2.10.1 JKSSS Plus-TCB Board
The JKSSS Plus-TCB board provides
interconnections between the main power and
CPU boards and the customer’s control logic
connections. It is a 120Vac control board with
several auxiliary dry control contacts, built-in
time delay circuits and emergency bypass func-
tions. It also controls the sequence of the inline
isolation and bypass contactor and provides
provisions for shutdown interlocks. (see section
2.10.2)

Start/Stop Control - Terminal Block 1 (TB1) :
•
Positions 1 and 9 are the 120 Vac control power.

Positions 2-3 and 4-5 are factory jumpers
installed and can be removed for customer’s
normally closed, dry, shutdown contacts (See
