User's Manual

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

available on the programming data sheet.
