7i96 estop loop problem

This is my first time using the MESA 7i96 board.  The estop button and screen controls seem to work ok but I am not getting a change on pin 14 with 24 volts on pin 13.
What did I do wrong?

If you have +24V on Pin 13 you have the output polarity of SSR0 backwards

OUT+ goes to the positive voltage source

I moved the wires but the output is active all the time. What did I miss?

Is the LED for SSR0 on?

yes

I guess I would trace these signals
(the first token after net) with halshow,
starting with estop-out

net estop-loopout iocontrol.0.emc-enable-in <= estop-latch.0.ok-out
net estop-loopin <= iocontrol.0.user-enable-out => estop-latch.0.ok-in
net estop-reset iocontrol.0.user-request-enable => estop-latch.0.reset
net remote-estop estop-latch.0.fault-in <= hm2_7i96.0.gpio.010.in_not
net estop-out <= estop-latch.0.fault-out

How can I invert ssr.00.out.00 as I need to have it active when out of estop.

I would wire it to estop-latch.N.ok-out

I changed net estop-out <= estop-latch.0.fault-out to estop-out <= estop-latch.0.ok-out and now I get an error that estop-latch.0.ok-out is already connected to estop-loopout

Can you send me to the appropriate place in the manual so I can understand how this works?
Thanks for your patients

Then instead change

net estop-out => [HMOT](CARD0).ssr.00.out-00

to

net estop-loopout => [HMOT](CARD0).ssr.00.out-00


There is the manual page for estop_latch, io and iov2 but there does
not seem to be a LinuxCNC guide to setting up Estop.

Skunkworks video is a nice introduction however:
