procedure does
not complete
correctly.
QR 3+
Motor calibration failed. Repeat acquisition procedure.
If the problem persists, check the cable connecting the
encoder to the motor.

Travel length error.
Move gate into completely closed position (FC limit
switch signal must be active) and repeat the procedure.
Check cable of limit switches. Replace the cable if the
problem persists.
Reset default controller unit parameters and repeat the
procedure.
Stroke length less than the minimum allowed: increase
the length.

Only for BH30/804/R. The gate
is moved by hand without being
unlocked, without mains and/or
battery voltage
WARNING: if B71/BC is used, check the correct con-
nection of the battery charger to the control unit (the
red cable [+] must be connected to the POWER IN ter-
minal 5, the black cable [-] must be connected to the
POWER IN terminal 4). Otherwise, the manual mano-
euvre will not be performed correctly.
The control unit
does not accept
commands.

connection of the POWER-IN
terminal strip.
Reverse the connection of the (+) and (-) wires on the
POWER IN terminal strip of the control unit (see batte-
ry connection at page 2)
By pressing the TEST button, the error can be tempora-
rily hidden to consult the control unit parameters.
N.B.: Press the TEST button to temporarily cancel the alarm.
The next time a command is received, the alarm reappears on the display if the problem has not been resolved.
