SlideTrack - Operation abnormalities
Abnormality:
operates intermittently
Cause:
the copper belt is not flat – the brush
‘skips’.
Solution:
flatten or replace the copper belt on the
communication contact electrode.
Cause:
the communication line is dirty / cannot
transfer.
Solution:
clean/polish the communication belt.
Cause:
very bad ground connection between the
MS125 and 126EL printed circuits.
Solution:
check that the copper earth connection of
the power supply block is good for the com-
plete course of the stairlift (visual downhill
course).
Abnormality: the stairlift stops and shows no
messages. The stairlift doesn’t start.
Cause:
thermal fuse overheated.
Solution:
turn the stairlift off for 30 seconds, then
turn it on again.
Cause:
short circuit on the communication circuit.
Solution:
locate the short circuit between the track
and the communication.
Abnormality: the stairlift turns off when it is loa-
ded on the track.
Cause:
short circuit from the communication brush
to the track.
Solution:
use an isolated brush loading tool.
Abnormality: the power supply connection
doesn’t work.
Cause:
an incorrect upper limit switch was placed
on the SlideTrack.
Solution:
adjust the position of the limit switch as
shown below.
Adjusting the upper limit switch
- The power supply hinge must receive a signal from
the microswitch inside the track in order to function.
Then the switch must be moved upwards, to the ma-
gnet inside the pierced laminated section (blocked by
an M6 hex screw located below on the fixing foot).
- The centre of the microswitch must be approx. 20
mm from the from the magnet.
- There is a hole which the microswitch refers to. Such
reference distance can be changed by pressing inside
the hole to decrease the hold and then slide the mi-
croswitch all the way down into the channel in order to
capture the signal in the best way.
