OPERATION

Do not attempt to operate the Vyper

™

Drive before performing proper setup

the Frick Quantum

™

Lx control panel.

Failure to do so may result in damage to the unit.

QUANTUM

OPERATION – SER-

VICE, FRICK

QUANTUM

™

Lx COMPRESSOR CONTROL

PANEL

” provides detailed information about operation and

settings of the Quantum

™

LX Control Panel.

VYPER

™

OPERATION

Relying on user input as well as system pressures and

temperatures, the Quantum

™

LX directs the Vyper

™

to start

or stop the compressor as well as change the compressor’s

speed to regulate capacity. The setpoints that primarily control

the operation of the Vyper are found on the Quantum

™

LX’s

Capacity Control Setpoints and Motor Setpoints Screens.
When the operator initiates a system start command (lo-

cally or remotely), the Quantum

™

LX sends a signal to the

Vyper

™

to operate the motor. When the Vyper

™

receives

this command, the Vyper

™

begins a precharge process and

prepares to start the motor. During the precharge process

the cooling pump is switched on and the DC link voltage is

slowly increased. After approximately thirty (30) seconds, the

Vyper

™

turns on the motor and ramps up to the speed set by

the VFD “Minimum Drive Output” setpoint. Simultaneously, if

the slide valve is below the Variable Speed Minimum Slide

Valve Position, the Quantum

™

LX immediately loads the slide

valve to the programmed “Variable Speed Minimum Slide

Valve Position” setpoint.
As more capacity is required, the Quantum

™

LX loads the

slide valve. The “Capacity Control” settings (on the Motor

Setpoints Screen) can be configured to cause the motor

speed to increase at the same time, but in most Vyper

™

applications the capacity control “Drive Speed” setpoint is

set to match the “Minimum Drive Output” setpoint. In this

configuration, the motor speed will remain at its minimum

speed until the slide valve loads above the capacity control

“Slide Valve” setpoint. If the slide valve cannot load due to a

slide valve load inhibit condition or because the compressor

cannot build differential pressure, particularly between suc-

tion and oil pressure, the motor speed will increase to meet

the capacity requirement.

When the slide valve reaches the capacity control “Slide

Valve” setpoint, the motor speed can then increase. At this,

point the slide valve and motor speed continue to increase

independently of one another until the capacity requirement

is met or the maximum values are reached. If the compressor

is in “AUTO” mode, the motor speed is controlled by the “VFD

Proportional Band” and “VFD Integration Time” setpoints.
If less capacity is required, the Quantum

™

LX will first de-

crease the motor speed. The motor speed is allowed to

drop as low as the capacity control “Drive Speed” setpoint.

When the motor speed reaches this point, depending on the

Quantum

™

LX’s configuration, the slide valve may unload or

the Quantum

™

LX may stop the compressor. If the slide valve

is permitted to unload, the slide valve will not unload below

the “Variable Speed Minimum Slide Valve Position” setpoint

while the compressor is running.
When the Quantum

™

LX turns off the compressor, the control

panel initially keeps the Vyper

™

in “STANDBY” mode. In this

mode, the drive’s DC Link remains energized so that when

the Quantum

™

LX sends a start command to the Vyper

™

the compressor starts immediately. The Quantum

™

LX panel

holds the Vyper

™

in “STANDBY” mode for up to two (2) hours

after the compressor shuts down. If this standby period

passes without the compressor turning on, the Vyper

™

then

switches from Standby to “OFF”.
When the Vyper

™

enters “OFF” mode, the DC Link is de-en-

ergized and the Vyper

™

will have to go through the thirty (30)

second precharge prior to restarting the compressor. The

current Vyper

™

Operating Mode is displayed on the Vyper

™

Status Screen. To allow the compressor to restart quickly, the

control panel’s Recycle Delay is disabled. When controlled by

the Vyper

™

, the compressor can be started multiple times in a

short period of time without causing damage to the motor.
