made on the terminal board of the actuator.
The following options are available:
• 4 wires latched: requires 2 momentary
signals (since the control is self-maintained)
to open or close and one signal to stop in
mid-travel. The action of the stop signal can
be reversed (stop when signal is ON (MAKE)
or stop when signal is OFF (BREAK).
• 3 wires latched instant reverse: requires
2 momentary signals (since the control is
self-maintained) to open or close. Reverse
momentary signal reverses the direction.
• 3 wires momentary: requires 2 push-to-run

maintained) to open or close
• 2 wires open if signal On: requires signal On
to open and no signal to close
• 2 wires open if signal Off: requires signal Off
to open and signal On to close
