Fault 5: Interface Board Panel Communications Loss
Message
Quantum: “Fault 5”
Quantum LX: “VSD Interface Board to Panel Comms Loss”
This fault occurs when the Frick Interface Board loses com-
munications from the Quantum
™
LX Control Panel, meaning
it has not received any data for a period of fi fteen seconds.
It is only applicable in automatic mode.
Fault 7: Vyper Initialization
Message
Quantum: “Fault 7”
Quantum LX: “VSD Initialization Fault”
At power-up, all the boards go through a process called ini-
tialization. At this time, memory locations are cleared, jumper
positions are checked, and serial communications links are
established. There are many causes for an unsuccessful
initialization. The following check list should aid in determining
why the initialization has not been completed:
• The Control Center and the Vyper
™
must be energized at
the same time. The practice of pulling the fuse in the con-
trol center to make wiring changes will create a problem.
Power-up must be done by closing the main disconnect
on the Vyper
™
cabinet with all fuses in place. Be sure you
do not have an open fuse, causing loss of power to the
Vyper
™
Logic board which can cause this fault.
• The EPROMs must be correct for each board, and they
must be correctly installed. There are a total of seven (7)
EPROMs in each Vyper
™
system. These EPROMs are
created as a set, and cannot be intermixed. All pins must
be properly inserted into the EPROM sockets.
• Serial data must be established. (See: Serial Communication
Fault” error code). If communications between the Vyper
™
Logic, Filter Logic, and Interface Boards and Quantum panel
does not take place during initialization, Fault 5 message
will appear before any other message can be generated.
Check to see that the serial communications have been
established by selecting the Motor information screen veri-
fying the drive horsepower. A zero displayed value for this
parameter (and all other Vyper
™
parameters) indicates a
serial communications link or EPROM problem.
• If the Harmonic Filter option is included, make sure the
Harmonic Filter Logic board is not in continuous reset.
This will be evidenced by the LEDs on the fi lter logic
board alternately blinking. To rule out the Harmonic Filter
as the cause of initialization failure, disconnect the fi lter
by switching the fi lter logic board’s SW1 switch to the OFF
position, and removing the 16 wire ribbon cable between
the Harmonic Filter logic and Vyper
™
Logic Board.
Fault 8: Vyper - Stop Contacts
Message
Quantum: “Fault 8 “
Quantum LX: “VSD Stop Contacts Fault “
This fault occurs if the No Fault signal from the Vyper
™
is low.
It indicates a fault is present at the Vyper
™
or the Harmonic
Filter, but the communications data contains no Vyper
™
fault
data for twenty seconds. The Frick Interface Board will send
Initialize data requests while this fault is active.
Whenever the Vyper
™
initiates a fault, it fi rst opens the K1
relay on the Vyper
™
Logic board. When the relay opens,

the voltage between wire #53 and #16 will be 115 VAC. If
wire #53 to #16 circuit ever opens without receiving an ac-
companying cause for the trip over the serial link (within 11
communication tries, approximately 22 seconds), this Fault
Code will be displayed. A loose wire is often the cause of
this problem. Check the #1 to #53 horseshoe jumper in the
Control Center and all other wiring involving #53 and #16.
This fault may be replaced with a Serial Communications
fault if the serial link has failed.
