platform lift
page 22 of 24
The
platform is closed and does not react at all
First use the hand wheel to wind it around 10cm upwards. If the unit is in the upper landing
station wind it 10cm downwards with the hand wheel. Then try function again.
If the unit still does not work open the platform manually by disconnecting the platform
connection. Take off side wall plastic covers and check LEDs on the switchboard and
position of switches.
Check if LED 24 is on. If not check barrier arm safety switches S14 and S15 and
the ultimate limit switches S22u and S22o
When a button is pressed on the remote sender and there is no red LED activated
on the switchboard then check the programming of the remotes.
If the unit is in the landing station, check the ultimate limit switched located under
the carriage covers that also activate the limit switch. If they are pressed drive back
with the use of the hand wheel and try again
If the platform is in a landing station check if the opposite limit switch is not pressed.
If the upper limit switch S27 is pressed then LED 25 is off. If the lower limit switch
S28 is pressed then LED 26 is off.
If the platform still does not move at all
check the battery voltage
. It should be 12-13V
while pressing a drive button. If voltage is too low please check if the output voltage of the
charger is around 24V DC. Please disconnect the charger from the charging stations when
you measure. If the voltage it not around 24V then the charger is damaged.
If the platform
folding movement stops
or works only incrementally then please check
the potentiometer R50 as described below.
If the
driving up of the platform along the rail stops
or only works incrementally then
please check the potentiometer R40
If the
platform stopped around 20-30cm after driving out of a landings station
then
please check if the barrier arm safety switches S13 and S14 are free.
