JKSSS+ Series - 24

JKSSS+ Series

2.3 - 4.2KV

Positions 5 and 6 accept dry, normally closed contact from the bypass contac-

tor for an At Speed indication. (Factory wired)

Positions 7 and 8 are wired to the coil of the bypass contactor and energizes

and de-energizes the contactor. (Factory wired)

Positions 9 and 10 are wired to the coil of the inline isolation contactor and

energizes and de-energizes the contactor.

Note: All customer contacts are 960VA, 120VAC (Max) rated dry contacts.

LEDs provided on the TCB board (for low voltage testing only):

-12 VDC power supply

+12 VDC power supply

Start = start is initiated to TCB board

Fault = any fault has occurred

Fuse Blown = disconnect open or blown fuse has activated

PFC On = Power Factor Correction Capacitor contacts have energized

Timed Out = Auxiliary time delay contacts have energized

For the following, please refer to Figure 2-6.

Start Delay

This is a selectable delay period between the intiation of the start command and

when the CPU actually receives the start signal. Selecting Jumper X1 or X2 deter-

mines the method by which this delay (in cycles or seconds) is calculated. See SW3

below for instructions on setting the actual delay time.

X1 = (DLY-C) Start time delay in cycles

X2 = (DLY-S) Start time delay in seconds (Factory setting)

Auxiliary (Start) Delay (from the time the start input is given). Selecting jumper X3 or

X4 determines the method by which this delay is calculated (cycles or seconds). See

SW4 below for instructions on setting delay time.

X3 = (AUX-C) Auxiliary time delay in cycles

X4 = (AUX-S) Auxiliary time delay in seconds (Factory setting)

Power Factor Correction (PFC) Capacitor Contactor Delay (From the time the

bypass closes to when contacts change state). Jumper selection determines the

method by which this delay is calculated. See SW5 for instructions.

X5 = (PFC-C) Time delay in cycles

X6 = (PFC-S) Time delay in seconds (Factory setting)

Switch Positions

Please refer to Figure 2-7.

SW1 = ON = Dual Adjustment

OFF = Disabled

SW2* = Not used - Switches SW3, SW4 and SW5 are 7 position dip switches

that use binary code to count up to 127 seconds/cycles (see “Jumper Selec-

tion” above).

SW3 = Start Delay; 7 position dip switch uses binary count up to 127 seconds/

cycles (see jumper selection above). Factory setting: 1 second.

SW4** = Auxiliary (Start) Delay 7 position dip switch uses binary count up to

127 seconds/cycles (see jumper selection above). Factory setting: 1 second.

SW5** = PFC time delay; 7 position dip switch uses binary count up to 127

seconds/cycles (see jumper selection above). Factory setting: 1 second.

Note: This switch interacts with the CPU programming when the Decel function is

enabled

.

Note: These times are in addition to SP2 in the CPU setpoints

Example:

Switch settings are cumulative.

Setting dip switch positions 1, 2,

and 3 to “on” = 1+2+4 = 7 seconds

total time. Note: This example ap-

plies to SW3, SW4 & SW5.
