WHAT IS THE PROBLEM? WHAT CAN BE THE REASON? WHAT CAN BE DONE?
Although the power is supplied,
arms are not locked, indicators do
not light, no operation is
monitored
in the turnstile.
1-Power might not be received.
2-Internal power cable might be
displaced.
3-3 amper glass fuse might be
broken down.
1-Power is supplied to the
turnstile.
2-Power cable is checked out
whether it is plugged or not.
3-3 amper glass fuse is changed.
There is energy but arms are
rotating idle.
1-Locking magnet cables or cables
of photo-cell unit (position
informing) might be displaced.
2-Electronic board might be
broken down.
1-If there is a displaced cable, it
is plugged again.
2-If the electronic board is
broken down, it is replaced with
a new one.
Although there is pass signal
(pass indicator, buzzer) turnstile
does not allow authorisation for
passage.
1-There might be a foreign object
which prevents the operations of
the solenoids of the locking hook
(like a cable).
2-There might be a failure in the
microcontroller on electronic
board or ULN 2803 A circuit that
drives the solenoids.
1-Objects which prevent
operations are moved from the
area.
2-Microcontroller and ULN
2803A circuit or electronic
board is replaced with a new one.
There is no pass signal (pass
indictor, buzzer) but the turnstile
allows authorisation for passage.
1-Pass indicator cable might be
displaced.
2-Microcontroller on the
electronic board or ULN 2803 A
circuit that drives the pass
indicator may be broken down.
1-If there is a displaced cable, it
is plugged again.
2-Microcontroller and ULN
2803A circuit or electronic
board is replaced with a new one.
After passage is done, arms do
not finalise the movement and do
not settle to their place.
1-Balance arm spring might be
displaced or broke off.
2-Hydraulic damper tuning might
be changed.
1-Balance arm spring is replaced
by a new one or plugged again.
2-Hydraulic damper tuning is set
to the sfecified level by means
of tuning capscrews.
After the passage, turnstile is
not being locked and arms rotate
continuously.
1-Spring of locking hook might be
broken off or displaced.
2-Photocell unit might be broken
down.
3-Electronic board might be
broken down.
1-Locking hook is replaced with a
new one.
2-Photocell unit is replaced with
a new one.
3-Electronic board is replaced
with a new one.
During passage, sometimes arms
do not rotate smoothly.
1-Spring of return locking pin
might be broken off that releases
the pin.
1-Spring of return locking pim is
replaced with a new one.
Turnstile does not allow passage
although pass signal is being
received.
1-15'data connector may be
displaced or not being connected
correctly.
2-Commands may not be received.
3-Electronic card may be broken
down.
4-The problem may be related
with the solenoid.
1-2-The connections are checked
out to see whether the
commands are being received or
not.
3-Electronic card is replaced
with a new one.
4-If a malfunctioning is being
recognised at the solenoid, it is
replaced with a new one.
After the finalisation of the
passage, "return" data regarding
with the passage direction is not
seen.
1-Connection ends of the data
connector may not be fixed
correctly or may be broken down.
2-Electronic card may be broken
down.
1-Connections are checked out.
2-Electronic card is replaced
with a new one.
