Alarms During Parallel and Tracking Operation
External alarm 1
If an external alarm 1 occurs during parallel or tracking operation, a buzzer sounds,
an error message is displayed, and all PCZ1000As go to the load-off state.
The alarm message from the protection function is displayed on the PCZ1000A on
which the alarm occurred, and all the other PCZ1000As display:
"*ALARM EXT1*".
When an alarm occurs, the buzzer on the PCZ1000A on which the alarm occurred
sounds at shorter intervals than the other PCZ1000As.
• Turning off the POWER switch on the master unit or any of the slave units when
no alarm is present causes an external alarm 1 to occur on all the other units.
External alarm 2
If an external alarm 2 occurs during parallel or tracking operation, a buzzer sounds,
an error message is displayed, and the PCZ1000A on which the alarm occurred goes
to the load-off state.
The display on the PCZ1000A on which the alarm occurred is:
"*ALARM EXT2*"
• Note that, if the flat cable used to connect PCZ1000As in parallel becomes
disconnected during parallel or tracking operation, the ammeter (rms and peak)
on the master unit will not read correctly.
Clearing alarms
Pressing the SHIFT + ESC (ALM CLR) key clears the alarm, a new alarm will be
generated if the cause of the alarm still exist.
Pressing the SHIFT + ESC (ALM CLR) key on the master unit clears the alarm on
the PCZ1000A other than the one that generated the original alarm.
To clear the alarm on the PCZ1000A where it was generated, press SHIFT + ESC
(ALM CLR) on that unit.

Returning to Standalone Operation
To return to standalone operation after parallel or tracking operation, turn off the
POWER switches on each unit and then unplug the flat cable.
