16.1.3 Setting the limit switches
DANGER
Risk of electric shock
▶
Risk of injury or death (if operating
voltage is higher than safe extra low
voltage).
▶
Adjustments are made with the actu-
ator cover removed.
▶
Electric shock can cause severe burns
and fatal injury.
●
Always
disconnect the product from
power supply!
●
Therefore, have all work performed
only by qualified electricians.
CAUTION
Destruction of the actuator!
▶
Do not move the right limit switch too far to the right and
the left limit switch too far to the left, otherwise the actu-
ator will continue running in the end position (i.e. the limit
switch cannot be actuated by the lever and the actuator
continues to run).
