Troubleshooting
The
platform is open and in or near a landing station and does not react at all
If unit is near to a landing station use the hand wheel and move platform away from
landing station so the lock barrier arm levers and the charging lever are both not
pressed. If the lift then runs again check barrier cams position.
If the unit is in the landing station, check the ultimate limit switch located under the
carriage covers (which also activate the limit switch). If they are pressed drive back
with the use of the hand wheel and prove the function of the limit switch
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.
Check if LED 24 is on. If not check barrier arm safety switches S14 and S15 and
the ultimate limit switches S22u and S22o
The
platform can open and close in landing station and can run with the platform
open but can not run with the platform closed
Check adjustment of switch S11o. This switch must be pressed when the platform
is closed. If not pressed LED 12 is off.
