- 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
