Limit Switch Setting
WARNING:
Hazardous voltage. Turn off all power and lock
out service panel before installing or modifying
any electrical wiring. Use caution when
energizing inputs.
CAUTION:
Setting limit switches incorrectly may result in
actuator stopping by the mechanical stops.
This may overheat the motor and force it into
thermal overload. Electrical operation will not
be possible until overload resets. The motor
may eventually fail if repeatedly overheated.
The motor control limit switches and auxiliary switches
have independently adjustable cams.
Switch order from top to bottom of the stack:
CLS = Close motor control
ACLS = Auxiliary close
OLS = Open motor control
AOLS = Auxiliary open.
