The below schematic works for M400 & M800 actuators. The system needs a 30VA transformer for the new actuator. The actuator dipswitches need to be adjusted for Floating [24v open & 24v close] dipswitches 1 & 2 on and the rest off.
Manual Operation
There is a red manual operation handle on the actuator, see figure 2. When it is lowered, the motor stops. Then the actuator can be operated manually if the handle is turned.

New Wiring
ATTENTION: Actuators are shipped with manual override lowered (MAN). For normal operating, the handle must be raised (AUTO).
