WARNING

DESCRIPTION RECOMMENDED ACTIONS
RecHSnk FbrOptic 170 While Not Running, the Fiber Optic signal
from the TFB on the Rectifier Heatsink,
connected to Channel A fiber optic receiver
RX7 on FOI-L-A is not present. This is only
a fault while not running. If this occurs while
running it will appear as a warning.
RecChB FbrOptic 171 Not Normally Used: While Not Running, the
Fiber Optic signal from the optional TFB
connected to Channel B fiber optic receiver
RX7 on FOI-L-B is not present. This is only
a fault while not running. If this occurs while
running it will appear as a warning.
– Check TFB and FOI board for power
– Check the Fiber Optic cables are properly
seated in the transmitters and receivers
– Check the fiber optic cable for kinks, bends,
breaks that could be blocking the signal
– This can occur if the sensor is not
connected to the TFB
NOTE: This is a warning because the
drive should not fault on the loss of the
signal while running. There is no
imminent danger to the drive, but the
user needs to be aware that there is a
temperature feedback signal missing.
RecHSnk OvrTemp 162 The drive detected that the heat sink
temperature has reached the alarm level.
Ensure that the fan is working properly and
that the air flow is sufficient in this cabinet.
Check TFB & FOI board and sensor. Verify
the trip and warning settings match the
factory recommended values.
RecChB OvrTemp 163 Not Normally Used – The temperature
detection on a Rectifier Heatsink. The drive
has detected that the temperature feedback
from the optional temperature board has
reached the warning level.
– Confirm actual temperature in
parameters is not higher than the
warning value – If so, investigate the
conditions of the drive (ambient / loading
/ elevation / ventilation/ filter status /
heatsink clogging)
– Check TFB and FOI board for power and
fiber optic integrity
– Check the sensor and temperature
offline (ambient) for accuracy
– Ensure that the fan is working properly
and that the air flow is sufficient in this
cabinet.
RecHSnk Sensor 168 While Running, the drive has detected a
missing temperature sensor connected to
the TFB on the rectifier heatsink. A missing
sensor can result in either a Fiber Optic
Loss fault or a Sensor fault because a
missing sensor can be interpreted as either
0°C or over 100°C, and both are unrealistic
values.
RecChB Sensor 169 Not normally used: While Running, the
drive has detected a missing temperature
sensor connected to the optional TFB
connected to the fiber optic receiver RX7 on
FOI-L-B. A missing sensor can result in
either a Fiber Optic Loss fault or a Sensor
fault because a missing sensor can be
interpreted as either 0°C or over 100°C,
and both are unrealistic values.
– Verify sensor is completely seated
properly on TFB.
– Measure sensor resistance. Replace if
necessary.
– NOTE: This is a warning because the
drive should not fault on the loss of the
signal while running. There is no
imminent danger to the drive, but the
user needs to be aware that there is a
temperature feedback signal missing.
