24.6 - Open end-of-stroke indication

'FC' LED blinks when the gate is on an open end-of-stroke area.

24.7 - Close end-of-stroke indication

'FC' LED keeps lit when the gate is on a closed end-of-stroke area.

24.8 - Capacitor load indication

'BUS' LED indicates that the high voltages capacitors are charged. Do not touch them while this LED is ON (even when the control board 

is disconnected from the power supply.

24.9 – Encoder Test

It is possible to test the operator's encoder; to do so; simply connect it to the control board and check if the 'ENCA' and 'ENCB' are 

blinking when the operator runs. Each LED corresponds to a specific sensor; for example, 'ENCA' LED corresponds to the 'A' sensor inside 

the gear motor.

24.10 - Thermal Protection

The operator has a thermal protection device that shuts off the motor when it reaches a temperature above 310 ºF. 

The control board receiving two consecutive commands during this period, it will enter in hardshutdown mode (Audio alarm will 

sound) and the operator will need to be reset. 

For more information see topic  13.5.

25 - MAINTENANCE

On the table below, are cited some PROBLEMS - FAULTS, POSSIBLE CAUSES AND CORRECTION - which may occur in your operator. 

Before any maintenance, the total disconnection from the mains is required.

TROUBLES / SOLUTIONS

FAIL

CAUSE

SOLUTION

The gate does not correspond to the 

path of the place where the operator 

has been installed (It breaks before it 

reaches the stop or slams when closing).

There is an acquired path different from 

the place where the operator has been 

installed.

Press both '+' and '-' buttons at the 

same time and keep them pressed until 

'OSC' LED lits.

Gate keeps open and whenever it 

receives opening commands, it closes.

Acquiring was not properly performed.

Refer to item 'First operation after a 

frequency inverter is installed on the 

operator (Acquiring).

'OSC' LED blinks rapidly and the motor 

turns itself off.

Current sensor activated. This may 

happen when the motor has a 

malfunction.

Check stator resistance. Check the 

motor current (It must be less than 

medium 3A RMS and 5A RMS peak 

current (2s maximum)).
