Version 3
There is a Tilt time extension that can be configured, if required, that allows the operator to extend the tilt time by
another configurable time of up to 30 seconds.
Typically, the tilt settings are configured so that if an angle greater than 45 degrees is exceeded for more than 5
seconds, the unit shuts down.
If an operator has some process where he does bend over, the Tilt time extension is added and set for 30
seconds to allow the process to be completed without a penalty.
Note that this feature is more closely related to machine and vehicle operation than crane use.

IR Enable
The IR Enable function is an optional feature.
This feature requires the OCU to be taken within a closely defined zone of coverage from an IR (infrared)
transmitter before the OCU can be enabled.
The enable zone is typically used to ensure that an OCU is not switched on before an operator has moved into a
region where it is safe to operate the crane or machine. Specifically, it ensures that the OCU cannot be enabled
when it is away from a crane or machine. An example of this function is to prevent a situation whereby the OCU
radio can communicate through walls to the crane or machine, but it is inadvertently operated in an adjacent room
such as a cafeteria or maintenance workshop.
The IR transmitters shown below are mounted either singly or in multiples as required to achieve the required IR
coverage zone.

The IR beam is specifically encoded to address only the target system and is fully secure.
The OCU has an IR sensor mounted on it and the LRC-M and LRC-L can have the sensor in any location. The
product shown above right has the sensor to the right of the Stop switch.
