cable entries onto the terminals and fas-
ten them.

If voltage is applied to
eL
, the actua-
tor motor retracts the actuator stem
into the actuator (”Actuator stem re-
tracts“).
4
If voltage is applied to
aL
, the actu-
ator stem is extended (”Actuator
stem extends“).
Actuators operated in parallel must be
controlled using separate contacts as us-
ing one common on/off contact can
cause the actuators to oscillate in the end
positions.
