Radio Control System
2.2.5 Catch – Release – Tandem Option
Via the Catch – Release – Tandem Option two or more radio transmitters can control
several cranes alternately.
Each crane is equipped with a radio receiver that can receive and monitor all transmitter
frequencies.
After activating the receivers all transmitters have equal access to the radio control
system.
Release crane
1. Enter the “Release“ command on the transmitter.
The release applies to all active cranes.
2. Press the STOP switch on the transmitter.
The access rights for the crane(s) are cancelled. Crane control can be taken over by
another transmitter.
Take over crane
1. Turn rotary switch on the transmitter to the respective position ("A" or "A + B" or
"B").
2. Enter the ”Catch“ command on the transmitter.
The transmitter with control over the crane(s) retains the access to the receiver until the
operator has issued the "Release" command.
Operating Example
Transmitter 2 has taken over the crane(s). Transmitter 1 is to be given control over the
crane(s):
1. Enter the “Release“ command on transmitter 2.
2. Press the STOP switch on transmitter 2.
3. Unlock the STOP switch of transmitter 1 by turning, and press button.
4. Turn rotary switch on transmitter 1 to the "A" or "A + B" or "B" position.
5. Enter the “Catch“ command on transmitter 1.
Transmitter 1 now has sole access to all crane functions.
Notes:
– If a receiver has already been adopted by a transmitter can be displayed via a lamp
on the crane or machine.
– If the operating voltage of the receiver fails the receiver returns to the starting
condition in which it can be adopted by any transmitter. If necessary the receiver
must be adopted anew.
– If the transmitter is deactivated without the command “Release“ having been issued,
the other transmitters have no access to the receiver(s). The starting condition
described above can only be resumed by deactivating the operating voltage at the
receiver.
