unit’s three phases of instantaneous output current
are compared to a prescribed limit, which is con-
tained in the hardware. If the Phase B signal exceeds
the prescribed limit, the fi lter will be inhibited from
operating by inhibiting the Current Regulator Run sig-
nal for fi ve to six input line voltage cycles. If the Phase
B signal exceeds the prescribed threshold three times
in 60 line cycles, the unit will trip and the Quantum™
HD panel will display this message.
Harmonic Filter High Phase C Current Fault – The
unit’s three phases of instantaneous output current
are compared to a prescribed limit, which is con-
tained in the hardware. If the Phase C signal exceeds
the prescribed limit, the fi lter will be inhibited from
operating by inhibiting the Current Regulator Run sig-
nal for fi ve to six input line voltage cycles. If the Phase
C signal exceeds the prescribed threshold three times
in 60 line cycles, the unit will trip and the Quantum™
HD panel will display this message.
Harmonic Filter High Total Demand Distortion –
This shutdown indicates that the fi lter is not operat-
ing correctly or the input current to the Vyper™ /
fi lter system is not sinusoidal. This fault occurs when
any of the three phases of Total Demand Distortion
is greater than 25.0 %, for forty- fi ve continuous sec-
onds while the Vyper™ is running.
Harmonic Filter Input Frequency Out of Range -
The Harmonic Filter monitors the line frequency on its
inputs. If this frequency is out of range, it will cease
fi ltering, and set a bit in the communications packet.
This warning is shown whenever this bit is set.
Harmonic Filter Logic Board Power Supply – This
shutdown indicates that one of the low voltage pow-
er supplies on the Filter Logic board have dropped
below their permissible operating voltage range.
Harmonic Filter Logic Board Or Comms Fault – This
fault occurs if the No Fault signal from the Vyper™ is
low, indicating a fault is present at the Vyper™ or the
Harmonic Filter, but the communications data con-
tains no Harmonic Filter fault data for twenty sec-
onds. The Frick Interface Board will send Initialize
data requests while this fault is active.
Harmonic Filter Low DC Bus Voltage – The DC link
voltage magnitude should remain within -80 VDC of
the bus voltage setpoint determined from the peak
input voltage. If the DC link voltage magnitude falls
outside this range for 100 msec the unit will trip and
the Quantum™ HD panel will display this message.
Harmonic Filter Phase Locked Loop Fault – This
shutdown indicates that a circuit called a “phase
locked loop” on the Filter Logic board has lost syn-
chronization with the incoming power line for a pe-
riod of time.
Harmonic Filter Precharge - High DC Bus Volt – The
DC link voltage will reach at least 500 VDC within 20
seconds after the precharge signal has been asserted
on the 60 Hz VSD and at least 414 VDC within 20
seconds on the 50 Hz VSD. If not, the Quantum™ HD
panel will display this message.
Harmonic Filter Precharge - Low DC Bus Volt – This
fault has two different timing events. First, the DC Bus
voltage must be equal to or greater than 50 VDC for
60 Hz (41 VDC for 50 HZ) 4 seconds after precharge
has begun. Second, the DC Bus voltage must be equal
to or greater than 500 VDC for 60 Hz (414 VDC for 50
HZ) 20 seconds after precharge has begun. The unit
is shut down and this message is generated if any of
these conditions are not met.
Harmonic Filter Run Signal Fault – When a digi-
tal run command is received at the fi lter logic board
from the Vyper™ Logic board, a 1/10 second timer is
begun. A redundant run command must also occur
on the serial data link from the Vyper™ Logic board
before the timer expires. If not, the Vyper™ will be
shut down and this Fault message will be displayed.
Harmonic Filter Serial Communication – When
requesting Status data, the response data from the
Harmonic Filter includes a bit that indicates whether
communications were lost from the Vyper™ to the
Harmonic Filter. If this bit is high for twenty consecu-
tive seconds, this warning is indicated. This warn-
ing is also indicated whenever a receive timeout, or
checksum fault is detected on the Harmonic Filter
communications, for twenty continuous seconds.
Harmonic Filter 110% Input Current Overload – The
overload threshold and timer functions reside in soft-
ware on the Harmonic Filter’s Logic board. The unit’s
three phases of RMS output current are compared to
the overload threshold magnitude. If this threshold
is exceeded for 40 seconds the unit will trip and the
Quantum™ HD panel will display this message.
High Auxiliary Analog 1-20 Shutdown - The Aux-
iliary Analog #1-20 value was greater than or equal
to the high Auxiliary Analog #1-20 shutdown setpoint
for its time delay.
High Auxiliary Analog 1-20 Warning - The Auxiliary
Analog #1-20 value was greater than or equal to the
high Auxiliary Analog #1-20 warning setpoint for its
time delay.
High Auxiliary Analog Input 1-20 Sensor Warning
- This warning message is issued if the sensor con-
nected to the associated Auxiliary Analog Input chan-
nel was above the High End range for its sensor. The
High End range is set by accessing Menu > Calibration
> Auxiliaries > Page 1 or 2, and setting the High end.
This is strictly a warning, as the compressor does not
stop. This warning is logged into the Event Log.
High Bal Piston Pressure Sensor Warning – This
warning message is issued if the Balance Piston Pres-
sure reading (analog board 1, channel 10) was to the
