SECTION 6 SUPERVISOR CONTROLLER™ USER MANUAL
39
6 Emergency stop An Emergency stop signal was
received from one of the digital
inputs Determine the reason for the Emer-
gency stop and remedy it.
7 Saturation trip • defective component
• motor or motor cable short Cannot be reset from the keypad.
Switch off power. If this fault
appears simultaneously with Fault
1, check the motor and motor
cables.
IF THE PROBLEM IS NOT IN THE
MOTOR OR ITS CABLES, DO
NOT RE-CONNECT POWER!
Contact Sullair service.
8 System fault • component failure
• faulty operation
Note: exceptional fault data
record, see the Active Fault Menu
and Fault Time Data Record for
more information Reset the fault and restart. Should
the fault reoccur, contact Sullair
service.
9 Undervoltage DC-link voltage is less than the
minimum safe operating voltage
limit.
• most probable cause: too low a
supply voltage
• variable speed drive internal
fault If there was a supply voltage loss or
dip, reset the fault and restart the
variable speed drive.
Check the supply voltage. If it was
within specification at the time of
the fault, an internal failure has
occurred. Contact Sullair service.
10 Input line
supervision Input line phase is low or missing. Check the utility supply voltage,
cables and connections.
11 Output line
supervision Current sensing indicates that
there is no current in one motor
phase. Check the motor cables, connec-
tions and motor.
13 Undertemperature Heatsink temperature is under
14°F(-10°C) Provide supplemental heating or
relocate the variable speed drive to
a warmer location.
14 Over-temperature Heatsink temperature is over
194°F(90°C). An overtemperature warning is
issued when the heat sink tempera-
ture exceeds 185°F (85°C), a fault
occurs at 194°F (90°C). Check for
the correct amount and unrestricted
flow of cooling air.
Check the heatsink for dust or dirt
buildup. Check the highest ambient
temperature level. Make sure that
the switching frequency is not set
too high in relation to ambient tem-
perature and motor load.
15 Motor stalled • motor or load mechanical failure
• load is too high
• stall parameter settings incorrect Check motor, mechanical system
and load level.
Confirm the stall parameter settings
