GENERAL INTRODUCTION
The Jenco Model 6309PDTF (pH, DO and Temperature) 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 6309PDTF microprocessor allows the user to easily
recalibrate the parameters for the probes. The DO system requires
only a single point calibration, regardless of which dissolved oxygen
display you use. The microprocessor also performs a self‐
diagnostic routine every time you turn on the unit providing you
with basic information about the stability of the instrument.
The system simultaneously displays pH, DO, Temperature, Relay
status and current output in one LCD graphic screen. The LCD also
includes a backlight for low‐lit environments. This system uses
glass electrode for the pH, a “polygraphic clark” membrane for the
DO and a precise thermistor for temperature, providing you with
accurate readings for all your measurements.
The model 6309 PDTF is equipped with 5 relays (2 programmable
High/Low action relays for pH, 2 programmable High/Low relays
for DO and 1 programmable High/Low relay for Temperature); all
relays are hysteresis driven and configurable to CENTER or EDGE
mode. The system also has an isolated 4‐20mA analog output, offset
and span configurable for the pH or DO display.
The model 6309 PDTF comes with a RS485 interface which can
easily let the user log all data (from multiple model 6309 or
6308) with an IBM©PC/AT compatible computer. For
4
advanced users, the model 6309 PDTF may also be remotely
controlled from main display mode to all
calibration/setting
modes.

a.
:
‐ This will be displayed if Calibration/Setting
pages are
p
assword locked meaning the user can’t change the
values unless the correct 4 digit number has been entered.
b.
RELAY:
‐ This will show the status of the relays. At Power‐ON
a“
DISABLED
” message will be displayed for about three
seconds beforegoingto
NORMAL
or
CHECKSTATUS
operation. After exiting the Calibration/Setting pages and the
unit is not password locked, a “
FROZEN
”messagewillbe
displayed for about three seconds before returning to
NORMAL
or
CHECK STATUS
operation. IF no relay is ON then the
“
NORMAL
” message will be displayed. IF any relay is ON then
the “
CHECK STATUS
”willbedisplayed.
c.
CURRENT OUT:
‐Thiswilldisplaytheactualoutputofthe4‐
20 mA output. At POWER‐ON this will show “
OFF
” for about
three seconds before going to normal operation. After exiting
the Calibration /Setting pages a “
FROZEN
” message will be
displayed for about 3 seconds before returning to normal
operation. An “ERROR” display here means that the absolute
difference between 4mA and 20mA is less than 1.0 pH (if pH
7
LINEAR or pH ANTILOG is selected) or less than 1.0 % (if DO
LINEAR is selected and RELAY/mA is set at %) or 0.10 ppm (if
DO LINEAR is selected and RELAY/mA is set at ppm) and that
the current output is disabled.
d.
H,L: ‐ One or both of these annunciators will be displayed if the
left side reading (LARGE FONT DISPLAY) triggered the
respective relay settings. The rightmost character will indicate
RELAY 1 if the display is pH or RELAY 3 if the display is DO The
leftmost character will indicate RELAY2 if the display is pH or
RELAY 4 If the display is DO If the display is DO the
annunciators will only indicate the unit selected at the
RELAY/mA option in the DO CALIBRATION page.
H:
High action relay and the relay is energized.
L:
Low action control and the relay is energized.
e.
LARGE FONT DISPLAY ‐ This reading uses the biggest font and

f.
H,L: ‐ One or both of these annunciators will be displayed if the
left side reading (MEDIUM FONT DISPLAY) triggered the
respective relay settings. The rightmost character will indicate
RELAY 1 if the display is pH or RELAY 3 if the display is DO.
The leftmost character will indicate RELAY2 if the display is pH
or RELAY 4 If the display is DO. If the display is ORP the
annunciators will only indicate the unit selected at the
RELAY/mA option in the DO CALIBRATION page.

temperature reading triggered the temperature relay setting. The
temperature relay setting can be configured to HIGH or LOW.
H: High action relay and the relay is energized.
L:
Low action control and the relay is energized.
i.
Temperature ‐ the current temperature of the solution.
C. REAR CONNECTORS
Before wiring the probes, relays, analog output, RS485 and power
cord be sure that you are connecting to the right terminal as
shown below (be sure the ac‐plug is not plugged‐in). Remember
that the unit is ON once the user plugs in the power cord to an
AC power supply.
9
A.
Connect the AC line to the rear of the instrument. The model
6309 PDTF can be used with110VAC or 220VAC 50/60 Hz .
Power consumption is 6 watts. Make sure the EARTH
connector is connected to the earth lead of the AC power line.
B.
Connect the proper load to the output relays. Make sure that the
load does not exceed the relay rating, 5 Amp at 115VAC and 2.5
Amp at 230 VAC.
C. 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 CORD TO THE
CORRECT AC TERMINALS. CONNECTING INCORRECTLY
MAY DAMAGE THE UNIT PERMANENTLY.
