TM70 – “PITCH & CATCH” OPERATION
12.1 - INTRODUCTION
This option allows the operation of one crane by two transmitters, through the selection of ID codes,
which determine the mode of operation. For this application, the SCAN option for the receivers is
required in order to receive transmitters in different channels.
This mode of operation consists of the use of a crane by two different transmitters. The first
transmitter governing the crane gets hold of the crane until it as switched off (in principle exactly as
the First come – First served mode of operation). In the event of pressing the STOP pushbutton, the
other transmitter is switched on and the START order is being pressed, the second transmitter gets
hold of the crane without falling the STOP relays. This way, users of the same crane with different
transmitters can pass each other the crane without falling the STOP relays. As the START
pushbutton must be pressed when transferring the crane if the START relay has got a connected
Horn, when the transfer is done an audible sound can be produced.
Pitch & Catch operation is always delicate, given that the receiver is FREE every time the
STOP button is pressed or there is a radio link failure.
