5. S.A.(Sensitivity Adjustment) & SHIFT
5-1 S.A.(sensitivity adjustment)
: When ON and OFF with 1 point, out-put is chattered and easy to
receive influences of any noises, however, if you set the width of
S.A. as following diagram, stable control is possible.
Setting is possible from 0.1ppm to 4.0ppm (±2.0ppm) and it was set as
0.1ppm when ex-factory.
Set example) LOW set : occasion of lower limit 5.0ppm
S.A : 0.2ppm
SHIFT : 0.0ppm
Set example) HIGH set : occasion of upper limit 8.0ppm

5-2 SHIFT
: A constant error is occured against target value when ON and OFF.
This error is called as off-set and this off-set can be controlled to
target value without any errors, if you use this SHIFT function in
SAMSAN CROWN controllers.
Setting is possible from 0.0ppm to 2.0ppm and it was set as 0.0ppm
when ex-factory.

6. INSTALLATION & WIRING
6-1 Installation environment
: Install at good conditioned place as follows
(1) Airy place ( ambient temperature : -5 ℃ ～40 ℃ )
(2) Adequate protection should be provided to keep the controller from
being exposed to direct sunlight or rain
(3) Moistureless place that ambient humidity is less than 85%
(4) A place without the mechanical vibration
(5) A place with sufficient space for easy maintenance and wiring
(6) A place without dust, corrosive gas and any influences of electronic
power
6-2 Installation method
(1) Panel mounting type
※ Refer to out-drawing for panel cutting
(2) Insert 2 eas of mount bracket in the upper and lower holes and
fasten the bolts with + ○ driver.
6-3 Connection of sensor cable
: Cable connector should be kept in dry and clean to get a stable value.
(1) Standard cable length is 10m.
In case of extension over than 10m, use the connector box and
exclusive cable for DO supplied by SAMSAN CROWN.
(2) Install at the place without any influences due to motors of machinery.
(3) Lead cable of sensor should be fully left for calibration of standard
solution and checking of sensor.
(4) Contact to our technical sales dept. in case of using Temperature
Compensation electrode.
6.8 k Ω at 25 ℃ or 500 Ω at 25 ℃
A : Anode
K : Cathode
T. T : Temp. compensation electrode terminal
E : Shield cable
※ Refer to following drawing for wiring to terminal.
6-4 Connection of output cable
(1) Output signal of DC 4～ 20mA against measuring range come out.
※ Max. load resistance : 500 Ω
0.00 ppm → 4 mA
3.75 ppm → 8 mA
7.50 ppm → 12 mA
11.25 ppm → 16 mA
15.00 ppm → 20 mA

(2) Output
6-5 Connection of power cable
: Connect with correct voltage
(1) Power switch is attached to terminal board in the back of the controller
(2) Surely ground for your safety
7. CALIBRATION & OPERATION
Prior to operating, adjust controller & using sensor with standard solution .
Regular calibration is surely needed because character of sensor changes
when used for long time.
7-1 ZERO Calibration
(1) Remove DO chip from probe.
(2) Set indicating value on window as 0 ppm.
(3) Set DO chip in probe again.
7-2 SPAN Calibration ( atmosphere calibration )
: If indicating value is stabilized after openning the probe to the
atmosphere, set the indicating value as 12.0 ppm with span volume.
8. REPAIR
8-1 Controller should be calibrated once in a month.
8-2 Electrode should be cleaned once in a week ( once in a day in case
of using in vilulent waste water ).
8-3 If sensitivity & response of electrode is bad, clean DO chip with
gause wetted by alcohol as soft as possible.
