Master-Slave systems (Tandem Control)
Master-Slave systems comprise 2 sets of remote controls,
where the 2 machines are normally used independently. But
when required, one transmitter (the Master) can take control
of both machines and control them together. The most
common application is in overhead travelling cranes, where
the two cranes can be used individually, but driven together
when lifting a long or heavy load.
The handover of control from one transmitter to the other is
safely managed with a Take/Release system that requires
the agreement of both operators.
Available in the LKNeo, SK, A8, AIR, and PJE series.
Multi-Receiver Systems
Multiple receiver systems allow one transmitter to control
equipment in 2 or more locations, each of which is fitted
with an individual receiver. There are several different
synchronisation options available:
One-to-One Link
A transmitter can control up to 15 x receivers, but only
one at a time. Typically the transmitter has a rotary switch
fitted to make the receiver selection. The transmitter must
be re-started after changing the selection.
Line-Up-Link
Up to 4 x Receivers can be operated from a single
transmitter as a group or individually. If communication is
lost with one receiver, then all receivers stop. This suits
many lifting applications, for example.
Available in the LKNeo, SK, A8, AIR, and PJE series.
Pitch & Catch Tandem Systems
Pitch & Catch systems allow 2 operators to control a single
machine, and pass control backwards and forwards in a safe
manner. A Take/Release methodology is used that requires
the agreement of both operators, and only one operator is
ever in control at one time.
Available in the LKNeo, SK, A8, AIR, and PJE series.
Spare Transmitters
Spare transmitters are available for all Autec remote
controllers. In all cases, the transmitter and receiver pairs
are assigned unique codes, with the exact methodology
varying between series. Putting a spare transmitter into
service is a relatively simple task, but one which is done
safely - managing the serious safety risk that would be
posed by having two simultaneously operating transmitters.
Available for all series.
Supervised Operator Systems
(SOS) also known as
Basket/Observer systems
Most commonly used on elevating work
platforms, the SOS is a special-purpose
remote control system that allows a
Supervisor to take control of a machine if
the Operator is injured or disabled, or his
controller is damaged. Furthermore, the
Supervisor always has a fail-safe STOP
control available at all times in case he
sees a hazard that the operator does not.
