Safety hazard symbol notice
Documentation needs to be consulted in all cases where the symbol is used to find out the
nature of the potential hazard and any actions which have to be taken.
Considerations specific to the CN6 temperature controller
Warning: To avoid electric shock, do not remove protective panels from system
modules. The components within are not user-serviceable.
Warning: To avoid electric shock, observe these precautions:
• Use SVT-type power cords in the United States and HAR-type power cords, or
better, in Europe. For requirements elsewhere, contact your local Waters distributor.
• Inspect the power cords for damage, and replace them, if necessary.
• Power-off and unplug each module before performing any maintenance operation
on it.
• Connect each module to a common ground.
Warning: To avoid spinal and muscular injury, do not attempt to lift a system module
without assistance.
See also: For safety considerations regarding specific system modules, consult the appropriate
information on the user documentation CD.

Audience and purpose
This guide is intended for individuals who operate the six-zone temperature controller module
(CN6). It gives an overview of the technology and operation of the temperature controller module.
Intended use of the six-zone temperature controller module
Waters designed the six-zone temperature controller module (CN6) for use in liquid
chromatography applications. The temperature controller module is not intended for use in
diagnostic applications.
ISM classification: ISM group 1 class A
This classification has been assigned in accordance with CISPR 11 Industrial Scientific and
Medical (ISM) instruments requirements.
Group 1 products apply to intentionally generated and/or used conductively coupled radio-
frequency energy that is necessary for the internal functioning of the equipment.
Class A products are suitable for use in all establishments other than residential locations and
those directly connected to a low voltage power supply network supplying a building for domestic
purposes.
There may be potential difficulties in ensuring electromagnetic compatibility in other environments
due to conducted as well as radiated disturbances.

1Overview
The six-zone temperature controller module (CN6) can control up to six independent proportional-
integral-derivative (PID) control zones with thermocouple inputs. You can operate the CN6
through ChromScope software or the optional front-panel display.
1.1 Major components
The following diagrams show the six-zone temperature controller module’s major components.
Figure 1–1: Front view
Z1–Z6 LEDs – Indicates when power is being applied to the solid state relay. This LED is
green when power is being applied to the solid state relay and unlit when no power is being
applied to the relay. The LED is steady green when the actual temperature is several
degrees below the set temperature and flashing green as the actual temperature reaches
the set temperature.
Alarm LED – This LED is red when an internal error occurs and unlit when no errors are
detected.
Power LED – Indicates the power-on or power-off status of the module. This LED is green
when power is on and unlit when power is off.

Figure 1–2: Rear view
FUSES WARNING
!
Thermocouple inputs (Z1 to Z6) – Standard, miniature-style thermocouple connectors that
can accept any type of thermocouple. They are marked and use the standard thermocouple
type color coding. To avoid incorrect temperature readings, always use the correct type of
thermocouple.
RS-232 cable connector – When connected to this port, the RS-232 cable allows the
temperature controller module to communicate with a computer running under ChromScope
software control. The connection must carry all nine signals (including ground) from the
computer. For more information, see the ICM online Help.
Fuse holder door – Accesses the fuse holder and fuses.
On/off switch – Powers the module on and off.
April 4, 2017, 715005356 Rev. A
Page 10

Power input – This is the power supply cord connector. The six-zone temperature controller
module uses a universal power input module, and no internal changes are required when
changing voltage or frequency. When changing voltage, be sure to install the correct fuse
and fuse holder.
Solid-state relay outputs (Z1 to Z6) – Thermocouple input channels that can control a solid-
state relay to turn a heater on or off for temperature control. The output control has the
same label as the corresponding control thermocouple. The controller emits a 24 VDC
signal to turn the relay on, and a <3 VDC signal when the relay is in the off condition. The
temperature controller module allows a maximum of 50 mA per control channel and
mechanical relays are not recommended.
Requirement: Select only the J-type thermocouple and use only J-type connectors and
connecting wire. Selecting other thermocouple types or using other types of connectors and
connecting wire will result in temperature measurement errors.

Page 15

Item Description
Status Valid entries are:
• Disable — When selected, the primary regulation output is forced to
the off state. If the secondary output is configured as type "on/off", it is
forced to the off state. If the secondary output is configured as type
"alarm", it maintains the status enforced by the alarm conditions.
• Manual — When selected, you can change the primary output power
value. If the output is configured as type "on/off", only the values 0%
and 100% are allowed. Intermediate values are allowed when the
output is configured as type "SSR".
• Auto — When selected, the output is controlled according to the PID
(proportional-integral-derivative) values and current set points.
• Tuning — When selected, the temperature oscillates around the set-
point value. At the end of the procedure, the PID parameters are
automatically calculated and updated, and the regulation mode is
switched to "automatic". The unit can perform only one auto-tuning
procedure at a time. If you attempt to auto-tune more than one zone
simultaneously, the last setting is not applied and the operating mode
of the second zone is forced to "disabled". The operating mode of the
first zone that was set to auto-tuning is maintained, and when this
zone's auto-tuning procedure terminates, you can auto-tune another
zone.
