    The High Speed controlled by MCS, instead, is not assigned by any parameter, but it is read by MCS during the test of the stop distance. In fact, during the test of the stop distance, when MCS commands the stop of the machine to measure the distance, it records even the speed reached by the machine.

Instead, if the object is removed from the active detection area, MCS can continue moving the machine in High Speed.

  • Page 88 Only the next release causes the exit from the state of STOP MCS. This action is signalled by the blinking of the big yellow LED present on the front part of the receiver. In this condition, a further pressure on the downstroke pedal causes the downstroke of the machine with the sensors of the front area in blanking status and those of the rear area in exclusion state.
