EII is a precise AC/DC over
current metering relay and
often used in applications
where small loads have to be
controlled. The advantage of

using the latch function is that
the output relay can be kept
energized so that e.g. a short-
circuit can be indicated.

Mode of Operation
EII measures both AC and DC
over current through an inter-
nal shunt.
Example 1
(no connection between ter-
minals Z1 & Z2)
The relay operates when the
measured value exceeds the
set level for more than the set
delay time.
The relay releases when the
current drops min. 5% below
the set level (see hysteresis),
or when power supply is inter-
rupted.
Example 2
(connection between termi-
nals Z1 & Z2)
The relay operates and latches
in operating position when the
measured value exceeds the
set level for more than the set
delay time.
Provided that the voltage has
dropped min. 5% below the
set point (see hysteresis), the
relay will release when the in-
terconnection between termi-
nals Z1 & Z2 is interrupted, or
power supply is interrupted.
If the measured value is above
the set level when power sup-
ply is applied, the relay will
operate immediately with no
time delay.
The yellow LED is flashing until
the delay-time has expired or
the measured value drops
below the fixed hysteresis
(5%) again.
Range/Level/Time Setting
Upper knob:
Setting of current range on
rotary switch.
Centre knob:
Current level setting on rela-
tive scale.
Lower knob:
Setting of ON delay on abso-
lute scale (0.1-10 s).
Hysteresis
Normally 5%. The hysteresis
can be extended by inserting
a resistor between terminals
Z1 & Z2.
Approx.
10%: 39 k
25%: 12 k
50%: 4.7 k
75%: 2.2 k
Latch: <500
