CODE
DESCRIPTION RECOMMENDED ACTIONS
Convrtr Air Flow 176 The Pressure drop at the input to the
converter section sensed by the pressure
transducer (as a voltage) has dropped
below the value set in Pressure Value Trip
(P319). This is dependent on the operation
of the Main Cooling Fan.
Verify fan rotation
Check for blocked airflow in the filters/
heatsinks/ ducting (if installed) – Clean as
required
Improper Trip settings – Verify Pressure
Value voltage level when running with
clear air flow, and compare to expected
values for that specific drive type
Check that the pressure sensor is working
and is connected to the ACB at J9.
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 differential
pressure transducer, and confirm output is
stable
ConductivityHigh
(C-Frame Only)
68 The measured coolant conductivity is
greater than 2 μS/cm
3
.
Verify that no foreign debris has entered
the system (iron piping, non-deionized
water, etc.)
Wash the mesh filters
Change the de-ionizing cartridge and run
the system, verifying that the conductivity
is decreasing
Control 5V Loss 54 There has been a loss of the 5 volt DC rail
from the DC/DC Converter.
Check connections, test the rail voltage
level and test for shorts
Replace the DC/DC converter if this
problem remains.
Control 15V Loss 55 There has been a loss of the 15 volt DC rail
from the DC/DC Converter.
Check connections, test the rail voltage
level and test for shorts.
Replace the DC/DC converter if this
problem remains.
Control 56V Loss 52 The drive has detected a loss of the 56V dc
voltage feeding the DC/DC converter.
Check the connections, feedback wiring
on J14 of the ACB, the DC output of the
AC/DC converter and the input voltage to
the DC/DC converter.
Replace the power supply if required.
