movements simultaneously. When these bridges work simultaneously and make the same

movements, they are called tandem cranes and can be directed from a single transmitter.

The installation consists of a set of two receivers and two transmitters, one master and the

other slave, which permit the operation of two cranes individually or at the same time from a

transmitter (master).

Remember that the tandem operation is delicate, as there may exist safety devices (limiters

of travel, anti-collision systems, etc.), which may affect only one crane, stopping, while the other

crane remains wholly operative.

NOTE: Remember that the slave transmitter only turns on in position 2 and the master can only

be turned on if we have the selector of crane selection in the same position as it was in when

disconnecting the unit. If we turn on the transmitter with the selector in a different position, on

extracting the button and pushing start the Led will blink red once and will then turn off. If this

occurs, put the crane selector in another position, extract the button and push start until the

When it is necessary to

carry out a tandem

operation, the operator

of the master

transmitter must

request from the

operator of the slave

transmitter the

liberation of the slave

receiver.

To do this, with the

transmitter turned on,

push the liberate

button, (L) in position

10, and push start for

about 2 seconds. The

led will blink rapidly in

amber and will turn off.

In this state the slave

transmitter is

inoperable.

For the slave

transmitter to work

with the slave receiver.

Extract the Stop

button and push

start; the led will light

up green.

NOTE: If the slave

transmitter turns on

and its corresponding

receiver does not

receive a signal it is

probably occupied with

the master transmitter

to whom we must

request the liberation

of slave receiver

(deactivating the

tandem mode)

For the master

transmitter to work

with its master

receiver, with the

transmitter turned

on (green led), put

the selector of the

master transmitter

in position 1; the

Led will blink red

and press start for

about 4 seconds;

the Led will blink

rapidly in amber and

will light up green.

The master

transmitter will only

work with the master

receiver.

We direct the two

receivers with the master

transmitter. To work:

-With the two receivers

simultaneously, with the

transmitter turned on (

green led), put the selector

in pos. 1+2 and push start.

-Only with the slave

receiver, with the

transmitter turned on (

green led), put the selector

in position 2 and push

start.

-Only with the master

receiver, with the

transmitter turned on (

green led), put the selector

in position 1 and push

start.

Once the tandem

operation is finished,

to go back to working

separately, with the

transmitter turned

on ( green led), put

the selector of the

master transmitter in

position 1, The Led

will blink red and

push start for about

4 seconds; the Led

will blink rapidly in

amber and will light up
