OTOLIFT 87 - 9.2 PCB LED Status Indicators; 9.3 Error Log Retrieval

20
9.2 LED’s on the PCB
There are 4 LED’s mounted on the PCB.
The 3 LED’s left bellow are mounted for indication of the status of the 375 mA SMD fuse, contact of
overspeed governor (catch) and limitswitch/jumper. (LED 1, 2 & 3)
The LED near the display shows the status of the PCB. (LED 4)
LED 1,2 & 3 on = Fuse 375 mA (F1) safetyline & contact overspeed governor (catch) and limitswitch (limit) OK.
LED 1,2 & 3 off = Fuse 375 mA (F1) safetyline defect / sleepmode / shortcircuit x10-3 to ground.
LED 2 & 3 off = Limitswitch (limit) is operated / jumper as interconnection not connected.
LED 2 off = Contact overspeed governor (catch) is operated.
LED 4 on = OK
LED 4 off = 5A fuse defect/ no battery-voltage
LED 4 flashes = Chairlift is in sleepmode
9.3 Error-log
The PCB stores the errors in its memory.
By using the buttons left and right on the servicebox you can read out the error-log.
Facts & functions of error-log
- Control right => read the stored errors backwards
- Control left => start at latest stored error
- Control left for 10 sec. => delete error-log
- Every 24 hours (when not in sleepmode) the log stores a underscore
- Errors are only stored when the lift is controlled by armrest left/right or remote up/down.
- When the lift has not moved, the same error will stored once.
- When the lift has moved, the same error can be stored more then once.
- Maximum of 20 errors or days can be stored.
- The end of the error-log is shown as a minus
Please note that the underscore is not real time. The system only stores the underscore when the
system has been active for 24 hours.
Example 1
The lift has been active for more then 20 days. (today it is Monday)
A user complains that the lift has stopped several times during movement on Wednesday and Friday.
When the error-log has read out the display could show:
Note that the first error you read is the most recent one.
_ _ _ 2 2 2 _ _ 2 2 2 2_ _ _ _ _ _ _ _ -
or
_ _ 2 2 2 _ _ 2 2 2 2_ _ _ _ _ _ _ _ _-
Display-error 2 means that the swivelseat-switch was operated during operating the lift.
In this case it is obvious that the problem has to be found in the wiring or the adjustment of the switch.
