ABOUT THE CP6, CP7, AND CP8
The CP6, CP7, and CP8 are a new programmable controller based on a 16-bit microprocessor designed for
Nor-Lake Inc. Scientific control panels. The control panels are made up of a microprocessor-based MAIN
BOARD equipped with a set of terminals used to connect the board to the controlled devices (i.e.: valves,
lights, fans, and humidification, alarm triggers). The program and the parameters are saved permanently in
the FLASH memory, preventing data loss in the event of power failure (with-out requiring a backup battery).
The control panel also includes a microprocessor-based TERMINAL unit complete with display, keypad and
led indicators allowing you to easily set the main control parameters (set-points, bands, alarm thresholds) and
carry out the main working operations (on/off, displaying controlled variables). Connection between the
terminal unit and main board is necessary only when programming the control panels’ basic parameters.
The basic sequence of operation is:
CP6 - on/off control using a pump down solenoid
CP7 and CP8 - cooling and heating using hot gas bypass using either a solenoid or by a proportional
modulating electronic valve
CP8 - activate the humidifier as needed when the humidity falls below the set point
CP8 - activate the dehumidifier as needed when the humidity exceeds set point
Dual mode defrost timer; Time initiated –Time terminated or Time initiated –Temperature terminated
In addition to the basic sequence of operation, optional features are available:
two display options using LED and Graphical displays
networking to a central command computer, or to an existing building automation system
monitor the sensors, compressors and heaters for failure. On a sensor failure, the applicable systems are
disabled. On a compressor failure by low or high pressure, the compressor is locked out and other
compressors substituted. On a heater failure the heaters are locked out, but automatically reset.
multi channels of on/off light control
day/night settings for Temperature and Humidity
redundant system operation of two units with automatic crossover
The CP6, CP7, and CP8’s are truly one of the most powerful and flexible controllers available today.
SENSOR LOCATION
The location of the sensors is very important. All sensors should be positioned away from electromagnetic
noise. The product temperature sensor should be immersed in glycerin or other suitable medium that
thermally simulates the product. The glycerin well/product sensor is normally mounted on the wall near the
door and should be mounted at a height that will best reflect the product storage height, normally 40” above
the floor. For optimum temperature control the air temperature sensor should be mounted at a location, out of
the direct discharge of the evaporator coil, that best reflects the median temperature of the room. If the sensor
lead is not long enough, the lead may be extended using 18 gauge wire. The humidity sensor (CP8 Series)
should be mounted at a height that will best reflect the product storage height, normally 40” above the floor.
It is critical that the humidity sensor is located out of any direct air stream or discharge from devices;
evaporators, door openings, humidifiers, dehumidifiers, heat from lights, etc. If the sensor lead is not long
enough, the lead may be extended using 18 gauge wire. After the sensors are mounted, seal the hole in the
wall where the leads were fed with silicone sealant to prevent airflow through the hole.

PLASTIC BUTTON FUNCTIONS
1. On/Off: turns the system on and off. This will include the room lights, outlets, refrigeration, heating, and
humidity control. The green LED lit behind the button indicates that the unit is ON. WARNING:
DISCONNECT ALL SYSTEM POWER BEFORE SERVICING ANY EQUIPMENT!
2. Alarm: by pressing this button you can display the active alarms, reset them manually or silence the
buzzer. When the red LED indicator lights up, at least one alarm condition has occurred.
3. Up arrow: moves upward through the program windows and increases the values of the control parameter
when the cursor is in a parameter field (no backlight).
4. Down arrow: moves downward through the program windows and decreases the values of the control
parameter when the cursor is in a parameter field (no backlight).
5. Enter: moves the cursor between parameter fields and confirms the set data. The button is backlit
(yellow light) and indicates that the unit is being powered.

CONNECTION
The display unit is connected to the control board by a 6-wire standard phone cord of up to 1,000 feet in
length.
NOTE: A short, special phone cord is supplied with the controller. Connect a standard 6-wire phone cord
expansion to the end of this cord. DO NOT REPLACE THE SPECIAL CORD as this cord is
reversed from the normal phone cord. The control will not work if only a standard phone cord is
used.

STARTING UP AND OPERATING THE NOR-LAKE CONTROL
On first power up of the Nor- Lake Inc. unit, the CP6, CP7, or CP8 display will light and display the opening
screen:
Notes: 1. After 1 minute the screen will default to the system status screen.
2. To move to the next screen the cursor has to be positioned in the upper left-hand corner
of the current screen.
3. The ENTER key will move the cursor in the current screen.
KEY:MENU
Pressing the MENU key will display the following screen. The MENU screens are display screens only to
change set points the values must be entered at the corresponding screens. To view screens progressively,
use the down arrow key.
MENU 1
Displays product temperatures and the room humidity. Humidity will only be displayed if the
humidifier or dehumidifier control has been enabled. The lower line displays a second product
temperature.
Note: Product 2 temperature will only be displayed if an additional sensor is installed and the
sensor is enabled on System Setup 3.
MENU 2
Displays system demands. The bottom line is used to show the status of the compressors and
could show the conditions:
C1/C2:ON when air temperature is above the room temperature set point.
C1/C2:OFF when air temperature is at or bellow the room temperature set point.
HT1/HT2:ON when the auxiliary heaters are on.
C1/C2:DF when the system is in a defrost cycle.
C1/C2:ERR when the compressor alarm is active.
Note: C1 is for compressor #1. C2 is for compressor #2 and will only be displayed for systems
equipped with two compressors.

Ramp and Soak Example
The following example will ramp from 4.0°C to 10.0°C every Monday from 06:00 to 12:00. The
temperature will remain at 10.0°C until Wednesday at 06:00 when it will begin ramping the set point
down to 4.0°C at 12:00 Wednesday. The set point will remain at 4.0°C until Friday at 06:00 when it
will begin ramping the set point up to 10.0°C at 12:00 Friday. The set point will remain at 10.0°C until
Sunday at 06:00 when it will begin ramping the set point down to 4.0°C at 12:00 Sunday. The
temperature set point will remain at 4.0°C until the schedule repeats Monday at 06:00.
It is recommended to fill out the Ramp and Soak worksheet on page 47 of this manual before

Enter the start and end points for the demand, which is based on the temperature set point and
proportional band. The Start set point is the minimum proportional signal and the End set point is
the maximum proportional signal. As the actual reading moves from the set point within the
proportional band the signal will change proportionally to bring the actual reading back to the set
point.
PROP 3
Press the ENTER key to move the cursor to the set point data field. Use the Up or Down Arrow
key to increase or decrease the value. When the correct value is displayed press the ENTER key to

TYPE is set to either P (PROPORTIONAL) or PI ( PROP + INTEGRAL). If PROP + INTEGRAL
control is chosen, the user must enter the INTEGRATION TIME> as well. Also, enter the
proportional band for control. Proportional + integral control works as follows: When the actual
reading is away from the set point for more than the integration time, the proportional signal
strength is increased to help drive it back to set point.

within the proportional band the signal will change proportionally to bring the actual reading back to
the set point.

COOL 2: Time between is the minimum time between compressor 1 ON and compressor 2
ON (seconds). Rotation enables/disables time rotation of the compressors. Rotation time
is the length of compressor run time between rotation periods (hours).
COOL 3
COOL 3: When compressor type is set to ONE, the controller will operate only the first
stage of cooling. When the compressor type is set to TWO, the controller will operate two
compressors. The first compressor will come on based on demand and the second will
come on by temperature based on the set point + the band + the stage 2 differential
