Safety Warnings

In addition to presenting a potential
fire hazard, high voltage and high
temperature can damage equipment and
cause severe injury or death. When
installing or using this instrument, follow
all instructions carefully and use approved
safety controls. Electrical connections and
wiring should be performed only by
suitably trained personnel.

Do not locate this instrument where it is
subject to excessive shock, vibration, dirt,
moisture, oil, or other liquids. The safe
operating temperature range for this unit
is 32°F to 140°F (0°C to 60°C).

Installation

Pre-Installation Instructions

1. Inspect shipping carton for obvious
signs of mishandling.

2. After removing the controller from the
shipping carton, inspect it carefully for
damage. Never attempt to install
and use a damaged unit.

3. Verify that the ordering code number
indicated on the side of the controller
matches what was ordered.

Figure 1. Case Dimensions

Prior to mounting the CN8100 in your
panel, make sure that the cutout opening
is of the right size, 3.622" x 3.622"
(92 mm x 92 mm), and deburred to
enable a smooth fit.

A minimum of 5.0" (127.0 mm) of depth

behind the panel is required.

Mounting

Before installing the CN8100, ensure
gasket seats evenly around edges of unit
and that there are no breaks or tears in
the gasket.

Insert the CN8100 through the front
panel cutout, slide mounting “U” bracket
around unit and secure it with the
screws provided.

Gasket should be evenly compressed
around all sides to provide liquid-tight
mounting.

Figure 3. Wiring Connections

Wiring

IMPORTANT: All electrical wiring

connections should be made only by
trained personnel using Class 1 wiring,
and in strict accordance with the National
Electrical Code and local regulations.
Both of the incoming power lines should
be fused with 2AG, 0.5 A maximum
rated fuses.

The CN8100 controller has built-in
circuitry to reduce the effects of electrical
noise (RFI) from various sources;
however, power and signal wires should
always be kept separate. We recommend
separating wires into one bundle for
power (from line power and output)
and one bundle for signal (from
thermocouple).

The CN8100 power supply accepts 100
through 250 Vac and 120 through 250
Vdc line power without any switch
settings or polarity considerations.

Operation

Omega CN8100 Digital
Temperature Controllers

Just a few easy steps are required before
your CN8100 can be placed into service.
After completing the mounting and wiring
procedures as previously instructed, set
each controller parameter using the
simple front-panel keys as instructed.

Power On

When power is first applied to the
CN8100, all segments of the LED display,
as well as the discrete indicators, will
be momentarily illuminated while the
instrument goes through a series of
diagnostic checks to verify proper
operation of the unit. A software version
will then be displayed, e.g., . The
last two digits of this code indicate the
software revision supplied with your
controller. Please provide this revision
number when contacting us regarding
your unit. This display is followed by a
mnemonic code representing the
model type.
