Version 2.0
When the transfer switch is in the ‘REMOTE’ position, the manual controls should be disconnected and all power
should be t
ransferred to the radio control relays. When the transfer switch is placed in the ‘MANUAL’ position,
manual control of the equipment should be restored. The equipment may now be controlled as it was prior to
installation of the radio controls.
Figure shows a typical transfer switch wiring setup. The transfer switch also
contains an ‘OFF’ position. In this position, all circuits are disconnected from both remote and manual controls.
Figure 20: Typical Transfer Switch Wiring
When switching the transfer switch between remote and manual control, observe the following precautions:
•
Do not transfer control of a crane with a load lifted. Always set down all loads prior to changing the
position of the transfer switch.
•
If the crane is equipped with a magnet, it shall be set in the drop position prior to changing the position of
the transfer switch.
•
Press the ‘STOP’ button on the OCU and temporarily remove the Battery Pack.
6.7 Antenna
The antenna may be internal, mounted directly to the connector on the MCU enclosure or remotely mounted via
an extension cable.
A directly mounted antenna must: (1) have a clear line of sight to the operating area, (2) not be mounted within a
secondary enclosure, and (3) not be mounted against any steelwork that would de-tune it.
If the antenna is remotely mounted, connect the extension co-axial cable to the connector on the MCU enclosure.
