22.1 ALARM Indicator (Switch) of OCP Blinks
BS/CCU is equipped with a self diagnosis function to monitor any abnormality in the
BS/CCU itself and the camera. It is activated simultaneously with "ON" of BS/CCU
MAIN POWER switch and is always functioning during operation.
Occurrence of any abnormality in BS/CCU or the camera is detected and ALARM
indicator of OCP starts blinking. The self-diagnosis information display screen is also
displayed on the PM to identify the section of failure.
You can check status with the self-diagnosis information screen displayed on PM by
pressing the PM IND/PAGE switch of OCP even while the ALARM indicator (switch) is
not blinking.
Pressing the switch when the ALARM indicator (switch) blinks enables you to display
simple diagnosis. This enables simplified diagnosis even in a system to which the
BS/CCU is not connected to PM.
Caution
In the BS/CCU, this screen may not display diagnosis even though the PM
displays it. This is not a malfunction since the OCP can not obtain
information due to absence of command compatibility to connected BS/CCU.
