permobile m300 -replacing actuator

[kopernik]

in my wheelchair permobile m300 control board of the footrest drive actuator burned down (water got in).

First, I bought exactly the same board (according to the part number) and replaced it on the actuator. But the drive did not work and the error also blinks on the remote.
Next, I bought a fully footboard actuator (identical to the original one). But even after that, the drive does not work and the error blinks.
I HAVE AN r-net PROGRAMMER. Is it possible for me to turn on the drive and how to do it?

[Burgerman]

No because its permobil. It isnt controlled by the r-net programmer.
You probably burned the ICS thing (permobil).

On almost all other powerchairs, yes you could do that. And it wouldnt need to anyway as they are protected from overcurrent electronically inside the R-Net seating module. Your chair doesnt have an r-net seating actuator module... It uses a home grown permobil one. Which even they dont understand.

Everyone with a permobil accuses me of being negative. Dont blame me, I did not design their systems, or their way of working. All I can do is deliver the bad news. Not my fault.

Try unplugging the CCS thng completely and see if the chair drives normally and no error.

Check the fuse in the master module to be sure it didn't blow when water got into the actuator.
Also, the new actuator control board does not contain the calibration data from the old board. It will need to be calibrated.
Please tell us which type of flashing you are receiving. There are 3 colors, 8 leds, and several patterns that indicate different things.

Red Toggling
When all the Switchbox LEDs toggle red, the ICS system is requesting that the wheelchair be turned
off and back on. This display is given after a new device is connected to the system (plug-n-play)
and after certain programming steps are completed.

(5sec) Brief Red Flashing
The Brief Red Flash indication is a red flash that occurs for 5 seconds, then the switchbox returns to
its previous indication state.
This is the same indication the user gets when an actuator end-of-travel is reached. It also serves as
a Diagnostic indication if the brief red flash is occurring when the actuator is NOT at the end of
travel (maybe the seat function is binding, or maybe the actuator needs to be replaced due to wear.
The Brief Red Flash also occurs when there is a problem with the actuator sensor. If the actuator is
using a softpot, this could indicate the softpot or softpot cable is worn and needs to be replaced.

(always) Constant Red Flashing
The Constant Red Flash always occurs, it never stops.
When an icon on the Switchbox gives a constant red flash this signifies that the seating system
expects that actuator to be connected, but is unable to communicate with it.
This could be caused by a bus communication wire between the actuator and the hub/master module
being damaged.
This can also be caused by incorrect programming (ie. “Recline Installed”, but not connected.)

Vari-Smart Actuator Calibration
If a Vari-Smart Actuator is mishandled before it is installed on the seating system (i.e. the Actuator Screw is manually
moved) then the calibration between the Actuator’s Position Sensor and the actuator ram may have been lost.
It is important that the Screw End of a Vari-Smart Actuator is kept in place with the shipping tape until just before
being bolted to the mounting brackets on the seating system.
However, if the calibration between the sensor built into the Vari-Smart Actuator and the actuator’s length is lost, it is
possible to return the sensor to a known position and manually adjust the ram.
This is accomplished by moving the Seating System’s Vari-Smart Actuators to a known position and then dismounting
the “problem” actuator to adjust its length to the correct value.
Alternatively, this can be done before the actuator is mounted. If it is known that the actuator screw has been moved
manually.
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 on the next page. Screw the actuator ram in or out to match the value on the chart.
8. 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.)
9. Reattach the actuator to the mounting brackets on the seating system.
Repeat steps 6 – 9 for any other “problem” vari-smart actuators.
Note: Actuators with SoftPot Sensors are not calibrated using the process above.
The Soft Pot is a mechanical sensor that does not benefit from this recalibration process. While the actuators with
softpots are moved to a known position during this process, it is not possible to manually adjust the actuator screw end
to correct the calibration – see the section titled Actuator Calibration with Softpot for information about calibrating
these type of actuators.

Actuator Calibration with Softpot
Actuators with SoftPot sensors are not affected by the Actuator Screw being manually moved like Vari-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 Vari-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.

Which even they dont understand.

apparently they do

[Burgerman]

That will be why they take the chair away, and replace huge chunks of it and return it a long time later, and then rinse and repeat when it still got the same problem. And why even their techs have no access to proper programming capability. Thats what has repeatedly been reported here.
