11.0 SM-Basic CONTROL WIRING DIAGRAMS
11.1 TWO-WIRE START/STOP CONTROL
NOTES:
1. Close TB-1 to TB-11 to RUN, and open to STOP. TB-1 functions as a RUN input for two-wire
start/stop circuits, and a STOP input for three-wire start/stop circuits. Refer to Section 11.2.
2. If reverse direction is required, set ROTATION (Parameter 17) to FORWARD AND REVERSE
(02), and program TB-13A (Parameter 10) to RUN REVERSE (05). Close TB-13A to TB-11 to
RUN in the reverse direction, and open to STOP.
3. For speed pot control, set STANDARD SPEED SOURCE (Parameter 05) to SPEED POT (03).

WARNING!
Hazard of electrical shock! The SM-Basic control terminals are not isolated from line voltage!
Line voltage is present between the control terminals and ground. Do not touch!
Disconnect input power and wait three minutes before making connections to the control terminals.
Devices (such as switches, pushbuttons, potentiometers, relays, etc) and wiring connected to the
control terminals are hot to ground and must have an insulation rating of at least 240 Vac or a
dielectric rating of at least 1500 volts to prevent damage to equipment and/or injury to personnel.
