L15 – PIM Over-temp – T908_O Inverter Fault
If the inverter detects an over temperature
condition in the
P
ower
M
odule circuit the inverter
will automatically shut the compressor off and
keep it from operation. The VSODC will leave
the compressor off until the circuit temperature
is reduced to acceptable levels. At this time the
VSOD will restart the compressor. If this fault
occurs 3 times during one call for operation the
VSODC will lock out the compressor to keep it
from continuing to operate for one hour and flash
an ”L” on the dual 7-segment LEDs followed by a
15.
IMPORTANT:
This mode of active
protection must be manually reset.

If the inverter detects an over temperature
condition in the

C
orrection circuit
the inverter will automatically shut the compressor
off and keep it from operation. The VSODC
will leave the compressor off until the circuit
temperature is reduced to acceptable levels. At
this time the VSODC will restart the compressor.
If this fault occurs 3 times during one call for
operation the VSODC will lock out the compressor
to keep it from continuing to operate for one hour
and flash an ”L” on the dual 7-segment LEDs
followed by a 15.
IMPORTANT:
This mode of active
protection must be manually reset.
L15 – Lost Rotor Position - A910_O Inverter
Fault
If the inverter loses the rotor position in the
compressor the inverter will automatically shut the
compressor off and keep it from operation. There
is a 5 minute delay after this fault occurs before
VSODC will restart the compressor. If this fault
occurs 3 times during a single call for operation
the VSODC will lock out the compressor to keep it
from continuing to operate and flash an ”L” on the
dual 7-segment LEDs followed by a 15.
IMPORTANT:
This mode of active
protection must be manually reset.
L15 – Current Imbalance – T911_O Inverter Fault
If the inverter identifies an imbalanced current
draw between the compressor 3 phase windings,
the inverter will automatically shut the compressor
off and keep it from operation. There is a 5 minute
delay after this fault occurs before VSODC will
restart the compressor. If this fault occurs 3 times
during a single call for operation the VSODC will
lock out the compressor to keep it from continuing
to operate and flash an ”L” on the dual 7-segment
LEDs followed by a 15.
IMPORTANT:
This mode of active
protection must be manually reset.
L15 – DC Voltage Low – T914_O Inverter Fault
If the inverter detects an sustained low voltage
condition in the DC bus circuit the inverter will
automatically shut the compressor off and keep
it from operation. The VSODC will immediately
restart the compressor. If this fault occurs 3 times
during one call for operation the VSODC will lock
out the compressor to keep it from continuing to
operate and flash an ”L” on the dual 7-segment
LEDs followed by a 15.
IMPORTANT:
This mode of active
protection must be manually reset.
