CONNECTION
1) Press the “ON” button
Both ABC and CBA lamps will flash. If the “LOW BATT”
lamp flashes or the rotation lamps do not flash then
replace the battery with a fresh 9V battery.
2) Remove power from the 3-phase power source then
connect the three clip leads.
3) Apply AC power and verify connections.
In proper phase sequence, and with all phases present,
the ABC lamp, and the three line voltage lamps will
illuminate. If the detector indicates all three phases
present, but the CBA lamp is illuminated, disconnect
power and change any two of the three leads. If there is
a loss of one or more phases, both ABC and CBA lamps
will flash. Refer to condition chart on page 1 for more
details. Check for loss of one or more phases and
correct.
4) Remove power and connect corresponding leads to
your equipment after correcting all issues and verify
that the sequence detector indicates all three phases
are present and in the proper ABC sequence.
BATTERY REPLACEMENT
1) Disconnect test leads from power source.
2) Remove the silicone boot on the detector and turn
unit face down in palm or on a clean flat surface.
3) Gently press in at the top of the battery compartment
(located near the bottom of the back side of the unit)
and slide the compartment door towards the bottom of
the unit.
4) Replace old 9V battery with a new 9V battery,
observing polarity.
5) Replace battery compartment door and silicone boot.
