State of Outputs During PWR. Fail = Disables when 24 VAC PWR drops below 18 VAC
State of Outputs After PAR. is Restored = Remain disabled for 10 seconds minimum, and then come on per
Restart Configuration.
* NM = normal mode, CM = common mode.
CM Cap is a common mode capacitor connected from the I/O point to a separate ground plane.
** To interface to TTL outputs such as demand meters, use an open collector output to drive the +15 VDC pull-up resistor and
contact cleaning current capacitor.
