Figure 5. Lower P.C. Board
D LS-2 Upper Limit 1 — Energizes as signal increases and LED turns on and transistor opens. D LS-3 Lower Limit 2 — Energizes as signal decreases and LED turns on and transistor opens. D LS-4 Upper Limit 2 — Energizes as signal increases and LED turns on and transistor opens. Each limit switch may be configured for (N.O.) or (N.C.) operation. Operation over the entire servo range is available for end of travel or position control. DS-1 through DS-4 are LED indicators located above setpoint potentiometers. The LEDs can assist in determining the state of limit switches. A LED on (red) (Figure 4)indicates the limit switch is open. Potentiometers R9 through R12 control limit switch adjustments LS-1 through LS-4 respectively. Use the limit switch settings to control the maximum and minimum range. Clockwise rotation of the corresponding control potentiometer will cause LS-1 and LS-3 to go off and LS-2 and LS-4 to go on. Counter clockwise rotation reverses this action.
Speed Speed of the actuator can be adjusted with the motor speed potentiometer R57, located on the lower printed circuit board (Figure 5). Once the motor speed potentiometer is set, the current limit potentiometer must be set per the instructions in the Torque Limit section.

Torque Limit Motor torque of the actuator is adjustable to yield an electrical thrust limiting feature. When the motor torque is exceeded, the actuator will stay in place. It can remain in this position indefinitely without overheating provided the current limiting potentiometer is adjusted correctly. Adjustment is via the current limit potentiometer R62 (Figure 5) located on the lower printed circuit board and the procedure is as follows: With the actuator in motion and operated at the selected speed(within the speed-torque range of the device) slowly turn the current limit potentiometer counterclockwise to reduce current limit. Stop turning when the actuator begins to stall due to not enough motor torque. Next give the current limit potentiometer one full turn clockwise. The current limit adjustment is now complete. Any readjustment of the speed potentiometer will require a repeat of this procedure. Figure 6 shows the torque curve of the SM1010 and SM1020 Kixcels.
