inhibiting the Current Regulator Run signal for five 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
message.
Harmonic Filter High Total Demand Distortion –
shutdown indicates that the filter is not operating
correctly or the input current to the Vyper™ / filter system
is not sinusoidal. This fault occurs when any of the three
phases of Total Demand Distortion is greater than 25.0 %,
for forty-five continuous seconds 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 filtering, 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 power supplies on
the Filter Logic board have dropped below their
permissible operating voltage range.
Harmonic Filter Logic Board Or Comms 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 contains no
Harmonic Filter fault data for twenty seconds. 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
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 synchronization with the
incoming power line for a period 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
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 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
™
bit is high for twenty consecutive seconds, this warning is
indicated. This warning 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 software 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
display this message.
High Auxiliary Analog 1-20 Shutdown - The Auxiliary
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 connected to the
associated Auxiliary Analog Input channel 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 Pressure reading
(analog board 1, channel 10) was to the upper or
maximum range (out of range) for its sensor.
High Comp. Oil Pressure Sensor Fault - This shutdown
message is issued if the Oil Pressure reading (analog
board 1, channel 6) was to the upper or maximum range
(out of range) for its sensor.
High Comp. Oil Pressure Shutdown – The Oil Pressure
was greater than or equal to
Shutdown
setpoint for its time delay.
High Comp. Oil Temperature Shutdown - The Oil
Temperature was greater than or equal to
Temperature Shutdown
setpoint for its time delay. To
access this setpoint: Menu > Setpoints > Package.
