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) anel 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 5m
In case of extension over than 5m, use the connector box and
SAMSAN CROWN cable for RC.
(2) Install at the place without any influences due to motors of machinery
(3) Contact to our technical sales dept. in case of using Temperature
Compensation electrode.
A : ANODE
K : CATHODE
T. T : no connection
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
0.50 ppm → 8 mA
1.00 ppm → 12 mA
1.50 ppm → 16 mA
2.00 ppm → 20 mA

6-5 Connection of power cable
: Connect with correct voltage
(1) ower switch is attached to terminal board in the back of the controller
(2) Surely ground for your safety
7. CALIBRATION & O ERATION
7-1 ZERO Calibration
( Residual chlorine concentration of sample water is in case of less
than 0.5ppm)
(1) Close the stop valve in sampling line and make for the water not
to be entered to holder.
15～20minutes later, residual chlorine concentration will be to "0"
if it's electrolyzed.
(2) Then adjust to "0"ppm with ZERO volume on RC controller
( Residual chlorine concentration of sample water is in case of over
than 0.5ppm)
(1) You need much time till it's changed to "0", in this case, immerse
residual chlorine electrode in beaker with municipal water of
residual chlorine concentration 0 ppm. If it's stabilized, adjust
to "0"ppm with ZERO volume on RC controller.
7-2 S AN Calibration
(1) Measure residual chlorine value of sample water with color
comparison Meter. Then adjust the value that's appeared
in color comparison meter with S AN volume of RC controller.
If sample water concentration is low, use liquid for S AN of
0.5～ 1.0 ppm. If it's stabilized, adjust with S AN volume on
RC controller.

7-3 CAL Volume Adjustment
(1) ut CAL. MEAS. Switch to CAL position before entering to
continuous measuring.
(2) Adjust to 1.0 ppm with CAL volume.
Notice : After you use the RC controller, if 1.0ppm don't appear on
RC controller, you should wash or re-generate or change
the electrode because electrode's sensitivity become bad.
7-4 Measure continuously, adjusting drain valve if calibration is finished and
calibrate ZERO, S AN in 1～ 2 weeks.
8. REGENERATION & STORAGE OF ELECTRODE
8-1 Regeneration
: In case that calibration is impossible due to becoming bad of
electrode sensitivity, Regenerate electrode as follows.
(1) Wash Anode & Cathode cleanly in 3% HCL with soft brush.
(2) Then clean them with clean water.
(3) Make 100ppm NaOCL and put the electrode in 100ppm NaOCL
for over than 1 day after connecting Anode cable with Cathode
cable in the end of lead cable of electrode.
(4) Calibrate after driving with regenerated electrode for over than
3 hours.
8-2 Storage
: In case of stop of driving for a long time, separate electrode from
holder and storage in clean water in connecting Anode cable with
cathode cable in the end of lead cable. Don't open to atmosphere.
9. CHANGE OF CARTRIDGE FILTER SAM LING LINE
Change cartridge filter in proper time because it's difficult to get
stable value, if filter is polluted.
10. TROUBLE SHOOTING
In case of having any troubles in RC controller, surely check the
followings.
10-1 Basic checking points
(1) Do you use this RC controller on the purpose of measuring
residual chlorine that generates when chlorine gas or NaOCL
is poured into ?

10-2 Don't total residual chlorine occupy the majority due to having
much NH3compound in the water ?

Not to indicate
Electric power is supplied
to controller ?
Turn on the power switch.
Calibration is correct ?
Re-calibrate by instructions.
Don't you have any
problems to connect with
cables ?
Refer to terminal board of
item 12.
Don't you have any
problems to holder and
over-flow level ?
Adjust stop valve.
Residual chlorine is
included in
sampling water ?
Check with color comparison
meter.
Isn't the filter plluted ?
Change the filter to new one.
pH value of sampling
water isn't
over than pH 8 ?
Adjust pH value between
pH 6 and pH 8.
Not to calibrate and
instructing valvue
go down
Sensitivity went down due
to pollution of electrode.
Clean the electrode and
regenerate.
In case of opening the
electrode to atmosphere
for a long time.
Drive continuously till
instructing value is appeared.
