Device toControl

Output①Insert the Speed Controller plug into the (Mains)
Power Outlet.

NOTE: Make sure Power Switch is “OFF” and Control
Dial is set to “0” before inserting plug.

②Make sure the Device to control is switched “OFF”;
plug into Output of Speed Controller.
③Turn on Power Switch of Speed Controller.
④Turn Control Dial clockwise to turn on and increase
speed, power level for heaters, or brightness forlighting.
“0” position is off, and “10” position is full power.
Set appropriate power level as required byapplication.

Make sure Power
Switch is “OFF”※Model SP-105 shown.

■If Start Is Not Smooth
If device does not start smoothly, please use thefollowing procedure to adjust start speed.
Turn Control Dial to “0”, and using a ＋ (Phillips) driverin Start Speed Adj. Hole, turn driver left and right toachieve a smooth start.

＋ DriverStart Speed Adj.
(Potentiometer)※Start speed is internal potentiometer soldered to control board- Be careful not to force or turn too strongly.

CAUTION
・Only use within rating. Excessive conditions may
cause malfunction.
・Do not short circuit output. An output short will damage
Controller.
・For use within temperature range of 0°
C〜45°C.
・Controller may cause radio interference. Keep 3m fromreceiving devices to prevent.
・Note - some equipment may cause current surge when
first turned on.
・Electric motors typically require a start current of 1.5〜
1.6× steady state values to achieve rated speed.
Make sure this load current does not exceed rating for
Speed Control model.
・Controller will not control speed for induction typemotors.
※Factory fans are of this type, and for these motors, rotational
speed is determined by load resistance.

・Always start with Control Dial set to zero to prevent
malfunction.
・If Load Current is exceeded on SP-110 model, circuit
breaker will trip. Allow controller to stand for a few
minutes before resetting using Power Switch. Continueuse at a lower current level.
For SP-105 model, please replace fuse.
・For normal operation, motor will not begin to turn, andincandescent bulb will not light when Control Dial is set
to “0” or for very low settings. This is normal behavior.
Output level at position “0” can be adjusted using theStart Speed Adj. control.
・Use only as directed.
