[
ry!sp] (Hi) > PV > [ry@sp] (Lo)
Go-2.3 go-@3 : This function is programmable in Relay 4 only.
If the Relay 4 set to be Go function, the relay will
compare with [ry@sp] and [ry#sp].
Go relay energized when the condition is
[
ry@sp] (Hi) > PV > [ry#sp] (Lo)
DO function do :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 RS-485
function.
If the [ry_.md] had been set do , the relay
will be energized by RS-485 command directly,
but no longer to compare with set-point.
Moving average:
Jittery Display caused by the reasons as like as noise or unstable
signal. User can set the times to average the readings, and get
smoothly display.
The meter’s sampling is 15cycle/sec. If the [ Mavg](Moving
Average) set to be 3 expressed the display update with 15
times/sec.
In the first updated display value will be same as average function.
In the next updated display value, the function will get the new
fourth sample (sample 4) then throw away the first sample (sample
1) that the newest 3 samples(sample 2,3,4) will be calculated for
the updated display value.
Digital Filter: The digital filter can reduce the magnetic noise in field.
The digital filter can reduce the influence of spark noise caused by
magnetic of coil.
If the values of samples are over digital filter band (fix in firmware
and about 5% of stable reading) 3 times (Digital Filter set to be 3)
continuously, the meter will admit the samples and update the new
reading. Otherwise, it will be as treat as a noise and skip the samples.

Hi.HLd hIhld (Lo.HLd lOhld ) :
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 [ user
level] or [ eci](ECI) set to be rYrst rYrst is closed.
Start delay band and Start delay time:
The functions have Been designed for,
 To avoid starting current of inductive motor (6 times of rated
current) with alarm.
 If the y_.md r 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.

Fine zero & span adjustment:
Users can get Fine Adjustment of analogue output by front key of
the meter. Please connect standard meter to the terminal of
analogue output. To press the front key(up or down key) of meter to
adjust and check the output.
Zero adjust [aOzro]: Fine Zero Adjustment for Analog Output;
Settable range: -38011~27524;
Span adjust [aOspn]: Fine Span Adjustment for Analog Output;
Settable range: -38011~27524;
Remote Display:
The meter will show the value that received from RS-485 command.
In past, The meter normally receive 4~20mA or 0~10V from AO or
digital output from BCD module of PLC .We support a new solution
that PV shows the value from RS-485 command of master so that
can be save cost and wiring from PLC.
When the [ dsply] set to be RS-485, it means, the PV screen will
show the number from RS-485 command & data. The data(number)
will be same as PV that will compare with set-point, analogue
output and ECI functions so that is to control analogue output, relay
energized and so on.
Field Calibration:
In pass time, engineers have take a lot of time to adjust meters
or converter to meet the structure of machinery zero and span for
the Load Cell measuring. Now, our CS2-SG support easier process
to do it called “Field Calibration”
High Speed Mode: Code: -HSM
According the scaling, the controller can be specify higher
sampling rate up to 60times/second(Average set to be 1). The relay
trip, analogue output will be quicker response according to update
of Present Value.
Calibration System calibration by front key. The process of
calibration, please refer to the operating manual.
CS2 series supports Modbus RTU mode protocol to be used as
Remote Terminal Unit (RTU) for monitoring and controlling in a
SCADA (Supervisor Control And Data Acquisition) system. The
baud rate can be up to 38400 bps. It's not only can be read the
measured value and DI (external control inputs) status but also
controls the relays output (DO) by RS-485 communication ports.
