1.0 Installation Instructions: 
1.     The F21 and F24 receivers should be mounted in a location that is convenient to the control    
box and is securely attached to the equipment.   The F21 receiver measures 7.37” L x 3.37” W 
x 7.10” D and is mounted by drilling one 5/16” (8mm) hole and the F24 receiver measures 10” 
L x 6.5” W x 4.5” D and is mounted by drilling three ¼” (6mm) holes (see diagrams below).  
Mount the receiver using the supplied hardware. It is best to keep the receiver as far away 
(approximately 6 feet) from variable frequency drives and the motors and cables attached to 
them to avoid interference.

2. The F21 receiver wires are color coded, and the F24 receiver wires are numbered. The wires are 
identified on the label on the top of the receiver and on the wiring diagrams on page 15 of this 
manual. 
3. All the contacts in the receiver are “dry” relay contacts.  This means that is there is no internal 
source of power to the contacts.  You will need to connect the “common” lead for each output 
or set of outputs that you plan to use to the same power supply that it would be connected to in 
a corded pendant.  For most cranes this wire is X1 (the 120 volt AC control transformer “hot” 
side).  Some cranes have separate hoist/trolley and bridge transformers.  In these cases, 
connect each transformer’s X1 to the function(s) it powers.  There is no requirement that the 
common leads be connected to a 120 volt AC supply- these are “dry” relay contacts; whatever 
you put into the common wire, comes out each function’s wire when that relay closes.  The 
only restrictions are, do not exceed 10 amps or 250 volts AC.  For DC applications call the 
factory at 1-800-382-3558.  
4. Put 2 AA alkaline batteries into each transmitter.  For F21-2 button models, remove the 4 
screws on the back of the transmitter.  Insert the batteries as indicated inside the unit.  Replace 

6 
the screws.  For the F21-4, F21-6, F24-6, F24-8, F24-10, and F24-12 button units, remove the 
battery compartment cover on the bottom of the unit by unscrewing the thumb-screw.  Insert 
the batteries as indicated on the label inside the battery compartment.  Replace the cover and 
tighten the thumb-screw until the cover is fully seated against the transmitter body. 
5. Test the system thoroughly before releasing it for use. 
2.0 Operation Instructions: 
2.1 Battery Indicator: 
The LED on the front of the transmitter indicates the condition of the batteries.  It will 
flash green during operation if the battery power is sufficient, and will flash red if the battery 
power is low.  If the LED is flashing red, or if the operation becomes erratic, or will only 
work from a short distance, replace both batteries with new AA alkaline batteries using the 
procedure given in section 1.0. 
2.2 Fuses 
There are three fuses in the F21 series receivers and six fuses in the F24 series receivers.  
On all models there is one fuse in the AC power line that operates the receiver (0.5A, 250V), 
and one is in the internal 12 volt DC supply (1.5A, 250V).  In the F21 receivers there is one 
fuse in the COM wire.  On the F24 series radios there are four fuses in the COM wires (10A, 
250V).  These fuses are for relay contact protection in the event of a short circuit in the 
equipment being controlled by the radio. To replace a fuse, push down the fuse cover and 
turn counter-clockwise ¼ turn with thumb and forefinger or a flat-blade screwdriver.  
Remove the fuse from the cover and insert a new one of the same rating.  Insert the fuse and 
cover into the fuse holder, press down, and turn clockwise ¼ turn.  For protection from fire 
hazard, damage, or injury, always replace a blown fuse with one of the same rating. 
2.3 Start Procedure for the F21-2S and F21-2D: 
1. Put the green magnetic safety key into its slot in the front of the transmitter. 
2. Use the UP and DOWN pushbuttons to control the equipment. The first time that either 
button is pressed, the mainline contactor will engage.  If there is no mainline contactor 
provided on the equipment being controlled by the radio, the Main (red) wire does not 
need to be connected to any of the equipment controls. The model F21-2D has two-step 
buttons; pressing them to the first detent will activate the equipment at the slow speed, 
and pressing them fully will activate the equipment at the fast speed.   
3. Press the STOP button to stop movement immediately and drop out the mainline 
contactor, if one is used. 
4. Remove the green magnetic safety key whenever the transmitter is not in use to prevent 
unintentional operation.

3.0 Safety: 
EMERGENCY PROCEDURE:  In case of emergency, perform these steps IN ORDER. 
1. Press the red STOP button. 
2. Remove the green magnetic safety key on F21-2 button models only or turn the 
green key to OFF on the F21-4, F21-6, F24-6, F24-8, F24-10, and F24-12 button 
models. 
3. Switch off the main power to the equipment. 
4. Contact qualified service personnel. 
This manual is intended for the user as a general reference only.  Please consult your distributor 
for specific installation or assistance with technical issues.  In an industrial environment, safety 
must always be a top priority.  Persons responsible for installation, operation, and maintenance 
must make certain that both their actions, and the equipment on which they work, are safe.  
Following are a list of safety rules that must be followed when working with TELECRANE 
products, as well as cranes and industrial equipment in general.  This list is not intended to be all-
inclusive.  General industrial safety rules must always be followed.  If there is any doubt about 
how to proceed, always take the safest course of action.   
9 
- Only qualified personnel who are familiar with the product and who have read 
these safety instructions should install TELECRANE products. 
- Before installing or operating this product, read this manual thoroughly.  If you 
have any questions, please contact ITL. 
- All sources of power to the crane or controlled equipment must be de-energized 
and locked out before installing the unit. 
- Before installing the receiver, energize it in a controlled environment (such as an 
office) where it can be tested and set up properly before it is mounted in the field.  
If it does not work exactly as intended, fix the problem and test it again. 
- Before installation, be certain to understand the electrical functioning of the crane 
or equipment, including the sequence and relationship of motions and contactors. 
- Fall prevention devices should be used when anyone is working at an elevated 
height. 
- The receiver must be securely attached and located where it will not be hit by any 
moving part of the building, crane, or load. 
- The crane or hoist must be equipped with limit switches for each motion and a 
main power contactor that cuts off all power to the motors of the crane when it is 
de-energized. 
- Special care must be taken for magnets and other load-carrying devices to ensure 
that if the crane is de-energized the load remains supported. 
- The receiver must be located so that it receives sufficient signal strength from the 
transmitter. 
- Operating any piece of equipment in an industrial facility can be dangerous; 
therefore, adequate training will need to be provided to operators of cranes or 
other equipment that uses a TELECRANE product. 
- At least once each shift, check the amount of power remaining in the transmitter 
batteries. If it is low, change both batteries before beginning operation.  
Operating the unit with excessively discharged batteries can be unsafe. 
- The safety key should be removed from the transmitter whenever it is not in use 
and should only be issued to authorized personnel. 
- All TELECRANE Radio Remote Controls are tested before they leave the 
factory.  However, they should not be used in dangerous situations or in a manner 
such that damage might result. 
- Although the transmitter is very durable and weather-resistant, precautions should 
always be taken to limit its exposure to weather, physical impact, and corrosives. 
- After use, or if the unit will not be used for a long interval, turn off power to the 
crane or equipment and remove the safety key from the transmitter. 

10 
- Remove the batteries from the transmitter if the transmitter will not be used for 
two weeks or longer. 
- Transmitters that are not in use, including spare transmitters, should be stored, 
with batteries removed, and secured to prevent accidental operation. 
- Before each shift, check that the limit switches function correctly and that 
movement corresponds to the button being pressed on the transmitter. 
- Do not use the equipment during lightning storms or high electrical interference 
conditions. 
- In general only authorized service facilities should perform maintenance on this 
product. 
- Ensure that anyone performing maintenance on the crane or equipment is 
thoroughly familiar with its operation. 
- Power should be shut off to the crane or equipment before any maintenance 
begins, unless absolutely required for troubleshooting the unit.  When the power 
is on, use extreme caution.  High voltage or unexpected movement could cause 
death or severe injury. 
- Only certified maintenance personnel should attempt a repair more involved than 
the swapping of printed circuit boards.  Improper repair can compromise the built-
in safety features and cause unexpected operation and damage. 
- This product uses two AA alkaline batteries.  When replacing batteries, both must 
be replaced at the same time. 
- ITL does not recommend use of nickel-cadmium or nickel-metal-hydride batteries 
due to voltage characteristics that cause a sudden loss of power when discharged.  
They also have less capacity than alkaline batteries and therefore will not last as 
long. 
4.0 Trouble Shooting Common Mistakes In Installation: 
 Receiver dead:  Is 120 volt AC applied between X1 and X2 wires?  On the F21 
models these are the BLACK and BROWN wires; and on the F24 models they are 
wires 1 and 2.  You must provide both the hot and the neutral sides of the control 
transformer secondary to power the unit. 
 Does the equipment have a mainline contactor:  Not all equipment has a 
mainline contactor.  The best way to determine if your equipment has a mainline 
contactor is to check whether there is a START and STOP on the corded pendant. 
If the equipment does not have a mainline contactor then these wires do not have 
to be connected.  On the F21 models this wire is the MAIN wire and on the F24 
models this is MAIN-IN (3) and MAIN-OUT (4).  The MAIN wire on the F21 

11 
models will be hot when mainline is on; this wire has to be terminated with a wire 
nut or isolated.        
 Relays close but there is no movement from the crane:  Are the COMMON 
wires hooked up properly? The receivers have “dry” contacts.  Even though X1 
and X2 have been applied to power the receiver, you still need to apply power to 
the common side of the relay contacts in order to get power to your contactors.  
On the F21 models the COM wire on the diagram is separate from the power 
wires and on the F24 models each COM wire is completely isolated from the 
others as well as the power wires.  In most cranes, the COM wires will be 
connected to the X1 supply. 
If you have any problems or questions not covered above, please call ITL at 1-800-382-3558.   
5.0 Programming options: 
5.1 All units:   
- Auto-shut-down time.  An auto-shut-down feature is available on all models.  If the 
radio has not been used for a period of time the receiver automatically drops out the main 
line contactor. The default setting is 1 hour for the F24 Series and “Never” for the F21 
Series.  Auto-shut-down times can be set between 0 and 4 hours. Typical selections are 
available on the programming data sheets in the back of this manual. 
- Pushbutton options.  Each pushbutton is set by default to momentary (relay closes when 
a button is pressed and opens when released), and interlocked in opposed motion pairs 
(UP-DOWN, EAST-WEST, SOUTH-NORTH).  When set as momentary, they can be set 
as un-interlocked.  They can also be set as toggle (press once to close relay, press again to 
open) or as On-Off pairs (press On to close relay, press Off to open relay).  When 
programmed as toggle or On-Off, they will be set as controlled by Stop (opening 
automatically when the STOP button is pressed). They can be specially rewired by the 
factory for uncontrolled by Stop (unaffected by STOP button); please call for more 
information.   
5.2 Models F21-2D, F21-4D, F24-6D, F24-8D, F24-10D, and F24-12D: 
- Acceleration delay.  Delay between actuation of relays for the first and the second 
detents of the two-step button can be programmed on the two speed models. This delay 
time can be set between 0 and 4 seconds; default is 0 seconds. Typical selections are

5.3 Models F21-4S, F21-4D, F21-6S, F24-6S, F24-6D, F24-8S, F24-8D, F24-10S, F24-10D, 
F24-12S, and F24-12D: 
- R0 function.  On the F21 models the R0 relay operates when the green key is turned to 
START after the unit is already started.  On the F24 models the R0 relay operates when 
the START button is pushed after the unit is already started.  It is by default set to 
momentary (closed when START key is turned on the F21 models or START button is 
pressed on the F24 models, open when released).  It can also be set to toggle (turn the 
START key once to close, turn it again to open on F21 models or push the START button 
once to close, then push the button again to open on the F24 models), or inching (does 
not activate the R0 relay, but instead only allows pushbuttons pressed after turning the 
key to remain on for a preset length of time, no matter how long the button is held).  For 
inching, the inch time may be set from 0.05 to 0.8 seconds in 0.1-second increments. 
Typical selections are available on the programming data sheet. 
5.4 Other Programming options for the F24 UP/DOWN 2 Step Buttons: 
 Dual Motor.  When the first detent of the button is reached the first step relay turns ON, 
when the button is fully depressed the second step relay turns ON and the first step relay 
turns OFF.  When the button is released back to the first detent, the first step relay will 
turn ON until the button is released. 
 Dual Motor (1).  Works the same as Dual Motor, with the difference being the first step 
relay will not activate when returning from fully depressed to the first detent.  The button 
must be completely released and repressed in order to activate the first step relay again.  
 Combination.  When 2 buttons are depressed simultaneously, it will result in a third 
relay output that is set to toggle. The relays of the two buttons depressed will not engage, 
instead a third relay will engage. This feature is designed to suit some special 
applications such as lighting systems.  Combination setting is prohibited for magnetic 
devices.  Combination setting is always set to controlled by stop. Uncontrolled by stop is 
not available. 
 3 Speeds.  The START button can be used to control a third speed.  Once the motion 
button (either up or down) is fully depressed, a third speed can be obtained by pushing 
the START button.

6.0 Internal Horn option: 
 This section describes the Internal Horn Option on the following model numbers: 
F24-6S-HN    F24-8S-HN    F24-10S-HN 
F24-6D-HN    F24-8D-HN    F24-10D-HN 
F24-12S-HN               F24-12D-HN                                    
Instructions for use: 
The Internal Horn Option operates automatically with usage of the TELECRANE F24 Series 
Radio Remote Control in which it is installed.  F24 models ending in ”-HN” contain this option.  
It will sound the horn on two conditions: 
- The horn will sound for approximately two (2) seconds upon initially pressing          
START in order to provide a warning that the crane or other equipment is being 
started; 
- The horn may be sounded by pressing START at any time after startup, regardless 
of whether a motion button is being pressed.  The horn will sound as long as the 
START button is pressed.  (This may be eliminated: see Adjustments, below) 
Adjustments: 
There are two (2) small DIP-style rocker switches near the lower edge of the Horn printed circuit 
board.  This board is mounted inside the front cover of the receiver.  These switches constitute 
the only adjustments available on the Internal Horn Option.  As shipped, both switches are set to 
“ON”. 
SOUNDING HORN AFTER STARTUP: The switch closer to the edge, numbered “1”, 
controls whether pressing the START button after startup sounds the horn.  If it is desired to use 
the R0 relay without the horn sounding, press the rocker switch toward the “OFF” or “OPEN” 
position.  To resume sounding the horn on R0 activation, press the switch toward the “ON” 
position.   

14 
VOLUME CONTROL:  The switch toward the middle of the board, numbered “2” controls the 
volume level of the horn.  To reduce the volume level, press the rocker switch toward the “OFF” 
or “OPEN” position.  To restore full volume level, press the switch toward the “ON” position.
