15. MALFUNCTIONS: POSSIBLE CAUSES AND REMEDIES

ERROR ERROR NAME + DESCRIPTION
A5 Obstacle detected.
Obstacle detected during the
opening or closing maneuver
E0 Microcontroller operation
problem.
The working times of the micro-
controller are not correct
E1 Both limit switches pressed
simultaneously
The only non-blocking error.
It happens when both limit
switches are pressed at the same
time; a situation that is impossi-
ble to occur during the correct
operation of the automation.
(DL8 and DL9 off)
E2 Short circuit of the motor
E3 Wrong writing to memory
Problem writing parameters in
memory
By enabling the function, the
flashing light will output a steady
light, without flashing. (yes = ena-
ble/no = disable)
Pay attention to the automatic
reclosing time set after the inter-
vention of the photocells; this value
must always be lower than the
automatic closing time.
The gate only works by keeping the
START key pressed to open and the
PEDESTRIAN key to close
(yes = enable/no = disable)
YES = use in pedestrian input to
connect a sensitive edge
No = use of the pedestrian input to
control the pedestrian opening.
REMEDY
Adjust parameters 9-10-11-12.
If the problem persists, replace the
control panel.
Check the operation of the limit
switches (N.C.).
Check that the motor1 phases are
not short-circuited and that the
power of the motor doesn't exceed
1Kwatt.
Turn off the board and try again. If
the problem occurs again, replace
the board; the memory is damaged.
