11.3 PRESET SPEEDS (WITH TWO-WIRE START/STOP CONTROL)
NOTES:
1. For preset speed control, all or some of the TB-13 terminals must be programmed as preset speed
selects. If only two or three preset speeds are required, only two of the TB-13 terminals must be
used. Refer to the table in the description of Parameters 31-37 in Section 15.0.
2. Program the PRESET SPEEDS (Parameters 31-37) to the desired values.
3. If speed pot control is desired when none of the preset speeds are selected (all preset speed selects
are open to TB-11), 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.
