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 is
closed.

CS2 series offers 3 point external control inputs
(ECI). They can be programmable individual with multi
display and control functions. The front key function can
be set to execute ECI function, but ECI terminals will be
disabling. The ECI terminal input was designed by level
trigger. Please refer to description as below,
Relative PV(∆PV) or Tare (reLpv)
The [ ecI_]can be set to the reLpv(Relative PV)
function. When the ECI is closed, the reading will show
the differential value with PV. Please refer to Display
function section previously.
PV(Present value) Hold (pVhld)
The [ ecI_]can be set to the pVhld(PV Hold)
function. The display will be hold when the E.C.I. is
closed except the ECI is to be open. Please refer to
Display function section previously.
Reset Maximum or Minimum Hold( Mrst) for PV
The [ ecI_] function can be set to the Mrst
function to reset the maximum and minimum value by
terminal of ECI.
Especially, the [dsply] function in [input group]
can be set to the maXhd or miNhd to operate in
coordination with DO of PLC. It is easier to achieve the
maximum value testing in automation. Please refer to
the below figures.

■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 [ Csel]to select field.
●[ Csel](Calibration parameter selection): Field calibration wouldn’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?

■Bank Function(Suffix-3BK) for CS2-VA, CS2-RS
The function is for CS2-VA and CS2-RS for controlling difference process with a same meter.
For example; a pressure testing equipment; it has to measure multi-range with difference pressure transducers. The
meter can be pre-set 4 groups parameters to show difference scales and relay energized with difference set-points.
The operator just selects the bank number (bank1) to meet the process (product A). To make easier operating and to
avoid making mistake in process operating.
4 banks pre-set for all relay functions are correspondence to 4 difference scaling, decimal point, above select by 3
External Control Inputs(E.C.I.) or front key.
Example: Current testing
Product A: Current rated: 5A; NG: over 5A
Product B: Current rated: 100A; NG: over 100A
Setting: BANK1: [dp]: )000 [lOsc]: )000 [hIsc]: %000
[ry!md]: hi [ry!sp]: %000 [ry!rd]: )0)5
BANK2: [dp]: )00 [lOsc]: )00 [hIsc]: 10)00
[ry!md]: hi [ry!sp]: 10)00 [ry!rd]: )0!0
[ ecI1]: banK1 [ ecI2]: banK2; connect a selector (or DO of PLC) to ECI1 and ECI2 terminals
●The order want to produce Product A must switch selector to A(Label A on panel), and ECI.1 close that the square
green LED bright to express the meter will work as per bank1 set. When PV is over 5.000A that relay1 will be
energized.
●The second order want to produce Product B must selector to B(Label B on panel), and ECI.2 close that the square
green LED bright to express the meter will work as per bank2 set. When PV is over 100.00A that relay1 will be
energized..
Only 1 Bank can be selected, if it is double selection. The priority is Bank1 > Bank2 > Bank3 in order,
