DESCRIPTION
TheTemp View Process Controller accepts either a 0 to 10 VDC or a 0/4 to
20 mA DC signal, precisely displays the input process signal according to the
programmable scaling points, and provides an accurate output control signal
(time proportional or linear DC) to maintain the process at the desired control
point. The controller’s comprehensive yet simple programming allows it to meet
a wide variety of application requirements.
In the PID control mode the controller operates with on-demand auto-tune,
which will establish the tuning constants. The PID tuning constants may be finetuned 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. The unit can be transferred to
operate in the manual mode, providing the operator with direct control of the output. The controller may also operate in the ON/OFF control mode with adjustable
hysteresis. A second setpoint is available to allow quick selection of a different
setpoint setting.
Dual 4-digit displays allow viewing of the process and setpoint simultaneously. Front panel indicators inform the operator of the controller and output status.
On some models, the main control output and the alarm outputs are field replaceable.
Optional alarm(s) can be configured to activate according to a variety of
actions (Absolute HI or LO, Deviation HI or LO, and Band IN or OUT) with
adjustable hysteresis. A standby feature suppresses the alarm during power-up

until the process stabilizes outside the alarm region. The second alarm can be
configured as a secondary PID output (heat/cool applications).
Optional Main Linear DC output (10 V or 20 mA) can be used for control or
process re-transmission 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 re-transmission, while the main Linear DC output is being used for control. The output range can be scaled independent of the input range.
Optional Remote Setpoint input (0/4 to 20 mA) allows for ratio control for
mixing and blending; allows for cascade control loops; 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 expand the controller’s flexibility.
The optional RS-485 serial communication interface provides two-way communication between a Temp View Process 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 Temp View Process
Controller on the line can be programmed separately from 0 to 99. Data from the
Temp View Process Controller can be interrogated or changed, and alarm output(s) may be reset by sending the proper command code via serial communications. PC software, SFT48, allows for easy configuration of controller parameters. These settings can be saved to disk for later use or used for multi-controller
down loading. On-line help is provided within the software.
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 Temp View Process 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 controller. An
independent and redundant process limit indicator with alarm outputs is strongly recommended.

FRONT PANEL FEATURES
In the normal operating mode, the unit displays the process value in the
upper display. One of the following parameters can be viewed in the lower display:
- Setpoint
- % Power Output
- Process Deviation
- Blank Display
The user scrolls through these parameters by pressing the D button. If
enabled, the control setpoint or power output (manual mode only) can be
directly modified in this mode.
In the normal operating mode, parameters are selected by use of the P button and modified by use of the UP and DOWN buttons. Parameters are then
entered by the P button, which advances the user to the next parameter.
Pressing the D button immediately returns the controller to the normal operating mode without changing the currently selected parameter.
HARDWARE FEATURES
A fast 100 msec input sampling rate provides quick controller response to a
process disturbance, thus providing excellent process control. Measurement
accuracy of 0.1% or better, provides close process control conforming to the
desired control setpoint value.
Low-drift, highly stable circuitry ensures years of reliable and accurate
process control. The recommended two year re-calibration interval is easily
accomplished via the programming menu.
REMOTE SETPOINT INPUT
The remote setpoint input facilitates the use of a remote signal to drive the
controller’s setpoint. The remote signal can be scaled independent to that of the
controller’s range. The controller’s response to local/remote setpoint transfers
can be programmed. Also, the remote signal is filtered by use of an adaptive
filter. With this filter, relatively large filtering time constants can be used without suffering from long settling times. The time constant and filter disable band
are programmable. Additionally, the remote signal can also be velocity limited
(or ramped) to slow the controller’s response to changes in setpoint. This
results in a steady control response with no overshoot.
LINEAR DC ANALOG OUTPUTS
The Main Linear DC output has independent scaling, programmable output
update time and filter (damping) time. These parameters permit flexibility in
process configuration. The output can be set for 0 to 10V, 0 to 20 mA or 4 to
20 mA ranges and can be configured for control or for re-transmission of input
or setpoint values.
A Second Linear DC output is dedicated for the re-transmission of the
process input signal. The output can be scaled and converted independent of
the input signal and Main Linear DC output. This output is isolated from the
input.
SETPOINT FEATURES
The controller setpoint can be protected from out of range values by programming the setpoint range limit values. Additionally, safeguards from inadvertent data entry can be programmed.
A second setpoint can be selected by the user input and/or through the front
panel.
The setpoint ramp feature can be used to control the setpoint value at startup or any time a setpoint change is made, at a user programmable rate. This
feature reduces shock to the process and helps to minimize overshoot.
INPUT FEATURES
A programmable input filter can be used to stabilize readings from a process
with varying or oscillating process characteristics, helping to provide better
control.
The programmable user input can be used to control a variety of functions,
such as auto/manual transfer of the controller, reset alarm output(s), etc.
OUTPUT FEATURES
BASIC OPERATION
The Temp View Process Controller controls a process by receiving a linear DC signal representing the process value, then calculating a control output
power value by use of a modified PID control algorithm. The unit controls the
system with the new output power value to keep the process at setpoint. The
PID control algorithm incorporates features which provide for high control and
low overshoot from process disturbances.
Programmable output power limits provide protection for processes where
excessive power can cause damage. Programmable output cycle time, output
hysteresis, and dampening can reduce output activity without degrading control accuracy. The main outputs can operate in PID, ON/OFF, or manual control modes.

CONTROL AND ALARM OUTPUTS
HIDDEN FUNCTION MODE *
In addition to the Linear DC output, there are up to three relay outputs available. Relay outputs can switch user applied AC or DC voltages for control or
alarm purposes.
The Hidden Function Mode is accessible from the Normal Display Mode.
The functions in this mode may be locked-out individually in Configuration 3
parameter (lock-out section).

AUTO-TUNE
The Temp View Process Controller has an auto-tune feature which, on
demand, automatically determines the PID control parameters for a particular
process. After completion of auto-tune, the PID parameters are automatically
optimized for that process and loaded into non-volatile memory. The operator
may view and modify the parameters as desired.
Auto-tune may be invoked either at start-up or at setpoint, depending on the
process requirements. An auto-tune programmable dampening factor produces
various levels of process control and response characteristics.

CONFIGURATION PARAMETER MODE
The Configuration Parameter Mode allows the operator to set-up the basic
requirements of the controller. It is divided into sections which group together
related programming steps, such as inputs, outputs, alarms, etc. Upon completion of each section, the program returns to the Configuration Access Point
allowing the user to return to the Normal Display Mode.
RS-485 SERIAL COMMUNICATIONS
The RS-485 communications option allows the connection of up to 32
devices on a single pair of wires with a distance of up to 4,000 feet and a maximum baud rate of 9600. Since the same pair of wires are used for both transmit and receive, only one way communication is possible at any given time.
The controller has a programmable response time to allow the host device adequate time to release the communication line for a transmission.
Selected parameters from the Temp View Process Controller can be interrogated or changed, and alarm output(s) may be reset by sending the proper
command code via serial communications. It is also possible to invoke Autotune through the serial port. Serial communications used with software allows
for easy controller parameter configuration by computer.
