g. CLMON signal
This signal monitors the CL output voltage. ON (lighted) at HIGH, and
OFF at LOW.
h. CLPR signal
This signal controls the power relay (S701) in the AC input section.
ON at HIGH, and OFF at LOW. When the CL voltage becomes an
overvoltage, the power relay is turned off even through the CLPR is
LOW.
