Actuator Calibration with Softpot
Actuators with SoftPot sensors are not affected by the Actuator Screw being manually moved like Smart
Actuators are. It is possible, however, that the SoftPot housing on the actuator is inadvertently moved when
the actuator is being installed.
If the SoftPot housing is not positioned in the correct location, the values that the SoftPot sensor provides
to the ICS Master Module may not represent the actual length of the actuator screw. This can cause the
seating system to recall memory positions incorrectly or move the actuator to an undesired position.
A mis-match between the actual length of the actuator and the length measured by the SoftPot can be
corrected by moving the actuator to a known position and adjusting the position of the SoftPot housing on
the actuator shaft.
The process begins by moving all of the actuators on the seating system to a “known” position. This part
of the process is the same as for Smart Actuators.
To enter the Actuator Calibration mode:
1.
Turn off the wheelchair.
2. The system needs to be started up with a combination of pressed buttons: Press and hold Button 5, 6
and 3 on the ICS Switchbox, while holding these buttons, turn on the wheelchair with the Power Button
on the Joystick (or Input Device).
Once all LEDs on the ICS Switchbox turn green, release Buttons 5, 6 and 3.
• LED #7 and #8 will toggle RED to signify Actuator Calibration mode.
3. To move the Actuators to their calibration positions:
Press and hold Button 5 until LEDs 7 and 8 glow green.
For safety, releasing Button 5 will stop actuator movement. (Continue until LEDs 7 & 8 are Green.)
4. When LEDs 7 & 8 are Green, the sensors inside the actuators have reached a known position. (This
enables the manual re-calibration.)
5.
Turn off the wheelchair.
6. Remove the actuator that is out of calibration from the seating system.
7. Measure the distance between the center of the “Front Hole” and the center of the “Fixed Hole”.
Compare the actuator’s length to the value in the chart on the next page.
8.
Adjust the position of the SoftPot housing according to the following method:
-If the measured value is less than the calibration length shown in the chart, the metal SoftPot housing
must be moved away from the moving end of the actuator.
-If the measured value is more than the calibration length shown in the chart, the metal SoftPot housing
must be moved toward the moving end of the actuator.
9.
Confirm that the hole through the end of the actuator screw/ram is aligned properly with the fixed hole
at the actuator’s other end (the correct position is listed in the chart.)
10.
Reattach the actuator to the mounting brackets on the seating system.
Repeat steps 6 – 10 for any other “problem” actuators with SoftPot sensors.
