Problem Found Possible Cause Solutions
Gate opens, but will not close
with transmitter or pause time
different from OFF
a) Open control active
b) Pause not set
c) Close Entrapment Protecting Device active
d) Photocells contact is open
e) Fire-switch input active
a) Check all Open inputs for an active input
b) Check pause settings
c) Check all Entrapment Protection Device inputs for an active
sensor
d) Check photocells contact
e) Check fire-switch input
Gate doesn’t respect slow
down points
a) ENCODER is not working properly if It's
activated
b) Mechanical clutch loose
c) Slow down space is too wide
d) Potentiometer is not working properly if It's
activated
e) The recovery position parameters are too
high or too low
a) Check menu for encoder parameters "Encoder Par" shall be
from a low value +/- 10 (gate completely closed) to "Encoder
tot" (gate completely opened). If the movement of Ipar is not
linear in the range (+/-10 - Encoder tot) probably the Encoder is
defective
b) Tight mechanical clutch
c) Reduce slow down space
d) Check menu for potentiometer parameters "IPar" shall be
from "I. CH."(gate completely closed) to "I.AP." (gate
completely opened). If the movement of Ipar is not linear in the
range (I.AP. - I.CH.) probably the potentiometer is defective
e) Reduce or increase the recovery position parameters
Gate opens suddenly without
start command a) Frequency or other noise from main line
b) Short circuit on the start contact
a) Wiring AC shall be separate from DC wire and pass through
separate conduits. If there is a frequency noise it is possible to
change frequency to another MHz like 868 for example or FM
b) Check all start contacts
Gate doesn’t close in automatic
logic during pause even if a
loop/photo is set as start a) START IN PAUSE is not in ON
b) The photo/loop input is not set as "Delay
pause time"
a) Put in ON the menu of START IN PAUSE
b) Set in the photo/loop menu "Delay pause time"
Gate doesn't have power to
close or reach limit switch
a) Slow down not possible for that site due to
heavy gate or inclination or not new
installation
a) Put Slow Down in OFF
Obstruction in gates path does
not cause gate to stop and
reverse
a) Force adjustment needed
a) Refer to the Adjustment section to conduct the obstruction
test and perform the proper force adjustment that is needed
(sensitivity - torque)
Photoelectric sensor does not
stop or reverse gate
a) Incorrect photoelectric sensor wiring
b) Defective photoelectric sensor
c) Photoelectric sensors installed too far apart
a) Check photoelectric sensor wiring. Retest that obstructing
photoelectric sensor causes moving gate to stop, and may
reverse direction
b) Replace defective photoelectric sensor. Retest that
obstructing photoelectric sensor causes moving gate to stop,
and may reverse direction
c) Move the photoelectric sensors closer together or use edge
sensors instead
Edge Sensor does not stop or
reverse gate a) Incorrect edge sensor wiring
b) Defective edge sensor
a) Check edge sensor wiring. Retest that activating edge sensor
causes moving gate to stop and reverse direction
b) Replace defective edge sensor. Retest that activating edge
sensor causes moving gate to stop and reverse direction
Alarm sounds for 5 minutes or
alarm sounds with a command a) Double entrapment occurred (two
obstructions within a single activation)
a) Check for cause of entrapment (obstruction) detection and
correct. Press the reset button to shut off alarm and reset the
operator.
Shadow loop does not keep
gate at the open limit
a) Vehicle detector setup incorrectly
b) Defective vehicle loop detector
c) Wrong settings
a) Review Shadow loop detector settings. Adjust settings as
needed
b) Replace defective Shadow loop detector
c) Check the photo2 menu is set on shadow loop
Accessories connected to the
accessory power not working
correctly, turning off or
resetting
a) Accessory power protector active
b) Defective control board
a) Disconnect all accessory powered devices and measure
accessory power voltage (should be 23-30 Vdc). If voltage is
correct, connect accessories one at a time, measuring accessory
voltage after every new connection
b) Replace defective control board
