General Description; Safety Summary - Omega CN63100 Series User Manual

GENERAL DESCRIPTION

The CN63100 Controller accepts signals from a variety of temperature
sensors (thermocouple or RTD elements), while the CN63300 Controller
accepts either a 0 to 10 VDC or 0/4 to 20 mA DC input signal. Both controllers
precisely display the process, and provide an accurate output control signal
(time proportional or linear DC) to maintain a process at the desired control
point. The controllers' comprehensive programming allows them to meet a
wide variety of application requirements.
The controller can operate in the PID control mode for both heating and
cooling, with on-demand Auto-Tune, which will establish the tuning
constants. The PID tuning constants may be fine-tuned by the operator at any
time and then locked out from further modification. The controller employs a
unique overshoot suppression feature, which allows the quickest response
without excessive overshoot. Operation of the controller can be transferred to
manual mode, providing the operator with direct control of the output. The
controller may also be programmed to operate in the ON/OFF control mode
with adjustable hysteresis.
Dual 4-digit displays allow viewing of the process/temperature and
setpoint simultaneously. Front panel indicators inform the operator of the
controller and output status. The control output and the alarm outputs are
field replaceable on select models.
Optional alarm (s) can be configured to activate according to a variety of
actions (Absolute HI or LO, Deviation HI or LO, Band IN or OUT, and Heater
Current Break) with adjustable hysteresis. A standby feature suppresses the
alarm during power-up until the process stabilizes outside the alarm region.
Optional Main Linear DC output (10 V and 20 mA) can be used for control or
retransmission purposes. Programmable output update time reduces valve or
actuator activity. The output range can be scaled independent of the input range.
Optional Second Linear DC output (10 V or 20 mA) provides an
independent process retransmission, while the main Linear DC output is
being used for control. The output range can be scaled independent of the
input range.
A Remote Setpoint input (0/4 to 20 mA) allows for cascade control loops,
where tighter control quality is required; and allows for remotely driven
setpoint signal from computers or other similar equipment. Straightforward
end point scaling with independent filtering and local/remote transfer option
expands the controller's flexibility.
The optional RS485 serial communication interface provides two-way
communication between a controller and other compatible equipment such as
a printer, PLC, HMI, or a host computer. In multipoint applications (up to
thirty-two), the address number of each controller on the line can be
programmed from 0 to 99. Data from the controller can be interrogated or
changed, and alarm output(s) may be reset by sending the proper command
code via serial communications.
The unit is constructed of a lightweight, high impact plastic case with a tinted
front panel. The front panel meets NEMA 4X/IP65 specifications when properly
installed. Multiple units can be stacked horizontally or vertically. Modern
surface-mount technology, extensive testing, plus high immunity to noise
interference makes the controller extremely reliable in industrial environments.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in
the manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
Do not use the controller to directly command motors, valves, or other
actuators not equipped with safeguards. To do so, can be potentially harmful
to persons or equipment in the event of a fault to the unit. An independent and
redundant temperature limit indicator with alarm outputs is strongly
recommended.
CAUTION: Risk of Danger.
Read complete instructions prior to
installation and operation of the unit.
