The transmitter PIN code protects the transmitter so that only authorised persons can use it.

Furthermore, certain functions can also be protected by a PIN so that only authorised persons can use them.

The menu item “Set PIN” is used to activate the various PIN levels of the transmitter and set the various PINs.

Overview of the PIN levels:

─     Level 0: Transmitter PIN code. If PIN level 0 is activated on the transmitter, the transmitter can only be switched on if the corresponding correct PIN is entered when switching on the transmitter.

When switching on or logging in the transmitter, the PIN prompt appears if any of the PIN levels in the transmitter are activated. If the PIN for PIN level 0 is entered, the transmitter can then be switched on or logged in.

Pin level 0 is only saved in the transmitter. This means that the corresponding PIN prompt appears no matter which receiver the transmitter is logged into.

─     Level 1: Override travel limit switch. On the receiver, the function “Override travel limit switch” is protected by a PIN. The travel limit switch can only be overridden if PIN level 1 is additionally activated on the transmitter and the corresponding correct PIN has been entered during switching on or logging in of the transmitter. PIN level 1 automatically also contains PIN level 0.

When switching on or logging in the transmitter, the PIN prompt only appears if one of the PIN levels in the transmitter is activated. If the PIN for PIN level 0 is entered, the transmitter can be logged in, but the protected function “Override travel limit switch” will remain locked. If the PIN for PIN level 1 is entered at the PIN prompt, the transmitter can be logged in and the direct access button “Override travel limit switch” can be pressed.

─     Level 2: Switching off the load limiting system. On the receiver, the function “Switch off load limiting system” is protected by a PIN. The load limiting system can only be switched off if PIN level 2 is additionally activated on the transmitter and the corresponding correct PIN has been entered during switching on or logging in of the transmitter. PIN level 1 automatically also contains PIN level 0.

When switching on or logging in the transmitter, the PIN prompt only appears if one of the PIN levels in the transmitter is activated. If the PIN for PIN level 0 is entered, the transmitter can be switched on, but the load limiting system remains switched on and the crane can be operated with reduced maximum load capacity. If the PIN for PIN level 2 is entered at the PIN prompt, the load limiting system is switched off and the crane can lift with maximum load capacity.

─     Level 3: Combination of level 2 and 3. On the receiver, the functions “Override travel limit switch” and “Switch off load limiting system” are protected by a PIN. The travel limit switch can only be overridden and the load limiting system can only be switched off if PIN level 3 is additionally activated on the transmitter and the corresponding correct PIN has been entered during switching on or logging in of the transmitter. PIN level 3 automatically also contains PIN levels 0, 1 and 2.

When switching on or logging in the transmitter, the PIN prompt only appears if one of the PIN levels in the transmitter is activated. If the PIN for PIN level 0 is entered, the transmitter can be logged in. If the PIN for PIN level 3 is entered, the transmitter can be logged in, the direct access button “Override travel limit switch” can be pressed, and lifting can be performed with the maximum load capacity.

The protected functions in the receiver are configured and administered at the factory.

Thus, the functions are protected no matter which transmitter is logged into the receiver (e.g. in the case of a replacement transmitter). However, the PIN required for unlocking is saved in the transmitter, and can thus be set specifically for the transmitter in question.

The protected functions can only be operated if the respective PIN level has been configured in the receiver at the factory and the same PIN level is activated on the transmitter. If the correct PIN for the PIN level is then entered when switching on or logging in the transmitter, unlocking is possible. The configuration in the receiver cannot be adapted. For the transmitter, the PIN levels can be activated in the “Settings” menu.

If a crane with protected functions in the receiver is operated with a transmitter without activated PIN levels, the protected functions cannot be unlocked.

PIN level 0 is however saved in the transmitter. This means that the PIN is prompted on this transmitter no matter which receiver the transmitter is logged into. Conversely, the crane can be operated without entry of a PIN if a transmitter with no activated PIN levels is connected to the receiver.

Note regarding safety:

The menu item “Set PIN” is accessible in the service menu, which can be opened with the service menu code “0055”. The menu item has no further protections. This means that the PINs for the PIN levels cannot be accidentally changed since they lie in the protected service menu, however there is no absolute protection against misuse, deactivation of the PIN levels or changing of the PIN.
