Polarity Check
After completing the power connection, and before connecting other devices to
the wiring base, be sure to perform a polarity check. When power is applied to
the Axiom wiring base, other devices wired to the Axiom (i.e., tachometer and
photoeye) could be damaged if the power polarity is reversed.
ATTENTION
:
While performing the polarity check, be sure to follow all safety
procedures regarding high-voltage as outlined in
Chapter 2, Safety
. Before
correcting a polarity problem, be sure to disconnect the power source.
IMPORTANT
:
After completing power connections, check Polarity LED inside
the wiring base. A GREEN LED indicates polarity is correct. When more than
one Axiom are daisy-chained together, check polarity in the correct sequence.

1.
Apply power.
2.
Check that all Polarity LEDs are
GREEN
. If multiple Axiom are daisy-
chained together, check the polarity of the first unit in the chain (i.e., unit
wired directly to power source), then the second, then the third. If all
Polarity LEDs are
GREEN
, polarity is correct.
3.
If any Polarity LEDs are
RED
, polarity is reversed and must be corrected.
4.
Disconnect from power source.
5.
Correct wiring. For single units, simply swap the wiring at the INPUT
POWER terminal block of any unit that had a
RED
polarity indication. In a
daisy-chain, correct the wiring on the first unit in the daisy-chain that had
a
RED
polarity indication.
6.
Reconnect to power source.
7.
Apply power.
8.
Check polarity to assure wiring has been corrected.
9.
If all Polarity LEDs are
GREEN
, polarity check is complete.
USEFUL TIP
: In daisy-chained power applications, if the first or second unit’s
Polarity LED is
RED
and the last unit‘s LED is
GREEN
, you need to swap the
INPUT POWER wiring of the first unit with
RED
LED and the OUTPUT POWER
wiring of the last unit with
RED
LED.
