DIC01, PIC01
Mode of Operation
DIC01 and PIC01 monitor
both AC and DC current and
voltage. DIC01 can also
monitor positive and nega-
tive DC voltage connecting
terminals Y1 and Z3.
Example 1
(no contact input - under+over
voltage - 2 x SPDT N.D. relays
(1 x SPDT for PIC01) - TRMS)
DIC01:
One relay operates
when the voltage drops below
the under voltage set point
for more than the respective
delay time. It releases when
the voltage exceeds the set
level plus the set hysteresis.
The other relay operates
when the voltage exceeds
the over voltage set point for
more than the respective
delay time. It releases when
the voltage drops below the
set level minus hysteresis.
PIC01:
The relay operates
when the voltage drops below
the under voltage set level
for more than the respective
set delay time or when it
exceeds the over voltage set
level for more than the rela-
tive set delay time. The relay
releases when the voltage
exceeds the under voltage
set level plus hysteresis and
