I. INITIAL INSPECTION and ASSEMBLY

Carefully unpack the instrument and accessories. Inspect for

damages made in shipment. If any damage is found, notify your

Jenco representative immediately. All packing materials should be

saved until satisfactory operation is confirmed.

MOUNTING PROCEDURE

1. Make a cutout on any

panel, with a thickness

of 1/16 in. (1.5 mm) to

3/8 in. (9.5mm).

2. Remove the mounting

assembly from the

controller and insert the

controller into the

cutout.

3. Replace the mounting

bracket assembly onto

the controller and

secure the controller to

the mounting panel.

Warning:

If the equipment is used in a manner not specified by the

manufacturer, the protection provided by the equipment may be

impaired.

Cleaning the instrument:

1. Be sure to remove the power before attempting to clean the

meter.

2. Use a lint free cloth and clean water or neutral detergent.

3. Wipe the outer surface of the instrument only.

4. Wipe-dry the instrument before powering again.

II. GENERAL INTRODUCTION

The Jenco Model 6308TuSS (Turbidity and Suspended Solids)

System is a rugged microprocessor based instrument assembled in

a watertight ¼ DIN case, designed for use in laboratories and

process control applications.

The model 6308TuSS microprocessor performs a self-diagnostic

routine every time you turn on the unit providing you with basic

information on the stability of the instrument.

The system simultaneously displays Turbidity and Suspended

Solids, relay status and current output in one graphic LCD screen.

The model 6308TuSS is equipped with 3 relays (2 programmable

high or low relay for Turbidity and Suspended Solids, 1

programmable for external cleaning); Turbidity and Suspended

Solids relays are hysteresis driven and configurable to CENTER

mode. The system also has a isolated 4-20mA analog output for

the Turbidity and Suspended Solids display.

III. USING THE JENCO MODEL 6308TuSS

A. FRONT PANEL

1. The [MODE/-] key.

1a. In the turbidity measuring page (TC-100、TC-500 、TC-

3000), press the “MODE” key to switch between the NTU and

the FNU turbidity units. The default is in NTU unit.

1b. In Calibration/Setting mode, pressing this key will move

the cursor to the next digit of the current active parameter.

1c. In Calibration/Setting mode, pressing this key for two

seconds will move you back to the previous parameter.

2. The [CAL / VIEW] key.

2a. In the normal mode, the display will go to

Calibration/Setting mode if you press this key for about two

seconds.

2b. During Calibration/Setting mode, pressing this key will

switch to the next available Calibration/Setting page.

Pressing this key at the last Calibration/Setting page will

return the user to the normal mode.

3. The []UP key.

During Calibration/Setting mode, pressing this key will

increment the current blinking digit of the active parameter.

4. The []DOWN key.

During Calibration/Setting mode, pressing this key will

decrement the blinking digit of the active parameter.

5. The []ENTER key.

During Calibration/Setting mode, pressing this key will save

the current modified parameter and move to the next

parameter on the page. If the parameter is the last one in the

page then it will move to first parameter on the next available

page.

6. The [ ] LIGHT key.

This key will turn on or turn off the backlight of the LCD.

The backlight will automatically turn off if there is no key

activity for about two minutes.

B. NORMAL MODE DISPLAY

1. TC-100 annunciator- this is the sensor selection mode. The

model 6308TuSS can work with 5 different 5 sensors, they are:

TC-100、TC-500、TC-3000、TCS-1000 and TS-MXS-A.

2. CURRENT OUT - this will display the actual reading of the 4-

20mA output. At power-on this will show “OFF” for about 3

seconds before going to the normal display mode. After exiting

the Calibration /Setting pages, a “FROZEN” message will be

displayed for about 3 seconds if the unit is not password locked.

3. 100.00 NTU annunciators- Turbidity display and unit (NTU or FNU)

or Suspended Solids display and unit (mg/L).

annunciator - this will be displayed if Calibration/Setting

pages are password locked meaning the user can’t

change the values unless the correct 4 digit password has been

entered.

5. H1 (High action relay 1) or L1 (Low action relay1) annunciator

- This is the status of the Turbidity or Suspended Solids relay 1, if

this is displayed then the relay is ON. H1 means the relay action

is HIGH while L1 means the relay action is LOW.

6. H2 (High action relay 2) or L2 (Low action relay2) annunciator

- This is the status of the Turbidity or Suspended Solids relay 2, if

this is displayed then the relay is ON. H2 means the relay action

is HIGH while L2 means the relay action is LOW.

7. C (Cleaning relay3) annunciator - “C” will appear when the

external cleaning relay is ON.

C. REAR CONNECTORS

Before connecting the probes, relays, analog output, RS485 and

power cord be sure that you are connecting to the right terminal as

shown above. Remember that the unit is on once the user plugs in

the power cord to an AC power supply.

1. Connect the AC line to the rear of the instrument. The model

6308TuSS can be used with 115VAC or 230VAC 50/60 Hz.

Power consumption is 6 watts. Make sure the EARTH connector

is connected to the earth lead of the AC power line.

2. Connect the proper load to the output relays. Make sure that the

load does not exceed the relay rating, 5 Amp at 115VAC and

2.5Amp at 230 VAC.

3. Set the proper load to the 4-20mA-output connector. Make sure

that the load impedance is less than 500 Ohms.

CAUTION: Make sure you connect the AC power to the correct

AC terminals. Connecting incorrectly may damage the unit

permanently.

D. TURNING ON/OFF THE INSTRUMENT

By just plugging the unit to a

correct AC voltage the unit

will be ready for use. There

is no Power key so

unplugging and plugging the

unit will turn off or turn on

the unit respectively.

After the unit is turned on, it

will perform some basic self diagnostics and will display “OK” or

“BAD”. If you received any “BAD” messages turn off the unit and

turn it on again.

If the message persists then you might need to call your distributor.

(See IX. WARRANTY).

IV. MODEL 6308TuSS MODES

A. MAIN DISPLAY MODE

The unit will always start in main display mode once it is turned on.

This instrument is designed to provide 2 distinct measurements:

1. Turbidity - a measurement of turbidity in NUT or FNU.

2. Suspended Solids -a measurement of suspended solids in mg/L.

B. CALIBRATION/SETTING MODE

Pressing the [CAL/VIEW] key for about two seconds during the

main display mode will bring-up the first page of seven pages of the

Calibration/Setting mode. Pressing [CAL/VIEW] key will switch to

the next page. At the last page, pressing [CAL/VIEW] again will

return the meter to the main display mode.
