Power ON delay 1 ± 0.5 s
Power ON delay 6 ± 0.5 s
5
Contact input as latch func-
tion enable. When the contact
is closed the latch function is
activated. The reset of the latch
condition occurs when the con-
tact is open or by power down.
Contact input as inhibit of
alarm enable. When the con-
tact is closed the relay remains
in normal position even if the
alarm condition occurs.

Set point 1 over voltage/-
current monitoring relay. The
alarm condition occurs when
voltage/current input is over the
set point value.
Set point 1 under voltage/-
current monitoring relay. The
alarm condition occurs when
voltage/current input is under
the set point value.

Set point 2 over voltage/-
current monitoring relay. The
alarm condition occurs when
voltage/current input is over the
set point value.
Set point 2 under voltage/-
current monitoring relay. The
alarm condition occurs when
voltage/current input is under
the set point value.

Selection of level, time delay
and hysteresis:
Upper knob:
Setting of hysteresis on rela-
tive scale: 0 to 30% on set
value.
Centre knobs:
Current level setting on rela-
tive scale: 10 to 110% on full
scale.
Lower knobs:
Setting of delay on alarm time
on absolute scale (0.1 to 30 s).

it drops below the over volt-
age set level minus hystere-
sis (the hysteresis is the
same for both set levels).
Example 2
(latch enable active - under+under
current - 2 x SPDT relays (1 x
SPDT for PIC01) - TRMS)
DIC01:
Each relay operates
and latches when the current
drops below the respective
set level for more than the re-
spective delay time. Provided
that the current has exceeded
the respective set level plus
hysteresis, each relay releas-
es when the contact input’s
connection is interrupted.
PIC01:
The relay operates
when the current drops
below the higher set level for
more than the respective
delay time. Provided that the
current has exceeded the
higher set level plus hystere-
sis the relay releases when
the contact input’s connec-
tions is interrupted.
Note
Different delay times can be
used for appropriate reaction
according to the set points.
Example 3
(inhibit enable active - over+over
current with MI CT - DPDT
relay (SPDT for PIC01) - TRMS)
Provided that the contact
input’s connection is inter-
rupted, the relay operates
when the current flowing in
the MI CT exceeds the lower
set level for more than the
respective delay time. It
releases when the current
drops below the lower set
level minus hysteresis or
when the contact input’s
pins are connected.
Example 4
(inhibit enable active - over+over
current with A82-10 CT -
DPDT relay (1 x SPDT for
PIC01) - TRMS
Provided that the contact
input’s connection is inter-
rupted, the relay operates
when the current flowing in
the A82-10 CT exceeds the
lower set level for more than
its delay time. It releases
when the current drops
below the lower set level
minus hysteresis or when the
contact input’s pins are con-
nected.
Example 5 (DIC01 only)
(no contact input - under+over
voltage - 2 x SPDT N.D. relays
- plus/minus DC
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.
In this case the spare front
label has to be placed on the
device
for
adjustment.

level
Note
When the inhibit contact is
opened, if the input signal is
already in alarm position, the
delay time needs to elapse
before relay(s) activation.
