Control Wiring Terminal Blocks
CAUTION
Only apply 24 Vdc to Control Power Terminal Block. All
control wiring is 22–12 AWG (0.33–2.5 mm
2
).
CAUTION
Do not apply 120 Vac to Control Power Terminal Block.
Do not apply 24 Vdc to Network communications Terminal
Block.

S801+ Control Terminal Block Wiring
Control Terminal Block—Descriptions
The S801+ Soft Starter has the following control terminal block control input and
aux relay functions:
Terminal Block Functions
“–“ and “+” Control Power—Connect power supply
negative to pin “–” and to system ground. Connect +24 Vdc
output to pin “+”. Verify that the 24 Vdc control power
source has the recommended capacity. Minimum control
voltage is 18 Vdc.
Note: To avoid voltage drop during bypass contactor inrush,
a minimum of 14 AWG (2.5 mm
2
) wire should be
used between the power supply and the “+” and “–”
inputs at the S801+ terminal block.
P-Permissive—Control Input 24 Vdc only (maintained).
Permissive must be energized (+24 Vdc) to enable START or
RUN operation of the unit from any source. If power is
removed from the permissive circuit at any time, the unit will
begin a STOP command. If a soft stop is selected, the soft
stop will begin and run to time-out.
1–START—Control Input 24 Vdc only (momentary input with
3 wire control, maintained for 2 wire control). Applying 24 Vdc
to terminal 1 while P is energized will initiate a START
command. As shipped from the factory this input is “level”
sensitive.
2–JOG—Control Input 24 Vdc only (momentary). Input 2 is
JOG. Applying 24 Vdc to this input while P is energized will
initiate a JOG. JOG will follow the selected ramp profile as
long as the signal remains present. The unit will not close the
internal bypass contactors.
3–Disable OL on Strt—Momentary application of +24 Vdc to
Terminal 3 prior to a start raises the overload fault trip point
to 125% of the maximum rating of the frame size for the
next start only.
4–RESET—Fault RESET Control Input 24 Vdc only
(momentary). Input 4 is Fault RESET. Energizing this input
will reset a fault only if no active faults are present.
