INTERNAL: MF-63103, MF-63123 to M400, or M800 Wiring Instructions (Airflow)




 
INTERNAL
Issue:
How to wire an actuator for an Airflow unit.

Product Line:
All Airflow units.

Environment:
All Serial Numbers

Cause:
Install/Repair

Resolution:

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.

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