Description
Option
Type
K1
Door-Mounted Speed Potentiometer
— Provides the SVX9000 with the ability to adjust the frequency reference using a door-
mounted potentiometer. This option uses the 10V DC reference to generate a 0 – 10V signal at the analog voltage input signal
terminal. When the HOA bypass option is added, the speed is controlled when the HOA switch is in the hand position. Without
the HOA bypass option, a 2-position switch (labeled local/remote) is provided on the keypad to select speed reference from the Speed
Potentiometer or a remote speed signal.
Control
K2
Door-Mounted Speed Potentiometer with HOA Selector Switch
— Provides the SVX9000 with the ability to start/stop and adjust
the speed reference from door-mounted control devices or remotely from customer supplied inputs. In HAND position, the drive
will start and the speed is controlled by the door-mounted speed potentiometer. The drive will be disabled in the OFF position.
When AUTO is selected, the drive run and speed control commands are via user-supplied dry contact and 4 – 20 mA signal.
Control
K3
3 – 15 psig Follower
— Provides a pneumatic transducer which converts a 3 – 15 psig pneumatic signal to either 0 – 8V DC or a
1 – 9V DC signal interface with the SVX9000. The circuit board is mounted on the inside of the front enclosure panel and con-
nects to the user’s pneumatic control system via 6 ft. (1.8m) of flexible tubing and a 1/4 inch (6.4 mm) brass tube union.
Control
K4
HAND/OFF/AUTO Switch for Non-bypass Configurations
— Provides a three-position selector switch that allows the user to
select either a Hand or Auto mode of operation. Hand mode is defaulted to keypad operation, and Auto mode is defaulted to
control from an external terminal source. These modes of operation can be configured via programming to allow for alternate
combinations of start and speed sources. Start and speed sources include Keypad, I/O and FieldBus.
Control
K5
MANUAL/AUTO Speed Reference Switch
— Provides a door-mounted selector switch for Manual/Auto speed reference.
Control
K6
START/STOP Pushbuttons
— Provides door-mounted START and STOP pushbuttons for either bypass or non-bypass
configurations.
Control
KB
115V Control Transformer – 550 VA
— Provides a fused control power transformer with additional 550 VA at 115V for customer use. Control
KF
Bypass Test Switch for RB and RA
— Allows the user to energize the AF drive for testing while operating the motor on the
bypass controller. The Test Switch is mounted on the inside of the enclosure door.
Addl. Bypass
KO
Standard Elapsed Time Meter
— Provides a door-mounted elapsed run time meter.
Control
L1
Power On and Fault Pilot Lights
— Provides a white power on light that indicates power to the enclosed cabinet and a red fault
light indicates a drive fault has occurred.
Light
L2
Bypass Pilot Lights for RB, RA Bypass Options
— A green light indicates when the motor is running in inverter mode and an
amber light indicates when the motor is running in bypass mode. The lights are mounted on the enclosure door, above the
switches.

LA
Green RUN Light (22 mm)
— Provides a green run light that indicates the drive is running.
Light
LD
Green STOP Light (22 mm)
— Provides a green stop light that indicates the drive is stopped.
Light
LE
Red Run Pilot Light (22 mm)
— Provides a red run pilot light that indicates the drive is running.
Light
LF
Red STOP Light (22 mm)
— Provides a red stop light that indicates the drive is stopped.

LJ
White Power On Light (22 mm)
— The 22 mm white light that illuminates when the drive assembly is powered.

LU
Misc. Light (22 mm)
— Provides a misc. “user defined” pilot light. User to define light function and color.

P1
Input Disconnect Assembly Rated to 100 kAIC
— High Interrupting Motor Circuit Protector (HMCP) that provides a means of
short circuit protection for the power cables between it and the SVX9000, and protection from high-level ground faults on the
power cable. Allows a convenient means of disconnecting the SVX9000 from the line and the operating mechanism can be padlocked
in the OFF position. This is factory mounted in the enclosure.
Input
P2
Disconnect Switch
— Disconnect switch option is applicable only with NEMA Type 1 and NEMA Type 12 Freestanding drives.
Allows a convenient means of disconnecting the SVX9000 from the line, and the operating mechanism can be padlocked in the
OFF position. This is factory-mounted in the enclosure.
Input
P3
Input Line Fuses Rated to 200 kAIC
— Provides high-level fault protection of the SVX9000 input power circuit from the load side
of the fuses to the input side of the power transistors. This option consists of three 200 kA fuses, which are factory mounted in
the enclosure.
Input
P7
MOV Surge Suppressor
— Provides a Metal Oxide Varistor (MOV) connected to the line side terminals and is designed to clip
line side transients.
Input
PE
Output Contactor
— Provides a means for positive disconnection of the drive output from the motor terminals. The contactor
coil is controlled by the drive’s run or permissive logic. NC and NO auxiliary contacts rated at 10A, 600V AC are provided for cus-
tomer use. Bypass Options
RB
and
RA
include an Output Contactor as standard. This option includes a low VA 115V AC fused
Control Power Transformer and is factory mounted in the enclosure.
Output
PF
Output Filter
— Used to reduce the transient voltage (DV/DT) at the motor terminals. The Output Filter is recommended for cable
lengths exceeding 100 ft. (30m) with a drive of 3 hp and above, for cable lengths of 33 ft. (10m) with a drive of 2 hp and below, or
for a drive rated at 525 – 690V. This option is mounted in the enclosure, and may be used in conjunction with a Brake Chopper Circuit.
Output
PG
MotoRx (300 – 600 Ft.) 1000 V/μS DV/DT Filter
— Used to reduce transient voltage (DV/DT) and peak voltages at the motor
terminals. This option is comprised of a .5% line reactor, followed by capacitive filtering and an energy recovery/clamping circuit.
Unlike the Output Filter (See option
PF
), the MotoRx recovers most of the energy from the voltage peaks, resulting in a lower volt-
age drop to the motor, and therefore conserving power. This option is used when the distance between a single motor and the
drive is 300 – 600 feet (91 – 183m).
This option can not be used with the Brake Chopper Circuit. The Output Filter (option
PF
)
should be investigated as an alternative.
Output
PH
Single Overload Relay
— Uses a bimetallic overload relay to provide additional overload current protection to the motor on con-
figurations without bypass options. It is included with the Bypass Configurations for overload current protection in the bypass
mode. The Overload Relay is mounted within the enclosure, and is manually resettable. Heater pack included.
