With your 104 E Reversing unit, positioning the switch in the PROG position locks your engine
into its last moving direction plus neutral. Positioning the switch in the RUN position resumes
normal sequencing operation.
Summary Table of Engine Directions
Condition
Case #1: First power up, or without power longer than 5 sec.
E unit off (switch in PROG position)
E unit on (switch in RUN position)
Case #2: Engine without power for less than 2.5 seconds
E unit off (switch in PROG position)
E unit on (switch in RUN position)
NOTE: Due to limitations of the electronic components, it is hard to predict how each engine
will function when power is interrupted between 2.5 seconds and 5 seconds. Engines will func-
tion either as in case #1 or case #2. This solely depends on the tolerances of the installed elec-
tronics and is not affected or caused by your power supply.
