The example below shows 1394 (Series A and B) axis modules wired
for thermal fault monitoring. Depending on how the 1394 GMC
system is configured, the fault can be used to disable one or all of the
four axis modules. Two separate 24V DC power supplies and four
relays (CR2-CR5) are included to isolate the THERM FLT inputs
from conducted noise.
