Part Removal

I posted this on the incorrect class. Below is the original post.

Thank you for allowing me to join this forum.
I am helping a friend whose wife has ALS. He installed a Savaria V1504 that will not operate. I have determined the CEP7 solid state Overload protector is faulty. When pressing the UP button on the controller, the two CA7 contactors energize but the output of the CEP7 is only 26 VAC.

My question is how to remove the CEP7 from the mounting rail.

Thank you,
DanK.

Being your friend is the owner, have you or he contacted Savaria for technical help? They can be pretty helpful over the phone.

Thank you for the reply. That was my next option. I was reluctant since they appear to only work through dealers and authorized repair facilities.
I'll try this this AM.

I contacted Savaria, they directed me to the local Service rep. I called and had a very nice conversation with the owner but he was not very knowledgeable about the technical aspects of the lift. His tech was out on service calls and could not be contacted.

I called the contactor/overload device company, Speckter and Schuh. The technical contact will be out on vacation until 11/27. I'll try then.

Try posting a location. You will be surprised if this is truly to help a friend in need you may be surprised who might help.

We live in North East PA in a small town named Newfoundland..

I think this might be the wrong week to try and get help. I'll wait until after Thanksgiving and to all that are trying to help, Happy Thanksgiving.

Were you able to get a replacement for CEP7? If your only problem is removing it from the rail maybe post a picture here and someone can help you out.

Dan,
Sent you a message. Check your PM box.

I found the problem to be corrosion on the pins of the Overload breaker. This unit was previously install outside. The corrosion prevented the Neutral line from making contact with one of the system.input motor power relays. I did call the tech support at S&S and he sent me a diagram on the mounting method. It took a little extra removal of the contactor to remove the overload breaker. Cleaning the pins with emery cloth and reinstalling solved that problem. I also found the battery charger fuse was blown, and the 24 volt fuse to the hydraulic dump valve had been removed. This was done because the batteries were dead and this fuse circuit supplied 24 volts to all control relays.
Looking at the wiring diagram it had the door close/lock contacts different on two different pages. On one page they were Normally Open and on another page they were Normally Closed. I determined they were Normally Open.

At least now we can proceed to set the upper limits.

Dan K.

DanK,

After your investigating/troubleshooting/repairing the controls, be sure to attempt to run your lift with doors open. Not knowing your abilities electrically, and drawings you’re looking at, be certain you test all safety devices before putting the unit back into service.
