7.4.3 Transition to Active Mode
From Passive Mode the OCU can be moved into Active (Transmitting) mode, this stage involves some critical
Safety tests and a positive transition into active machine controlling mode.
The STOP switch has two contact elements under it, and they are tested every time the OCU is moved into an
Active mode, additionally all switch elements are tested at this phase to ensure that none of them are activated,
the start sequence from Passive Mode is; Press the Stop switch and then press the Start switch within 3 seconds.
Table 4 Active Mode LED Sequence
At this point the OCU is operative and the target machine will be under direct control, verify the connection by
activating a non-motion function such as the Horn button.
Test all functions briefly at the start of the work session.
WARNING
Before attempting to use the system, verify the target crane or machine you wish to operate is
under the direct command of your OCU. This is accomplished by operating a non-motion OCU
function such as the horn and observing that the horn sounds on the targeted crane or machine.
Failure to implement the above may result in serious injury or death to personnel and damage to
equipment.
