TM70/3-10 & i-Kontrol Console RC System

U035.3-TM70_Console_Sys

16.1 Infrared Sensor

As the system or operator moves, an infrared sensor located in the TM70 remote control

transmitter (Figure 23) receives infrared information as it is transmitted from the LA70 IR

module. The remote microprocessor gathers the sensor information and checks for the crane or

machine ID. If the operator is too far away from the LA70, the sensor stops receiving an IR

signal and the TM70 transmitter LED begins to flash RED—belly box transmitters also sound an

audible warning—letting the operator know that the sensor must be moved back within signal

range within four (4) seconds (the system default). If the operator fails to get back into range

within the allotted time, all active commands are stopped; however, the RF communication is

maintained with the receiver and remains in control of the main-line contactor.

Figure 23. Transmitter IR Sensor Location

The operator must move the TM70 transmitter into the defined working area, or zone, to re-

establish control of the crane or machine. Once the transmitter returns to the working area,

control of any machine movement previously established is ignored and remains disabled until

all movement controls are returned to zero. If the remote is equipped with a display, the display

will read OUT OF RANGE when appropriate.

Modes of Operation

The remote control unit has four (4) modes of operation defined in the EEPROM. The infrared

range of operation is referred to as the Work Zone. These modes are:

1. Range Limiter Only at STARTUP (Electronic Key): The transmitter must be in the infrared

range of operation (Work Zone).

2. Range Limiter Only Operation: The transmitter can be started anywhere inside or outside of

the Work Zone, but the there is no control until the transmitter is within the infrared range of

operation and all movement controls are at zero command.

3. Range Limiter at STARTUP and Operation: The transmitter must always be in the infrared

range of operation (Work Zone).

4. Range Limiter Only as an Output Relay: The transmitter will not show In range or out of

range in the transmitter itself. No order is masked. Information is sent to the receiver to

process as an output relay or as a condition to the relay table.
