INSTRUCTION MANUAL

CR4-KPP RECORDER FEATURES:

The CR4 is a precision multi-function reco rder. With t he KPP adapter the CR4-KPP becomes a dual pressure
recorder with a digital display, two media compatible pressure sensors, an interface adapter, and a cable to connect
the interface adapter to the recorder. The recorder was designed with the user in mind. No special knowledge is
required to operate the CR4-KPP. The menu driven setup is logically simple and user friendly. All parameters are
shown on a two line alpha numeric LCD display. The backlighting of the d isplay enhances visibility under marginal
lighting conditions.

The CR4-KPP uses two independent pens and records information on a six-inch circular chart. Each pen is uniquely
colored to maximize chart readability. The r otation of the chart may be set to single turn or continuous.

In addition, a full function alarm feature is provided. The alarm of the CR4-KPP can be set to sound an audible
signal when the pressure 1 and/or pressure 2 has exceeded an upper or lower limit. Each limit is individually set
from the front panel. A delay time before the alarm is activated may be set by the user to prevent nuisance alarms.
Low power normally open relay contacts are provided to allow activation of a remote alarm, phone dialer or
annunciator.

Power is supplied through a 120 VAC 50/60 Hz plug-in adapter. External power may be supplied from any 12
VDC source such as automotive, marine, or other battery. Battery backup for 48 hours is featured to provide
operation during temporary power loss.

All functions of the CR4-KPP are accessed through five pushbuttons located on the front panel. Selectable
functions are retained in memory to avoid re-entering settings in the eve nt of a power failure.

QUICK START

1. Connect power supply adapter to CR4-KPP through j ack on right side of unit.

2. Plug power supply adapter into 120 VAC outlet.

3. Press the “ON” button.

4. Pens will move to the "Home" position (the outermost part of the chart).

5. Pens will then go to a position on the chart according to the display reading. This is called the RUN
Mode. (Unit is always in the RUN mode when display is showing pres s ure readings.)

MENU OR RUN?

The CR4-KPP has two basic modes of operation:

MENU mode. To review or change settings.
RUN mode. To display present conditions and record them.

If MENU mode is selected the user can:
Set Chart Speed/Range.
Set Single or Continuous Chart Rotation.
Set Alarm Status (Alarm delay section of MENU will not show when the alarm is disabled.):

Alarm Delay = 0

Alarm Delay = 10 Minutes /20 Minutes /1 Hour /2 Hours

If the ALARM is Enabled the following Menu Selections will be available;

Set Pressure 1 High Limit
Set Pressure 2 Low Limit.
Set Pressure 1 High Limit.
Set Pressure 2 Low Limit.
After menu setting, unit will automatically go into the RUN Mode after 30 seconds.

If the RUN Mode is selected:
The display will show Pressure 1 and Pressure 2.
While in the RUN mode, the user can:

Home the Pens by pressing the HOME switch. (Allows for easy changing of charts and pens.)

Set Blue Pen position.
Set Red Pen position.

Advance the chart by pressing the ADV button. (To match present time with chart.)
Setting Pressure Sensors to 0 PSI.

How to Change the Chart.

1. Press the HOME button to move the pens to the outer ed ge of the chart.

2. Lift the pens with the lever. (Just enough to lift the pens from the chart.)

3. Remove the old chart.

4. Install the new chart onto the spindle.

5. Rotate the chart to the starting point with the ADV button.

6. Lower the pens.

7. Press the MENU button. This will put Recorder in the RUN Mode.

8. If the pen(s) position needs adjustment, see Pen Adjustment section below.

CHART SPEED AND RANGE

The CR4-KPP offers 24 combinations of Chart Ranges and Chart Speeds to match a wide variety of applications.
All functions of Chart Speed and Chart Range have been combined in one menu to make the necessary selections as
easy and as fast as possible. As a furt her aid to the user the Supco Chart number is shown on the display for any
combination of Chart Range and Chart Speed.
Chart Speed is the term used to describe the time it takes for the recording chart to make one complete revolution.
Different applications will require different chart speeds. For example, the 31 Day Chart would generally be used
where long term monitor i ng is required and frequent changing of the charts would be undesirable. The main
disadvantage of this is that short term variations in pressure will record as a single line or step on the chart. In
applications that have wide or frequent pressure variations the user may prefer a faster chart speed for more accurate
analysis.
The fastest chart completes one revolution in 1 1/2 hours. This allows the user to record short term variations in
pressure in great detail.
Chart Range can be selected by the user for PSI or BAR. The recorder will retain this information even when the
power is disconnected or the unit turned off.
If the measured pressure is out of range (for the chart selection), the display will read the actual pressure, but the pen
will not go beyond limit of the chart.

How to Set the C hart Speed and Range.

1. While in the RUN mode, press the MENU button. This will show the Beeper is ON (OFF) message. Press the
MENU button again and the display will present the setting for chart speed.

2. To select a longer chart speed, press the A button, for shorter chart speeds press the B button. Each time the A
or B button is pressed, the speed will change.
Whatever speed is on the display will become the chart speed
The available chart speeds are listed below;

31 Days 7 Days 12 Hrs. 3 Hrs.
24 Hrs. 6 Hrs. 1.5 Hrs.

3. Press the MENU button again to go to the chart selection menu. To change the chart range and chart number, press

the A or B button. Each time the A or B b ut ton is pressed, the range will change.

Whatever range is on the display will become the chart range.
Note that the chart number is displayed with the chart range for the users convenience.
The available chart ranges are listed below;

Pressure 1 Pressure 2

4. Press MENU to Proceed in MENU Mode. If no button is pressed for 30 seconds the recorder will
automatically return to the RUN Mode or to go to RUN Mode from here, press MENU once, then press B for RUN.

How to Set Single Tur n or Continuous Rotation

The recorder can be set to rotate chart continuously or stop after one revolution.

1. Press MENU until "Single Turn or Continuous" message appears.

2. Press A to toggle between Single and Continuous.

3. Press B to go to RUN Mode.

4. Press MENU to continue in MENU Mode.

ALARM AND DELAY

When pressure 1, pressure 2 or both measurements pass above or below the thresholds set in the menu function, the
CR4-KPP will execute a preset operation. T his operation is described as an Alarm condition or a Delay condition
and is referred to simply as Alarm or Delay.
Alarm indicates that one or both measurements are above or below the preset thresholds and the CR4-KPP is
sounding the audible alarm and has closed the relay contacts. The display will also be flashing the parameter that
has caused the Alarm condition.
Delay is a condition in which one or both thresholds have been passed, but the audible alarm and relay contacts are
not activated for a preset delay time. Delay is used to prevent nuisance and false alarms.

For Example:
The CR4-KPP has been set up at a manufacturing facility to monitor air pressure and water pressure. In the normal
course of operation short term drops in pressure will occur as a result of equipment placing demands on the system.
Without a short Delay time nuisance alarms would occur at every machine cycle.
By selecting a Delay time of 10 minutes the user can ignore short term drops in pressure caused by machine
operation but be alerted in the event of a real loss of air or water pressure.

The CR4-KPP allows the user to select one of five Delay times, zero Delay, 10 minutes, 20 minutes, 1 hour or 2
hours. The delay time selected will depend on the application and will vary from installation to installation
It is up to the judgment of the user to determine the best delay time for a given application. When a Delay time of
zero is used the Delay function is disabled. When a pressure threshold is passed the audible alarm and relay
contacts will close immediately. If a Delay time other than zero is selected the audible alarm and contacts will not
activate until one or both pressure thresholds been exceeded continuously for the period of the Delay Time. The
display will flash the parameter which has caused the Delay condition to alert the user that one or more thresholds
have been passed. At the end of the Delay time the audible alarm will sound and the relay contacts will close.

HOW TO SILENCE THE ALAR M: (Relay c ontacts remain closed .)

1. Press MENU and the display will show "Beeper is ON” message.

2. Press A to turn off alarm (only sound will be turned off, relay will be closed).

3. Press B to t urn alarm (sound) on.

4. Press MENU to continue in MENU Mode.

How to Set the Alarm & Delay

1. Press MENU button until alarm status message appears.

2. Press but ton A to scroll through options:
Alarm Disabled (If the alarm is disabled, you must enable the alarm to get the delay sections of
the MENU.)

Zero Delay
10 Min. Delay
20 Min. Delay
1 Hour Delay
2 Hour Delay

3. Press B to go to RUN Mode or MENU to continue in MENU Mode.

Pressure 1 AND Pressure 2 Limits

The Pressure 1 and Pressure 2 Upper and Lower limits allow the user to customize the alarm settings of the
CR4-KPP to provide the greatest degree of protection while at the same time preventing unnecessary alarms. Since
each application is unique, careful selection of the pressure thresholds are required to provide the maximum degree
of protection. Both pressure high and low limits may be set. If the Alarm is enabled, and any of these limits are
exceeded, the display will blink the reading that went out of limit. An audible alarm (Beeper) will sound and the
relay contacts will close after the set delay time. This delay time can be set as follows:

0 Delay
10 Min. Delay
20 Min. Delay
1 Hr. Delay
2 Hr. Delay

If the Alarm is not disabled, any of the four limits could trip the alarm, therefore all four limits must be set or the
alarm must be disabled if it is not being used.

SETTING THE LIMITS.
Pressure Limit part of MENU will not show if alarm is d isabled.

How to Set the Pressure 1 High Limit

1. Press MENU until "Pressure 1 High Limit" appears.

2. Press A to increase limit, B to de c rease limit, or MENU to go to Pressure 1 Low Limit.

The A or B button can be hel d down if moving pressure limit several PSI (BAR).

How to Set the Pressure 1 Low Limit

1. Press MENU until "Pressu re 1 Low Limit" appears.

2. Press A to increase limit, B to decrease limit or MENU to go to P ressure 2 High Limit.

How to Set the Pressure 2 High Limit

1. Press MENU until "Pressure 2 High Limit" appears.

2. Press A to increase limit, B to d e c r e a se limit or MENU to go to set Pressure 2 Low Limit.

How to Set the Pressure 2 Low Limit

1. Press MENU until "Pressure 2 Low Limit" appears.

3. Press A to increase limit, or B to decrease limit. Press MENU to return to RUN mode.

Setting pressure sensors to 0 PSI

Under certain conditions and over a period of time the pressure sensors may drift slightly off 0 PSI.
To re-zero the pressure sensors press and hold “MENU” and “A” buttons simultaneously while in the RUN mode
until the display indicates Initial Zero Pressure.
Release the buttons. The sensors have now been reset to zero.
Note that for this adjustment to maintain the accuracy of the pressure sensors the pressure at both sensors must
actually be at 0 PSI when setting the zero point.

PEN POSITION ADJU S TMENT

NOTE: The blue pen has a longer arm to allow it to move over the red pen. Therefore one pen will record at real
time and the other will lag or lead by 3/16".
In the normal course of operation charts and eventually, pens will have to be changed on the CR4-KPP. When this
occurs it may be necessary to adjust the pen position to match the reading of the display. This is most likely to occur
when changing a pen.

How to Adjust the Blue Pen Po s ition on the char t (Pressure 2).

1. Press the HOME button until the display reads "H oming the Pens Please Wait"

2. Press but ton A to select the pen adjustment menu.

3. Press but ton B to move blue pen in (toward hub) and button A to move blue pen out (toward edge of
chart).

4. Press MENU to select red pen adjustment menu.

5. Press MENU again if no adjustment of the red pen is required otherwise go to the “Adjust Red Pen “
instruction (next section).

How to Adjust the Red Pen Position on the char t (Pressure 1)

1. Press but ton A to move the red pen out (toward outer edge of the chart).

2. Press but ton B to move the red pen in (toward hub).

3. Press MENU to r e turn to the RUN mode.

Pressure Probes

Each probe contains the sensor needed to convert Pressure to the electrical
signal that the recorder uses to record and display.

Each probe will measure Pressure from 0 PSI (0 BAR) to 500 PSI (35 BAR)

The pressure sensor is media compatible and can be used with any gas or liquid that is compatible with 17-4 stainless
steel.

Calibration by Supco to NIST traceable standards is available as an option.

BATTERY BACKUP OPERATION

Battery backup allows the CR4-KPP to continue operation in the event of a power loss. Actual operating time on
battery will depend upon the condition of the batteries. With fresh alkaline batterie s the typical operating time will
be 48 hours (when operating on battery only). Alkaline batteries are essential for this type of applicatio n.
When the main power is lost the CR4-KPP will sense this and immediately turn off the backlight on the LCD
Display. A “B” will be displayed in the upper right hand corner of the display to advise the operator the CR4-KPP
is operating on battery power. No other indica tion will be visible. The pressure and chart recor ding will continue
until the batteries have been exhausted or the AC power is restored.
The CR4-KPP will monitor the battery power and when the batteries are almost exhausted, a "Low Battery"
message will appear on the display. The batteries should be replaced as soon as possible to avoid erroneous
readings. This prevents possible damage due to battery leakage and also assures that the CR4-KPP will remain in
operation in the event of another power failure.

The suggested battery backup consists of eight AA cells, however, a standard nine volt battery could be used to
provide approximately one hour of backup.

The following chart shows the life expectancy of various types of batteries.

1. Eight Alkaline AA cells 48 Hours

2. Eight Rechargeable Nicad AA cells 24 Hours

3. Standard 9 Volt Alkaline Battery 1 Hour

The life expectancy of the batteries is based only on the time when the
CR4-KPP is being operated on ba tte ries only.
It is good practice to replace these batteries every year.
Do not keep batteries in the CR4-KPP when not in use.

RS-232 Port

The CR4-KPP provides an optional RS-232C port to allow the user to connect the recorder to a computer or network
and allows continuous monitoring of the data being recorded. An adapter cable is supplied with this option to
facilitate connection to an external computer.
Data is transmitted every time the pressure sensors are sampled and is only interrupted during an update of the pen
position.
The data is delimited ASCII text and will transmitted as pressure 1 and pressure 2.
The port parameters are as follows;
4800 baud
8 Data Bits
No Parity
1 Stop Bit
