I am assembling this table that we ordered in Feb of 2020, it just arrived at school at the end of the semester. While putting it together it appears that I am missing a circuit board in the electronics box. The relay was just laying in the box when I opened it, and the long red circuit board isn’t there as shown in the assembly instructions online. Can anyone advise? 
that is the location of the Torch Height Control (THC) chip.
if you ordered the table with THC that is where the chip would go.
if you did not order the table with THC…then it is not required and will not hinder the use of the table.
