Follow the procedure step by step to correctly diagnose the problem. Take particular care with the
checks highlighted by circled numbers, which are described in detail below:
(1) Check the earthing of the machine using a tester to measure the resistance between the ground
pin on the power supply cable and the ground node to which the receiver is connected inside
the display. The value must be less than 1 Ohm.
(2) For machine positioning layouts, use the following diagram as a reference.
where:
1. The distances are in centimeters.
2. The smaller number indicates the maximum locking distance for signal reception at the
start of the exercise.
3. The higher number indicates the maximum reception distance during the exercise.
