Gate Automation Obstacle Detection – Came Obstacle Detection

Came 24v automation systems use amperometric sensitivity.

Definition: Amperometry in chemistry and biochemistry is detection of ions in a solution based on electric current or changes in electric current.

 

Amperometric sensitivity: the level of gearmotor sensitivity in the face of obstacles during operation.

 

The following information is relative to the ZLJ24 control board which comes in Came kits such as the FerniE and Axo:

When the amperometric sensitivity is on, and an obstacle is engaged, depending on how the configuration is set, the gearmotor works in the following ways:

- timed endpoint: it stops while performing a gate run;

- end point: it inverts direction of travel during operation;

- decelerations: it inverts direction of travel during operation, while during the deceleration phase it stops;

- Fcap-RallCh.: it inverts direction of travel during operation, while during the deceleration phase it only stops when on a closing run.

When the amperometric sensitivity is off, and an obstacle is engaged, the gearmotor stops when the maximum current threshold is exceeded (i.e. overload).

N.B.: this function appears only if the “encoder” function is not selected in the FUNCTIONS menu.
