the operator overlooks the indicator lights 87, 88 and 89 and determines if the machine has failed in its place or in front of or behind it, seen in the working direction, has stopped.

If, for example, a heater in the transfer mechanism 18 activates the detector H, which in turn lights up the lamp 54 H, the signal from the detector triggers the operation of the counter 58 and the timer 59 and the monitoring module 55 H for the relevant error as well as the Modules 56 and 57 for the stretching machine and the machine. In this case, as in other cases, the detector sends a signal to the main controller, which controls the. Machine stops. The operator, who sees the lamp 54 H glowing on the panel 54, notices the code number 8001 and presses this number into the selector 71 (but not when the machines are working on automatic) and displays the instructions for correcting the error on the screen.

The instructions can be used to inform the operator of the sequence of steps in a simple manner When the young hay is found, it triggers the detector Has. The instructions can also include several possibilities of incorrect operation of a machine, who experienced the inhibition, and the code numbers for them Deliver alternatives. The staff can enter the code numbers in the selector 71 and thus receive additional instructions to prevent further such inhibitions.
