Malfunctions
This section lists some malfunctions that may arise.
ENCODER ALARM
MOTOR OVERLOAD ALARM
MOTOR SHORT CIRCUIT ALARM
LIMIT SWITCH ALARM
PULSE OVERLOAD ALARM
SAFETY EDGE ALARM
After removing the alarm condition, to erase any error message,
simply press "DOWn -" or press the PP button (STEP/STEP)
The display restores the normal signals and the yellow LED turns
off.

The fi rst time that the control unit is powered, a self-learning pro-
cedure must be performed which allows the detection of the basic
parameters such as length and weight of the gate or door and auto-
matically adjusts certain basic parameters

In addition to signals on the display, the fl ashing light signals the
error by a sequence of two short fl ashes pause two short fl ashes
The control unit does not read signals from the encoder
1. The encoder is not connected properly.
2. The encoder is damaged.
3. The motor is locked, and the sensitivity is too low.
4. The motor is disconnected or the connections are damaged.
The absorption of the motor is higher than setting
1. The motor is locked and the control unit tries to unlock it with full power.
2. There is strong friction or an obstacle is blocking the gate.
The motor hardware security is active
1. The motor or the power cables are short circuited.
2. The motor is locked, and the current consumption is higher than the maximum thresh-
old.
The limit switches do not work properly
1. The limit switches are damaged.
2. The limit switches are disconnected.
The motor current has increased very rapidly
1. The gate has hit an obstacle.
2. There is friction on the guide or rack.
The panel has detected a signal from the safey edge
1. The safety edge is pressed.
2. The safety edge is not connected properly.
If the error is MOTOR SHORT CIRCUIT, the PP input has no effect.
If you disconnect the power when errors are displayed, they are
stored by the microprocessor and highlighted again at the next re-
start; to delete them permanently press two times MEnu and then
press one time DOWn.
Pressing + or - you can read the parameters on display (speed,
power consumption, ...) that may be useful to verify that there are
no obstructions or malfunctions of the installation during the travel.
Here below the sequence in which they appear.
