PAS SERIES Parallel and Series Operation 5-9
Remote monitoring
External monitoring of output voltage (V MON)
The output voltage can be monitored only on the master unit.
External monitoring of output current (I MON)
The output current of each master and sla
ve unit can
be monitored.
For the total output current, sum the monitor values of the master and
slave units.
Status monitors
Status of the constant voltage operation (CV STATUS), constant cur-
rent operation (C
C ST
ATUS), OUTPUT ON, and POWER switch ON
can be monitored on each master and slave unit. However, slave units
always output the status of the constant current operation.
For details on ALM STATUS, see the next section, "Alarms".
For details on the remote monitoring, see "4.2 Remote Monitoring".
Alarms
Below is the operation of the units when alarms are activated through
OVP (overvoltage protection), OCP (overcurrent protection), and
OHP (overheat protection).
Slave unit
An alarm is activated independently, and OUTPUT or POWER
swi
tch is tur
ned off.
Master unit
By connecting ALM STATUS of the master unit and SHUT DOWN
o
f th
e slave units as shown in Fig.5-6, the OUTPUT or POWER
switch of the entire system can be turned off when an alarm on the
master unit is activated.
