12.3 Setting the limit switches
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.
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).
Tools required for setting the limit switches:
Allen key SW3
●
Small Philips head screw driver
●
Always switch the limit switch for signal so that the mo-
●
tor switch is actuated first.
ð Limit switches for signal and motor are already preset.
