Shutdown occurs when the
• Panel screen ON
signal is "L."
(RST4 = H and PSW1 = H)
for 5 sec after PSW1 is ON.
• While awaiting restoration
or
of RST2 (RST2 = L)
for 2 sec while the unit is
ON.
––
Excepting passive standby
Shutdown occurs if the
RELAY2 = ON (High)
signal is "L."
for 5 sec after RELAY2 is
ON.
or
for 2 sec while the unit is
ON or in Functional STB.
Shutdown occurs when the
• RELAY2 = ON
signal is continuously "L"
• Monitor it after 3 sec.
for 30msec * 3 times after

If "RST3 = H" (AC_OFF) is detected under the
monitoring conditions, a power-off process starts.
Monitoring of the RST3 port is continued, and
monitoring of other ports is interrupted.
Communication is controlled only by the IF
microcomputer. The port outputs are set as specified.
If the signal at the RST3 port continues to be H after
30 mS of waiting, monitoring is continued.
If RST3 is L, a restoration process starts according to
the latest power-on/-off status.
Shutdown occurs immediately
