TM70 – TANDEM OPERATION
13.1 - INTRODUCTION
This option allows the operation of two cranes individually or in tandem by using one transmitter by
the selection of ID codes, which determines the mode of operation. For tandem applications both
receivers are required to scan the radio channels in order to receive radio signals from different
transmitters.
Once a mode has been selected, the access to the selected receiver or receivers will be blocked for
other transmitters, until they have not been liberated by the transmitter having the control. This
blocking is maintained even in case that the equipment is switched off.
When a selection is made with the transmitter disconnected, the transmitter will not start and shows
in the LED that the selection made is not correct with 0,4s red pulses. The transmitter must be
switched off and restart it with the selection with which it was switched off.
A Tandem operation with cranes is always delicate.
Remember that there are safety devices, (limit switches, anti collision guard systems, etc.),
which can affect and stop one of the cranes, while the other continues working.
In the tandem systems with LCD Display option, in the 1
st
line of the display will be shown the crane
1 name and in the 2
nd
line the crane 2 name. With the selector switch in position 1+2 both names will
be shown.
You can personalize the name of the 2 cranes following the description in ANNEX A in this manual.
The modified name of the crane in the transmitter will not be updated in the receiver
EEPROM. In order to do it, please copy the new information located in the transmitter
EEPROM into the receiver one.
IMPORTANT REMARK
:
The frequency set up of tándem systems supplied from IKUSI is by default F1= CB / F2 = CB+4
By default CB = CT.
