Use measurement device
to detect current. Measure current on
the wire from the safety rail and its plug
(a close function).
- if there is current, the safety device
system is working. The lift unit should now
run up/down. REMEMBER to reset.
- if no current can be detected, remove
the plastic covers and slacken the screws
at the end of the safety rail. The rail should
now move freely. Note that the rail's
freedom to move can be hindered by dirt
or grease.
- check for current once more:
If there is current, the safety device
system is working. If no current can be
detected, see under "Faulty switches".
Check whether one or more of the safety
system contacts is sticking, and if so,
attempt repair . If the problem cannot be
fi xed, replace the contact(s). The safety
system will only work when current can be
detected. REMEMBER to reset.
