IsoTx AirFlow
(A-Frame Only)
205 The Pressure sensed by the pressure
transducer in the integral Isolation
Transformer section (as a voltage) has
dropped below the value set in Pressure
Value Transformer Warning (P653).
– Verify fan rotation
– Blocked airflow in the filters / ducting (if
installed) – Clean as required
– Improper Warning settings – Verify
Pressure Value voltage level when
running with clear air flow
– Verify Alarm and Trip set-up procedure
was completed adequately and adjust as
necessary
– Verify for drives with external ducting that
there is sufficient air to the drive input
– Verify supply voltage to pressure
transducer, and confirm output is stable
– Ensure pressure sensor is working and is
connected to the ACB
IxoTx Fans On 207 Isolation Transformer Fan ON warning
This warning is for drives with Redundant
isolation transformer fan option. The drive
detected the loss of Fan 2 and starts Fan 1.
Investigate Fan 2 loss and verify Fan 1
operation. Reset warning at next shutdown
and Fan 2 will start running
– Isolation transformer Fan status is high
while it should be low.
– Investigate the control circuit for isolation
transformer Fan
– Check the wiring at XIO for fan status.
L Input Low 64 Indicates that the Autotune L Input (P217)
measured was less than 0.02 pu and the
INPUT IMPEDANCE (P140) will have to be
tuned manually.
For PWM rectifier drives, verify that the line
reactor is properly installed.
L Input High 65 Indicates that the Autotune L Input (P217)
measured was greater than 0.50 pu and the
INPUT IMPEDANCE (P140) will have to be
tuned manually. For PWM rectifier drives,
verify that the size of line reactor is correct.

InpCtctrFeedback 159 The drive has detected the presence of
medium voltage but is not sensing the input
contactor status. Check the contactor
feedback wiring to the ACB.
– Verify the contactor is closed
– Confirm the feedback path from the
contactor to the XIO
– Replace XIO if required
