Product Description
EIK is a precise AC/DC over
current (shunt) metering re-
lay. Measures the voltage of
an externally connected
standard shunt also for high
current applications. The built-
in LED's indicate the exact
status of the output relay. The
advantage of using the latch
function is that the output re-
lay can be kept energized so
e.g. a short-circuit can be
indicated.

Mode of Operation
EIK measures both AC and
DC current (voltage) through
an external standard 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
time delay.
The relay releases when the
current (voltage) drops min.
5% below the set level (see
hysteresis) or when power
supply is interrupted.
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
time delay.
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 has expired or until
the measured value drops
below the fixed hysteresis
(5%) again.
Range/Level/Time Setting
Centre knob:
Current (voltage) level setting
on relative scale.
Lower knob:
Setting of ON delay on abso-
lute scale (0.1-10 s).
Upper knob:
Setting of current (voltage)
range on rotary switch.
When using Y1 & Y3 the scale
is multiplied by 2.
Hysteresis
Normally 5%. The hysteresis
can be extended by inserting
a resistor between terminals
Z1 & Z2.
