General Description
The CB Series combines easy-to-use operation with the latest temperature control advances at a competitive price. With powerful new
features such as RKC's new self-tuning for precise automatic control, digital communications for networking, IP66(IP65) for waterproof/dustproof
protection and heater and loop break alarm capabilities to detect system failures, these controllers deliver exceptional process performance for
the most demanding industrial applications.

Bright, Easy-To-Read LED Displays
The CB Series features large, bright LED displays that have
been designed to be easy-to-read from greater distances.

Self-Tuning Algorithm
The CB Series offers a new self-tuning feature that is initiated
at start-up and when process parameters or conditions change.
In these situations, the controller evaluates whether the preset
PID parameters should be maintained or replaced by the latest
self-tuning parameters to achieve the best control for the
process. Self-tuning can be manually turned ON/OFF in the
parameter setting mode. This feature is not available with the
Heat/Cool control.
In addition to self-tuning, The CB Series has standard
autotuning (AT) so that either function can be selected to
achieve optimum process control.

Digital Communications
(Optional)
The CB series offers an optional RS-485 communications
interface for networking to computers, PLCs and SCADA
software in your plant. Up to 31 units can be interfaced on one
RS-485 communication line. MODBUS protocol is also available.
Heat/ Cool Control
The Heat /Cool PID control features heat and cool outputs for
use where process-generated heat exists. This allows the input
of overlap or deadband settings which contribute to energy
savings.

Features
Heater Break Alarm (HBA)
(Optional)
Loop Break Alarm (LBA)
(Optional)
The HBA detects a fault in the heating or cooling circuit and
displays actual amperage on the display on the front panel.
If the measured value becomes lower than the preset value, the
alarm is activated.
The loop break alarm (LBA) monitors and protects an entire
temperature control system. The LBA detects heater breaks,
thermocouple or RTD failures, short circuits, or the failure of an
operating device such as a mechanical or solid state relay.
The HBA function requires a current detector for measuring
and monitoring the current load.
When the PID computed value reaches 100% and the
temperature does not respond in a set time, the loop break
alarm is activated. Conversely, when the PID value reaches 0%
and the temperature does not respond accordingly, the loop
break alarm is turned on. In this example, the LBA uses
reverse action to control heat. For cool control, the LBA action
is reversed and becomes direct. LBA deadband is available to
suppress the influence of external disturbances.

Temperature Alarms
(Optional)
The CB Series provides a wide selection of alarm types to
configure up to two alarm contacts. The alarm Hold action is
configured in the controller. The alarm action is suppressed by
the Hold function at start-up until the process value has entered
the non-alarm range.
RUN/ STOP Mode
(Optional)
When it is necessary to turn off the control output, the STOP
mode is available to suspend control operation. To go between
these two modes, it is necessary to press the R/S key for one
second. When the control output is turned back on, the
controller returns to normal operation. The instrument monitors
the process value in the lower display in the STOP mode.
The RUN/STOP feature can be enabled/disabled in the
parameter setting mode.
