Fault Finding
Before undertaking any detailed Fault Finding, confirm that the basic fault finding in the user
instructions has been undertaken.
Notes on fault finding
1) Before commencing fault finding using the flow chart:-
a) Check the status of all LED’s and fuses – and take any necessary action
b) Check door is closed
c) Ideally the lift should be in mid position i.e. off its limit switches
d) Note that LED’s on the sling board are only illuminated during the “Light on” period
(initiated by up/down/door signal) and when the user LED panel is disconnected.
2) Voltage checks indicate 13.7V this will vary according to battery condition and where it is
being measured – but under no load conditions should never be below 11.8V
3) If the alarm sounds when lift ascending the float switch is closed – detecting a full fluid
catch tank.
