RKC INSTRUMENT SA200 Series Operating and maintenance instructions

SA200
General Description
SA200
Features
The SA200 is a new high performance temperature controller specifically designed for applications where panel space is critical yet maximum
control performance is required!
1/32 DIN size with dual display
Close vertical and horizontal mounting
Self-tuning and autotuning
Loop break alarm and temperature alarms
Digital communications with both MODBUS
and RKC protocols
Designed for close vertical or horizontal
mounting
The SA200 offers an optional RS-485 communications
interface for networking to computers, PLCs and SCADA
software. MODBUS or ANSI protocol can be selected. Up to
32 units, including host computer, can be multi-dropped on one
RS-485 communication line. When the communication feature
is selected, the external contact input is not available.
Digital communications
MODBUS/ANSI protocol (Optional)
RKC self-tuning offers the most advanced algorithm for precise
temperature control. Self-tuning is initiated at start-up and
when process parameters or conditions change. At these
times, new PID parameters are calculated for the best control
performance. With the unique RKC self-tuning, the controller
evaluates whether PID parameters should be maintained or
replaced, selecting the best setting for the controlled process. If
it is determined that the existing PID parameters can achieve
the best control for the process, the present PID parameters will
be retained and the new PID parameters will be canceled. Self-
tuning can be turned on/off in parameter setting mode. Self-
tuning is not available with heat/cool control.
In addition to self-tuning, the controller also has autotuning
(AT) so that either function can be selected for optimum process
control.
The SA200 allows you to mount several
units close together to make effective use
of control board or panel space.
A maximum of six units can be closely
mounted.
RKC self-tuning
Advanced algorithm for optimum control
The waterproof and dustproof feature protects the panel-
mounted instrument in severe environments or wash-down
conditions and conforms to IP66(NEMA4) standards.

SA200
Features
Control loop break alarm and
temperature alarms (Optional)
The control 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.
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 addition to the control loop break alarm, deviation (high, low,
high-low), process (high, low), set value (high, low) and band
alarms can be selected.
Digital contact input for external
switching (Optional)
An optional digital contact input is available for RUN/STOP and
SV1/SV2 switching. (RUN/STOP switching can also be
completed at the front key panel.) This function can be used
with the output from a timer, PLC, etc. When the
communication feature is selected, the external contact input is
not available.
Heat/cool control (Optional)
The heat/cool PID controller has heat and cool outputs for use where
process-generated heat exists. The controller allows the input of overlap
or deadband settings which can contribute to energy savings.

Easy maintenance
The internal assembly of the SA200 can be removed from the
front of a control board. It is easy to inspect, maintain or
replace the instrument because it does not require access from
the back of the panel.

*1 For waterproof and dustproof models, a rubber packing is added.
*2 Terminal cover is optional.
For mounting of the SA200, panel thickness must be between 1-10 mm.
When mounting multiple SA200s close together, the panel strength
should be checked to ensure proper support.
Two mounting brackets will be furnished for installation of the instrument
at either the top and bottom or sides.
Close vertically and horizontally mounted instruments cannot be
combined in one installation.

Warning
If the SA200s have waterproof/dustproof options, protection may be compromised by close mounting. Close vertical mounting is not available when a
shunt resistor for current input is used.
