: Underwriters Laboratories requires a
fan interlock circuit to insure the blower
remains operating whenever more than one
sequencer is used.
The fan interlock should
be the M1/ M2
contacts of the second or third sequencer.
All M1/ M2
contacts are wired to the blower
motor so that any sequencer that is energized
will keep the blower ON.
