
FAULT LED
ON
High Battery Temp Fault - The PT controller turned off because the temperature
around the BTS has reached a temperature greater than 54°C/129°F.
Remedy: Check the area where the BTS is located; if placed on a battery,
ensure the connection to the battery terminal is tight, that the batteries are
not overheated, or that the BTS hasn’t been placed in a hot area or near
a hot device. If neither of these are the issue, then remove the BTS from
the BTS port. If the fault clears, replace the BTS. If the fault continues, then
inspect the BTS port for cleanliness and/or have the controller serviced.
This fault will automatically clear and the controller will resume operation
when the BTS temperature has cooled down below 50°C/122°F. This fault
can also be cleared manually by pressing the RESET pushbutton for one second
when the BTS temperature falls below 54°C/129°F.
Info: The digital display alternates this fault code (F07) with the BTS
temperature.

FAULT LED
ON
Internal Overload Fault - The PT controller turned off to help protect itself because
the current to an internal sensor has exceeded the controller’s protection limits.
Remedy: Press the RESET pushbutton for one second which should clear
the fault and turn the controller on. If fault cannot be cleared, there may be
damaged/faulty components inside the controller and it will require repair.

FAULT LED
ON
Internal Phase Fault - The PT controller turned off to help protect itself because
one or more of the internal phases is faulty, or the phase signals are not in sync
with each other.
Remedy: Press the RESET pushbutton for one second which should clear
the fault and turn the controller on. If fault cannot be cleared, there may be
damaged/faulty components inside the controller and it will require repair.

FAULT LED
BLINKING
BTS Open Fault - The PT controller continues to run, but blinks the fault light
to indicate that the BTS is no longer connected, and temperature compensated
charging is no longer available. Normally when a BTS is connected, it communicates
temperature information to the controller. This fault occurs when the controller
is no longer receiving this information. This can occur if the BTS falls out or is
disconnected or damaged.
Remedy: The fault will automatically clear once a good BTS is reconnected.
If the BTS is determined to be faulty, this fault can be cleared manually
by removing the faulty BTS and pressing the RESET pushbutton for one
second.

FAULT LED
ON
Internal Power Fault - The PT controller turned off to help protect itself because
the internal power control circuitry reached its protection limits.
Remedy: Press the RESET pushbutton for one second which should clear
the fault and turn the controller on. If fault cannot be cleared, there may be
damaged/faulty components inside the controller and it will require repair.
