Memorization to be carried out of the variation in deceleration
The board recognizes the variation in position of the RALL trimmer
and signals the memorization to be carried out in order to learn the
new deceleration.
Press the PROG key. (see paragraph "RALL trimmer")
saving in progress;
phototest error
Disable phototest (dip-switch 6 OFF), check the operation of the pho-
tocells and their connection;
unknown status, next operation REALIGNMENT;
obstacle for motor 1;
Make sure there are no obstacles across the path of the gate and that
it slides smoothly;
With an active automatic closing feature, after the intervention
meant to detect the obstacle, the automatic closing is deactivated. A
command pulse is required to carry out the closing;
no motor 1 encoder signal;
Check wiring, check encoder by TEST-ENCODER (optional);
no motor 1 signal;
Check wiring, check the motor rotates freely and is powered directly
by the battery, check fuse F5;
max current limit for motor 1 exceeded;
Excessive absorption peaks of the gearmotor, check there are no
obstacles on the automation path, check the current absorption of
the motor when in a no-load condition and when applied to the gate,
master/slave communication error;
Check wiring between the controllers, efficiency of slave controller
(fuses), efficiency of interface boards;
Sensitive edge safety intervention
A command pulse is required to carry out the closure;
