•
Keep the Request button pressed until the status indicator on the crane indicates the desired status.
(** = This function is configuration-dependent. If "
automatic release
" is configured, the MCUs are released automatically as
soon as the position of the
MCU selection switch
is changed)
9.3.1 Operation Following a REQUEST
Once one or more cranes have been requested, it is then possible to switch between the various available
combinations of cranes by altering the position of the electronic
selection switch on the OCU
. Depending on the
configuration, switching between combinations of cranes is possible during operation of the cranes, thus allowing,
for example, "corrections" during parallel travel without having to release cranes and then request them again. In
this case, all the MCUs locked on to an OCU remain assigned to that OCU, regardless of the change in the
position of the selection switch.
Alternatively, it is also possible to automatically release MCUs when the position of the MCU selection switch is
changed. MCUs which are assigned to an OCU but which are not currently being controlled by that OCU ignore
all commands.
9.4 RELEASE Function
The Release button is used to release the MCU(s) currently selected by the OCU selection switch.
•
An OCU can only release MCUs which it has previously requested.
•
MCUs which are not assigned to a specific OCU cannot be released by that OCU.
•
One or more MCUs can be released at the same time.
•
Sequential releasing of multiple MCUs, e.g. first MCU 1 and then MCU 2, etc., is also possible
•
Keep the Release button pressed until the status indicator on the crane indicates the desired status.
** = Depending on the system configuration, three different types of release are available and can be used
individually or in any combination:
o
Manual release, only by pressing the Release button
o
Automatic release of the assigned MCU(s) by switching off the OCU
o
Automatic release of a MCU following switchover to a different MCU (by changing the position of the
MCU selection switch)
9.5 Select Status Indication on the Cranes
Clearly visible lamps must be connected to the MCUs to indicate that an OCU is locked on to a MCU. The number
of lamps used must correspond to the number of O
CUs + 1. The additional lamp is used for the "MCU free”
status. The default status of this lamp is ON, indicating that the MCU in question is not currently assigned to an
OCU and can thus be requested by any OCU. Once a MCU locks on to an OCU, the lamp for that OCU lights up
on that MCU and the "free" lamp goes out.
One lamp must always be lit. If this is not the case, one of the lamps is defective. The activation of the lamps can
be achieved by means of appropriate wiring of the independent relays. Control of the lamps using independent
relays ensures that the lamps are also controlled in the passive state.
The wiring of the lamps is documented in the wiring diagrams provided with your system.
9.6 Example Configuration
The diagram below shows the possible control combinations in a multi-crane system consisting of two OCUs and
two MCUs. Each OCU can operate with either MCU1 or MCU2 or both MCUs.
