Remote Display function

CS2 series has been built
-
in an innovation function
called remote display function.
In past, The meter only receive 4~20mA or 0~10V
from AO card or BCD card of PLC. We support a new
solution by RS485 for replacing the PLC's AO or BCD
cards which it can save costs of AO and wiring to PLC.

The data(number) will be same as PV that will compare
with set-point, analogue output and ECI functions so the
data could control analogue output, relay energized and
so on.
CS2 series can be used as Remote Terminal Unit
(RTU) for monitoring and controlling in a SCADA
(Supervisor Control And Data Acquisition) system. It's
not only can be read the measured value and DI
(external control inputs) status but also controls the
relays output (DO) by RS485 communication ports.

Field Calibration (for CS2-SG / CS2-PM / CS2-RS)
In pass time, the engineers have to take a lot of time to adjust and calibrate meters or converters which the
purpose of co-coordinating with zero and span of machinery structure for the Load Cell or Potentiometer measuring.
Now, our CS2-SG, CS2-PM and CS2-RS with innovation functions against above to make the engineer operated easily
and smoothly that it's
called “Field Calibration”. The procedures are descripted as below;
●
Enter the right pass code
[
Fcode
]
and access to the Field Calibration Level.
●
Adjust the structures of machinery or & equipments to be "lower status".
●
The low calibration of machinery structure is not need the exactly "zero" to calibrate, because of the "field calibration"
function could be calibrate any lower point.
●
Move next page to the
[
caLlo
]
and waiting for the value till stable, then pressed
Key to read the signal low of
sensing device.
●
Waiting for above reading stable (around 3~5seconds), press
Key again to complete the calibration lower point,
and go to
[
caLls
].
●
[
caLls
]
is the page of low scale setting that is relative to the calibration low point.
●
Press
Key to next function index
[
caLhi
]
.
●
Adjust the structures of machinery or & equipments to be "higher status".
●
The high calibration of machinery structure is not need the exactly "span" to calibrate because of the "field calibration"
function could be calibrating any higher point.
●
In
[
caLhi
]
page, waiting for the value till stable, then pressed
Key to to read the signal high of sensing device.
●
Waiting for above reading stable (around 3~5seconds), Press
Key again to complete the calibration higher point,
and go to
[
caLhs
].
●
[
caLhs
]
is the page of high scale setting that is relative to the calibration high point.
●
Press
Key to next functions
[

to select

(Calibration parameter selection): Field calibration would
n’t change the default calibration. After user
completing the field calibration, it can also select default calibration if the user wants.
►
As the user finished the procedures of field calibration, the field calibration datum has been saved in EEProm and it
can't change the default(factory) calibration datum. Even the field calibration has been done, the user can still select
either default calibration or field calibration.
►
If the user select field calibration, the
[
lOsc
]
(step A-4) and
[
hIsc
]
(A-5) will be replaced by
[
caLls
]
and
[
caLhs
]
which it can not to be changed by anyone. If user has to change the scaling, it's the only way to access field
calibration level to set in
[
caLls
]
(step F-2) and
[
caLhs
]
(step F-4).
►
After selecting the
deflt
or
field
, please double check the
[
lOsc
]
(step A-4) and
[
hIsc
]
(A-5) whether are
corrected or not?
