 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.
