Hoistway scan has been completed, and sometimes (after the unit has had power off over the whole weekend) when powered up, it will take calls from the cab and hallcall. But both the rear gate and the front gate open very slowly, then go into a normal close sequence.

Then, as you are trying to troubleshoot that, the CS4 fault pops up and shuts you down (critical).

So far the fast tool has said that there is possibly a bad selector micro card, a bad clc board, defective door board, you name it.

Basically what I am asking is if there is anyone north of the border that has run into this problem?

So far the CLC, I/O expansion board, rear door board ,and selector micro card have been swapped out.

Any suggestions would help.

Cheers
