GETTING STARTED

IMPORTANT

7-DAY CHART ROTATION

Dickson Chart Recorder accuracy specifications are only valid with the use of authentic

Dickson brand charts and pens. The specifications for chart printing, die cutting and paper

0 TO 100°F

absorption rates, and the complementary bleed rate specifications of pens are critical factors

in determining system accuracy.

QUICK START

TO BEGIN OPERATION

1. Remove the protective pen cap(s).

2. Connect probe(s).

a. KT8P0/2/3: Make sure the KTC probe is connected

firmly to the Replaceable Sensor™ and that the

Replaceable Sensor™ is plugged in firmly to the

chart recorder.

b. KT856: Make sure the KTC probe is connected

firmly to the Replaceable Sensor™ and that the

Replaceable Sensor™ is plugged in firmly to the

chart recorder.

3. Insert batteries and plug in AC adapter (See Figure 3).

a. KT8P0:4 AA batteries required

b. KT8P2/3 & KT856: 4 AA batteries backup power

Unit will power on.

4. The instrument will move pen(s) to the appropriate

readings.

5. Install the chart that matches the DIP SWITCH settings.

6. Press the PEN HOME key to move the pen(s) to the

outside of the chart. The pen(s) is automatically raised

off the chart.

7. Remove the old chart, place the new chart on the

CHART HUB being certain that the edge of the chart

slides under the Chart Guide Clip located at the outside

of the chart.

8. Set the appropriate time. There are two ways to adjust

the chart and set the appropriate time:

BUTTON OPERATION

ON/OFF

The ON/OFF key turns the unit on and off.

PEN HOME

If the pen is located on the outside edge of the chart, press

PEN HOME to move pen to recording position. If the pen is

located on the chart, press PEN HOME to move the pen to

the outside edge of the chart.

ALARM (OPTIONAL)

» Pen 1 =Red Pen

» Pen 2= Blue Pen

a. Set the chart time manually by inserting a coin into

the groove in the chart hub and turning clockwise

until the correct hour (and day if applicable) on the

chart is referenced to the timing arrow (just to the

right of the pen tip on the dial). Press PEN HOME to

move the pen(s) back onto the chart.

b. To adjust the chart time, press and hold ADJUST-UP

and ADJUST-DOWN buttons located on the back of

the unit next to the dip switch.

The green LED will blink rapidly for about five

seconds, then the LED will remain solid green.

While in this state the ADJUST-UP button will move

the chart backward (counter clockwise) and the

ADJUST-DOWN button will move the chart forward

(clockwise).

only.

Rotate the chart until the correct hour (and day if

applicable) on the chart is referenced to the timing

arrow. Once you have set your chart, press the PEN

HOME button to exit Chart Adjust Mode. The unit

will take one minute to exit the Chart Adjust Mode

once PEN HOME is pressed. Press PEN HOME to

move the pen(s) back onto the chart.

c. Place the KT8 recorder on a flat vibration-free

surface. Be sure it is in a vertical position and level.

For best performance and longevity, the location

should be a clean environment, free from dust

and corrosive fumes. Do not exceed temperature

specifications. Wall Mount: Keyhole slots are

provided on the KT8 recorder for wall mounting.

1. To set the ALARM, make sure unit is on and press and

hold the ALARM button. The LED will blink red rapidly

for about five seconds, then the LED will turn solid

green. Release the ALARM button and the LED will turn

solid red. At this point the display will show "On" or

"Off".

Pressing either the ADJUST-UP or ADJUST-DOWN

buttons, located on the back of the unit next to the dip

switch, will toggle the ALARM on or off.

2. Pressing PEN HOME will scroll to the next ALARM

options.

» Pen 1 ALARM minimum

» Pen 1 ALARM maximum

If KT856 two pen model, the additional options are:

» Pen 2 ALARM minimum

» Pen 2 ALARM maximum

3. In order to set pen(s) ALARM minimums and maximums,

pressing ADJUST-UP will increase the ALARM value,

and pressing ADJUST-DOWN will decrease the ALARM

value. There is acceleration if the ADJUST-UP button is

held down.

Repetitively pressing the PEN HOME button will scroll

through the five options until the ALARM button is

pressed to exit from ALARM adjust. Each press of the

PEN HOME or ALARM button will store the new settings.

The unit will take one minute to exit ALARM Set Mode

once the ALARM button is pressed.

4. If the ALARM is triggered, the LED will show as solid red

and the ALARM will sound. Press the ALARM button to

silence the audible ALARM.

POWER

The KT8 operates on AC power with an optional 4 AA

battery backup. Depending on chart rotation selected and

model, battery backup will last:

KT8P2/3 AND KT865

» 24 Hour Chart Rotation = 1 day backup

» 7 Day Chart Rotation = 2 day backup

» 31 Day Chart Rotation = 1 week backup

Note: ALARM and relays will not operate under battery

only power.

KT8P0 at 70°F

» 24 Hour Chart Rotation = 1 month backup

» 7 Day Chart Rotation = 6 month backup

KT8P0 at 32°F

» 24 Hour Chart Rotation = 3 week backup

» 7 Day Chart Rotation = 4 month backup

Note: Unit should not be placed in an environment

below 32°F

PENS

The blue pen has a longer pen arm and records channel

2 temperature (depending on your dip switch selection).

The red pen has a shorter arm and records channel 1

PEN HOME ADJUST

If over time the pen location does not match the display,

you may need to adjust the pen location on the chart. A

PEN HOME Adjustment will not affect calibration of the

sensor, but rather corrects for the natural drift that occurs

with mechanical moving parts over time.

1. While the unit is on, press and hold both PEN HOME

and ON/OFF buttons until the LED is solid green.

ALARM RELAYS

The SPST 24V 500mA relay contacts are normally open

and will close on ALARM conditions when the ALARMs

are enabled. Relay contacts are always functional when

the ALARM is enabled. The relay will close only during

minimum and maximum ALARM conditions. The KT856

has 2 sets of relay contacts which operate independently.

Relays will not operate under battery only power

conditions.

CH1 = PINS 1,2,3

• Pins 1 and 2 make contact

when CH1 is in alarm

• Pins 1 and 3 make contact

when CH1 is not in alarm

CH2 = PINS 4,5,6

• Pins 4 and 5 make contact

when CH2 is in alarm

• Pins 4 and 6 make contact

when CH2 is not in alarm

LED Indicators

• Solid Green — AC Power with Battery Backup

• Flash Red — AC Power with Low Battery or No Battery

• Blinks Green — Battery Only

• Solid Red — Battery Only (Low Battery)

Note: KT8P0 operates on battery only and will blink

one time every minute to conserve battery life.

glide under the blue pen. The blue pen indicates the correct

time and the red pen precedes it by 3/16 of an inch.

Release the PEN HOME and ON/OFF BUTTONS. The

LED will flash amber and green for one second then the

LED will turn off.

Note: Press PEN HOME first so the unit will not turn off

2. The pen(s) will move to the outer edge of the chart and

the shorter red pen will move to the outer chart ring
