Red LED

1
Over Temperature Protection
Remove uSTART® from the high temperature condition.
Allow uSTART® to cool. The fault will clear as soon as
uSTART® returns to an internal temperature below 60°C
(149°F)
. If this condition is noted as occurring more than
once on a particular vehicle a reflective heat shield may be
worth installing between a heat source and the uSTART®.
An environmental condition above 65°C
(149°F) will cause uSTART® to enter Fault
Mode in order to protect the product.
Prolonged operation above 65°C (149°F) will
cause reduced lifetime and void the warranty
2
Over Current Protection
The fault condition will clear within 30 seconds and uSTART®
will return to Run Mode. Check for loose electrical
connections and battery condition.
Infrequent activation of Over Current Protection does not
pose any concern for uSTART® and can be expected under
conditions of very high load, or if uSTART® terminals
experience a short circuit (ex. wrench contacts both
terminals during installation).
If fault mode continues to occur after the steps above,
contact Ioxus Customer Service.
High current for extended periods (beyond
normal engine cranking times) will cause
uSTART® to enter fault mode in order to
ensure long term product lifetime is not
reduced.
3
Malfunction Protection
The fault condition will not automatically clear and the RED
LED will remain on. This condition can occur if uSTART®
internal measurements are outside of reasonable values or if
uSTART® detects malfunctions transferring energy. This
could be caused by an internal uSTART® fault or by a poor
electrical connection.
Check for loose electrical connections and battery condition.
Reset power by removing the Negative lead from uSTART®
for 30 seconds and then reattaching. uSTART® will enter
Maintenance mode. Start the vehicle and observe uSTART®
for 1 minute. If the fault persists, contact Ioxus Customer
Service
uSTART® has detected an abnormal internal
condition causing it to enter fault mode.
Red LED
Blink
4
Energy Storage Protection
This condition will clear as soon as ultracapacitor cell voltage
management returns to normal parameters. uSTART® will
reduce ultracapacitor charge voltage maximum limit as long
as the condition persists which will result in less energy
storage, but this will not impact engine cranking
performance.
If the condition persists for more than 24 hours, uSTART®
may enter ERROR Mode.
Abnormality detected with ultracapacitor cell
voltage management.
No LED's

Standby Mode
This is a normal condition. uSTART® will enter Run Mode
automatically when the vehicle is started or a high load is
applied
uSTART® will enter Standby Mode after 1 hour
without vehicle operation in order to conserve
electrical energy.
