-hole surfaces (refer to Figure 5).

Figure 5: Mounting-Hole Paint Removal

 Mount the receiver enclosure securely using appropriate locking-type hardware. This also assists in

properly grounding the receiver enclosure to the mounting surface.

CAUTION

Connection to equipment or contractors with higher voltage or current requirements requires an
intermediate relay.

!

WARNING

Before starting this installation, ensure that the crane power is disconnected and that all applicable
safety precautions are followed.

User Manual

6.3 Installation Wiring

Referring to the configuration sheet provided with the receiver (usually located within the receiver door),
dress the receiver output relay wiring and the control switch wiring along the inside wall of the enclosure.
This allows for easy troubleshooting and maintenance.

6.3.1 Receiver Power

Laird receivers are normally pre-wired for the most widely used control systems. Specific installations may
require rewiring the relay ‘commons’. When connecting the Laird receiver assembly to a power source that
has large amounts of interference (noise) generated by motors and/or contactors, use noise suppression
devices (snubbers) to prevent noise from triggering the receiver’s safety shut-down programming.

Never use the receiver case as a ground for other electrical equipment.

6.3.2 Relay Outputs

Limit the load current applied to the output relay bank ‘common’ to a maximum of 10 amps.

6.3.3 Output Snubbers

Snubbers are needed to suppress the 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 which jumps across
(arcing) the spark plug. The result is a large amount of noise generating in the system.

 A snubber is a device designed to reduce arcing (noise). Laird uses a resistor capacitor combination to

accomplish this function. To prevent noise entering the receiver, it is recommended that all contactors
have snubbers installed directly across the coils. If more snubbers are needed, See Receiver Spare

Parts List or call Laird’s Service Department at 800-328-5570.

6.4 Installation Procedure -21R14A Receiver

Refer to Figure 6 and Figure 7.

6.4.1 Power/Control Wiring

The transfer switch is wired so that the crane’s Main Line Contactor (MLC) is controlled by the radio MLC

relay when it is in the radio position and by the pendant controls when the switch is in the pendant position.
Refer to Figure 7 (21R14A) for typical input control wiring for overhead cranes. Transfer switch wiring is not
required unless there is a need for pendant operation. The switch can normally be wired without removing it
from the receiver cabinet. Any unused switch poles can be used for isolating additional functions.

Use the following steps to install the wiring to the receiver board and/or control transfer switch:

17 142134

Command Pro Engineered Systems
User Manual

1. Disconnect the ‘hot’ input wire X1 from the pendant and connect it to the (X1) terminal 11 of

connector TB1 on the receiver board (A).

2. If you also need 21R14A receiver installation pendant control, connect a wire from the top right lug

on the RADIO/PENDANT transfer switch to the X1 input for the pendant (B).

3. Install a wire (16 gauge) from the ‘X2’ terminal 12 (X2) of connector TB1 to the ‘neutral’ wire from

the Crane Control Power source (C).

4. Install a wire (16 gauge) from the ‘MLC’ terminal 1 (MLC) of connector TB1 to the main line contactor.

This wire will provide a continuous voltage to the ML Coil when the radio is on (D).

Review the steps above to ensure the accuracy of the wiring before applying power to the installation.
Perform 21R14A Installation Testing.

User Manual

6.5 Installation Procedure -21R22

Refer to Figure 8 and Figure 9.

6.5.1 Power/Control Wiring

The transfer switch is wired so that the crane’s Main Line Contactor (MLC) is controlled by the radio MLC and
OPR relays when it is in the radio position and by the pendant controls when the switch is in the pendant
position. Refer to Figure 9 for typical input control wiring for 21R22 receivers.

Transfer switch wiring is not required unless pendant operation is needed. The switch can normally be wired
without removing it from the receiver cabinet. Any unused switch poles can be used for additional isolation.

Use the following steps to install the wiring to the receiver board and/or control transfer switch.

1. Disconnect the ‘hot’ input wire X1 from the pendant and connect it to terminal 9 of connector TB4

on the receiver board (A).

2. If pendant control of the 21R22 receiver installation is also desired, connect a wire from terminal 7

of connector TB4 on the receiver board to the X1 input for the pendant (B).

3. Install a wire (16 gauge) from terminal 1 (X2) of connector TB4 to the ‘neutral’ wire from the Crane

Control Power source (C).

4. Install a wire (16 gauge) from terminal 4 (MLC) of connector TB4 to the main line contactor. This

wire will provide a continuous voltage to the ML Coil when the radio is on (D).

Review the steps above to ensure the accuracy of the wiring before applying power to the installation. Go to

21R14A Installation Testing and perform installation testing.

6.6 Installation Procedure – SAFE-T-RANGE (21R22CR)

Laird's ‘Safe-T-Range™’ is the latest advancement in wireless crane controls. ‘Safe-T-Range™’ keeps the
operator within a pre-determined distance from the crane, thus increasing safety in the workplace. Using an
advanced panel antenna design along with programmable logic, a ‘Safe-T-Range™’-equipped receiver draws
an electronic boundary around the crane and operator. The system then safely stops and inhibits selected
functions when the operator steps outside the boundary. This is done without shutting down the main
contactor line.

6.6.1 21R22CR Power/Control Wiring

Perform the procedure for installing the 21R22 Power/Control Wiring.

6.6.2 21R22CR Antenna Installation

The 21R22CR Receiver must be set up correctly using a special antenna and circuitry for the controlled range
function to operate properly. Use the following procedure as a supplement to the 21R22 Installation
Procedure.

The antenna for the 21R22CR has a specially shaped pattern that provides a sharp drop-off in signal strength
when the operator moves away from the antenna. The antenna has a shaped beam much like a broad flood
lamp, as shown in the following illustration.

25 142134

Command Pro Engineered Systems
User Manual

Figure 12: 21R22CR Antenna Pattern

For normal operation, place the antenna as close to the center of the bridge as practical so that the radio
control operation is symmetrical about the crane. Mount the antenna underneath the crane with a clear line
of sight to the area the crane operator uses. Position the antenna parallel to the ground and have the arrow
on its back side pointing toward either end of the bridge.

Use low loss cables to connect the antenna to the receiver if the cable run is in excess of 18 feet. Use Laird
P/N 600038-01 (9 ft), 600038-02 (18 ft), or 600048- (length in 25 ft. increments) for up to 100 feet of antenna
extension cable.

6.6.3 21R22CR Installation Testing

Perform the tests described in 21R22 Installation Testing on page 23. When these tests have been
successfully performed, proceed with the Control Range Alignment and Test.

6.6.4 21R22CR Control Range Alignment and Test

The Control Range circuit has two adjustments. The Range adjustment determines the maximum operating
distance from the receiving antenna at which the operator can control critical crane functions (refer to the
Control Range circuit board in Figure 13).

The Time Delay adjustment determines the length of time the signal must be below threshold before the
Control Range circuit activates. The time delay prevents the Control Range from causing motion jerkiness as
the signal varies due to normal operator load movement.

For ease of alignment, adjust the time delay to the minimum (CCW position) while adjusting the range.

Position the operator with an operating transmitter at the desired range limit.

Turn the Range adjustment until the Range indicator LED illuminates. Slowly rotate the Range adjustment
clockwise until the Range indicator extinguishes. Note that a voltmeter may be connected to the test points
to monitor the voltage for the set point.

Test the operation of the Control Range by having the operator with the transmitter move in and out of
range in all directions and readjust the Range adjustment as needed to achieve the desired range limit . Note
that the time delay holds the Range LED off for about 1.5 seconds after the operator goes out of range.

When the range is properly adjusted, increase the time delay to the desired value. The adjustment may be
set from 1.5 to 10 seconds. Laird recommends a longer time delay to prevent the system from falsely
activating due to the normal dynamics of the operator running the crane.

7.5 Receiver Troubleshooting

7.5.1 General

Refer to Figure 6, Figure 8, and Figure 14 for the receiver layouts.

The 21R14A, 21R22, and the 22R08A have diagnostic LEDs plus a LED for each output relay to aid in isolating

a problem if one occurs. The 22R08A and 21R14A receivers have ‘OUTPUT’, ‘SIGNAL’ and ‘POWER’

diagnostic LEDs on the front of the receiver case. The 21R14A and 22R08A series use a single circuit board for

the receiver and decoder. The 21R22 receiver has ‘SIGNAL’ and ‘POWER’ diagnostic LEDs on the front of the

receiver case and it uses a RF/Decoder board and a Relay board.

The following table describes the diagnostic LEDs.

When the 21R22 is not receiving a valid signal, an OFF relay pulls in, which ensures that power is removed
from the mainline contactor on the crane.

When the receiver is receiving a signal in normal operating mode, the OPR relay drops out and the MLC
relay pulls in, allowing the main contactor on the crane to energize.

Note the 21R14A uses one MLC relay.

7.6 Receiver Testing

Note: Before testing, we recommend isolating power to the crane and that all tag/lockout procedures

applicable to your facility are applied.

Follow these steps when troubleshooting the Command Pro receivers.

1. Check the POWER indicator. If POWER is not illuminated:
a. Make sure the power switch on the right side of the receiver cabinet is in the ON position.
b. Check for AC input power between terminals X1 (X1/+DC-SW for R14A) and X2 of the

terminal strip. If AC power is present and the POWER on LED is not on, the problem may
be in the Relay board.

2. Ensure the transmitter is OFF.
a. Switch the receiver power switch off and then on. If no indicators come on after 1 second,

the microprocessor circuits are possibly defective. The RF/Decoder board may also be
defective.
