:
As the display value is swing near by the set point to cause the relay on
and off frequently. The function is to avoid the relay on and off frequently
such as compressor…….etc.,

):
Settable range from 0.0(s)~9(m)59.9(s);
This function is programmable in Relay 4 only.
If the Relay 4 set to be Go function, the relay will compare with

:
.
The function is to avoid the miss action caused by noise. Sometime, the
display value will swing caused by spark of contactor…etc.. User can set
a period to delay the relay energized.

External Control Inputs(ECI)
The three external control inputs are individually programmable to
perform specific meter control or display functions. All E.C.I. have been
designed in level trigger actions. Please pay attention, the ECI1 or ECI2
input will be disable while UP or Down Key has been set to be “
yes
”.
Functions:
Relative PV / PV Hold / Reset Max or Mini. Hold /

/
Reset
for Relay Energized latch
programmable.
Relative PV
reLpv
:
The
[
ecI_
]
can be set to be
reLpv
function. When the
E.C.I. is closed, the reading will show the differential value.
The relay energized with latched function is for electrical
safety and human protection.
For example, a current meter relay installed for the over
current alarm of motor. Generally, over current of motor
caused by over load, mechanical dead lock, aging of
insulation and so on.
Above cases will alarm in the meter, if the user doesn't figure
out the real reason and re-start the motor. It may damage the
motor. The functions of Hi.HLd & Lo.HLd are designed must
be manual reset the alarm after checking out and solving the
issue. It's very important idea for electrical safety and human
protection.
As the PV Higher (or lower) than set-point, the relay will be
energized to latch except manual reset by from key in
[

Mrst
:
The function has been designed not only a meter but also an
I/O interface. In the case of motor control cabinet
can't get the
remote function. It's very easily to get the ON/OFF status of
switch from CS2 series with RS485 function.
If the
[
ry_.md
]
had been set
do
, the relay will be
energized by RS485 command directly, but no longer to
compare with set-point.
Start delay band and Start delay time:
When the
[
dsply
]
function in
[
input group
]
selected
maXhd
or
miNhd
, the display will show Maximum or
Minimum value.
The
[
ecI_
]
function can be set to be
Mrst
function to reset the maximum and minimum value in
[
User Level
]
by terminals of ECI
(close). Please refer to
the figure as below.
The functions have Been designed for,
►
To avoid starting current of inductive motor (6 times of rated current)
with alarm.
►
If the
ry_.md
relay energized mode had been set to be
lo
(Lo) or
lOhld
(Lo & latch). As the meter is power on and no input to display
the "0" caused the relay will be energized. User can set a band and
delay time to inhibit the energized of relay.
