MP System Changeover
• Automatic Changeover
By detecting the emergency notice (EMA), the system operation changeovers from the MP0
to the MP1 or from the MP1 to the MP0 automatically.
• Manual Changeover
There are two ways for manual changeover as follows.
Case 1 By MB Switch Setting:
Flip the MB switch on the MP0 card to ON (UP position).
- Now changeover is executed.
When you want the stand by MP card to return to the active M P, flip the MB
switch on the stand by MP card to OFF (DOWN position), then flip the MB switch
on the active MP card to ON (UP position).
Case 2 By System Data Setting:
Assign the following data for changeover.
CME0 Y=6>3600: MM DD HH mm
NOTE:
After setting the first data, the MAT indicates "INITIAL?_".
Then input the present time. Now changeover is executed.
When there is no MP card for stand by, or the MB switch on the MP card in stand by is
ON (UP position), the MAT indicates "HARDWARE ERROR".
