SHUTTER ACTION
Alarm output condition
This alarm is issued if, after the LRDY state is established in the
sequence, the shutter open command does not match the shutter state.
When the shutter open signal SHOP is "1", the system is considered
normal with the shutter state signals SHON=1 and SHOF=0.
When the shutter open signal SHOP is "0", the system is considered
normal if the shutter state signals SHON=0 and SHOF=1.
Otherwise, the alarm is issued. When SHOP changes, however, the
alarm monitor is masked for the time set in parameter No. 15152
(default: 3 seconds).

DISCHARGING
After the discharge start (HV ON) signal is turned on, the
discharge starts. At this time, this alarm is issued if at least one
discharge tube does not discharge and causes high voltage.
Alarm output condition
When the HVON signal is turned on, the discharge tubes are started up
to the maximum specified with the bias command in six seconds. Then,
after the time set with parameter No.15222 has elapsed, the voltage of
each discharge tube is compared with the setting of parameter
No.15221. This alarm is issued if the voltage of at least one discharge
tube exceeds the setting of the parameter.
