The program has been completed and, in our example, the two relays act like measuring
length limits. In fact, relay 1 closes its contact if the position is lower than 150.00; relay 2,
instead, closes its contact if the position is higher or equal to 300.00.
1.
The activation and the settings of the intervention positions will be
maintained
even after turning-off the instrument.
2.
The MM/INCH conversion does not modify the “real” position of relays
intervention.
Axis in angular reading:
If the instrument is set to operate in angular reading, after having set the intervention
position (in degrees), the instrument requires to enter the angle of the circular sector for
the intervention. The circular sector determines the area in which the relays activate,
according to the formula: intervention angle ± ½ circular sector.
Let us suppose that the operator wants to activate the relay 1 at the position of 90°, with a
circular sector having an angle of 2°.

The program has been completed and relay 1 closes when it enters the circular sector set,
that is, at the position of 90° ± 1°.
1.
The intervention position for the relay has to be between 0° and 359.99°.
2.
The angle of the circular sector has to be between 0° and 180°.
3.
If the operator sets an angle of 0° for the circular sector, the relay intervenes only
if positioned exactly on the intervention position (90° in our example).
