2.10.1JKSSSPlus-TCBBoard
The JKSSSPlus-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. (seesection

• 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
Fig. 2-1 above).
• Positions 6-7-8 are for either two wire or three-
wire start/stop logic. Two wire is connected to
positions 6 and 8 with a N.O. dry, maintained
start/stop contact. Three wire control connects
to 6 with 7 as the stop push-button, and the start
push-button is connected to 7 and 8.
• Positions 10-11-12 is a dry FORM C contact.
The contact is an immediate start/stop contact.
